If you want to achieve a coloured finish and change the hue of the wood, a wood paint, wood stain or wood oil is your best option. While these products are primarily designed to change the aesthetic of the timber, they will offer some level of waterproof protection to any outdoor wood.
Two or more coats of exterior paint are already sufficient outdoor protection. As long as the paint and underlying wood are in good condition, the paint can remain as-is. The best sealer for wood painted in exterior-grade paint is another layer or two of exterior-grade paint. No clear coatings are necessary.
Use high-quality stain, primer, and paint on all exposed wood surfaces to create a protective barrier against moisture. Seal cuts, joints, and end grains, and even the back sides of boards where water can get in and cause damage.
There are two basic product categories for waterproofing: stains and sealants. Stains are used on wood to enhance color and make them weather resistant. Sealants protect concrete and wood from moisture but do not stop water movement through the concrete from the outside. For masonry, the sealants are the go-to product.
Moisture can easily cause rotting and splitting in wood, and a new coat of paint will not do anything to fix the problem. When water soaks into the wood, it can cause wood to expand and swell as well as deteriorate to the point of falling apart. So, painting over the problem only won't fix it, it will just add to it.
These treatments include wood paints, wood stains, wood oils, wood waterproofer & wood sealers, which all vary in a number of ways. Wood paint – an opaque coloured finish that completely covers the grain of the wood with a uniform finish. Available in matt, satin & gloss finishes.
Below is the average lifespan of exterior paint by surface: Wood: Hardwood is more durable than softwood, which allows the paint to last longer on hardwood surfaces. Paint on wood tends to last anywhere from 3-7 years.
Adding wood oil or a layer of outdoor paint is a cost effective method to protect wood from the elements. Note that while both of these methods are cost effective, they will require more frequent application as compared to applying a high-quality wood sealer every three years or so.
Sealant is the best option if you are looking to permanently waterproof wood surfaces. You will need to completely saturate the wood with the sealant and build up the product until it forms a hard shell.
The best way to prevent rot is with proper ventilation. Condensation can gather around windows and cause rot when droplets pool and sit on the wood for a long time. Regularly open windows when cooking or use a dehumidifier to help improve air circulation and reduce condensation.

You can waterproof most types of paint by coating them with clear polyurethane or acrylic. This method can be as effective as spraying a sealant, but may change the paint's appearance by adding a glossy or shiny finish.
1. Apply a coat of polyurethane, varnish, or lacquer to protect the wood from penetrating humidity and moisture that can seep into your deck and other outdoor wood furnishings.
Untreated wood, without any protective coating, generally lasts no longer than two years outside. However, certain types of wood, such as cedar, redwood, cypress, and white oak, are more durable and can last for years when exposed to the elements.
Acrylic paint creates a durable, hard finish that's easier to work with, dries faster and produces lower VOCs than oil-based paint. Plus, the flexible finish resists cracking and adds a water-resistant protection for interior and exterior wood surfaces.
With proper upkeep and maintenance, you can extend your furniture's lifespan for years beyond what wood could handle on its own. Another benefit is that polyurethane keeps moisture away from wooden surfaces to prevent rot.
Teak, cedar, redwood, cypress, mahogany, and ipe are all excellent choices due to their natural water resistance properties and durability. Each wood species has its unique characteristics and advantages, so it is essential to consider your specific needs and budget when making a selection.
Paints. Of all finishes, paints provide the most protection for wood against ultraviolet degradation and simple erosion. A painted surface retards the penetration of exterior moisture, blocks out damaging ultraviolet rays, and seals into the wood the natural resins and other oils that can otherwise be weathered out.
Is Polyurethane Waterproof? This finish protects your floors, but polyurethane is not waterproof. It will make your floors water-resistant, though — the coating repels water and helps prevent water absorption.
Polyurethane
Polyurethane is a polymer compound that is applied as a protective finish over wood surfaces across multiple applications. This plywood treatment is particularly renowned for its tough, water-resistant properties.
While most homeowners are not master carpenters, it helps to know that there are other options to prevent wood rot such as keeping the area dry with a fresh coat of paint. Otherwise, wood rot can spread if left untreated and affect structural integrity.

Sealers are typically used on porous surfaces, such as concrete or brick, to prevent the topcoat from being absorbed into the surface. They can also be used on surfaces that have been stained or painted previously to prevent the colour from bleeding through the new topcoat.
