Procedural adjustments should be made when setting and grouting 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:
- Keep epoxy liquids stored at room temperature (70 degrees) for 12 to 24 hours before use. Cold liquids can be warmed by placing unopened containers in warm water.
- Epoxy liquids are freeze/thaw stable. Frozen liquids can be thawed at room temperature or by placing in warm water.
- Cold temperature will make epoxy stiffer to work with and extend set 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 degrees should be protected at least 32 hours.
- For best results, surface temperatures should be between 60 degrees and 90 degrees.
- Consider using these products specifically designed for use in very cold weather. US SPEC Gelbond Sub-Zero is designed to gun at -15 degrees.
- Consult manufacturer's recommendation for epoxy usage when optimum conditions do not exist.
