If you don’t want your wood deck planks to rot, a deck stain is a preventive solution you should opt for. But as recent studies show, not all stains are safe for humans, plants, and pets.
While it’s best to protect your deck, it’s important to keep your health and safety in check. To help you find the best deck stains that are safe and effective, I’ll share my tried and tested options in this article!
Reviews of the Top Deck Stains
1. Defy Extreme Wood Stain
The Defy Extreme Water-Based Wood Stain is my top choice among available wood stains today. The semi-finished Defy deck stain features various natural wood tones, which will show your deck wood’s natural beauty. This new tone also helps counteract the greenish hue still found on pressure-treated lumber.
A key feature of this product is its composition, which includes ingredients that block harmful UV rays, thus preventing fading. After applying it on various decks, this stain has consistently retained a fresh look even after prolonged sun exposure. Additionally, it is water-resistant.
However, it’s important to note that this stain should not be applied to deck boards made from newly pressure-treated wood. I recommend waiting approximately six months before application. This allows time for the chemicals in the wood to dissipate, ensuring they don’t interfere with the stain’s absorption and effectiveness.
What I Like
- Its large quantity offers more value and coverage per purchase
- The formula is long-lasting compared to counterparts
- It has low VOC content
- The stain is available in multiple finishes
What I Don't Like
- You'll need to wait for six months before applying it on pressure-treated wood
- The brush I've used with this stain needs thorough cleanup
2. SaverSystems Deck Stain, Semi-Transparent
Another one of the best deck stains out there is the SaverSystems Semi-Transparent Stain for Decks, Fences, and Siding. Using this, you can give your deck a new look that looks natural and resistant to fading and staining.
Applying this opaque stain, especially in a light walnut shade, results in a uniformly smooth finish. However, you’ll need to apply two coats to enhance the shine and bring out a brighter color.
Also, it’s water-resistant, perfect for softwoods, cedar decks, and redwood. However, I’d advise waiting for the wood to age for one year at least to let natural oils dissipate to not interfere with the absorption of the stain.
What I Like
- It is formulated with low VOC content
- You can use it on damp wood
- It works as a stain and deck sealer
- It works well with multiple wood tones applications
What I Don't Like
- It's not ideal for hardwoods
- You'll need to apply at least two coats
3. Ready Seal Wood's Sealer and Stain
The Ready Seal Wood Stain and Sealer also proved to be an effective coating that protected wooden decks. It comes in various bright, wood-toned colors, providing deep protection while allowing the natural wood grain to shine. Its formulation includes UV protection, which is essential for preventing the growth of mildew and mold.
However, as an oil-based stain, it does emit fumes, making good ventilation a necessity during application. This might not be a significant issue when applying it to an entire deck, as the open space typically provides adequate air flow. The water-resistant nature of this stain means that its color remains fresh and vibrant, even after exposure to rain or wet conditions.
This product is also ideal for any pressure-treated wood deck. But, it’s best to wait six months after the wood’s construction allow chemicals to evaporate first.
What I Like
- It works as a wood stain and sealer
- It resists UV rays, moisture, mildew, and fading
- You can choose from a variety of finishes and hues
- The finish suits common exterior wood types
What I Don't Like
- It emits fumes
- You'll need good ventilation when applying the product
4. Cabot Semi-Solid Deck Stain
This Cabot Semi-Solid Stain is a great choice for replacing mismatched or distressed wood surfaces. Its oil-based, high-pigment level, and UV protection provide a long-lasting and even-looking exterior wood finish.
When applied, this semi-solid stain transforms wood into a dark, deep color. Unlike other wood stains I’ve tested, this oil-based stain didn’t hide the wood grain; it improved instead. It’s also low in VOCs [1], so it doesn’t emit fumes.
Overall, this wood stain’s rich and dark tone is ideal if you want to restore a deck that needs a boost. Moreover, its versatility allows for upgrading various types of wood surfaces or existing decks, making it a flexible choice for different projects.
What I Like
- It is perfect for heavy-duty re-staining
- The product is available in multiple finishes
- It is corrosion- and fade-resistant
- You'll only need one coat
What I Don't Like
- It can conceal wood grains
- The finish can be too dark for some
5. Seal-Once Premium Marine Wood Sealer
This water-based transparent stain provides elevated protection for any deck restoration. True to its “marine” designation, it excels in safeguarding wooden decks from water damage, making it particularly effective in areas exposed to saltwater.
