ARDEX PU 30 is a ready-to-use, one component, low-emission polyurethane primer and moisture barrier for absorbent and non-absorbent subfloors. When fully dry, two coats of ARDEX PU 30 produces a membrane which can accommodate hygrometer readings up to 98% RH. ARDEX PU 30 meets the requirement guidelines for the EMICODE licence ‘EC1 PLUS’, achieving the lowest possible emission limits.
ARDEX PU 30 can be used as a primer to penetrate, strengthen, and stabilise dusty, friable, or weak subfloors, or as a moisture barrier (two coats) for substrates in both internal and covered external areas i.e. garage floors.
