Covers made of wood will eventually begin to deform and discolor due to rain and sun exposure. A good way to test water and add a longer life to a wooden deck is covering it with fiberglass decking. For fiberglass to bond properly, the cover should be constructed of 5/8 to T 3/4-inch thick / G plywood. Fiberglass many hardwoods will not join because it cannot penetrate it to get a union. The cover should also be the code to support the fiberglass.
Unlike wood, fiberglass decking is smooth and nonporous, making it unsuitable for adhesion of acrylic paint. If you want to paste acrylic, you will have to sand the surface by sanding with 80- and 120-grit sandpaper before applying any primer or paint. Be sure not to overdo it, though.
Some are basic wooden ceilings and flat design. However, sloping ceilings allow moisture and other elements sliding along the surface rather than build. Some wooden ceilings are made of high quality plywood. Fiberglass decking is less complicated to install compared with metal roofing and fiberglass. While fiberglass ceilings seem to be a popular choice for consumers, who are prone to moisture damage over time.
