5. INSTALLATION INSTRUCTIONS
Mixing
For best results, maintain all tiling materials, substrates, room and adhesives at
50°-70°F (10-21°C) for 24 hours before installation. Maintain recommended
room temperature for 48 hours after installation. In a clean mixing container, add
Super Flex™ mortar to clean, cool water as specified in the chart.

Add powder to liquid for ease of mixing. Mix material to a thick creamy
consistency. Avoid breathing dust and contact with eyes and skin. Allow the
mortar to stand for 10 minutes. Remix and apply. Avoid using high speed mixing,
not to exceed 300 rpm, to prevent entraining air.
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.
Open time and tile hand adjustability may vary with job site conditions. 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, while mortar is still
fresh, with warm soapy water.
Grouting/Curing
Grouting may be accomplished when tiles are held firmly in place, typically 16 to
24 hours after installation is completed. No traffic is permitted over the tiles prior
to grouting. Cold temperatures or high humidity may extend curing time. Unglazed
tiles may require sealing prior to grouting so discolorations will not occur. The use
of TEC
®
brand grouts is highly recommended.
