Why Will Fiberglass Resin Not Stick to Wood
There are several reasons fiberglass resin will not stick to wood. One could be the type of wood. Another could be the proportions of the mix as well as the temperature and timing of the setting process.

Wood
Fiberglass resins will not stick to woods that have been treated. They only stick to untreated, clean, dry wood. Redwood is not only usually treated, but it also contains a waxy substance prohibiting adhesion.
Resin
Fiberglass resins, as opposed to plain epoxy resins, have small strands of fiberglass embedded in the resin, hindering the saturation process. For the resin to do its job, it must first penetrate and soak into the wood. The close grain of woods such as oak and cedar prevents that.
Mix
As with all resins, the inability to stick to wood can be caused by the wrong proportion of resin to filling and/or hardener.
Curing
Improper curing of the resin affects its adhesion to wood. This curing is affected by temperature and timing, both of which need to be controlled.
