Hydrocloric Acid is ideal for etching new concrete floors, unpainted floors in preparation for painting with Epotread.  Also used for etching paths and driveways prior to sealing with Cob Glaze.

It is important to let the acid neutralize on the concrete surface, then thoroughly waterblast to remove loose cement material and fine agreegate.

Hydrochloric Acid is also known as Spirits of Salts and is commonly used for brick cleaning.

Only use Hydrochloric Acid on bare concrete, not on painted surfaces.  


  1. Dilute Hydrochloric Acid with water as directed (usually about 5 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 30 minutes to ensure the acid has neutralised, then thoroughly waterblast the surface.

Typical coverage on new or near-new concrete floors:

20 litres - 150 square metres.

5 litres - 35 square metres.
