Epoxy Resin for Wood
Epoxy resin or resin is a two-component material which cures within a few hours of the components being mixed together then can be cut, grinded, and polished. In contrast to polyester and polyurethane resins, resin epoxy shrinks considerably less during curing. All other products could come off of wood in a few hours or days and as a result are not appropriate to use. There are products for different areas of application, and it is important to choose the correct product. Epoxy resin is suitable for sealing wood as well as waterproofing it.
Polyester Resin for Cracks and Holes

It is important to note that polyester resins contain styrene that could dissolve polystyrene material and polypropylene.
Fiberglass mats are essential when repairing (large) holes. Fibreglass can come in the form of chopped strand mat, surface tissue and woven roving fabric. Fiberglass matts serve as reinforcing material. If you are using fibreglass mat with epoxy, make sure it is powder bound, there is no constraint using polyester or epoxy for other reinforcement materials. Always ensure that the correct amount of resin is applied to the fiberglass mat roll.
