Hydrochloric Acid 20L

The acid washing of concrete is a requirement after the concrete has cured sufficiently, in order to remove surface efflorescence and to open the pores before sealing. This will help the sealer to penetrate and result in a superior bond between the sealer and the surface.

Floors that are acid washed before sealing will have greater colour enhancement and will appear darker than floors that have not been acid washed.
Acid washing is a critical process and should be approached with care and carried out in a controlled way. The correct protective clothing and safety gear should be worn whilst acid washing.
Requires appropriate dilution.
