LD3 is a versatile,100% solids, epoxy resin system that can be used as a vapor suppression, broadcast priming and crack repair. LD3 is designed for use over existing concrete where the level of moisture emissions from the slab exceeds the maximum allowed by the manufacturer of the finished floor covering. It also can be used on new projects where schedules do not allow for freshly poured concrete to fully cure.

Applied in just one coat, LD3 will reduce unlimited MVER or up to 100% RH (per ASTM F-2170) to below 3 lbs.
