Roughcast is a common decorative finish on many exterior houses. The cast over time captures small dirt particles this allows bacterial growth to establish which appears as red, green or black staining. This staining is more obvious on the walls that take the brunt of the weather but can be on all walls. The biofilm staining can be removed from the wall using our Softwash systems.
Cleaning up Roughcast
Pressure Washing at a high pressure is not recommended to clean wall as the force of the jet will dislodge the dash. Softwashing is the preferred method for the cleaning of Pebble Dash and Roughcast this non-invasive system uses chemicals to remove the staining rather than force.

System 1: The hypochlorite solution is sprayed onto the wall and then left for 30-60 minutes before being rinsed of. It may require more than 1 treatment to bring the walls up to an acceptable standard. The final step of the process is to treat the wall with the inhibitor solution. Results are normally seen within 72 hours of application. System 2:   The application of a (DDAC) solution. The wall is saturated with the solution which is not rinsed off but just left to dry.  This system can take up to 1 year to fully clean but some noticeable difference should be seen within a few months.
