FRP adhesive is the glue that bonds Fiberglass Reinforced Plastic (FRP) panels to a substrate. It’s designed to handle the unique expansion, flexibility, and moisture-resistant needs of FRP.

FRP adhesive is a specialized construction adhesive formulated to bond FRP panels to surfaces like:

• Drywall

• Plywood

• Cement board

• Concrete

• Plaster

It’s much stronger than regular construction glue and is made to prevent bubbling, warping, and delamination.

Types of FRP adhesives

1. Water-Based Mastic (Most Common)

• Thick, trowel-applied adhesive

• Best for porous surfaces (drywall, plywood, OSB)

• Low odor, easy cleanup

• Not ideal for non-porous or cold environments

2. Solvent-Based FRP Adhesive

• Stronger bond

• Works on non-porous surfaces

• Better performance in humidity

• Requires good ventilation

3. Two-Part Epoxy Adhesive

• Extremely durable

• Used in industrial or commercial installs

• Bonds to almost anything

• More expensive & very permanent

Key Benefits

• Strong, long-lasting bond

• Moisture and mildew resistant

• Prevents bubbling and panel movement

• Works with FRP’s natural flexibility

• Adheres to many substrate types
