Cleaning render and stone on exterior of buildings using DOFF

Solution

An exclusion or warning zone will be set up around the area of work using cones; tape and warning signs will be posted in any area where a hosepipe crosses a walkway, to warn of a potential trip hazard.
Assess the situation prior to commencing work. Ensure that there is no danger to the public – cordon off areas if required.
Ensure that the poles will not come into contact with any electric cables or overhead power lines.
Ensure that any falling residue water does not create a danger of slipping. You must use De – Ionised water when using water fed poles.
Poles are extended at ground level sufficient to reach the high level windows or building fabric.
Poles over 15 metres overall length require x2 operatives to extend the pole to the correct height to avoid manual handling issues.

Only Stonehealth approved operator to use the Doff equipment.
All areas that are cleaned using the DOFF will involve a small amount of water pooling nearby.
Safety signs and barrier tape MUST be used to safely cordon off your work areas.
Steam cleaning at extremely low pressure – 50 BAR MAX with water flow of only up to 5 litres per minute will completely remove all organic matter and atmospheric pollution, from the surface of the area cleaned. We will also apply under controlled conditions a SoftWash solution to help prevent re growth occurring (this product is comparable to a biocide, and in our opinion works much better)
