Wood is one of the two oldest building materials that people have been using continuously (the other is stone)! But, being organic, wood has never been as long-lasting as stone. And, it becomes worse if they are outdoor wooden structures! Water, moisture, ultraviolet rays, and fungus such as mildew cause those structures to rot shortly! Fortunately, modern science has introduced Sealer, a proven and long-lasting solution to this problem. Naturally, people search for the best outdoor wood sealer to safeguard their precious exterior wooden objects. Research shows Ready Seal 512 is the first-preference sealer (both by users and experts) for its value and versatility. But if you need a high-tech premium protector with long-lasting marine performance, go for Seal-Once Marine. The ongoing wood sealer reviews probably may help you understand why.
Best Value and Versatility
The UV-resistant, moisture-proof, antifungal, and oil-based coat adds natural color to wood and seals it from water, moisture, ultraviolet rays, mildew, and other potential threats. It keeps the wood texture and grain visible and attractive. Many wood projects require staining before sealing, which has to be purchased separately. Combining these two, Ready Seal cuts the extra costs, reduces the application time, and ensures a classy and high-end finish over the wood, which stays longer as it is.
Premium, Long-Lasting and High-Tech
The premium quality water-based sealer & stain works like an oil-based one that penetrates deep in wood’s surface to give fibers a coat at cellular level. The special marine formula keeps wood protected from mildew, algae, and dampness even at the most moisturous areas like near ponds and rivers. Additional UV resistance safeguards from bad rays. Wood will be free from decay, warping, cupping, and rot. Seal-Once is non-toxic and has minimum VOCs, making it the safest coat.
Best Outdoor Wood Sealers List - For Each of Your Demand
Best Wood Sealer (Overall) - Ready Seal 512 Exterior
Despite having relatively more prominent brands, we have indicated at the outset as to why we have made Ready Seal an overall priority on our list - for versatility, and value for the money. Sherwin-Williams or Thompson's WaterSeal was certainly in our consideration. But because they are more expensive, we have focused more on finding the same quality sealer at a relatively low cost, and Ready Seal is the result.
The most important aspect that Ready Seal ensures is that it makes the wood's natural beauty more attractive, allowing the grain and texture to remain visible. It is semi-transparent and mainly built for exterior wooden projects.
The sealer penetrates deep inside the wood surface and creates a highly-protective waterproof coat being dried quickly. While it may not provide as much protection as the Seal-Once Marine ensures to wooden structures installed near an overly moist place like near a pond or lake, Ready Seal can guarantee 100% protection to any other outdoor wooden objects from mildew, molds, and moisture. Additional UV-resistance system prevents any damage and decay from UV rays.
Many wood projects need to be stained before getting sealed, and you generally have to purchase the stain separately. But Ready Seal is a perfect combination of two - stain and sealer. You need not to apply stain separately followed by a sealer coat. Instead, a single Ready Seal coat serves as both staining and sealing, cutting the extra costs, reducing the duration of application, and ensuring a satin finish over the wood that stays longer as desired.
The sealer does not contain linseed oil and meets the USA's current requirements regarding the minimum volatile organic compound. Impressively, we have found no reports of hand stains from users so far. Although oil-based, Ready Seal is a proven biodegradable sealant, so if you would not deny it being an eco-friend.
Anyway, How to Apply the Ready Seal?
Before applying to any outdoor wooden structure, it is essential to clean all dust, dirt, mildew, oil, and other stains from the wood surface, even if it requires stripping. Then, dry the wood completely, which may require around 48 hours or twice subject to weather conditions. You should use a dust mask, nitrile gloves, a ball cap, and safety glasses while blending and applying the sealant coat.
Blend more than one container for ensuring color consistency, particularly when you want a deep pour. Do not dilute the stain, as it will degrade the formulation and reduce the efficiency of sealant. Take a brush or roller to apply the sealer. But an airless sprayer (should have a long hose) will probably be the right choice, as it will enable you to carry the tank around. However, you can get the job done with a cheap garden sprayer. Use a small spray tip, as will help to ensure the necessary force of stain, which is a bit thicker than water.
