Things You'll Need
Instructions
Spray glue on one side of the medium density fiberboard sheet and on the finish surface (the shiny white side) of the acoustic ceiling tile. Do not glue the reverse side of the tile; this will be your building surface. Wait about 30 seconds until the two glued surfaces are tacky.
Align and place the acoustic tile finish side down on the glued surface of the fiberboard sheet. Gently, but firmly, press the two pieces together using flat palms and working from the center to the edges.
Place the assembled board tile side down on a flat, smooth surface. The weight of the fiberboard is enough to hold the two surfaces in contact while the glue cures. After 10 minutes, the building board will be ready to use.
