OBP Scratch & Brown

OBP Scratch & Brown mortars are dry, factory-blended plaster mortars used as the first and second coats for all types of cement applications, among other uses. 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. OBP Scratch & Brown is used as the first coat (scratch) and the second coat (brown) for all types of Portland Cement lath and plaster applications. It is used on interior and exterior base coats for stucco decorative wall systems. It may be used on shower walls and Portland Cement mortar beds for veneer and tile applications.
