3C Sealants Wood Repair Resin Primer is a 2-part, solvent-free fluid based on epoxy resin with a mix ratio of 1:1. It has excellent adhesion to wood, stone and concrete and penetrates deep into porous surfaces. It is used as a primer before applying 3C WOOD REPAIR EPOXY RESIN. It reinforces the wood fibre and prevents moisture penetration into the wood. This primer strengthens the fibres of the wood, penetrates quickly and deeply into the wood, and gives a stronger bond of the epoxy repair to the surface.
