Our Eco Soda Blast cleaning system can transform your building, restoring your stone surfaces it to its former glory – all without causing any damage to the brick or stone work. It can even remove several layers of paint that have accumulated over the years, revealing the original brick or stone underneath.
We understand that preserving your original brick or stone work is paramount. Our trained professionals adjust the Eco Soda Blast equipment to suit the exact needs of your building so that even ornate stone work can be cleaned effectively without causing any damage to the surface.
Stone cleaning is a specialist task ,Soda blasting doesn’t work by abrading the surface, as sand blasting or bead blasting would, making it an excellent stone and brick cleaning method.
During soda blasting, crystals of bicarbonate of soda (blasting soda) are fired at the stone or masonry to be cleaned. The crystals shatter and the energy released is transferred to the coating, which then breaks off. The process works from the outside in whereas conventional blasting removes the soiling in one fell swoop and can damage the stone or brick below.
Blasting soda is a soft material (the same hardness as talcum powder) so once the coating has been removed, it will not abrade the potentially delicate surface of your historic stone cleaning work or brick masonry .
Soda Blasting can be applied wet or dry and at variable pressures from 25psi to 160psi, allowing cleaning to be tailor made for each contract, thus producing the optimum finished results. Controlled surface preparation and metal cleaning achieves SA1, 2, 2.5 & 3 cleaning to provide maximum re-coating performance.
The uses of soda blasting in refurbishment projects are many and varied and can be applied to commercial and industrial buildings, as well as individual listed and historic properties. The sensitive nature of soda blasting makes it an ideal cleaning method for heritage sites and historical buildings where preservation is essential. We only use high grade soda that is suitable for use on listed buildings.
However, its applications are not limited to exterior masonry. The Eco Soda Blast System can uncover the charm of old interior walls, enhancing the aesthetic appearance of any room or as a method of preparing walls that are to be re-plastered.
We also specialise in cleaning surfaces that have been damaged by fire. Soda blasting will remove the black residue caused by fire leaving the substrate intact as well as effectively neutralising odours.
Masonry can become tarnished and unsightly as a result of pollution and general degradation over time, the versatile nature of our Eco Soda Blasting system means that it can be used for a large variety of applications.
