How to Waterproof Wood – Comprehensive Waterproofing Wood Tutorial

Waterproofing wood has many advantages for all kinds of surfaces. This includes preventing wooden materials from damage by weather, for example, sun, heat, and moisture among others. You can also enhance the beauty of your wooden materials and protect them from wear and tear by providing a waterproof layer. However, when learning how to waterproof wood, it is important to know that this won’t provide complete protection. Waterproofed wood finishes will still need regular maintenance over time. Interested in learning how to waterproof wood? We will explore the topic in detail below.

 

 

Why Should You Waterproof Wood

Waterproofing is a process of putting a very strong preventive layer on the wooden surface to completely stop water from penetrating the wood.  You can do this in areas such as outdoor wooden decks and furniture. There are different types of wood – some types resist water conditions better while others are weaker and not able to fight against moisture. Usually, the wood used in kitchens and bathrooms requires impermeable waterproof materials to completely dismiss any moisture threats.

We recommend treating all external wooden materials to protect them from warp and cracks. This is because the wood has a tendency of absorbing water since it is porous. This will cause the wood to distort, affecting the structures. Sometimes water will remove the color of the wood and molds will grow and multiply. Wood waterproofing will enhance and improve the longevity of wood, making it resistant to insects and molds. It is advisable to take great care of your wood, to keep it attractive for the longest time.

How to Waterproof Wood – Applying the Finish

The first process is properly preparing the wood surface by cleaning and sanding until it is ready for application. Wood oil finish must be applied on a platform that is absolutely clean and free of dust particles. You can make your own mixture by putting together several properties. For example make a mixture of oil (one portion), another portion of turpentine, and a half portion of apple cider vinegar.

This combination will make your surface strong and resistant to a number of weather challenges. When doing the application, use a clean cloth to put the oil on the surface. Make sure you do not leave gaps in between your applications. Avoid putting the waterproof on top of old paint but remove the old paint first before a new application.

You need to use the tools according to their specific areas, for example, use a brush to apply solvent-based solutions and a clean cloth specifically for sealants. We recommend a 24-hour gap for drying, and then sand the surface using medium-grit sandpaper. You can put any number of coats that will suit your expectations.

It is very important to read and understand the manufacturer’s guidelines before using any of the products and materials. There are so many different wood products, for example, pine, cedar, softwood, and oak. Each wood requires certain coats, meaning you must have the right type of tool to meet the requirements.

How to Waterproof Wood for Bathrooms

Wondering how to waterproof wood for bathrooms? This can be a tricky area to work in. When you do the surface preparation here, make sure that the surface is left completely dry. You can put the piece outside in the presence of open-air and sun to allow it to dry. It is highly advised to prepare and work outside on the wood materials required for the bathroom. This is because the outside temperature should be more suitable.  This will also quicken the drying purposes.

Working in confined places with sealants is very dangerous both to the environment and to your health. There is the danger of damaging your lungs, eyes, and skin from overexposure to toxic components and chemicals. You should wear protective equipment, adhere to instructions and allow proper and free circulation of air.
