2.3 INSTALLATION MATERIALS

2.3.1 Adhesive: Product recommended by solid surface material manufacturer.

2.3.2 Sealant for Countertops: Product recommended by solid surface material manufacturer.

PART 3 - EXECUTION

3.1 EXAMINATION

3.1.1 Examine substrates to receive solid surface material countertops and conditions under which countertops will be installed, with Installer present, for compliance with requirements for installation tolerances and other conditions affecting performance of countertops.

3.1.2 Proceed with installation only after unsatisfactory conditions have been corrected.

3.2 INSTALLATION

3.2.1 Install countertops level to a tolerance of 1/8 inch in 8 feet, 1/4 inch maximum. Do not exceed

1/64-inch difference between planes of adjacent units.

3.2.2 Fasten countertops by screwing through corner blocks of base units into underside of countertop. Predrill holes for screws as recommended by manufacturer. Align adjacent surfaces and, using adhesive in color to match countertop, form seams to comply with manufacturer's written instructions. Carefully dress joints smooth, remove surface scratches, and clean entire surface.

3.2.3 Fasten subtops to cabinets by screwing through subtops into cornerblocks of base cabinets.

Shim as needed to align subtops in a level plane.

3.2.4 Secure countertops to subtops with adhesive according to solid surface material manufacturer's written instructions. Align adjacent surfaces and, using adhesive in color to match countertop, BICA 304774 - VC WELCOME 12 36 61.16 - 4 form seams to comply with manufacturer's written instructions. Carefully dress joints smooth, remove surface scratches, and clean entire surface.

3.2.5 Complete cutouts not finished in shop. Mask areas of countertops adjacent to cutouts to prevent damage while cutting. Make cutouts to accurately fit items to be installed, and at right angles to finished surfaces unless beveling is required for clearance. Ease edges slightly to prevent snipping.