Compared to other wood stains I’ve tested, this water-based stain minimally alters the wood’s natural appearance. Post-application, it maintains the original tone of the wood, and interestingly, its yellow color does not transfer to the wood surface. Additionally, it does not emit hazardous fumes, promoting a safer and more environmentally friendly use.
So if you want to maintain the natural appearance of your wooden deck while also protecting it from moisture, Seal-Once Marine Premium Wood Sealer comes highly recommended.
What I Like
- It is a very transparent stain
- It contains low VOC
- It works great at wet climates or with frequently weathered deck
- It matches most exterior wood types
What I Don't Like
- The finish can be transparent for some
- You'll need to wait before applying another coat
6. Valspar One-Coat Semi-Transparent Stain Sealer
Valspar’s semi-transparent stain offers effective one-coat protection for wood decks against various damaging elements. This product not only maintains the wood’s aesthetic appeal but also shields it from harsh weather conditions.
Its formulation provides long-lasting defense against UV light, which is crucial in preventing wood rot, cracking, and peeling. Additionally, this stain creates a finish that significantly inhibits the development of mold and mildew on exterior wood decks. Its ease of cleaning is another benefit, though it requires a drying time of over four hours.
What’s unique about the Valspar One-Coat Semi-Transparent Stain Sealer is is it comes with a four-year to six-year guarantee, varying based on the application method.
What I Like
- The single-coat application saves time
- It effectively protects decking against UV rays and weather
- It's suitable for both cold and hot climates.
- It comes with a product guarantee
What I Don't Like
- The drying time can take longer
- The finish is too transparent to be noticed
7. Behr Solid Color Waterproofing Stain and Sealer
The Behr Solid Color Waterproofing Stain and Sealer can hide various imperfections and make your old wood deck look new. Plus, it works great on composite decking, too.
The all-in-one solution from Behr includes a sealer and solid stain, transforming the look of your old wood decks or even a new deck. It’s 100% acrylic construction provides unmatched protection against rain, snow, and UV rays. Two coats of this solid color stain can last up to 25 years if used on siding or fences.

Deck Stain Buyer's Guide
Oil-Based vs. Water-based Stains
Compared to an oil-based stain, a water-based option has better resistance to UV light, which means it can last longer.
A water-based stain is also more eco-friendly, fast-drying, odor-free, and prevents moisture from getting trapped in the wood. But the drawback is they can take longer to apply.
In comparison, oil-based stains are easy to apply. But they typically will only last for a while. These tend to trap moisture and have less lasting power.
If you’re already using an oil-based stain on your deck, you should use another one instead. And if you’re planning on using a water-based one, it will likely peel off after a while.
This is because the water-based stain has a lower density than the oil-based one. If you decide to switch to a different type of stain, you’ll have to sand the entire deck.
But due to the existence of volatile organic compounds in oil-based products, some regions do not allow the use of these products. Take note that California is one of the most rigid in the country when it comes to standards for the use of oil-based stains.
If you live in this particular area, you might find it hard to purchase oil-based stains near you.
Level of Transparency
The level of transparency to which wood stains can be opaque or transparent determines the deck’s finished appearance and how well they can protect it. Four different opacities can be used for deck stains:
Toner
This is a close relative to a clear sealer. It only adds a slight color to the wood, which won’t change its overall appearance. I recommend applying this yearly if you want to protect the deck better.
Semi-transparent
Semi-transparent stains are mostly used on decks to add a hint of hue but expect the wood grain to be noticeable still. Also, semi-transparent stains usually offer sealer protection. Recoating must be made every 2 to 3 years to restore a deck properly.
Semi-solid
Semi-solid, also known as semi-opaque, wood deck stain contains enough pigment to conceal most of the grain while enhancing the color. However, it requires recoating every 3 to 4 years.
Solid or Opaque
Solid stains, sometimes referred to as “solid deck stain,” is the most pigment-rich type and can last the longest. However, it requires a recoat every four to five years. Also, the solid stain is the densest, completely hiding the wood fibers.
