MADRAS Concentrated Buffered Acid 1AT — 2 Liters — Fume-Free Inhibited Acid — Removes Efflorescence and Limescale — Floor Cleaning — Muriatic Acid Replacement
MADRAS Concentrated Buffered Acid 1AT is an inhibited (buffered) acid specifically formulated for the cleaning of natural stone, terracotta, stoneware, and other stone surfaces before treatment with protective products. Thanks to its inhibited and buffered formulation, it does not produce irritating fumes and reacts more slowly than standard muriatic acid, ensuring greater safety during use. It replaces muriatic acid in both routine and heavy-duty cleaning applications. Essential for preparing surfaces before applying impregnating products, sealants, and protective treatments. Concentrated 2-liter format. Never use undiluted: always dilute before use.
- Inhibited (buffered) formulation — does not produce irritating fumes
- Slowed reaction — safer and easier to control than muriatic acid
- Concentrated — dilute before use according to instructions
- Removes efflorescence and limescale from floors and stone surfaces
- Surface preparation before applying impregnating products, sealants, and protective treatments
- Replaces muriatic acid in cleaning applications
- Format: 2 liters
- SKU: 1AT2X12 | EAN: 8022939448205
Main features
- Inhibited (buffered) acid: the inhibited formulation reduces the acid's reactivity, slowing the chemical reaction. This makes it safer to use than pure muriatic acid, with a lower risk of damage to surfaces and the user
- Fume-free: unlike standard muriatic acid, which produces irritating and corrosive hydrochloric acid fumes, MADRAS Acid 1AT does not produce significant fumes under normal conditions of use, improving user safety
- Removes efflorescence and limescale: effective chemical action against deposits of efflorescence (salt efflorescence) and limescale that form on stone, terracotta, stoneware, and other stone surfaces
- Surface preparation: essential for cleaning and preparing surfaces before applying impregnating products (such as MADRAS 1AS), terrace sealants, and other protective treatments. A clean surface ensures better adhesion and penetration of subsequent products
- Concentrated: the concentrated format allows the product to be dosed according to the intensity of the dirt and the type of surface, optimizing consumption

Frequently Asked Questions (FAQ)
Q: What is the difference between buffered acid and muriatic acid?
A: Standard muriatic acid is pure hydrochloric acid, which is highly aggressive and produces irritating and corrosive fumes. MADRAS Acid 1AT is inhibited (buffered): it reacts more slowly, does not produce significant fumes, and is safer to use while still providing effective cleaning action against efflorescence and limescale.
Q: How do I dilute the product?
A: The product is concentrated and must never be used undiluted. Dilution ratios depend on the type of surface and the intensity of the dirt. Consult the instructions on the label or contact MADRAS for specific ratios.
Q: Is it suitable for marble?
A: Acids can damage marble and limestone. Always check compatibility with the type of surface before use and test on a small, inconspicuous area. Specific neutral products are recommended for marble.
Q: Can I use it after applying an impregnating product?
A: No. Buffered acid should be used before treatment with impregnating products and sealants as part of the surface cleaning and preparation process. Do not apply to surfaces already treated with protective products.
