3.2 CLEANING
2. Accurately form intersections and returns. Perform cutting and drilling of tile
without marring visible surfaces. Carefully grind cut edges of tile abutting trim,
finish or built-in items for straight aligned joints. Fit tile closely to electrical
outlets, piping, fixtures and other penetrations, so that plates, collars or covers
overlap tile.
3. Placement Methods:
a. Install tile on floors and masonry walls using Latex-Portland Cement.
b. Install base without wall tile using Latex-Portland Cement.
4. Jointing Pattern: Unless otherwise shown, lay tile in grid pattern. Layout tile
work and center tile fields in both directions in each space or on each wall
area. Adjust to minimize tile cutting. Provide uniform joint widths.
5. Grout: Install in accordance with applicable ANSI standard as specified
herein.
B. Expansion Joints:
1. Install where required per TCNA “EJ171”, where required below, and per
approved layout.
a. Interior locations (at grade): 20’ to 25’ in each direction
b. Install where tile work abuts restraining surfaces such as perimeter walls,
curbs, columns, pipes, changes in backing materials, etc.
c. Install directly over joints in structural floor including construction joints or
cold joints.
2. Joints shall be same width as grout joint, but not less than 1/4”.
3. Set compressible back-up strip when mortar is placed or utilize removable
wood strips to provide space for back-up after mortar has cured.
4. Keep movement joints cavities open and free of dirt, debris, grout, mortar, and
setting materials.
5. Install sealant after tile work and grout are dry. Follow sealant manufacturer's
recommendations.
C. Grout Sealer: Provide one coat of grout sealer to all grout joints using foam rubber
paint brushes. Care shall be taken to avoid excessive drippage and runs onto tile.
A. Upon completion of placement and grouting, clean all tile surfaces so they are free
of foreign matter. Unglazed tile may be cleaned with acid solutions only when
permitted by tile and grout manufacturer's printed instructions, but not sooner than
14 days after installation. Protect metal surfaces, cast iron and vitreous plumbing
