Install a solid floor, roof or wall with a sheet of this quality standard spruce plywood. Its light colour and softwood surface work well for interior or exterior projects. Set it up as a lightweight medium in walls, floors and other building jobs. The 5/8-in thick plywood comes in a square 4 ft L x 4 ft W size to cover 16 sq. ft. of area. Its construction uses waterproof glue to help strengthen the wood against humidity and water penetration. Use the interior wall plywood for new construction or renovations throughout a home or business. The convenient 4 ft by 4 ft size offers easier handling for smaller projects and areas. Paint or varnish each sheet after installation for custom builds and added protection against the elements. Produced by AFA Forest Products Inc, the board is made in Canada.
