Product Description Acid Etch for Floors is a solution that prepares floors for painting fresh concrete that is less than six months old. Surface alkalinity needs to be neutralised by etching. This is down to the fact that high alkalinity is not ideal for single pack alkyd based paints. This is when cement floor etching is required. Its main purpose is to remove surface laitance, (which is a fine layer that forms after the floor cures). This creates a porous substrate better known as a “key” for the paint to fully adhere to the floor that does not easily peel away from the surface. Please note that if the floor etching does not start to foam at the concrete’s surface, the surface may be sealed or polished and will require light ablation in order to produce a porous surface Acid Etch for Floors contains a diluted hydrochloric acid base that reduces the alkaline content of new concrete floors (the floor must be at least four weeks old) or create a key on very smooth floors. This allows the topcoat to adhere to the surface. Apply with a watering can in a ribbon motion. Scrub with a stiff bristle broom, especially heavily stain areas. Wash off with a high powered hose. Sweep excess water and allow to completely dry. This creates a profile for the coating to adhere to, and prevents peel up.
