Dual action etchant which cleans and prepares bare concrete prior to painting.
Areas of use:
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:
Colour change system – when the pink liquid turns clear you know the job is done.
Hydrochloric acid based etchant blended with water based degreasers.
