Saltsyra 9%

The product is used for etching concrete floors to remove the cement skin before painting. The hydrochloric acid chemically reacts with the alkaline cement skin, which dissolves, and water and salts are formed.

The product is used for etching concrete floors to remove the cement film before painting.

Can be diluted 1:1 with water.
Remember to pour the acid into the water and not the other way around to avoid a chemical reaction!

The hydrochloric acid is poured onto the floor and spread with a brush. The acid reacts with the cement layer and it foams and bubbles on the concrete surface. Let it act for about 5 minutes. Repeat the treatment until no reaction is visible when hydrochloric acid is poured on. Rinse immediately with plenty of water. Let the floor dry before painting.

The product can never replace diamond grinding, which gives a more even and better result.
Not recommended for floors that will be subject to heavy use.

Note! Hydrochloric acid can be corrosive to metals, and remember that non-neutralized hydrochloric acid must not be poured down the drain.