Color
Aside from being transparent, the best deck stains can come in various colors. Therefore, it is important to consider your deck’s shade before picking the wood stain.
Make sure that the deck stain you choose will highlight your deck’s character and stand out against your house’s overall color. Some of the colors include brown, blue, gray, and red.

Deck's Age and Current Condition
Before you start shopping for exterior stains, it’s important to know the age and the current solid stain condition of your deck. Choosing a more expensive stain will last longer and prevent you from having to apply new ones often.
Although your personal preference may play a role in the type that you choose, the type of wood that was used for the construction of your deck will also affect the opacity and color of the finished product.
For instance, solid and semi-solid stains are better for medium-cost-friendly woods such as cedar and pressure-treated pine.
Wood Type
The different types of wood species and some types of wood are suited to varying weather conditions. While some types of wood require protection to maintain their natural beauty, some can eventually benefit from a deck stain that will bring out colors.
When it comes to building exterior decks, the most used types of wood are as follows:
- Treated: Unlike other types of wood, you can purchase treated wood at a fraction of the cost. It can resist weathering and rot and is ideal for decks treated with alkali copper quaternary (ACQ).
However, it can take up to six months before ACQ completely dissipates from the wood. When staining a treated deck, wait until six months after the installation to apply a deck stain.
- Teak: Teak is a hardwood that contains natural oils protecting it from decay, water damage, and fungus. It can withstand harsh elements for up to 50 years, and you can refresh it with light sanding.
Although it can look attractive over time, applying a wood or deck stain is not necessary to maintain its appearance.
- Cedar: Cedar is a natural wood that's resistant to rot, deterioration, and insect damage, making it an ideal choice for decks. However, it's also expensive.
When it's in good shape and new, it doesn't need a stain, so long as it's regularly applied with a penetrating sealer. If an older cedar deck shows a weathered gray color, it can be as it is, or apply you can apply a tint to restore a deck.
- Redwood: Redwood is an expensive wood type for decks, but it's reliable as it can resist moisture damage, insects, and decay. It also has natural oils giving it a warm reddish-brown color.
To maintain its natural beauty, I'd advise against using deck stains on a regular basis and apply a clear penetrating sealer. Older redwood decks can benefit from a combination of a wood stain and sealer.
Temperature
High temperatures or cold weather can affect the curing time of deck stains. The temp range should be between 40 to 90 degrees F, but don’t forget the humid level. When the humid level is low, the faster the deck stains cure and dry.
Type of Application
Depending on the type of deck stain, you can paint your deck using a variety of tools: roller, brush, or sprayer. Before you start working on your deck, make sure that it is thoroughly cleaned and that any repairs are made.
Additionally, ensure the wood is completely dry, and the temperature is mild. Although deck stains can do well in certain weather conditions, they will not work well in humid or too cold temperatures.
Dry Time and Cure Time
Before you start working on your newly-built deck, make sure to read the label of deck stains clearly and see the recommended drying time.
This means that if a deck is not ready to be walked on, it might not have the full color of the wood. Also, if a deck is not fully cured, it might not have the full effect of the stain.
Water Resistance and UV Protection
Water-resistant wood stains, such as oil-based and water-based stains, can prevent water from soaking up the wood. This can help prevent rot, swelling, and damage to the wood. The best stains also repels ultraviolet damage, which can lead to fading and splintering.
Actually, some types of deck stains contain mildewcide, which can prevent the development of black mold and white mildew that can lead to wood decay. This added protection usually adds to the cost, but they are worth as long as they can protect wood from harsh elements.
Value for Money
The popular saying “you get what you pay for” applies when it comes to choosing a good quality sealant and stain for your deck. The long-term protection that a good quality stain provides is typically around two to three years.
Less expensive options usually need to be re-applied yearly. Having a deck is a notable investment in your home, and it’s worth the extra effort to protect it.
Deck Stain vs. Sealer vs. Paint
Sealers (whether semi-transparent or not) allow you to enjoy the natural grain and color of your wood while protecting it from rot and water damage. They also repel water and keep it from getting damaged.
Also, some coating types provide a hard surface that can add a scratch-resistance effect to your wood.
