Step 5: Adhesive Application & Panel Installation
A: Woodgrains, Bricks & Stones, Designer & PegPanels: Use high quality cartridge adhesive suitable for wall paneling, be it “Solvent-Based” or “Low-VOC” (contains water).
For solid walls – extrude a bead no larger than 1/4″ diameter around the perimeter of the panel and in 12″ vertical lines.
B: For studs or furring strips, extrude bead of adhesive directly to studs/furring strips.
Push panel to wall and pull back to flash. Follow required flash times on cartridge. Follow manufacturer’s recommended safety instructions.
C: Additional Support: For best results use panel nails in addition to adhesive to secure woodgrain, brick and stone panels. For PegPanels, use adhesive combined with drywall screws for added strength.
D: AquaTile and Panelboard: Use high quality solvent-based or Low-VOC (contains water) trowel-grade tileboard or construction adhesive. Can use 6-7 tubes of 10.5 oz. cartridge adhesive per panel, if gallon trowel-grade is not available, but once extruded onto panel, must still be troweled out with appropriate notched trowel.
Follow manufacturer’s recommended safety instructions. Do not nail AquaTiles or PanelBoards.
Solvent-based adhesive application: Use a 3/16″ V-notched trowel held at a 45° angle, and thoroughly cover panel back with adhesive. Wait 5-10 minutes to allow adhesive to flash off (but remain tacky), then firmly press panel to wall.
Low-VOC adhesives (water-based) application: Use 1/8″ V-notched trowel at 45° angle, and thoroughly cover panel back, out to edges, with adhesive. Wait 10 minutes for adhesive to flash off (but remain tacky), then firmly press to wall. Re-press panel every 15 minutes for the next hour, especially edges.
E: Wait 24 hours before caulking: Use only 100% silicone sealant (not siliconized acrylics) to thoroughly caulk all seams, edges around panels, around and behind all fixtures, and in between seams. For even caulking, apply low-tack removable masking tape on either side of joint. Caulk one joint at a time, and smooth with plastic spoon or fingertip while wearing protective rubber glove. Immediately remove tape after caulk joint is complete. Do not wait for caulk to cure.
Mouldings: PanelBoard joints can be caulked, or trimmed with extruded plastic mouldings. If using mouldings, squeeze a small bead of silicone caulk into moulding channel before inserting panel.
