Etch & Clean

A highly effective hydrochloric acid based etchant which removes surface laitance (a weak, cementitious dusty layer) from new, bare concrete prior to painting. The product's dual action formula both etches (provides a key) and cleans bare concrete ready for painting in one simple application.

Etch & Clean reduces the alkalinity in new concrete and has a thick, gel-like consistency which allows greater control when applying the product to the floor. This results in a more evenly etched finish and so promotes more effective paint adhesion. To help with application, a pH indicator changes from pink to clear once the surface has been prepared effectively.

Features and benefits:

• Etches bare concrete to promote adhesion of paint finishes.
• Removes dirt and light oil deposits.
• Removes cement deposits from new concrete to ensure good paint adhesion.
• Reduces alkalinity of new concrete – essential prior to application of single pack paints such as Watco Concrete Floor Paint.
• Easy to use – unique gel formulation allows even etching.
• Colour change system – when the pink liquid turns clear you know the job is done.
