Why epoxy grout crack.

 

Epoxy grout is a high-strength and durable material, and if installed properly, it is less likely to crack than cementitious grout. However, like any other material, epoxy grout may crack under certain circumstances. Here are some reasons why epoxy grout may crack:

 

Incorrect mixing: If the two components of the epoxy grout are not mixed in the correct ratio, the grout may not cure properly, resulting in cracking.

 

Inadequate substrate preparation: If the surface is not properly cleaned, dried, or leveled before installing epoxy grout, it may lead to improper bonding and eventually cracking.

 

Excessive movement: Epoxy grout is more rigid than cementitious grout, so it may not be suitable for areas with excessive movement or vibration.

 

Temperature changes: If the temperature changes significantly, the expansion and contraction of the substrate may cause cracking of the epoxy grout.

 

Overall, epoxy grout is less likely to crack than cementitious grout, but proper installation, substrate preparation, and environmental conditions are crucial to ensure its long-term durability.
