Doff Paint Removal
Here at Pembrokeshire Limework we have recently purchased the new and exciting Doff machine, the best tool for removing paint. The super heated steam and low pressure makes a great combination for paint removal. This machine is also ideal for algae, moss and any harmful emissions from the atmosphere.
The Doff removes paint from any masonry surfaces i.e stone, brick, slate and also terracotta – it is especially kind to soft stone like sandstone.
What surfaces can the Doff be used on
We recommend the Doff for the use on surfaces such as brick, stone, concrete, tiled, glazed, encaustic wood, faience and terracotta. It is also a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories This is not harsh, unlike sand blasting, but is very effective on older buildings, oak beams, sandstone and a build up of carbon emissions, which is harmful to soft materials.
Where can the Doff be used
The Doff can be used in building restoration, industry, food production, hygiene control, hospitals, factories. Transport and vehicle depots, workshops etc
- Paint coatings/removal
- Algae, moss and fungi
- Certain types of graffiti
- Bird or vermin fouling
- Wax coatings
- Chewing gum
- Bitumen, Oil
Grease and many others, all without causing any damage or disfiguring the substrate.
How does the Doff work
A normal water supply is taken through the pump into the hot box, where a range of temperatures of up to 150 celsius can be achieved. The low volume of super heated water and steam (5 litres per minute) is then fed through heat resistant hoses to special nozzles where a genuine 150 celsius is delivered. The surface being cleaned does not suffer any damaging pressure, thermal shock or deep saturation and dries within minutes.

Usage
Effective
We have a Grade 2 listed Welsh slate farmhouse that has a thick “waterproof” paint / plastic coating on the front wall, up to 1mm thick. This is the worst thing you can do to a traditionally built house, old houses were built with earth lime mortar, and need to be able to breathe else you will end up with all kinds of damp problems such as damp walls inside and rotten floor timbers. We have tried to get the coating off using mortar picks, this works but is very, very tedious, takes ages and is very tiring. We learnt that Jason of Pembrokeshire Limework was getting the Doff machine which is (probably) the most westerly in Wales. The Doff machine uses superheated steam to gently heat up paint and other substances to 150C, and then the paint literally falls off. It is not harsh or forceful like a jet wash, or abrasive like sandblasting. When Jason had done a test panel, we found that it had got the slate cleaner than we had using mortar picks, and it had not disturbed the relatively soft earth lime mortar, or the remaining lime pointing.
