But since WEST SYSTEM Epoxy is very strong and an excellent adhesive, it strengthens the wood and makes it waterproof.
Will epoxy set in cold weather?
Some resin/hardener combinations are formulated to cure in temperatures as low as 35°F. However, simply using a hardener that cures in colder temperatures does not guarantee dependable bonds. Epoxy can be used at cold temperatures but must be handled and applied with techniques adapted to cold temperatures.
What color is West System epoxy?
WEST SYSTEM pigments are available in three colors, white, black and gray. We suspend the pigments in an epoxy resin base which allows them to blend thoroughly into the epoxy to make very uniform colors. Because the pigment has an epoxy resin base, it is important not to add more than the recommended amount.

Why did my epoxy pour crack?
So, what exactly causes epoxy to crack? The most common reason is the epoxy got too hot while curing, causing it to cure faster and unevenly. The changes and differences in tempurature throughout the pour caused expanding and shrinking, which in turn cracked the already cured areas.

While WEST SYSTEM® epoxy has a long shelf life, age will eventually affect its handling characteristics and cured strength. Although the cured strength of older epoxy may be adequate for most projects, it’s a good idea to use epoxy that less than a couple years old on critical structural joints.
