Post-Construction Cleaner

Louis XIII Post-Construction Stripper is specially designed to effectively clean residues left behind after installation or renovation, such as the white film of cement, lime, plaster, or limescale on tiles, floor tiles, terracotta, natural stone, and other mineral surfaces. Its formula, free of hydrochloric acid but rich in phosphoric acid, guarantees powerful action while preserving the integrity of the tiles and joints. It also eliminates traces of saltpeter, rust, oil, and other construction site grime. Ideal for restoring the original appearance of surfaces after work, while preparing porous substrates to receive anti-stain protection.

• Concentrated phosphoric acid
• Specific cleaning agents
• Hydrochloric acid-free (respects sensitive materials)
