TEC Full Flex- Premium Thinset Mortar

Known for its superior handling and engineered for dependability. Full Flex Premium Thin Set Mortar is a contractor favorite. It’s designed for use over a generous array of new or renovation substrates in residential to extra heavy duty commercial applications. One step mixing, smooth and easy spreadability, prolonged pot-life, extended adjustability time and excellent coverage make Full Flex a practical, real value.

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 Full Flex mortar to clean, cool water as specified in the chart. Size Water 50 lbs. (22.68 kg) 1 to 11⁄4 gallons (3.8 to 4.7 L) 25 lbs. (11.34 kg) 2 to 21⁄2 quarts (1.9 to 2.4 L) 9.75 lbs. (4.42 kg) 1 to 11⁄4 quart (0.95 to 1.18 L).  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.

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 tools, hands, and excess materials from face of tile, while mortar is still fresh, with warm soapy water.

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.
