105 Epoxy Resin Facts

YELLOW GLUE VS EPOXY

When should you use yellow glue (also called wood glue or carpenter’s glue) and when should you use WEST SYSTEM® Epoxy? This is common question epoxy users ask, especially when trying to choose the best adhesive for their woodworking projects. Let’s look at when one is a better choice than the other, and why.

SPRAYING EPOXY - DON'T!

Some people want to know how to thin epoxy so it comes out of a spray gun better while others want to know what Personal Protective Equipment (PPE) is required for spraying epoxy safely. We give them all the same answer: Don’t do it! In short, epoxy is extremely hazardous when sprayed.
