Frequently Asked Questions

Can CRACKBOND 2100 MV be extended with sand for repair applications?
Yes, it can be extended using a 1:1 sand-to-epoxy ratio to produce a flowable grout or repair mortar for spall repair and patching.

Is CRACKBOND 2100 MV safe for use in drinking water applications?
Yes. It is certified to NSF/ANSI 61 and 372, making it suitable for potable water system components.

What is the working temperature range for installation?
CRACKBOND 2100 MV can be applied in ambient conditions between 40°F and 100°F.

What is the best way to apply this epoxy as a coating or bonding agent?
Use a roller or brush to apply evenly to prepared concrete or steel surfaces. Fresh concrete should be placed while the epoxy is still tacky.

What is the difference between CRACKBOND 2100 MV and 2100 MV-LPL?
The LPL version has a longer pot life and working time, which is beneficial in warm temperatures or large-volume applications.
