How To Waterproof Wood?- Learn More Here

Raw or unprotected wood is more likely to rot, warp, or crack. Air moisture, temperature, and some woodworms are responsible for such kind of troublesome. For extending the lifespan of your wood products, consider turning them into waterproof. Treat any daily using exteriorly exposed wood furniture like back patio/porch furniture with waterproofing material. Treating the interior wood furniture or kitchen surfaces with waterproofing materials is also common.

The ways or products for waterproofing are many. Let me highlight three standard and worth mentioning techniques for how to waterproof wood furniture.

​Learn the easy-tackling methods of "how to waterproof wood?”

  • Method 1: Waterproofing with oil
  • Method 2: Use of Sealants
  • Method 3: Use of Stain

Method 1: Waterproofing with oil

Step 1: Choose the oil 

The three oils widely used for waterproofing are Linseed oil, Tung oil, and Walnut oil. Tung oil is usually available in other commercial materials as a mixing component. Raw Tung oil is expensive, so people use it for smaller wood purposes. Walnut is naturally available on the grocery stores and more likely as olive oil. Let me inform you, Walnut oil is out of commercial use due to nut allergies.

As for Linseed oil, they are available on the DIY repair stores though many of them are raw or boiled-one. Now, what’s the difference in boiled Linseed oil?

The boiled-one contains poisonous metal-drying agents. Though it is toxic, people still buy them and use it on the outdoor patio furniture.

Remember, you should never use the boiled linseed oil for anything that involves food.

If you want to buy the raw oil Linseed oil to avoid the metal-drying agents, you can seek the unrefined oil out. This unrefined oil is most likely for use on kitchen wood products and interiors.

Step 2: Purchase your oil.

Find out which part of your wood material you want to treat. The use of exterior stain & deck sealant would be great for larger wooden projects like the patio deck. For the smaller projects like a cutting board, countertop, baseball bat, or table, oil is good enough.

Make a complete list of those want-to-treat surfaces. Trust me; this isn’t a worthless job. This step will eventually help you to know the amount of oil you need to purchase. Choose the best quality as they will stay for years.

After choosing the type of oil according to your need, buy it a little more amount than need.

Step 3: Prepare the mixture.

Now, it time to prepare a more robust mixture of oil by adding apple-cider vinegar and turpentine with the oil. The reason for developing such kind of combination is the preservation of the oil and a durable finish.

As for the proportion, 1 part of the mixture will be turpentine oil, one portion will be Tung oil or Linseed oil or Walnut oil, and ½ part will be apple cider vinegar.

Choose a metal container like a coffee container for the mixing. The mixture should be perfectly blended.

Well, the above step of mixing isn’t mandatory. But, most of the wood enthusiasts make this kind of concoction.

Step 4: Pre-steps of oil application

The preparation of the wood surface is a must because the surface imperfections will be more visible after oil application. Waterproofing mixture is a coating that blocks the moisture resulting in glossy texture. The reason for such a glossy texture is that the oil highlights all the present colors of the wood.

Scrape the wooden imperfections with thick sandpaper to make the wood even. You can also use the metal file as an alternative to sandpaper.

Take fine-grit (220) sandpaper for sanding the whole wood exterior. This step will prepare the wood exterior for oil absorption.

Use a dry cloth for sweeping the treating area or rubbing away the scraps.

Remember to keep the wood dry before oil application.

Step 5: Prepare yourself.

Keep the scrap rags close to you and fold one lint-free cloth. The folding of the rags removes rough edges & ends the potential snags when the oil spreads. Wear gloves of thick rubber while handling turpentine & other mineral spirits containing products.

Step 6: Application of the first coat

Take a little amount of oil on the rug surface. Direct application of the oil isn’t a good idea. Rub the oil mixture using grain by a movement of the interior to the exterior.

Be careful of avoiding contact with the oil during absorbance. The coating should be even. To release the rag absorbed oil, apply new oil droplets instead of rubbing hardly. There shouldn’t be any standing spills of oil.

Step 7: Coat drying step

For oil settlement, you need to wait for 30 minutes. Wipe the wooden surface to remove extra oil and use a dry cloth for the job. Leave the treating zone for drying for 24 hours. The wood may also take more time to dry.

The time for waterproofing using oil is more than the time needs for waterproofing using sealants.

Rub the exterior with “0000” steel wool.

