Acid washing is a process used on concrete in preparation for Sealing. The acid helps to remove stains that are left on the concrete and also helps towards the colour consistency of the concrete.

Acid Washing the concrete cleans and opens the surface so a sealer can be applied.

We take the utmost care when performing Acid Washing at your property. All safety guidelines are followed strictly and disposal of any wash water and slurry is done in an environmentally free way.

Questions

Some questions we have been asked about this service.

ARE THERE DIFFERENT TYPES OR LEVELS OF ACID WASHING? Yes, there are 3 different levels of Acid Washing. A light Acid Wash is just enough to lightly clean the surface and open the concrete enough to apply Sealer. A medium Acid Wash is just enough to expose some of the fine sands in the concrete. A hard Acid Wash creates full exposure of the sand content in the concrete. This hard wash is good for non-slip purposes or for a 'burnt' look to coloured decorative concrete.
