TILING 09 30 00 Setting / TDS-246

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 and F125A.

Mixing Ratios

Mix 6 qts (5.67 L) clean water per 50 lb (22.68 kg) bag of Large

Format Tile-LFT 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.

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. Thin Set Mortar should not be used to fill

low spots in the flooring. Mortar thickness should be less than 3/4"

when beat in.

Cleaning of equipment

Clean with water before the material dries.

Storage

Store in a cool, dry area.

state and federal code jurisdictions.
