If you want to refurbish something that has a metallic surface, the first thing that you need to carry out is to remove the previous coating of paints, or the other particles that have settled on its surface due to various natural reactions such as rusting, corrosion, etc. Cleaning the surface of steelwork requires the need of a precise technique and shot blasting is the perfect answer to this call.
Steel preparation is not an easy task. All paint and corrosion needs to be completely removed, to leave bare metal, otherwise the new coating will fail, long before the estimate given by the manufacturer. Linishing, sanding, grinding and using nail guns and hot air-guns and scrapers is an extremely lengthy and laborious process. The mind-numbing nature of this work causes low morale and hence low productivity amongst your labour force.
However, shot blasting (or grit blasting) with a 2 man team, will accomplish the same amount of work as 20-30 men using hand tools – a massive saving in time and wages. The Sand blasting technique normally uses Iron silicate (copper slag) or recycled glass to produce a near white metal finish (SA 2.5) or white metal finish (SA 3).
The whole equipment is small enough to be taken to any place to carry out mobile sandblasting processes. It can be easily carried by a vehicle and doesn’t require much people to carry out the cleaning procedure. A two person team can be efficiently able to organise the machine and carry out the blasting process within a few minutes.
Sandblasting kit is extremely portable, and can be used to access areas that are long distances from the air compressor – hundreds of metres if the compressor is powerful enough. Mobile shot blasting rigs can be used to blast roller coasters, ships and barges, bridges and underground tunnels.
Modern mobile sand blasting systems have revolutionised steel preparation. They can be used from cherry-pickers and scissor lifts without the need for expensive scaffolding. Surfaces can be hit from several feet away without needing to provide close access.
Blast cleaning results in creating clean surfaces that can be refurbished according to the needs of the user. It can be steadily used to remove paints and rusts prior to application of coatings. that spoil the surface of a steelwork completely. The shot blasting method revives the original color of the metal which can be painted again so that they can be brought into any specific application, or can be used by the user as per their choice.
There are various traditional ways to remove paint from the walls of your commercial or residential property i.e. nail guns, paint stripper, sanding discs, hot air guns and scrapers etc. Paints are used to satiate two kinds of necessary purposes; the first one is to prevent the walls from letting in all kinds of contaminants due to which they may lose their quality, and the second one is to provide them with an aesthetic appeal. Traditional techniques used for removing paint are normally too labour intensive to be cost effective and most of them do not leave a good finish.
For fast and cost-effective paint removal from the surface of many substrates, such as concrete, metals, stone or brick, sandblasting is an ideal solution. The process is carried out with equipment that uses a high powered air compressor connected to the blasting pot which is connected to the blast nozzle using a required length of blast hose. Modern abrasives such as ultra-fine aluminum silicate and bicarbonate of soda allow selective removal of paint from delicate substrates such as Bath stone, sandstone and Portland stone.
A sandblaster uses a rig which comprises a high powered air compressor, which delivers the abrasive from the blast pot down the blast hose and out via the blast nozzle. The abrasive materials used in the process are calcium silicate, calcium carbonate, granules of iron silicate and even small bits of walnut and coconut shells. The abrasive that is normally used is recycled glass. However, dependent upon the application, there are a multitude of other abrasives available. From steel shot at one end of the spectrum which will remove thick mill scale, down to bicarbonate of soda at the other end, which will not even etch glass.
The process can also be used to remove paint from metallic surfaces such as iron gates and railings, tanks, silos, machinery and vehicles. large equipments created in a factory. The abrasion process can be easily carried on using the necessary materials. It is also suggested that after removing the paints from metallic surfaces, they should immediately be coated with primer, to prevent the onset of surface corrosion. be provided a single coat of primers so that it doesn’t start rusting again. Corrosion is a quick reaction and can take place easily. Thus, without wasting any time, the surface can be painted with a primer by Steadblast using a spray or a roller.
For Rust and paint removal from metal, using conventional methods is a highly tedious and labour intensive task. Sandblasting makes light work of this and can be used to prepare large areas of structural steelwork prior to recoating.
