Epoxy Dye Bleeding Into Wood. One way is to use a sealant before you apply the resin. Epoxy bleed out is an unintended consequence of mixing epoxy resin with wood.

However, there are several methods for preventing this problem from occurring in your own diy projects so. The result is that the epoxy can seep into the pores of the wood, causing a discolored area or even ruining your project if it’s not handled properly. You can also wait for the resin to cure completely before you sand or finish it.
