Conventional Portland cement based tile & stone installation mortar beds, thin-set adhesive mortars, PC/Sand based grouts, cement renders, screeds & plasters and stuccos are often permanently damaged when subject to hot, dry temperatures or dry environments immediately after installation.
High temperatures remove the water content of the mortar required for proper Portland cement hydration, curing and strength development.
In addition, rapid drying often causes adhesives, grouts & mortars to crack, crumble or lose bond. Waterproofing membranes, anti-fracture membranes, epoxy adhesives, epoxy grouts, epoxy waterproofing membranes, underlayments and most other tile & stone installation products will also be affected by hot working temperatures.
Flash setting and reduced working time can result. It is important to note that surface temperature is more important than air temperature. Therefore be sure to be aware of and monitor the surface temperature of the installation.
