Wood Preserver Buying Guide

Before buying a wood preservative you need to know that there are preservatives to use on different surfaces.

Therefore, to ensure you get the right performance on wood preservatives, you need to use them where they are intended. A wax or oil based wood preservative is one that formulated with solvents like boiled linseed oil and mineral spirits to be used mostly on exterior wood.

This type produces odor and it creates an oily finish and either changes the color of the wood or affect Paint-ability. Solvents in an oil based shed treatment are responsible for preventing cracks, swelling and separation at the grains. They are best used on above ground wood like sill plates, sheds and fences. Wickes creocote or Creosote substitute is an example.

Water based preservatives are suspended in water with small amounts of chemicals added to deeply penetrate in the wood. These work from the inside to kill woodworm, fungi, and algae and resist leaching after treatment. They are taylor made for use on ground contact wood. The water-based are safe to use around plants and pets and they do not produce odor. Depending on your project, you can choose between the two.

There are some preservatives that provide a waterproof finish and others that don’t. A sealer with waterproof properties prevent wood from rotting and decaying. Thompsons is a wood preservative brand that produces waterproofing sealers. However, the preservative that doesn’t waterproof the surface provide protection from inside like eradicating woodworm, fungi and algae. Sadolin wood preserver is the perfect example.

Clear or colored wood preservative? A clear wood preserver penetrates deep in the wood to highlight the wood grains and protect against UV rays that causes the wood to discolor. It also has properties that repel water to prevent the wood from rotting and decaying. Clear wood preservers allow for over coating.

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

Another factor to consider when buying wood preservatives is the cost. There are those that come at a very high price and others are cheap. The high-end wood preservatives provide great performance and long lasting effects.

Medium priced are most affordable and they also provide reliable wood preservation. Cheaper preservatives will only serve the purpose for a short time. You will need to treat the wood more often when you buy these.
