To choose the best epoxy wood filler, consumers should purchase a wood consolidant and a separate shaping compound that can be molded to match the surrounding repair site. This material can be used to repair cracked and damaged wooden fixtures throughout the home. Similar chemicals are available in many home repair stores that claim similar results at a lower price through the use of different chemical agents. These products, which are not epoxy based, tend to become distressed and flake over time, and must be replaced periodically. Epoxy based fillers can bond with the existing wood surfaces and improve the overall condition of the repair, and do not need frequent maintenance.
To create a long lasting repair, consumers may wish to use an epoxy wood filler that is available as two separate compounds and labeled specifically for use with wood. When combined together, these chemicals begin a chain reaction that hardens the substance permanently. These two types of epoxy may be sold together, or as separate products.
The first chemical is available in liquid form and is known as a consolidant. It can be applied to the existing wood structure where cracks or holes may exist. The liquid soaks deep into the wooden surface, penetrating through the grain. This will harden the repair area so that, when the second chemical is applied, additional wood splinters do not chip away or become dented. This type of epoxy wood filler tends to be longer lasting than epoxy paint, which only creates a barrier across the surface of the damaged area that can be in danger of chipping and warping over time.
High quality consolidant will improve the overall condition of the wood. This chemical is different from products that are labeled as wood hardeners. Epoxy based wood consolidant not only hardens the wood, but makes it more durable than the original structure so that it can be cut or sanded as needed. It is also water resistant, preventing future rot and damage from occurring at the repair site. Boating supply stores are an excellent source for this type of compound as it is commonly used in the repair of wooden boats.
The second chemical is a patching compound, available in a putty-type form. This type of epoxy wood filler should be applied with a putty knife or wooden spatula. Its doughy consistency allows it to be pressed into the damaged areas easily, penetrating into the surrounding wood fibers. It then forms a rock-like surface when cured that may be sanded or cut into any shape or texture to better match the surrounding woodwork.
