Sealer For Outdoor Wood Furniture Comparison Table

Education: What You Need to Know Before Buying

We are talking about sealing exterior wood surfaces. So, when shopping for the best sealer for outdoor wood furniture, go for an exterior wood sealer that provides maximum UV protection.

The sun’s ultraviolet rays are one of the primary causes of your paint job cracking, peeling, and flaking away. Some claim that UV radiation degrades the finish at the molecular level, but that’s not the case.

UV rays deteriorate the paint and finish by drying out the resin component. To tell if the sealer will completely waterproof the wood, perform a water drop test.

If the water beads up and rolls away, know that your wooden surface is safe from water or moisture damage. When buying wood sealant, consider your budget, quantity, coverage, application method, and the sealer’s VOC levels.

Other factors to keep in mind include:

Type of Wood Sealer for Outdoor Furniture

Three types of wood sealers exist, namely:

Opaque finish

Opaque Wood Finish is a high-quality, low-maintenance alkyd acrylic wood finish suitable for interior and exterior applications.

It has a satin, nanoporous finish that is water repellent and UV resistant. You can use it on rough sawn and smooth planed wood surfaces.

Semi-transparent stain

Semi-transparent stains add subtle color to the wood’s surface. These wood sealers have the thinnest pigmentation and highlight natural wood grain and character. The type and age of wood determine which wood sealers you use to get superb results.

Clear finishes

A water-based varnish made entirely of acrylic intended to seal, protect, and brighten up wood and other surfaces. It is a non-yellowing formula that contains no hazardous solvents or odors.

Clear finishes offer a long-lasting finish that is resistant to almost all household chemicals when thoroughly dried. You can also opt for latex wood sealers, solid wood stains, or solid stains.

Factors to Consider When Buying the Best Wood Sealer for Outdoor Furniture 

When buying an outdoor wood sealer, keep in mind the following factors:

Project size

To get a suitable sealer for your project, determine how big or small your task is to save money and avoid wastage. For example, if you want to seal a few outdoor chairs, one gallon may be enough. If you are working on a vast deck, three or more gallons based on the wood species. 

Drying time

The time a sealant takes to dry is key to getting exceptional results. It determines how soon you can finish your paint job and move on to something else. Using a fast-drying sealant allows you to apply a topcoat soon and minimize the room for errors. 

UV blockers

Go for a sealer with super UV blockers to protect your surfaces from harmful UV rays. Remember, Uv rays from the sun are one of the primary causes of problems in your outdoor wood as they make the wood warp and split. 


Buy a sealant that can keep moisture away from your outdoor furniture. Water and moisture make the wood rot and decay, necessitating costly replacement.  A sealant’s primary goal is to protect the wood from sun, water, snow, and insect infestation. 

How to Seal Outdoor Furniture

You can use interior wood outside,  but it won’t last forever! To help your masterpiece last for decades, use exterior wood sealers to protect them from elements.

You can use stain sealant combos to cut down the cost and reduce waiting time. Here’s how to seal outdoor wood furniture.

See Also: How to Seal Pine for Outdoor Use

Step 1: Pick A Suitable Finish

Just as a long-sleeved shirt protects against sunburn, several coats of an exterior finish safeguard furniture from intense UV rays and moisture. 

Because paint inhibits UV rays more effectively than clear finishes, applying a high-quality exterior primer followed by an exterior oil-based paint is your best option.

Apply several coats of exterior spar varnish with UV blockers for an organic -wood appearance. Spar varnish creates an established finish that is more durable than oil. 

Step 2: Sand Down The Wooden Surface

Before putting on the sealer, sand the wood surface down to remove existing stains, dirt, and debris. You can use chemical wood strippers to ensure that the sealer adheres well to the surface.

Step 3: Completely Seal the Wood

Leave no part of the wood unfinished. That includes the joints, beneath, and even the legs bottoms. Use a tiny brush or a sprayer to get to the hard-to-reach areas. 

