Safety Precautions

Well-ventilated area, gloves.

Preparation

The temperature of the adhesive, the surfaces and the working area must be above 50°F (10°C). Walls must be dry and free of dirt, waxes and soap or other residues. Remove all paint, wallpaper, or any loose materials. Unpainted, waterproof drywall is the best backing for tub and shower units. Concrete walls must be well cured, dry and free of any release agents. Lay panels flat and allow them to come to room temperature (65°F to 75°F) for at least 24 hours before installing. Do not use bent or bowed panels. Make sure that corners are 90° from top to bottom. Pre-fit all materials. Use the cardboard box that the tub kit came in as the template. Measure the spout and faucet placement onto the cardboard template and make the cut-outs. Position the cardboard in place on the wall and check for the correct cut-out placement. Transfer the markings on the tub panel. Make all the cuts in the tub panel using a hole saw bit in an electric drill. Drill a small starter hole. Make all the cuts from the face or front panel surface to the rear or backing surface. This will prevent chipping. Set each tub panel in place in the order suggested by the manufacturer. Limit stressing the tub unit into place, as this will weaken the material. Use masking tape to temporarily support the tub panels in place. Make sure the tops of all panels are leveled and all the pieces are aligned. Using a pencil, outline the tub panels in their correct position before gluing. Place the PL Tub Surround Adhesive in a caulking gun and cut the nozzle at a 45° to desired bead size. Puncture inner seal.

Application

Apply the adhesive in a continuous bead starting 1'' (2.5 cm) in from the edge and continuing every 6'' (15 cm) across the panel. Press the tub panel firmly to the wall within 10 minutes of applying the adhesive. Apply firm pressure across the entire panel surface to ensure good contact with adhesive. Some applications will require bracing to maintain contact while curing. For best results, support the edges with masking tape. After 20 minutes hand press over all the areas of installation again to ensure good contact. Connect seams of panels according to tub surround manufacture instructions. Seal the edges with caulking 24 hours after installation. When installing plumbing fixtures, do not allow plumber's putty to be used where it may touch the polystyrene tub surround material as it may cause damage. Allow 24 hour cure time before using the area.

Cleanup

Clean tools and any uncured adhesive residue with warm soap and water. Cured adhesive may be carefully cut away with a sharp-edged tool.
