A Guide To Wood Preserver

Wood, especially when placed in the outdoors, is susceptible to weather and insect damage. It makes it lose its appeal. Besides using decking oil, applying shed paint on your garden shed and investing in good fence paint, use a wood preserver.

Applying a wood preserver on your wooden surfaces will prevent the growth of moulds and algae. It will repel insects and provide a layer of protection against damage by the sun and rain. But you need a quality wood preserver, and we will be happy to guide you through making the best choice.

What You Need To Know

Before buying a wood preservative you need to know that there are preservatives to use on different surfaces. A couple of tips - to make sure you get the right performance on outdoor wood preservatives, it is required to use them where they are intended. A wax or oil based wood preservative is one that formulated with solvents that contain wax or boiled linseed wood oil and mineral spirits to be used mostly on exterior wood.

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

Wood Preserver Buying Guide

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

There are a lot of factors. Some wood preservatives provide a waterproof finish and others 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 wood preservative that doesn’t waterproof the area provides protection from inside like eradicating all types of woodworm, fungi and algae. Sadolin outdoor wood preserver is the perfect evidence.

Clear or colored wood preservative? A clear wood preserver used as a basecoat 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 layer overcoating.

Wood preservatives colours on the other hand, don’t have the same protection as the clear preservatives, on most days. 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.

Something to consider when buying wood preservatives is the cost. In a sense that there are those that come at a very high price and others are cheap. The high-end wood preservatives give great performance and long time lasting effects.

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