Disaggregates the constituent aggregates.
Dissolves the basic salts present in mortar, cement and concrete.
Has remarkable descaling power.
Leaves the pores in the surface clean and open, lifting traces of any adhering materials.
Strong diluting effect on iron oxide.
Removes rust from ferrous metals. The iron then needs to be passivated to prevent oxidation.
Corrosive (hydrochloric acid), causes burns. Do not mix with additives without prior consultation.
These instructions are merely recommendations based on our experience. We recommend performing tests for each new type of application or surface to be treated.
Datasheets(X)
For removing inorganic stains such as traces of concrete, cement mortar and rust.
Also recommended for exposed brick walls (pre-test to check that the product does not discolour the wall) that show traces of grouting mortar, to remove mortar residue from prefabricated parts, to clean concrete mixers and to clean out the remains in mixers and trucks.
Shake well before use. Use undiluted or dissolved in water up to a 1:2 ratio, depending on the needs of each surface. Ideally, use a hard brush to help the product penetrate. It is recommended that you start the application with solutions of 1:1 or 1:2 in water, then use more concentrated solutions if necessary. Leave the product to work for a minimum of 15-30 minutes and then rinse with plenty of water. When the product is applied, a chemical reaction occurs and creates foam. The action can be repeated until the cement or mortar residue is completely removed.
Apply from the top down when working on vertical surfaces.
Precautions
Contains inorganic acids that are strongly corrosive and oxidising to metals. It is best to wear gloves, goggles and protective clothing during use.
Exercise the utmost caution when using indoors.
Avoid contact with eyes, skin and mucous membranes. If such contact occurs, immediately flush with plenty of water and consult a doctor in case of an emergency.
Do not apply to marble, limestone, aluminium or materials sensitive to strong acids, as they may become damaged, dulled or discoloured. Properly protect surfaces that should not be treated.
Use water to clean tools and utensils impregnated with the cleaner.