Step 4: Recoat Frequently

To keep your outdoor sealed surfaces looking great, apply a maintenance coat regularly because even the top sealants in the market will wear out with time. It’s cheaper to recoat than to use a new sealant. So recoat your outdoor wood after every two or three years.

What is the Best Protection for Outdoor Wood Furniture?

Although there are several options for protecting outdoor wood, the primary choice for an excellent exterior wood sealer is between water-based and oil-based polyurethane. 

Water-based remedies have a few benefits for wood products.  But For outdoor wood furniture,  the most prudent option is oil. Oil-based formulas protect outdoor wood by preventing water, dirt, and UV rays from destroying wood authenticity.

Second, the oil penetrates deep into the wood, providing maximum protection throughout your wooden structure.

Since protective oil for outdoor wood furniture has a higher viscosity than its water-based counterparts, it dries much slower, resulting in a more uniform finish. 

It is also more resistant to the elements, including extended exposure to UV rays – mainly when tinted. There are numerous factors to consider when purchasing an oil-based exterior wood sealer.

For example, Is it essential to preserve the natural appearance and characteristics of your wood? If this is the case, it makes sense to use an oil-based formula to protect the wood furniture from the elements.

If color and UV protection for wood are more crucial considerations, it would be sensible to select a color tint or opaque protective oil that allows for a bolder natural color choice.

It depends on your preferences since some water-based wood sealants offer unmatched protection from the sun, water, insects and are equally durable. 

It’s a brilliant idea to seal untreated wood with polyurethane sealants and other finishes to give it an upper hand against the elements.

Sealing Outdoor Wood Furniture FAQs

Should I seal my outdoor furniture?

Yes. You should seal your outdoor furniture to protect it from rain, moisture, snow, mold and mildew, and insect infestation. You also seal it to make it more durable. If you leave, it unsealed it will rot, and it’s more expensive to replace it than to seal. 

How to seal an outdoor wood table

First off, get an exterior wood sealant with exceptional UV protection and water-resistant abilities. The sealant should also protect the outdoor wood table from mold and moss growth. That said, here’s how to go about it.

Sand the table using 180- 220 grit sandpaper to remove the existing finish.  Using a  clean, lint-free cloth, wipe off the table and remove the dirt and debris. 

With a high-quality nylon or polyester brush, apply the sealant in the direction of the wood grain. Apply one small part at a time to avoid lap marks.

Wipe off the excess sealant and wait for it to dry before applying another coat. Ensure you seal all table parts, including crooks and corners, to protect them from elements.  

What is the difference between wood stain and wood finish?

A wood stain penetrates the wood deeply,  while a finish forms a protective shield on the outside surface. Some finishes contain colors to highlight or change the color of your wood. Finishes make the wood more durable, so you use them in areas that see a lot of wear and tear. Here are types of wood finishings.

Do you seal or stain the wood first?

The order in which you apply wood stains and sealants depend on what you’re working with at the time.  But generally, we recommend staining first, sealing second, and using topcoat third for the best results. This will ensure the best possible protection for your outdoor wood furniture.

Do I need to seal the wood after staining?

Yes. You should seal the wood after staining it because the wood is still porous, meaning that it’ll absorb water and moisture, which causes it to rot. However, using a standard stain will give the wood some level of protection compared to completely untreated lumber.

How long after staining can I seal?

The majority of wood stains dry entirely in a day or two. Some colors, such as general finishes stains, can take three or four hours to dry. You can then apply the sealer. However, to be on the safe side, wait for three days before sealing.  

Do you sand after staining wood?

Yes. Lightly sand the surface several times with finer grit sandpaper. Remember that you will most likely need to apply several coats of stain to achieve the desired level of protection for your outdoor project. As you apply each coat, be sure to wipe away any excess stain.


When buying the best sealer for outdoor wood furniture, it’s a good idea to stick with wood sealants with an impeccable reputation to avoid making costly mistakes.
