Will brick cleaning with muriatic acid affect the mortar?
Masonry projects that use cement, concrete and mortar can be extremely messy and cause a lot of potential costs if not cleaned properly at the time. Muriatic is a very strong acid that is commonly used to clean dried cement products from stone, brick, and other masonry surfaces. Although this is a strong, powerful product that does work effectively, it can be hugely damaging to the substrate surface, sometimes causing more costly damage than was there in the first place. The best alternative to removing unwanted dried cement products is to use APT’s Extreme Wash 80. This extra strength blend of hydrochloric acids and surfactants allows for the deepest penetration and increased action to ensure rapid removal of unwanted deposits from the surface, without causing any damage to the substrate.
Can I use this on newly built walls or paving?
Yes, it’s ideal for builder's cleans after bricklaying or pointing work. Always test a small area first and use appropriate PPE for safety.
