• Rendered surfaces and masonry walls

• Cleaning before sealing to improve adhesion and finish quality

Application & Benefits:
Before using, ensure surfaces are clean and damp to help prevent burning. Apply the remover so the product can react with the efflorescence; you will often see fizzing as the acids work. Then simply rinse thoroughly with clean water to wash salts and residues away. This step also strips away dirt and grime, giving you a clean base for sealing or further treatment. Always test on a small, inconspicuous area first to confirm results and surface reaction.
