Introduction

When it comes to achieving a strong and durable finish in masonry, the concrete scratch coat plays a vital role. This initial layer of mortar is applied to surfaces such as walls or concrete blocks, providing a textured base that enhances the bond for additional layers of plaster or stucco. The scratch coat is typically composed of a mixture of sand, cement, and water, which is spread over the surface and then scored with a tool to create grooves. This not only improves adhesion but also helps in leveling out uneven surfaces.
