This experience enables us to choose the most effective and gentle method needed to complete any given project cost effectively, with no damage to the substrate.

Therma Tech System
For the gentle removal of Flexible Paints, Graffiti, Algae, Moss and more
The DOFF System is unique in achieving temperatures up to 150 degrees at the nozzle end - making it a 'superheated water system'. Designed and developed to effectively remove paint, biological matter and general dirt and grime without causing harm or shock to the substrate.
What can DOFF be used for?
The steam/superheated water will remove paint, moss, algae, fungi and other biological matter and will also kill off spores. This means there's then no need to use a chemical biocide during the removal process or as a protection against further biological activity.
How does it work?
DOFF cleans stonework and masonry using high-temperature steam. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.
With absolutly 0% surface damage.
We recommend the DOFF for use on surfaces such as brick, stone, concrete, tiled (glazed and encaustic), wood, faience and terracotta. It is a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories.