A single coat should offer the best finish for wood, but if you feel a second coat is required, wait for a minimum of 45 minutes in between two coatings. The coat should dry within any time from 48 hours and 72 hours, which varies mainly because of surface porosity, temperature, and humidity. The entire process neither will require back brushing nor leave runs, laps, or streaks. Initially, the surface may look darker when Ready Seal is applied, but it will gradually get back the true tone what it meant to be.
The stain on your applying equipment needs no special treatment to clean up when done. But it is always better to use mineral spirits or any paint thinner to get the job done.
How Much Area Does it Cover?
The sealer-come-stain has numerous colors, including natural cedar, dark walnut, redwood, light oak, and golden pine from where you can choose your desired one. It comes in two different sizes - 1 gallon, and 5 gallons. But how much area do they cover?
We should not give a straight answer to this question; instead, explain with a close to reality example. You can cover around 1000 square inches of a wooden surface with a 5-gallon Ready Seal. You may even include a bit more area, but never when it is an older surface, where you require much stain & sealer for a relatively narrow space.
What are the Downsides?
When about 90 percent of users express their satisfaction with a product, it should be understood that it has fewer downsides. However, this does not mean that it is flawless. The same is true for the Ready Seal. Therefore, our responsibility is to find out even its minor flaws, although we count it as the best exterior wood sealer.
We noticed a few have suggested using it for indoor structures, but we do not recommend it as it produces a strong odor, which may not be suitable for your indoor environment.
It takes around 48 hours to 72 hours or even more sometimes to cure properly, which is a downside compared to many other competitors' curing time.
As the darker color lightens over time (manufacturer claims 14 days for achieving the true tone), it is tough to guess the accurate result of what you will receive at the end. Although there is no reason to think that color will become too unattractive, this slow process creates confusion.
Do you think these should be deal-breakers? We don’t think that way, as we found many other competitive sealants having similar to this or even more downsides. So, the Ready Seal Stain Sealer should be the one ensuring the best finish for outdoor projects with its versatile staining and sealing capacity, which is more worthy than money spent for it.
Premium Long-Lasting Sealer - Seal-Once Marine Penetrating
Since its inception, Seal-Once has been effortlessly using nanotechnology in wood sealers and stains to make those completely water-proof, environment-friendly, and long-lasting for almost two decades. They have taken the innovation to a different level of success, and they are the leader here. The Seal-Once Marine Penetrating Wood Sealer is a glorifying example of their work, the long-lasting stain & sealer in our list.
It is a water-based sealer & stain that works like an oil-based one. For having the superior nanotechnology, Ready Seal Marine penetrates deep in wood’s surface to give fibers a super flexible and breathable coat at the cellular level allowing evaporated water to escape, while other top-coat sealants trap water vapor under the surface. If you don’t know, the vapor of water, if not escaped, causes peel and crack on the surface coating and substrate, leaving those susceptible to further (quicker) damage.
Thus, any wood gets protected from mildew, algae, and dampness even at the most moisturous areas like near ponds and rivers when you use Seal-Once. That’s why experts call it the best water sealant for marine wood projects, such as boat decks, piers, retaining walls, etc.
Marine Seal wood water sealer is simultaneously good for new and old wood, and it helps to age the wood naturally. Being non-film forming, it does not alter the original beauty of woods at any phase of application.
As said, the Seal-Once Marine is also applicable as a stain; you can use it to increase the organic grain of the wood. A total of eleven different color tints are out there, making it a source of diversity. Additional UV resistance safeguards from harmful UV rays. Wood will be inhibited from decay, warping, cupping, cracking, splitting, and rotting.
The best marine wood sealer is non-toxic and has minimum VOCs, low odor, non-flammable, and non-ozone depleting, making it one of the top three eco-safe wood treatment agents. It does not contain phosphorus compounds, nitrates, or heavy metals like many other oil-sealants. You can even apply it to any wooden structure above open water, and there will be no harm to marine life.
How to Apply the Seal-Once Marine?
Whether as a professional or DIY man, you must clean all old coatings, dust, dirt, grime, mill glaze, mildew, oil, and other stains from the wood surface before applying any sealer, including this one, to any outdoor or waterside wooden structure. Although the manufacturer suggests using Seal-Once Wood Cleaner for the best results, we think the regular cleaning process is enough. Never apply seal marine unless the wood is completely dry after cleaning. Take a dust mask, nitrile gloves, a ball cap, and safety glasses, as they will always keep you protected while blending, staining, or sealing.
