OBP MAC™ Scratch & Brown w/Fiber

OBP MAC™ Scratch & Brown w/Fiber is a dry, factory-blended plaster mortar used as the first and second coats for all types of cement applications, among other uses. MAC reduces lime content, while fiber adds flexibility to reduce cracks. With low shrinkage, excellent workability, high strength, efflorescence resistance, and product consistency, OBP Scratch & Brown provides a better base for VBM Bonding Mortars than typical plastic cement jobsite mixes.
