URGENT: Tiling & Grouting in Hot Weather
Technical Data Sheets - 1018 Hot Weather Tiling and Grouting
To get the most out of LATICRETE products during hot weather installations please take note:
Conventional Portland cement tile-setting beds, thin-set mortars, cement plasters and stuccos are often permanently damaged when subject to hot, dry temperatures or desert climates immediately after installation. High temperatures remove the water content of the mortar required for Portland cement hydration, curing and strength development. In addition, rapid drying often causes mortar to crack, crumble or lose bond. Waterproofing membranes, anti-fracture membranes, epoxy adhesives, epoxy grouts, epoxy waterproofing membranes and most other 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, monitor the surface temperature of the installation.
With the extreme high temperatures we are currently experiencing, there is a simple rule to follow when an installation is subjected to high temperatures: The 10ºC Rule – for every 10ºC above 21ºC, Portland cement and epoxy based materials take half as long to cure.
