CERAMIC TILE: Larger than 4" x 4" tile

THIN SET (sanded): to meet ANSI A 118.4 for latex Portland Cement. All ceramic tile installation must conform to ANSI A108

WECU: WECU Crackless for stress crack suppression only, WECU Soundless for sound control for concrete structure with suspended ceiling: WECU Soundless+ for optimum sound control for concrete and wood joist structure with or without suspended ceiling.

MASTIC: for above grade indoor Installation use a ceramic tile mastic which conforms to ANSI A.136.1 TYPE 1 or a good quality indoor/outdoor carpet adhesive.

1. Subfloor must be structurally sound, level and clean.

2. Spread out mastic on subfloor with flat side of a 3/16- v-notched trowel to achieve good bond. Then, Use the notched side for a good bond to WECU.

3. Install WECU butting seams and up to walls snugly.

4. Roll over WECU with 75-100 Ibs roller starting in the center and rolling to the outer edge to eliminate air bubbles.

5. Cover seams using 1" masking tape. Once WECU is securely adhered to the subfloor proceed with the installation of selected flooring product.

CERAMIC TILE: Set with sanded thin set mixed with minimum acrylic latex solids of 20% to insure strong bond. Be certain to follow manufacturers recommended curing time before using floor.

MARBLE: Install using a medium bed mortar mixed with acrylic latex or use the mud set method.

HARDWOOD FLOORS: Choose floor manufacturer's recommended adhesive for application on WECU. Do not use nails or screws.

6. For Sound Control: Leave a 1/4" gap between perimeter wall and flooring. Insert WECU expansion-joints or fill with acoustical sealant to prevent sound from being transmitted through the walls.
