System Application How to clean Render Walls
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 3-24 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.

EXTERIOR CLEANING CONTRACTOR
High Pressure washing can damage natural
stone and is best avoided Softwashing is the
preferred method for cleaning Natural Stone but
super-heated water at very low pressure can
also be used.
The Softwash system we use can not only clean
the stone but can have residual benefits.
