Wood Preserver Buying Guide

Before buying a wood preservative you need to know that there are preservatives to use on different surfaces. A wax or oil based wood preservative is used mostly on exterior wood. Water-based wood preservatives are made for use on ground woodwork.


Some wood preservatives provide a waterproof finish and others don’t. A sealer with waterproof properties prevents the wood from rotting and decaying.

Clear Or Coloured

A clear wood preserver used as a basecoat penetrates deep in the wood to highlight the wood grains and protect against UV rays that cause the wood to discolour.

Wood preservatives colours don’t have the same protection as clear preservatives. This, of course, is because they lack properties to repel water and resist fungus growth. They just enhance the natural beauty of the light brown timber during summer. You can either get them in shades of green, light brown and red.
