Comparison: EFF-STOP® vs Benjamin Moore Masonry Primers
Why choose EFF-STOP® over Benjamin Moore’s Fresh Start or Ultra Spec Masonry Primers?
EFF-STOP® offers epoxy-fortified protection specifically formulated for high-pH masonry surfaces
Dunn-Edwards provides better efflorescence resistance on porous substrates like stucco and block
Benjamin Moore’s acrylic primers are versatile but may require additional coats for alkali resistance
EFF-STOP® is optimized for both interior and exterior use, while some Benjamin Moore primers are limited by VOC regulations

Why choose EFF-STOP® over Sherwin-Williams LOXON®?
EFF-STOP® tolerates a wider pH range (up to 13), ideal for new or cured masonry
Dunn-Edwards’ epoxy-fortified formula offers superior adhesion and long-term protection
