Blast cleaning (sandblasting, grit-
A typical sandblasting rig consists of a high powered air-
The abrasive material used can be calcium silicate, calcium carbonate, granules of iron silicate (chilled iron), silicon carbide, glass grit produced from recycled bottle bank glass, aluminium oxide, garnet and even walnut shells! Abrasive materials are available in many different sizes, from dust to 3.5mm.
Items which can be cleaned by our company vary from wood, soft stone, brick and masonry, through to aluminium, iron and steel. It is "simply" a case of determining the correct material and pressure to accomplish the task. For instance, wood or soft stone would be sandblasted at very low pressure using the finest grade of sand available, whereas iron or steel can be cleaned at full pressure using 2.5mm chilled iron, if necessary. It is advisable to apply a first coat of primer to freshly blasted metal to prevent the onset of corrosion, and this can be carried out by Steadblast using spray, roller or brush.
Dust nuisance can be effectively controlled, where appropriate, by using our Sat-
If the use of water is not appropriate, we can still blast "dry" at very low pressure and have dust extraction equipment which will remove dust from confined spaces.
Due to the unpredictable nature of this work, and in order to gain an idea of the cost of the cleaning, it is sometimes necessary to carry out a "test patch" on the item in question; to ascertain the amount of time and material that will be required to remove the layers of paint etc without damaging the surface of the item itself.
