Graffiti removal using DOFF machine

The Stonehealth DOFF® machine’s water supply is fed via a pump into a hot-box where it is rapidly heated to temperatures of up to 150. The output temperature and pressure can be set by the operator as required. This superheated water is then fed through high-temperature heat-resistant hoses to the nozzle at a rate of between 3-5 litres per minute to provide exceptional cleaning capability and is commonly used to remove: Paint coatings (most oil and plastic types) Graffiti Algae, moss, and fungi Wax coatings Chewing gum Bitumen, oil, grease, and much more … all without damaging, disfiguring, or discoloring the substrate. The surface being cleaned does not suffer any damaging pressure, thermal shock, or deep saturation, and once cleaned, the surface dries within minutes, preventing any long-term damage resulting from trapped moisture. The DOFF® Integra is recommended for use on: Brickwork, Stone, Concrete, Tiles