Use a synthetic brush, or a garden pump sprayer (airless or air-assisted) to apply the first coat. We suggest preferring an airless sprayer with a long hose. It is better to use the medium to coarse spray pattern with 15-17 tips, as suggested by the manufacturer. It is wise to back brush for flawless results while spraying (for your remembrance - you need not do any back brush while applying Ready Seal 512, our first choice).
You are always allowed to give a second coat, if the wood is still damp, only when the first coat is penetrated well. So, wait until that happens, but do that must within one hour of the first coat. Make sure you’re applying coats under shade, not direct sunlight. Use warm and soapy water to clean brush and sprayer when done.
How Much Area Does it Cover?
Coverage varies based on the wood surface porosity. However, the manufacturer has a helpful instruction regarding this - you probably can cover an area between 250 square feet and 350 square feet using 1 gallon of Seal-Once Marine Penetrating Sealer. But according to our experiment, the coverage should be something from 200 to 250 square feet. It comes in two different sizes - 1 gallon and 5 gallons; therefore, the 5-gallon unit can approximately cover around 1000 to 1500 square feet based on porosity.
What are the Downsides?
We noticed no significant downside of the stain sealant that you may regard to deny it from our list of preferences. You may count the discrepancy between the producer's claim and reality regarding the coverage. You see, we have mentioned a coverage less than 50-100 square feet than the claimed coverage. Seal-Once Marine indeed covers less area than estimation, especially when it comes to weathered wood. It will help if you remember this while using it.
We noticed complaints regarding the inefficiency of stain color tint, which we mostly consider as an application error by users, no way tint inefficiency. So overall, this is a super recommendation for users searching wood water sealers.
Best Waterproof Sealer - Thompson’s WaterSeal Advanced
After a long journey of one century, the Thomoson's WaterSeal is a name of reliability, irresistible in the world of sealants and stains! No other brand has the dominance and product variation that it has. It has a reputation for understanding trends, and demonstrating the use of potential technology in this industry. Interestingly, if you don't know, Thompson's parent company is Sherwin-Williams! The Advanced Natural Wood Protector is one of the significant sealers from the brand, particularly known for its waterproofing capacity.
The protector is formulated for wood and does the job (offering maximum protection) in a single-coat. Advanced protection against water damage has made it the best waterproofing sealer for wood. The coating resists any potential threats to your outdoor decks and wooden projects, including, but not limited to, mildew, moisture & water, UV rays, and fading. But it maintains the natural texture and grain of the wood, and you can choose waterproofing stain color from five different options.
It will not offer any short term richness to your wood that you can get from a flashy oil like sealant, instead, the protection from moisture and water shall be constant and continuous for two years as advertised, except for any worst case scenario.
Thomson’s wood protectors mean - natural texture with long term protection, not attractive outfit with substandard protection.
It is for those who need to go fast, as it has a super quick curing record. It dries before an hour of application, and takes only a day (24 hours maximum) to cure completely. A thick and goopy consistency of the sealer makes it easy to apply, where a thick one-coat is enough. No recoating, no further mixing, no waiting, no wastage of time!
It is a water-based formula and easy to clean after applying. Suitable for decks, fences, and nearly all exterior furniture and wooden projects as long as they are dry enough, regardless of being new, old. If it is pressure-treated, you should not apply any sealant including this one for the first year. You can cover around 200 square feet using 1 gallon of Thompson's Advanced water seal, which may increase or decrease slightly based on wood porosity.
But you have to spend some more bucks from your bank, as it is expensive compared to many of its counterparts. Do not get surprised if you notice yellowing after coating, as some users have also complained about this. As long as you are concerned about the facts, the WaterSeal Advanced Wood Protector is your savior!
Best Deck Sealer (All Weather) - Olympic Stain Maximum Waterproofing
Deck is the first thing that comes when thinking of external wooden structures. It has always been one of the essential parts of a house. Although you can make an exterior deck with various materials, it is probably impossible to get such a natural, attractive and aristocratic look as wood. So there is always a preference for wooden decks, although they are expensive and difficult to maintain. But homeowners have never been stingy, and quality sealers and stains have helped them the most.
