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)

What our Clients Think


See all testimonials
  • We would confirm Purple Rhino undertook the cleaning of ten large internal courtyard areas at the above hospital. As may be expected with hospital work complications did arise particularly from The Trust who had concerns with regards to patients in individual wards all of which were adjacent to the working areas. Not withstanding these problems Purple Rhino worked quickly and diligently with all parties so as to mitigate the issues and were able to complete in a timely and expeditious manner. All parties, including The Trust, were most appreciative with the quality of the completed works. In view of these experiences with Purple Rhino, we would not hesitate to recommend them for any future works relating to cleaning facades.
