ST-20 is a specially blended formula of chemicals, developed to remove road film and other deposits quickly and effectively from stone, brick and rendered surfaces.

ST-20 will quickly remove the most stubborn of soiling from stone, brick, render and other exterior surfaces. ST-20 can be applied by brush, spray or pressure washer. ST-20 is safe to use on most exterior surfaces including aluminium and galvanised surfaces.
ST-20 can be used to remove algae & mould in a lot of cases, however sometimes you may need to apply a product designed specifically for this purpose to remove any ingrained or hard to remove algae mould. For surfaces that are heavily soiled with algae and mould we recommend cleaning first with ST-20 as this will remove the road film and carbon deposits that algae treatments will not remove on their own.
*Algae and mould stains can sometimes be difficult to remove with a detergent type product depending on the surface type and how deeply the stain has worked into the material. In these cases we would recommend applying our AM-100 Algae, Mould and Mildew Remover after cleaning with ST-20 Stone & Render Cleaner.
Directions: Test for compatibility before use. For best results use through a pressure washer at 2-5%. Alternatively mix 1 part ST-20 with up to 20 parts water in a bucket and apply with a stiff brush. For heavily soiled areas use a stronger mix such as 1 part ST-20 to 10 parts water. Allow product to work for 5 minutes than rinse with clean water. Ensure all areas have been fully rinsed. Do not allow product to dry.
