MDF plywood is an abbreviation for medium density fiberboard. The material is similar to wood. It is easy to cut, and is used for DIY, construction and woodworking, and has a fine texture on the surface and the wood edge, making it perfect for router cutting. Also suitable for painting and overlaying. Because it is a molded board, the surface is smooth and easy to paint. Medium density and not hard, so it cannot withstand heavy objects. Not suitable for table tops, bookshelf shelves, etc. In addition, there is a weak point that MDF is vulnerable to water. Please apply water resistant varnish, as this may cause mold to grow.
