Mosaic Backer Boards

Mosaic Backer Boards are cut from 1/2-inch cabinet-grade sanded plywood (either maple or birch based on availability) and are suitable for indoor mosaic projects such as plaques and trivets. The bottoms of the plywood boards are gloss finished to prevent staining, but the edges are unfinished cuts, which can be left as is or painted with a neutral color of acrylic paint, stained with wood stain, etc. The faces of some boards have small splinters missing from the sawing process, but these will be covered by the mosaic.
