Blackfriar Acid Etch

Blackfriar Acid Etch is a versatile preparation solution tailored for concrete and screed floors, serving as an essential step before the application of sealing, coating, or painting. Its core function lies in the effective removal of excess lime dust, often referred to as laitance, a common culprit that can compromise the adhesion quality of subsequent floor coatings.

This specialized solution excels in etching a variety of surfaces, including power-floated, extremely smooth, hard, or chemically treated concrete floors. By doing so, it creates a textured surface that enhances the adhesion properties of the floor coatings to be applied later. It's important to note that Blackfriar Acid Etch is solvent-based, and for optimal results, it should be applied using either a stiff brush or a squeegee mop. After application, allowing a curing period of 2-3 days is advisable, ensuring the surface achieves a robust, ready-to-paint or coat condition.
