GRIPCRETE 166 Acrylic Masonry & Plaster Primer

MASONRY & PLASTER PRIMER is specifically formulated to prime and seal masonry surfaces against alkali and efflorescence. Use on above-grade masonry and plaster surfaces to protect subsequent finishes from breakdown and burn-through caused by elevated pH levels. Minimize downtime and trade disruption by coating fresh masonry and plaster in as
little as seven days.

MASONRY & PLASTER PRIMER is the ideal primer for interior and exterior smooth masonry surfaces. Protecting from alkali and efflorescence make it ideal for tilt-up and poured concreted, block, brick, stucco, EIFS, and plank siding. Tolerating pH levels of 7-13, allows for worry-free application to new, “hot” interior plaster.
