Directions:

  1. Dilute Hydrochloric Acid with water as directed (usually about 7 parts water to 1 part acid).
  2. Apply to floor area using plastic watering can, or mop onto the floor using a soft broom and bucket.
  3. Scrub in with a broom for 3 minutes, take care not to splash acid onto walls, door rails, etc.
  4. Wait for 1 hour 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 - 200 square metres.

5 litres - 50 square metres.

 

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