On the other hand, deck stains are a type of sealer that adds a pigment to your wood and protect it from UV radiation. It can also provide a vibrant and natural look, but it will eventually fade and crack over time.
Most deck stains need to be re-applied for at least two to five years. Solid and darker colors have the longest-lasting effects.
Meanwhile, deck paint is different from stains or sealers. A deck paint will cover the entire wood surface, allowing you to make many different color choices, while a deck stain will give the wood a natural look.
Why Should You Stain Your Deck?
Wooden decks need maintenance to help keep their longevity and appearance. It’s vital to keep in mind that your deck is exposed to various types of weather, such as rain, snow, and ice. To minimize the impact of these elements on the wood, it’s a good idea to restrain it.
Although it’s important to keep a well-maintained wooden deck, you must consider taking the necessary steps to ensure that it’s protected and looks its best. Some of the most typical reasons why people choose to stain their deck are to protect it and give it a new look.
Here are the top reasons why you should stain your deck:
To avoid cracking: Many people mistakenly believe that applying deck sealant will solve all of their wood problems. However, cracking is not one of the problems that can be solved with just a sealant.
Between the natural drying process and the sun’s ultraviolet rays, wood can become cracked. To prevent this, use an oil-based stain to keep the wood’s moisture content in check.
To repel moisture: Like the exterior paint of your home’s walls, a deck stain can help prevent water from soaking into the wood. Unlike paint, which only covers the surface of the wood, deck stain acts as an impermeable barrier between the water and the wood.
If the water-soaked wood begins to grow mold or mildew, it can eventually lead to the replacement of the planks.
To prevent sun damage: Untreated or unsealed wood can get damaged by the sun. Its appearance changes, its shape can warp, and it can get more prone to cracking.
To avoid decay: This is a common reason homeowners stain their decks. One of the benefits of using a deck stain is to prevent wood from decaying due to harsh conditions. So, it’s worth giving your deck a new coat of stain.
To give a fresh/different look: This is usually the main reason why homeowners stain their decks. So, why should you, right? A previously stained deck can transform into a fresh, lively one by giving it a new coat of stain or seal. It does improve your deck’s appearance while protecting it from harsh elements.
How Often to Stain Your Deck?
Your deck stains’ opacity determines the finished look and impacts how well the product will safeguard your deck.
The most used opacity level, semi-transparent, can add a layer of color to your deck but expect a noticeable wood grain still. As mentioned above, this type usually comes with deck sealer protection, but staining or recoating must be done every 2 to 3 years.
Temperature Range When Applying Deck Stains
If you’re planning on staining a deck, make sure that it’s not too cold or hot. According to most manufacturers, a range of around 50 to 80 degrees F is ideal. But some companies claim you can stain a deck even when the temperature reaches 90 degrees.
If you have a chance to stain your deck without rain in the next couple of days, consider doing so when the humidity is low, and the air is not too humid. In some cases, you can let the stain cure for 72 hours for best results, even if the label says that it can be cured in four or five hours.
You should know that timing is very important when it comes to staining a deck, as some products on the market have longer drying periods. Unlike paint, which can be applied to the surface once it has dried, deck stains need to cure before they can be opened or set foot on.
That’s why I advise homeowners in areas with high humidity and frequent rain to pick a stain that promises a fast curing time. So, make sure to check the stain’s label for clear instructions or refer to deck stain reviews online for added tips.
FAQ
Which deck stain lasts the longest?
The deck stain that lasts the longest is an oil-based deck stain. But it still depends on the type of wood your deck has, how long your deck has been unprotected, and the weather condition.
What is the best stain color for a deck?
The best stain color for a deck is the hues close to cedar and redwood. But other wood tones are also popular these days.
How many coats of stain should you put on a deck?
You should put on two coats of stain on your deck. While some deck stains only require a single coating, adding another coating can add more brightness to the wood.
However, apply as much as the wood can absorb. Hardwoods with extremely dense structures can only absorb one coat of stain.
Why does my deck stain peel every year?
Your deck stain peels every year for two main reasons: poor adhesion and overapplication. With semi-finished products, such as those with a semi-transparent finish, you only want to apply as much as the wood can absorb.
