Paneling & FRP Adhesive

Safety Precautions

Wash hands after use.


For FRP panels: Surface must be free of dirt, oil, loose paint, wallpaper and all foreign substances. Level high spots. Prime patching compounds before applying adhesive. Be sure concrete is well cured and dry. If furring strips are used, apply solid backing before FRP. Lay FRP panels flat and condition area and panels to 50°F or above before installation. Pre-cut and fit panels.

For DPI® 1/8'' Embossed Tileboard & Smooth Panelboard: Condition panels at least 24 hours in installation location. Temperatures should remain above 50°F during conditioning, installation and adhesive cure.


Tools Typically Required:
Recommended trowels

For FRP Panels: 3/16'' x ¼'' notches, V-shaped, flat top, spaced ½'' apart (E6). See photo below:
V-shaped flat top trowel example

For DPI 1.8'' Embossed Tileboard & Smooth Panelboard: 1/8'' (3.2 mm) V-notched trowel. See photo below:
V-notched trowel example

For FRP panels: Using trowel, spread adhesive evenly and uniformly over entire back of panel. Do not leave bare spots. Place panel on substrate within 10 minutes. Press firmly over entire panel, working outward from the center, so that panel is in full contact with the substrate. Follow panel's manufacturer's instructions for use of fasteners and moldings. Leave 1/16'' expansion space at edges. Temporary bracing may be needed until adhesive sets. Full cure in 1-7 days.

For DPI® 1/8'' Embossed Tileboard & Smooth Panelboard: Cut and dry fit panels. Apply adhesive to back to panel using 1/8'' V-notched trowel. Cover entire back of panel then firmly press panel onto wall. Ensure good contact over entire panel surface. Wipe off any adhesive on surface with soap and water. Allow adhesive to dry overnight before caulking. Use 100% silicone sealant to caulk all edges, around fixtures and between panels. Use low-tack painter's tape to joint edges before caulking for a professional appearance. Consult DPI installation instructions for additional details.

Note: Most applications achieve full strength in 12 hours. Applications on low porosity surfaces may take 7 days or longer to achieve full strength. Cure time is dependent on temperature, humidity, porosity of substrate and amount of adhesive applied.


Remove excess adhesive and clean tools with soap and water before adhesive dries. Dried adhesive must be scraped off.
