How must fibre-reinforced plastic (FRP) panels be prepared before installation?

• A. They must be cut to dimensions corresponding to the substrate surface.
• B. They must be coated with primer before installation.
• C. They must be installed without any cutting.
• D. They must be reinforced with metal studs.

Answer: (A)

Cutting FRP panels to match the dimensions of the wall surface is essential before installation. When you trim the panels to fit the substrate, edges and corners align cleanly, openings are accounted for, and seams line up neatly. This precise fit lets adhesive or fasteners make full contact across the backing, reduces gaps or distortion, and results in a smooth, professional finish. Installing without cutting would leave ill-fitting edges and gaps around features, making the installation unreliable and unattractive. Priming isn’t a universal prerequisite for all FRP installs, and reinforcing with metal studs isn’t standard practice for this material.
