Specification

TILING 09 30 00 Setting / TDS-119
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

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.
Mixing Ratios
Mix 6 qts (5.68 L) clean water per 50 lb (22.68 kg) bag of mortar.
Mixing Procedures
Mixbyhandorusealow150–200rpmspeed1/2"(13mm)drillto
achieve a smooth, paste-like consistency. Let the mixture slake or
stand5–10minutes;stiragainanduse.Stiroccasionally,butdonot
add more water. When properly mixed, troweled ridges will stand
without slump.
Application of Product
Installation must conform to ANSI A108.5. Use a properly-sized notch
trowel to ensure proper coverage under tiles. Using the flat side of the
trowel, apply a skim coat of mortar to the surface. With the notch side
ofthetrowelheldata45©angle,applyadditionalmortartothe
surface, combing in one direction. Press the tile firmly into place in a
perpendicular motion across ridges, moving back and forth. The
perpendicular motion flattens ridges and closes valleys, allowing
maximum coverage. With some tile, back-buttering is advisable. Adjust
the tile promptly and beat it in with a beating block and rubber mallet.
Mortar can be applied up to 1/4" (6 mm) thick after beat in.
Periodically pull up a tile and check the back to ensure proper adhesive
coverage. If the material has skinned over (not sticky to the touch),
recomb with the notch trowel; if too dry, remove and replace the dry
material with fresh material. Material in the bucket will remain
workable for approximately 4 hours.
Curing of Product
Allow to cure 24 hours before grouting or light traffic, depending upon
temperature and humidity.
Cleaning of equipment
Clean with water before the material dries.
Storage
Store in a cool dry area.
