TotalBoat TableTop Epoxy can be applied to PVC lumber. It should be noted that the bond strength will not be quite as strong as some other materials, and it is extremely important to properly prepare the PVC surface to maximize this bond.
Ensure that all surface contaminants have been removed from the PVC lumber. Sanding the PVC and/or flame treating the surface of the PVC will help allow the epoxy to create the best bond possible.
