Limitations
Recommended as a mortar additive only. Do not use XtraFlex additive as an
admixture for portland cement grouts. Latex-modified mortars should not be used
for installing green marble, other moisture-sensitive stone tile or resin-backed
marble; use TEC AccuColor EFX
®
Epoxy Grout and Mortar (TA-440). Latex-
modified mortars should not be applied when the temperature of the area and
substrate to be tiled is below 50°F (10°C) as this delays the curing process.
