Mortars & Grouts

A dry, factory-blended plaster mortar used as the first and second coat for lath and plaster applications. MAC formulation reduces lime content which aids in efflorsence mititation, while fiber adds flexibility to reduce cracks. With low shrinkage, excellent workability, high strength, efflorescence resistance, and product consistency, OBP MAC Scratch & Brown w/ Fiber provides a better base for VBM Bonding Mortars than typical plastic cement jobsite mixes.
