Buying Guide – The things You should Consider

best epoxy for filling voids in wood

If you want to buy a good quality epoxy then you should consider the following. Let’s have a look.

#1  Epoxy filling material for wood

Most of us know that epoxy is a very strong and durable resin. So before choosing an epoxy, ensure that the one you are about to choose can be used on wood as well. Few epoxies do not work on wood because they do not get mixed properly with the wood fibers.

#2  Quality of epoxy resin

The quality may vary from one brand to the other. So you should choose the best epoxy that is readily available in the market. The best epoxies for wood are normally the ones with a high level of resin solids, along with other resins like Dicyandiamide.

#3  Epoxy color

The best epoxies for wood are normally the ones that are clear in color and are not grainy. Though there are epoxies for wood in the form of chipboard as well that come with a color, they are not suited for use in excess. So buy a good and clear epoxy resin that can be easily mixed with the wood fibers.

#4  Hardener of epoxy resin

The best epoxies for wood normally come with a hardener like MEKP that is very effective in curing the epoxy resin. So before finalizing the epoxy material, make sure it has a hardener that will not prove harmful to the wood fibers.

#5  The cost

It is obvious that the best epoxy for wood is not a cheap material. So before finalizing the product, make sure you choose a product that is cost effective as well.

Final word

Epoxy is the best way to fill those pesky gaps and cracks. It’s strong, durable, and water resistant. You can use it on any type of wood surface – even if it’s already been painted or stained. There are so many different colors available, you can match the color of your project perfectly. So, I hope you have already got a epoxy from my list.
