Great question. Many people think that epoxy is a toxic material. The material can be toxic in a liquid state. This is why we suggest always using a professional to install your floors instead of doing it yourself. When epoxy is sanded to get the finish that you want, that dust can also be toxic. When you work with professionals like us, you will not have to deal with either one of these issues. In its hardened state, epoxy is non-toxic and perfectly safe to use around food prep, children, and your animals.
