  2. Apply to floor area using plastic watering can, or mop onto the floor using a soft broom and bucket.

  4. Wait for 30 minutes to ensure the acid has neutralised, then thoroughly waterblast the surface.

Used for etching bare concrete floors in preparation for painting. Hydrochloric Acid will react with cement in the concrete to roughen the surface slightly. This provides a better bond for the floor coatings.  

Typical coverage on new or near-new concrete floors:

20 litres - 120 square metres.

5 litres - 30 square metres.


Some concrete floors may require more (or less) acid, depending on the hardness and strength of the concrete.
