S-777 THIN SET MORTAR PRODUCT DESCRIPTION: S-777 is a dual-purpose thin set mortar for floors and walls. S-777 has good compressive strength, high bond strength, is easy to trowel and meets or exceeds ANSI A118.1 requirements. S-777 exhibits superior bond strength, excellent freeze-thaw stability, increased flexural strength and water resistance when mixed with S-800 in place of water. In addition, when mixed with S-810, the S-777 exhibits superior flexibility. When S-777 is mixed with S-800 or S-810 the system meets or exceeds both ANSI A118.4 and A118.11 specifications. USES: S-777 is recommended to set any type of ceramic tile specified for floor and wall installation when tile is set in accordance with ANSI A 108 and the Tile Council of North America's Handbook for Ceramic, Glass, and Stone Tile Installations. S-777 may be used over concrete, dry walls, glass mesh mortar units and wood subfloor with mortar bed substrate, masonry, ceramic tile or brick. LIMITATIONS: S-777 should cure 48 hours before pedestrian traffic is permitted. If installation is in a high moisture area 14 days to 28 days is required. Extremely high temperatures or low humidity can reduce open time by as much as 20 minutes. TECHNICAL DATA: Physical Properties S-777 meets or exceeds ANSI A118.1 specifications.

Pot life approximately 80 to 90 minutes @ 73°F and 50% RH.

INSTALLATION: Substrate: Substrate must be free from dust, oil or grease and meet ANSI and TCNA specifications. Mixing: Mix S-777 slowly into clean, cool, potable water or latex additive (for superior bond strength, excellent freeze-thaw stability, increased flexural strength and water resistance). Mix thoroughly until a workable (paste like) consistency is obtained. NOTE: For best results, add S-777 to water or latex additive, not water or latex additive to S-777. Allow to slake for 5 to 10 minutes depending on temperature or humidity and then re-mix adding liquid or S-777 powder as necessary....
