5. INSTALLATION INSTRUCTIONS
Mixing
For best results, all tiling materials, substrates, room and adhesive should be at
55°-90°F (13-32°C) for 24 hours before and 48 hours after installation.
1Flex
®
Fast Set White: Add 1 gallon of water (3.78 L) to a clean mixing
container. Place drill and paddle mixer in the container and add one 35 lb.
(15.88 kg) bag of mortar. Mixing works best by adding half of bag, mix, then add
additional mortar, mix, etc. Mix material to a thick, creamy consistency. Avoid
breathing dust and contact with eyes and skin. Avoid using high speed mixing (not
to exceed 300 rpm) to prevent entraining air. A small amount of additional water
may be added to achieve proper consistency, up to 8 oz. (237 mL). Ready to use
after mixing.
Application
Apply mortar using flat side of trowel to promote better substrate contact, then
comb in one direction with the notched side of the trowel. Spread only an area
that can be tiled while surface is still tacky (typically 20-30 minutes). Press tiles
into setting bed, then push in a direction perpendicular to the notched trowel
ridges to achieve optimum coverage. Apply mortar in a heavy enough layer so that
complete contact (no voids) between mortar and tile is accomplished when tile is
positioned. It may be necessary to “back-butter” large tiles to achieve complete
coverage and firm support. Periodically remove and check a tile to assure proper
coverage. Keep a minimum of
2
⁄3 of the joint depth between tiles for grouting.
Average pot-life of 1Flex
®
Fast Set mortar is 45-75 minutes. Stir occasionally
during use to maintain the smooth, creamy consistency of the product. Do not
add additional water.
Clean-up
Clean tools, hands, and excess materials from face of tile immediately (while
mortar is still fresh) with warm soapy water. Material that is cured is difficult or
impossible to remove.
Grouting/Curing
Grouting may be accomplished when tiles are held firmly in place, typically 4
hours after installation is completed. No traffic is permitted over the tiles prior to
grouting. Cold temperatures or high humidity may extend curing time. The use of
TEC
®
brand grouts is highly recommended.
