SELECTING THE BEST EPOXY FOR WOOD CRACKS
Wood cracks are unique and vary in shape, dimension, color, depth, tributaries, and many other aspects. Therefore, there are several factors that we need to consider when selecting the best epoxy for wood cracks.
1• SCALE OF WOODWORKING PROJECT
The scale of your project will be determined by the size of the wood crack. If the wood cracks involved are long, wide, and numerous then you might have to go with a higher size epoxy resin kit. Also, if the wood cracks involved are deep and not shallow depressions then it is beneficial to go for an epoxy resin for thick pours.
2• AESTHETICS OF WOODWORKING PROJECT
Sometimes you not only want to fill wood cracks to improve the strength and utility of a wood surface but also to improve the beauty of the wooden piece. Therefore, you might want to include color pigments, metallic dyes, or other inclusions. By having such flexibility you can synchronize your current wood crack project with the surrounding theme of things.
To achieve this you need to go for an epoxy resin that is compatible with a wide variety of pigments that allow you to easily include color.
3• FUNCTION OF WOODWORKING PROJECT
The reason you are filling your wood cracks with epoxy is that you want to use the wood piece for a specific purpose on its own or as part of a larger masterpiece. Understanding the specific function will allow you to find the specific epoxy resin for your project.
One, if you are planning to fill the cracks in wood to use the piece for an outdoor design situation, then it is highly recommendable to go for a high UV resistant epoxy resin that can significantly reduce the degree of yellowing. Although yellowing is a complex phenomenon that is caused by various factors, UV is a major contributor, and having an epoxy with specific ingredients to inhibit yellowing is an added advantage.
Two, if you plan on using your piece for food or beverages, then it is critical that you go for epoxy resins which advocate for eco-friendliness and that also guarantee food-safe surfaces during and after application. Your health comes first and it is critical to take a second and ensure that the epoxy resin you select meets this claim and follow the manufacturer instructions to the letter to ensure the best results.
Three, filling cracks is primarily to increase the strength and utility of wood. Therefore, the epoxy that you choose should not only be tough and hard when bonding with wood surfaces but should also be resistant to scratches, impact, and solvents. This way, you can use the wood with filling cracks in a wide variety of uses including kitchen countertops, butcher boards, kids’ floor, and door panels.
4• BONUS FEATURES
Sometimes you are working in wood cracks with corners or on handrails and by having an epoxy resin with the self-leveling capability you are at an advantage of not having to use extra spreaders and additional solvent s to flatten the undulations and waves on the epoxy resin surface.
•LOW SHRINKAGE FACTOR
Epoxy resins shrink after curing. Depending on how much shrinkage there is, you might be required to either pour an overflow initially to cater for any shrinkage or pour consecutive layers — usually one for wood cracks.
You do not want to have the epoxy resin curing significantly below the wood surface such that you need to sand out much of the wood to reach the cured epoxy resin surface. Neither do you want to pour too much epoxy resin to cater for a huge shrinkage factor of your epoxy resin.

All the best in your wood crack filling project!
