ABSTRACT:
A flexible surface plywood concrete form liner is disclosed which includes a flat planar sheet of relatively thick plywood material which has been precisely sized and squared. The prepared plywood sheet material is coated with a layer of relatively thin, flexible elastomeric material cast as a one-piece layer over the entire surface of one side of the plywood sheet material as well as all four edges. In this way, the elastomeric material is a continuous integral coating bonded directly to the surfaces of the plywood to prevent the penetration of moisture or chemicals from the concrete into the laminations of the plywood during use. A textured negative impression can be provided on the outer surface of the elastomeric material to leave a textured surface in the finished concrete. A novel edge seal which can be slightly angled is formed along the edges of the liner so that the joint between the liners is reinforced to strengthen and prevent blow-out of the concrete at the liner joints.
