Installation of Epoxy Adhesives and Grouts During Cold Weather

Procedural adjustments should be made when setting and grouting with epoxies during periods of cold temperatures. Cold epoxy liquids, along with air and surface temperatures, can cause workability problems and slow the curing process. Observe the following recommendations for best results under cold weather conditions.

1. Keep epoxy liquids stored at room temperature (70°F) for 12-24 hours before use. Cold liquids can be warmed by placing unopened jars in warm water.
2. Epoxy liquids are freeze/thaw stable. Frozen liquids can be thawed at room temperature or by placing in warm water.
3. Cold temperatures will make epoxy stiffer to work with and extend open time. Mixing, spreading, grouting, and cleanup will require additional attention if done in cooler temperatures. Completed work should be protected from foot traffic for longer periods. A floor grouted at 50°F should be protected at least 32 hours.
4. For best results, surface temperatures should be between 60°F and 90°F.
5. Consult manufacturers' recommendations for epoxy usage when optimum conditions do not exist.
