ProPOXY MoistureBLOK (MB) S-HARDENER

ProPOXY MoistureBLOK (MB) S-HARDENER is a slower-curing companion to MB Resin, also used at a 2:1 ratio. It allows for extended open time and working flexibility on larger jobs or where precise installation is necessary. The longer working time ensures full wetting of the slab and consistent coverage. It is ideal for large commercial or industrial slabs and in hot climates where fast-cure materials may flash too quickly. Despite the slower cure, it achieves the same vapor-blocking performance and strong adhesion expected from MB systems.