Step 8: Second time of oil application

Apply the second layer of oil onto the wooden exterior. Make the repetition of drying times & the sanding process using the steel wool. You cannot use the wood right after it. The wood needs several days to a few weeks to cure.

If your fingers can smoothly slide across the wooden surface, then the wood is finally cured.

​Method 2: Use of Sealants

Step 1: Preparation of the surface

Remove all the past residue using sandpaper before applying sealants. This step removes all the finished products that hinder the sealants from absorbing. If your targeted wood is previously finished, this sealant method is undoubtedly the best because the oil-based stain doesn’t guarantee you of sinking into the wood exterior.

For the areas that need more attention, use the rougher sandpaper. Then, use a finer one for sanding the whole surface to have an evenly exterior.

Step 2: Go for a water-based wood-sealer

The products are pretty available in any home improvement shop. The common names for the wood sealants are Water Seal & Stain Sealer. The tinted sealant will also do the job.

Note that sealants often have a label on which they wrote the product types on which it can be used. You can see fence sealant, deck sealant, furniture sealant, outdoor sealant, or floor sealant.

Go for a marine wood sealant if your wooden product needs to face humidity, water, and UV rays.

Go through the information on the product, including the application methods and drying times. People use some of these products using a paint sprayer. So, purchase a paintbrush or a paint sprayer for the job.

Step 3: Coating

Apply an even coat using the paint sprayer or brush. Check if the temperature and air humidity are within the range of the product. Otherwise, quick evaporation of the product will take place. You can find the controlled humidity in an area like a garage, so consider working there.

Apply the sealant on a clean surface.

Step 4: Drying

The product’s package must have the direction of drying times, follow it. The time must be comparatively shorter than the times of oil’s drying. Commonly it takes between 4-10 hours.

Step 5: Cleaning the initial coat

For improving the adhesion of the next coating, use fine-grit sandpaper for sanding once the wood is completely dried. NOTE THAT, you will follow this step if only the product instructions recommend it.

For cleaning off the sealants, you can use “0000” steel wool, which is very fine.

Step 6: Applying the 2nd & 3rd coat

The second and third coating is mandatory if the wood is soft because they are cheaper and untreated from the past. While for some hardwoods, once is enough. The hard ones are high in quality and denser in nature.

Some popular softwoods are pine, balsam, cedar, yew, and redwood spruce. Some available hardwoods are beech, hickory, maple, oak, walnut, and mahogany.

Step 7: Time for curing

Give the wood several days for curing before using it. You can see that the water has darkened the wooden surface instead of beading up & flowing off the wood surface if you apply water over wood.

On excellent wood care, follow the application of the sealant every few years.

​Method 3: Use of Stain

Step 1: Choosing a stain that is oil-based & semi-transparent

If your project is on exterior wood, then you will need an exterior-grade stain. For more oil content, the dye needs to be lighter. And these light stains are perfect for the interior woods or the furniture that doesn’t need to expose to the outdoors.

These materials are available in any repair store or hardware store.

Step 2: Preparation of the wooden surface

The preparation of the wood surface is a must because the surface imperfections will be more visible after stain application. Waterproofing mixture is a coating that blocks the moisture resulting in glossy texture. The reason for such composition is that the stain highlights all the present colors of the wood.

Scrape the wooden imperfections with thick sandpaper to make the wood even. You can also use the metal file as an alternative to sandpaper.

Take fine-grit (220) sandpaper for sanding the whole wood exterior. This step will ensure the stain evenly applied.

Use a dry cloth for sweeping the treating area or rubbing away the scraps.

Remember to keep the wood dry before stain application.

Step 3: First Coating

Choose a paintbrush that can evenly apply the stain. Let the surface dry after covering the whole exterior. You need to wait four hours – one day before the second application.

Step 4: Removal of residue

After finishing the drying process, finish sanding the dried exterior using fine-grit sandpaper. For preparing the surface for the second application, wipe it using a tack cloth. Also, make sure that the wooden exterior is dry as well as clean at the same time.

Step 5: Second Coating

Now give the 2nd coating on the dry surface, and it will take comparatively longer to dry. For the best result, provide plenty of hours for the absorption of all the waterproofing oil. After this 2nd application of stain, give a check on stain after a lapse of five hours.

If the wooden surface isn’t sticky to your touch, then the surface is finally cured.

Step 6: Final Coating

Give the final coating of stain on the treating zone following all the same procedures. Though the process needs to be run three times in total, you need to ensure an even surface every time.

Wait for three to seven days for curing the wood before using it.
