TILING 09 30 00 Surface Prep / TDS-107
Bonding to Plywood Surfaces
Plywood floors, including those under resilient flooring, must be
structurally sound and must meet all ANSI A108.01 Part 3.4
requirements. See TCNA F150. For questions about proper subfloor
installation,callCustom®BuildingProducts.
Forametallath,fastenevery6"–8"(15–20cm)withfastenersthat
have a galvanized or corrosion-resistant coating. For a 23/32" (18.2
mm) plywood subfloor with 24" (61 cm) o.c. joists, the metal lath must
beaminimumof2.5lb/yd²(1.13kg/M²).Allplywoodseamsshouldbe
gapped 1/8" (3 mm) and protected by placing a minimum 1.5" (38
mm) bond breaker tape over the gaps.

Bonding to Cutback Adhesive
Adhesive layers must be removed, as they reduce mortar bond
strength to cement surfaces. Use extreme caution; adhesives may
contain asbestos fibers. Do not sand or grind adhesive residue, as
harmful dust may result. Never use adhesive removers or solvents, as
they soften the adhesive and may cause it to penetrate into the
concrete. Adhesive residue must be wet-scraped to the finished
surface of the concrete, leaving only the transparent staining from the
glue. To determine desirable results, do a test bond area before
starting. Refer to the RFCI Pamphlet, Recommended Work Practices
for Removal of Resilient Floor Coverings, for further information.
Priming
PrimeallsurfaceswithLevelQuik®LatexPrimerbeforeapplication.
Expansion Joint placement
Expansion joints and cold joints, as described in ANSI A108.01, should
never be bridged with setting material. They must be brought through
the tile work and filled with an appropriate elastomeric sealant, such
asCustom's®100%Silicone.ContactCustom'sTechnicalServicesfor
the proper treatment of control or saw cut joints. Refer to TCNA
EJ171, F125 & F125A.

application; if a second layer is required, install immediately after the
first layer has set to a walkable hardness. If the first layer has dried
over 12 hours, re-prime before the second application. For installation
on wood subfloors with joists to 24" (61 cm) o.c., apply a 1/2" (13