Olympic Maximum Clear Waterproofing Sealant is one of those. So far, it is the best creation (sealant) of Olympic Stain, a highly-trusted brand in the USA since 1938. We have enlisted. The advanced waterproofing and SunBlocking UV defense mechanism strengthen wooden decks and prevent those from wearing, fading, cracking, and decaying, making those long-lasting with the natural beauty they have. It also keeps decks protected longer from algae, mildew, and other organismic threats. It is our first choice for the deck and a reliable shield for almost any kind of exterior object made of any wood.
The most distinctive feature of the sealant is its all-weather applicability, allowing you to apply it at any time in any condition. Being weather-ready, it will offer you excellent and similar results every time. The feature facilitates you with some great conveniences - for instance, you can clean, stain and seal on the same day! Extreme cold (as low as 35-degree Fahrenheit), excessive heat, or even after the rain, you can apply it, as the stain is rain-ready only after 8 hours. For excessive hot surfaces, you just need to mist it lightly before applying, that’s it. Application is pretty much easy, and using a roller or sprayer with a brush should do the job. Back brushing will offer far excellent results.
Decks need the right amount of stain and sealer, as they used to come in contact with many damaging substances, including water, moist, mildew, UV rays at a significant level. A thin coat should be enough if it is clear, semi-transparent, or toner stains, while two thin layers are instructed in terms of solid stains. Applying to several boards at a time, leaving a wet edge, shall help you avoid lap marks. A 1-gallon Olympic Maximum sealant should cover around 250 square feet deck area, which may be increased based on the wood's porosity. You can cover both sides of a 25 feet by 6 feet fence with the same amount of stain sealant.
It is not quite an expensive sealant than many of its counterparts that are particularly built for decks but offers a super reliable result. However, for premium quality and more long-lasting results, rely on ToughTimber Waterproof Deck Sealer, a high-end deck sealant. We could not get it as our first choice for decks just because of less availability. But if you find this available, go for it without a second thought. Apart from the wooden deck, there is another type of deck known as a composite deck. This type of deck requires specific sealers, such as SaverSystems, the best composite deck sealer.
Best Clear Wood Sealer - Thompson's WaterSeal Protector
Although Olympic Stain did really well in the race to choose "Clear Sealant", it eventually lost the place to Thompson’s WaterSeal. However, Olympic Stain has been selected top for the deck sealing tasks (explained earlier), and that is one among others why it is not the best clear sealant. Moreover, Thompson's Clear Wood Protector has some distinctiveness for the position.
Why need a clear sealer? There is no substitute for a clear sealant to expose the true color of wood with more beautification. It saves you from having to spend on painting. However, the most useful thing is that it is resistant to oxidation and fading. Being the top choice, Thompson's Clear Sealant is capable of fulfilling all of those besides many more things.
It is oil-based and particularly built for outdoor wood protection. The low VOC clear sealant requires a maximum of 48 hours for full curing. It is highly water damage preventive and maintains wood’s nature resisting mildew and UV rays as long as advertised, except for any application error.
A regular garden sprayer with a paintbrush should do the job. However, you may find it tough to open the container and end up using a hammer. Compliance with temperature as instructed in manual does matter - applying at any temperature, particularly lower than recommended will result in longer curing time. It doesn’t take much sealer to apply, as a little (even a single coat) can give your desired result. If you get it done by a single coat, we suggest redoing the coat after a year. Although the manufacturer calls two years, we think that it is for thick double coats.
Applicable for decks, outdoor tabletops, fences, and other exterior wood objects. But it is essential to maintain the fine line between either applying too much or too little, and failing to so may result in the oily surface residue. Still, we have noticed no downsides significant to explain. Let’s see what happens in the coming days.
Best End Grain Sealer - ANCHORSEAL 2 Green
What is an end grain wood sealer? We often receive questions as to why we should use end grain sealer. Actually, it is a combination of one or more waxes with water (known as a wax emulsion), or sometimes a combination of wax and polymers. Whatever the case it mainly seals the end grain of greenwood, or face grain of carvings and turning blanks. The applied areas stop getting dried, and the wood, mainly fresh-cut logs and lumbers piled up outdoors, stay green and live.
