Mixing Ratios - powder to water

For installations requiring an ANSI A118.1 mortar, thoroughly mix 6

quarts (5.7 L) clean, cool water and a 50 lb (22.68 kg) bag of

CustomBlend®togethertoasmooth,pastelikeconsistency.For

mortar meeting A118.4 or A118.11 requirements, use 6 quarts (5.7 L)

of Thin-Set Mortar Admix in place of water or 4.5 quarts (4.3 L) of

water and 1.5 quarts (1.4 L) of Thin-Set Admix Concentrate.

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. For large format tile and uneven flooring, use

mortars designed for medium bed applications. Mortar thickness

should be less than 1/4" thick.

Curing of Product

Curing time is affected by ambient and surface temperatures and

humidity. Use the following as a guideline. Allow 24 hours before

grouting or light traffic.

Cleaning of equipment

Clean with water before the material dries.

Storage

Store in a cool, dry area.
