Fiberglass deck is a type of composite decking that is made of fiberglass reinforced plastic (FRP) and resin. It has many advantages over traditional wood or metal decks, such as high strength, durability, corrosion resistance, fire resistance, low maintenance, and environmental friendliness. However, fiberglass deck also requires proper installation and care to ensure its performance and longevity. Here are some steps and tips for fiberglass deck construction and installation.

The substructure is the foundation of the deck that supports the fiberglass deck boards. It can be made of wood, metal, or concrete, depending on the site conditions and design preferences. The substructure should be level, stable, and free of any defects or damages. It should also have adequate ventilation and drainage to prevent moisture accumulation and rotting. The substructure should be designed according to the manufacturer’s specifications and local building codes.

The fiberglass deck boards are the main components of the deck that provide the surface and appearance. They come in various colors, textures, and sizes, depending on the manufacturer and customer’s choice. The fiberglass deck boards should be cut and drilled according to the layout and design of the deck. The cutting and drilling tools should be sharp and clean to avoid chipping or cracking the fiberglass material. The cut edges should be smoothed with sandpaper or a file to prevent splinters or injuries. The holes should be slightly larger than the fasteners to allow for thermal expansion and contraction.

The fiberglass deck boards are installed on top of the substructure using screws, nails, clips, or other fasteners recommended by the manufacturer. The fasteners should be made of stainless steel or other corrosion-resistant materials to prevent rusting or staining. The fasteners should be driven flush with the surface of the deck boards, but not over-tightened to avoid cracking or warping. The deck boards should be spaced evenly with a gap of about 3 mm to 6 mm between them to allow for drainage and ventilation. The deck boards should also be staggered at the joints to create a more aesthetic and stable pattern.

The fiberglass deck can be finished with various accessories and treatments to enhance its appearance and functionality. For example, the edges of the deck can be covered with fascia boards or trim boards to create a more polished look. The gaps between the deck boards can be filled with caulk or sealant to prevent water infiltration or weed growth. The surface of the deck can be coated with a protective layer of paint, stain, or varnish to add color, gloss, or UV protection. The fiberglass deck can also be decorated with railings, lights, planters, furniture, or other features to suit the customer’s taste and style.