However, not all but the best end grain sealers like AnchorSeal 2 can successfully keep woods as it is for a long time by slowing down the drying process. How? Usually, AS2 takes the moisture under control and reduces moisture loss due to both hardwood and softwood's air drying, keeping those protected from checking and splitting. Additionally, it works as a Pentacryl, as there are added Polymers ( We are not convinced if there is Paraffin), which stabilizes the wood and stops shrinking or cracking.
AS2 is industry-leading to protect wood bowls, cookies, turning blanks, and live-edge wood slabs. It is also the best-in-category for protecting and stabilizing deck end cuts for the exotic (tropical) hardwood species up to 90%, as far as observed. All will be free from sap-stain and blue-stain caused by fungi. It is a water-based non-toxic emulsion available in more than 35 colors and the colorless (clear) version. You will also get it available in winterized formulas.
Not a tough-to-apply agent by any means. Using a brush along with a sprayer or roller is necessary. It may be backed by any engine type - electric, gas, or air operated. But a tip measuring 0.21”/0.55 mm or larger than that is recommended. Generally, a thin or single coat is enough, but for clogs larger than 24-inch/60-cm will need thicker coating or two coats within 15 minutes. While applying to the cut ends of a deck board, use a sponge applicator or a thin brush, and make sure the AS2 wax emulsion does not get on the board face. It is economical and may require approximately 1 gallon for each 100 square feet area.
So far, users are highly satisfied with the grain sealer. No significant downside was reported, and nothing came out in our inspection too. But poor packaging, leaked or improperly sealed containers are the common complaints received from buyers. AnchorSeal authority should concentrate on this.
Best Teak Sealer - Star brite One Coat
Teak is a species of tree belonging to the Tectona genus and Lamiaceae family native to the tropical region. It produces hardwood and has worldwide acclaim, especially for durability and water-resistance. Applying a quality sealer built particularly for teak woods turns the wood to be more glossy, attractive, and natural-looking. So, we figure out the right one for you - Star Brite One Coat Teak Sealer.
It enhances wood endurance and gives a lifeline twice than it has in general by preventing teak from sun, rain, moisture, fungi, and other stains. Teak becoming grey can be prolonged with such a sealer application, and you can remove the old coat or re-apply a new one at any time without causing harm to the wood.
Star Brite One Coat is particularly engineered for teak-made decks on yachts and sailboats that spend their entire life in salty tough environments. Besides being a marine grade sealer with salty water dealing capacity, it simultaneously performs on any other teak made outside structures, including, a pool deck, lounger, patio furniture, or a bar.
The special gel formula prevents spills, splatters, or drips if applied vertically. As the name suggests - one coat is enough to seal teak wood from moisture and water-related damage or rot, leaving a beautiful deck that requires no maintenance. Besides, the polymers prevent everything, including sun, salt, UVs, and fungi. As said, teaks thus stay protected from becoming black or grey. Instead, it contains its natural color.
Star Brite outdoor teak sealer offers super support to your teak decks and structures from fading or decaying, especially in northern climates. Usually, easy to apply, but maintaining a temperature around 50-degree Farhenheit will probably provide the best drying. And, we think applying Star Bite at least 2 or 3 times a year helps to keep the teaks more protected; otherwise, a risk of damage remains!
Best Sanding Sealer - Rust-Oleum Zinsser Bulls Eye Sealcoat
What is a sanding sealer? How does it work regarding wood? Going straight without introduction:- a sanding sealer is the first coat to sand or finish the grain of wood surface (the pores of wood) before applying an adhesive or paint. It is the base for topcoats, and therefore, sometimes, the material used in the topcoat is also used as a sanding sealer subject to certain dilution. They are sometimes called a spit coat because of their thinned application.
Quality sanding sealers are usually available as clear lacquers with the capacity of ensuring a nice undercoat that bonds really well with the finish. A sanding sealer also contains a soapy substance named Zinc Stearate that enables an easier sanding. You can achieve an excellent sanding result, followed by a super finish and attractive topcoat. But you should not apply more than one or two coats to get it ready for sanding.
SealCoat Universal Sanding Sealer is our recommendation for those who really want a base coat that sand all pores shortly, leaving an ultra-finish wood surface to apply the topcoat by the same sealer or paint. It is a solution of entirely wax-free shellac in denatured alcohol.
