Sandblasting and cleaning
Other cleaning methods: chemical treatments
This new procedure allows room for the recovery of artistic elements and more. Less invading than sand blasting, it doesn’t require the use of big equipment and wouldn’t cause dust pollution nearby the work site. With the use of appropriate chemicals for each type of material, it possible to achieve good results.
Innovative methods: Shot blasting
In 2003 Ramella Graniti were among the first companies to perceive the potential of the shot blasting machines with all their advantages such as: speed, capability to work on materials with a minimum of 1cm thickness, antique effect of the tiles edges. By that time our company installed such equipment for working on floors and solid blocks. Recently there’s a bigger machine meant for slabs of up to 200cm in width and 40cm thickness. Apart from the economical advantages, there are other benefits such as working for third parties on “old” sets of slabs or cut out polished elements to give them a revamped appearance. It’s also possible to carry out stripping of paint from steel structures like gates, hand rails, heating radiators, girders etc. The shot blasting process is suitable for granite and marble slabs. This method produces a natural effect on the surface (top face and edges) of the slabs which is similar to the traditional bush hammering and flaming process but at a much cheaper cost and higher execution speed. Works done on capitals (diamond bit), copings, staircases, kerb stones can reach a cost saving of more than 50% compared to flaming and of 80% as against bush hammering.
Manual methods with honing and brushing machines
It’s possible to carry out an effective cleaning of floors, wall linings, columns, balconies etc. which isn’t invasive and does not require the use of water or sand.
