Smiths Clear Penetrating Epoxy Sealer™ (CPES ™) is a thin epoxy that will penetrate deeply into the surface of wood. CPES Cures premature varnish failure, it will dramatically reduce maintenance costs on exterior wood. It is the ultimate primer for all woods. Furthermore CPES can be used to repair and restore rotten and decayed timber, Fill-It filler can then be used to restore profiles.

CPES 0.95 litre Use and Coverage

Mix 1 to 1 by volume. Coverage varies with porosity of timber but around 5 sq metres / litre on new plywood or softwood.