The patented SealCoat is formulated to be compatible with all clear wood finishes. Spraying or brushing - any method can be applied based on wood type. Dries so quickly after application so that you can sand and recoat within 30 minutes to 1 hour. For softwood like pine, you can use it as a pre-stain conditioner. 1-quart of Rust-Oleum Universal Sanding Sealer is enough to make ready an approximate 400 to 600 square feet to be sanded. It is economical and completely reliable.
How Do Wood Sealers Work?
Like almost all other sealers, wood sealers act by penetrating the wood surfaces to fill the pores there. Immediately after application, the wood surface begins to absorb the sealer while it is still liquid. Through this process, the wood's pores begin to fill, and after a certain time (half an hour to 1 hour), the liquid sealer begins to harden. Within 1 hour of application, the liquid sealer no longer rolls, although the curing takes 24 to 72 hours to complete. Finally, the surface gets a reinforced coat subject to quality penetration and drying. And, the best result depends on wood porosity, sealer quality, and application consistency.
Benefits of Outdoor Wood Sealer
Anything people use is based on the utility of that thing. It means people use it calculating how beneficial or useful it is. Accordingly, wood sealers also have some advantages, which is why their use is increasing. We will highlight the main points, instead of explaining those in detail, as such a briefing is enough to explain the importance and benefits of wood sealers.
- Offers a clear, natural, surface with enhanced grain;
- Leaves a satin finish surface without membrane;
- Gives a surface more capable of bonding of paint, stain, varnish, and adhesive;
- Does not alter or change (in any way) the physical characteristics of wood;
- Seals, waterproofs, and hardens the wood;
- Slows seepage, prevents dampness, and preserves from mold, fungus and warping;
- Keeps the surface non-slippery;
- Application is pretty much easy;
- Super economical;
- Mostly environmentally (except a few).
Types of Wood Sealers (Water-Based, Oil-Based, and Others)
If you are not an expert, it is normal not to know the different types of sealers (depending on their use and application). As a newbie or DIY, it is much more important to understand what a sealer is, not their differences initially. Understanding sealers will help you know their types over time, based on your work variations. However, we will give some fundamental ideas here. And if you want to know more, it is more fruitful to research according to the job for which you will use the sealer. Otherwise, there is a possibility of losing the feed.
So basically, sealers are of two different kinds, based on their formulation (ingredients and producing formula) - (i) water-based sealers, and (ii) oil-based sealers.
By now, the water-based wood sealers are more popular, and there are good reasons behind it. They are almost odorless and non-toxic. Quick-drying is the biggest quality of them, and they provide a relatively hard and stiff coating after curing. But sometimes the wood loses its original appearance a bit. The finish or coating makes the grain underneath less visible, making it look dull and less clear and reducing the surface's attractiveness. However, it is very unlikely to happen as long as you use quality water-based sealers unless you are using an expired item.
However, if you are obsessed with external beauty - I mean, if an attractive outlook is your first preference, choosing an oil-based sealer should be your decision. But of course, buy brand sealers that have already made a name for themselves as reliable. But, if you are an expert, it should not be difficult for you to choose a new sealer with good quality. Anyway, the oil-based sealant makes the wood grain more visible and attractive and offers an excellent luster shine throughout the surface, which even reflects the sunlight.
As we have listed some of those products above, quality oil-based sealers also have other quite effective and reliable features. The biggest mistake buyers make when buying is that they pay attention to an oil-based sealer's shiny look, not to other features. This results in buying cheap quality and harmful, but shiny sealers - the whole surface gets ruined! Don’t do this, and get the quality one from any of the reliable brands.
However, both water-based and oil-based sealers have sub-groups under them, for instance, clear, semi-transparent, shellac, solid, etc., but we will not explain them. As said, it’s better you research according to your requirements. For illustration, you need one for sealing and get your wood prepared for sanding, so research on what is a sanding sealer and which one is the best for it - this way should keep you more focused and prevent from losing the trail being a newbie or DIY.
Best Brands for Wood Stains and Sealers
We have always said that well-known brands always try to maintain their reputation. Their main tool for that is to create quality products and maintain its quality consistently. It's not that ill will or any other benefit never distracts them, but it's much less likely. Therefore, our advice is to choose the desired wood sealer from a reliable brand.
