How to Waterproof Wood? – Different Methods

The rain, moisture, and different weather factors can damage your exterior wooden surfaces in no time. So, sealing and hence protecting them is a necessity. You’ve already checked out the best waterproof finishes for wood. Now, you need to know how you’ll apply the finish. And it depends mostly on wood surface quality, indoor or outdoor factors, and your purpose with it.

How to Waterproof Wood?

Using the sealant

When using a waterproof sealant, make sure to follow the instructions we are about to break down to you-

1. The first and foremost task is to prepare the surface well. It means sanding, cleaning off the dust, getting rid of any pre-existing finish, wiping off the mess, making it ready for the sealant.

2. Now, the sealant or varnish is a solvent-based product. So, what do we use to apply it? It’s best done with a brush, or maybe a sprayer could work for some.

3. Now, for the wood type, if it’s soft, you’ll probably need 3-4 coats for protection, and for harder ones, a single coat is all you need.

Professional tips:

  • Before starting your DIY, make sure to check the instructions given along the sealant.
  • You don’t have to worry if you drop some extra sealant on the wood; the wooden surface will absorb it.
  • The sealant will only be effective if you apply it to bare wood. So don’t neglect the prep work.

Using wood oil

The procedure is somewhat the same. Let’s brief it down for you-

1. Before we get into the action, you need to make the mixture first. Although it’s not mandatory in the book, the mixture has always helped increase the durability content. Take your wood oil, then the same amount of Turpin, and half the amount of vinegar. Mix it well so that you don’t get bubbles on the surface.

2. Now, for the preparation, take your sanding paper. An 80-100 grit sandpaper will do. The sanding allows to remove any existing paint or finish.

3. Remove the surface dust and dirt well.

4. Next stop is the application. Take a clean and soft cloth. Pour the oil on it and wipe the wooden surfaces with the oil.

5. This time, don’t forget to clean or remove the extra oil.

6. Give it ample time for about a day to dry completely.

7. Once it has dried, finely sand the surface again. Voila! You have a smooth, glossy, and even wood surface allowing long-lasting protection.

Professional tips:

  • Do not apply oil to sealed, stained, or wet wood.
  • Don’t try applying the oil with brushes.

Waterproofing Wood – Different Purposes

Waterproofing Paint for Wood

Bathroom wood

Bathrooms are the ultimate wet zones with high moisture content. So, you need to be extra careful when waterproofing wood surfaces in the bathroom. The procedure will be the same as I dictated above, but some tips and tricks might help you out here-

  • The wooden surfaces need to be 100% dry and clean before waterproofing. So, make sure to allow enough air circulation into the bathroom before you apply the sealant.
  • Remember to dry up the surfaces totally before you get your hands in a mess.
  • It would be best if you can bring out the wooden pieces outside, under the sun.
  • Carrying out the procedure at room temperature is a good way to avoid any hassle so that the coating dries evenly.
  • Even after the waterproofing process, allow maximum airflow in the bathroom.
  • Don’t forget your masks and gloves.
  • If necessary, you can cover other areas besides the intended one with paper or sheets.

Outdoor wood

I was more concerned about outdoor exterior wood surfaces than indoor ones. No doubt, the weather has a major contribution here. The sunlight, heat, rain, snow can cause the wooden surfaces to chip, peel, crack, and ultimately damage. To avoid such situations, here are a few tips:

  • Firstly, make sure to make the outdoor structures with resilient and strong wood. I usually go for high-quality hardwoods. If you want a few names, I’d say go for western red cedar, teak—African mahogany, cypress, etc.
  • When applying the the polyurethane finish, make sure you have a clean surrounding so that the dirt doesn’t come on the surface.
  • It’s a wise idea to waterproof the outdoor wood before the rainy season.


Does paint make wood waterproof?

A high-quality paint does resist water on the wood surface. But the best option is to go for a waterproof paint that would seal the wood surface and prevent water into the cracks and wood fibers.

Does tung oil make wood waterproof?

The tung oil is permeable and penetrates deep into the wood fibers giving it a secured, rigid, and waterproof surface.

How long does the waterproof sealant last?

After coating the wooden surfaces with a nice waterproof sealant, it usually lasts for about 2-3 years. After that, however, it depends a lot on the prep work, environment, and maintenance.

Which one is better for waterproofing, sealant, or wood oil?

Although wood oil has great water-resistant properties, it doesn’t last as long as a sealant that offers a completely waterproof coating.

Final Verdict:

Taking safety measures beforehand for the wellness of your home is what I prefer rather than repairing the damage with double the investments. Of course, wooden material doesn’t go along with water, and we all know it, but that doesn’t mean you have to stop using wood, making your home classy, or spend a thousand bucks a year to maintain it.

All it takes are some good products, knowing the right way for maintenance, some guidelines, and a can of the top waterproof wood finish paint. Don’t let nature take control of the lifespan of your beautiful wooden structures and protect them yourself. What are you thinking? I hope I’ve answered all your questions. Now, pick paint and go for it!
