Wood - Dry Blasting
A data sheet on our dry blasting cleaning services, a suitable summary for printing is available in PDF format, here
We specialise in using a low pressure sand jetting system that has been used nationwide for property restoration, including gaining approval for and subsequently working on many Listed Buildings.
The system, in our trained hands, causes minimal damage to an underlying surface and is flexible enough to tackle most property restoration cleaning tasks.
The low pressure sand jet can clean surfaces without injecting large quantities of water into the surface, and with minimal surface damage, at the same time, the 'damp' system also captures dirt and abrasive, preventing the health and safety risks associated with dry blasting.
However, the damp nature of the blast does mean that the abrasive and removed dirt / paint stick to surfaces (as can be seen in the wood - sand jet photographs) - this can be washed out, or left to dry and brushed out. But we have now re-discovered that dry blasting can, if the operator is careful, be quite effective, so we now offer that service as well. It is one of those 'swings and roundabouts' things - the dry blast will use more abrasive and create lots and lots of dust, but is perhaps a little easier to clean up on the day.
Internal beams are the typical wooden structures that we clean...
We can give no guarantees what your wood is like underneath the painted surface, and it is typical that builders paint all the beams one colour to disguise that one replaced beam doesn't match the others!
A painted pine roof in Sheffield cleaned in March 2009. A job that we were immensely proud of - a pity that the customer never paid for the work - or the brickwork on the outside of the building either!
a close up of that ceiling
This is another complete ceiling - in East Yorkshire
a wooden ceiling cleaned with dry blasting. Compare with the standard Sand Jet!
The sort of dust cloud generated inside that room (and house) when dry blasting! If you live in an open plan house and are fully carpeted, dry blasting can be slightly invasive! Compare this with the photographs elsewhere in this website! We need lots of ventilation and even then may need to stop and let the dust settle several times to make progress - and see how we are doing.
A wooden floor in a Huddersfield mill - demonstrating that sand blasting was an option for cleaning it- as an ex-mill floor it was extremely rough, and ordinary sanding machines were struggling. - we could clean it - and the existing roughness wasn't a problem - then a thick coat of varnish could un-roughen the floor afterwards. But note the amount of sand debris around from this small section!
This first picture is of a partially cleaned set of panels in a Grade II listed ex masonic lodge in Scarborough. We had experimented with chemical stripping - and found it ineffective (and heading towards expensive!) and adjusted our blast pot to work at a lower pressure than usual - with excellent results.
This next set of panels were in Harrogate in 2015.
In 2016 we were approached by a customer, who in moving house, found that his dark oak furniture no longer matched his living room. We successfully stripped the paint from the oak, and more or less got rid of the water stain on the table in the process!
- Dry - debris can be cleaned up relatively quickly and easily with brush and vacuum
- aggressive - rapid removal of material.
- Cleaning to the requirements of BS 8221-1&2 :2000 the British Standard Code of Practice for Cleaning and Surface repair of buildings.