However, which brands should you consider reliable in terms of wood sealer? You should know our product list by now, and the answer lies there because we have listed the best wood sealers from the best brands! Moreover, we have discussed which brand of sealer is most acceptable for a particular purpose and why. Summarizing that again for your convenience:
- Ready Seal - Affordable and available wood sealers and stains;
- Seal-Once Marine - HighTech and long lasting marine wood sealers and stains;
- Thompson’s WaterSeal - Premium quality and expensive multi-purpose wood sealers;
- Olympic Stain - All weather protection wood sealants and stains;
- Rust-Oleum - Sanding wood solutions, sealant and stains;
Things - What to Look for When Buying Wood Sealant
It is always relative, with wood sealer being no exception. A sealer can be particularly useful for a job, or another can have a variety of uses. Again, a sealer may be good, but it may not work in any particular weather. The amount of application (maybe less or more), type of finish and thickness of the coating (that you desire), and many other likely things play roles while deciding the best sealer., and therefore, it isn't easy to choose.
However, we have done that for you and have provided an infallible list from which you can choose the sealer you need without effort. You may be wondering what the most fundamental things to check when selecting the best sealer are! In short, we have some of those hereinbelow.
Purpose and Application
The first step is to proceed with what you will use the wood sealer for. Suppose you want to secure the end grain of a log or lumber. Without considering this primary aspect, searching sealers may help get an excellent sealer, but it will not fulfill your real purpose, and therefore, not the best sealer for you. If you come up with a sanding sealer where you need an end grain sealer, it is just stupidity and wastage of money, which may ruin your whole project. Therefore, starting with your purpose and going with that should be your first step while selecting the best wood sealer.
Additionally, consider the probable intensity of the application. Some need deep penetration, while some want less; some prefer thick one-coat, while some need thin double coats. These application diversities should be counted before buying a wood sealer.
The weather and climate of the area you live should influence your decision to buy a wood sealer since you will apply it in that particular condition. There are some climates where the weather changes very fast, but the magnitude of change is not very terrible, while some climates are extreme always. Quick weather change, or constant extreme climate - whatever, it affects the sealant's chemistry during application. So your location and the weather, especially in the event you reside in an extreme climate zone, should be considered twice and buy the right sealer for it.
Level of Resistance
The wood sealer's resistance is crucial, as the level resistance determines how much and how long the applied wood will stay protected. A sealer has different types of resistance, i.e., against water and moisture, sunlight and UV radiation, mildew, mold, and other fungi. It is not that every sealer can provide all resistance at the same rate, they differ, and that is where you need to apply your rationality judging your requirements.
An illustration may clear it well. Assume you need to build a wooden structure in a damp and shady (less sunlight) area close to a pond. In that case, you should emphasize a sealer that has high resistance against water, moisture, and mildew. If the sealer has less UV-protection mechanism, you should not worry about that! Conversely, when you need to install a wooden object under intense sunlight, the sealer must contain high UV-resistance and others. So, the level of resistance should always be your special concern when choosing a wood sealer.
The health risks of a product must be considered before buying, although we often miss in doing so. Wood sealers can usually cause physical damage in two ways - i) used ingredients, and ii) wrong application.
The second issue is not related to purchase, so you only consider the first fact while buying a sealer, which mainly indicates high Volatile Organic Compounds in a sealer. Fumes are emitted when the sealer is poured or applied. These fumes or sometimes the droplets carry those high VOCs into the human body. It can have many harmful effects, such as throat irritation, cough, or headaches. Long-term consumption of high-VOCs can lead to life-threatening problems like damage to the entire nervous system or kidneys. So, avoid sealers with high volatile compounds.
Color vs Clear
Mostly transparent, but some colored sealants are available that do sealing and staining at the same time. These can be of different colors, and we have included some of them in our list above. So, when you will buy a sealer, keep this thing in mind as you want. Nowadays, however, users prefer the combination of sealer and stain rather than just a sealer.
Coverage, Price, and Durability
Even if you do not put the first two under prime concern, the last one should be critically judged while choosing a sealant. Note the price you are buying it, and the amount of area you are covering accordingly is reasonable! Do not forget to check the possible durability of the sealer. If you buy that at a low price and do additional maintenance 2 or 3 times a year, it only increases both the cost and labor at the end, nothing else. So, please think before you buy it.
