Super Flex' Premium Latex Modified Thin Set Mortar   
Whether for new construction or renovation, Super Flex premium latex mortar delivers unsurpassed bonding strength with virtually any tile and substrate combination. Perfect for porcelain and glass.     
Super Flex mortar's high polymer solids content, together with its special adhesion promoter, ZS-100, give you unparalleled bond strengths. 
For best results, maintain all tiling materials, substrates, room andadhesives at 50°-70°F (10-21°C) for 24 hours before and 48 hours after installation. Thoroughly mix 50 lbs. (22.68 kg) Super Flex with41⁄2 to 6 quarts (4.3-5.7 L) clean, cool water.  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.. 
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.

I need to know if this will work with glass tile in a pool?

Does this product work for salt water hot tub?
A shopper on Feb 24, 2021
can this product be used to lay tile over tile ?
A shopper on Oct 22, 2018
BEST ANSWER: Yes. I first did a lot of work with diamond saw blades and drills to scarify the older tiles. I cleaned the mineral build-up as well because it seems it would weaken the seal. The hard part for me was filling in broken or missing tiles to provide a flat backing. The mortar tends to work best when it can be spread thin. If I tried to use mortar for the fill, it shrunk and pulled the tile out of alignment with the tiles around it.
Can this be used under ditra heat or similar membrane to bond to cutback residue on concrete?
