FRP panels before installation should be prepared by cutting to dimensions corresponding to the substrate surface.

• A. True.
• B. False.
• C. Not specified.
• D. Not always required.

Answer: (A)

Sizing FRP panels to the exact dimensions of the substrate surface before installation ensures a precise, secure fit. When the panels are cut to match the wall outline, the back has full contact with the substrate, which promotes even adhesive coverage and a strong bond along the entire panel. This also makes edge and corner trimming straightforward and helps keep joints tight and visually clean. Planning cuts to the substrate dimensions minimizes on-site adjustments, reduces waste, and prevents gaps or edge damage that could compromise moisture resistance or appearance. If openings or irregular features exist, you can mark and cut accordingly so the panel fits neatly around them, maintaining a uniform, professional finish.
