Surfaces which we recommend should not be cleaned with SodaBlasting.

While we'd love to be able to tell you that we can solve all your cleaning problems, there are certain things that cannot be cleaned to an adequate standard or without causing damage to the substrate:

Stamped concrete surfaces, SodaBlasting removes the protective varnish coat that is normally applied to the concrete; excess pressure can also remove thin or uneven paint finishes (unless of course this is the purpose of the cleaning)

Internal property walls where there is extensive landscaped garden; due to the pH of the Soda this may result in plant leaf burn or even root burn if the Soda is washed off into the plant beds. On small area flushing with water can be sufficient to remove and neutralize the effects of the Soda. This is site specific, so if you are considering this give us a call, we'd be happy to give provide you with advice

Extremely porous surfaces which have oil or solid stains; in cases like this the stain has in most likelihood penetrated deeply into the material, Soda may not be sufficient to remove this; this is case specific

Deep rust marks; while Sodablasting is able to remove surface rust on most surfaces, it cannot compare to abrasive blasting for “deep cleaning” of old or penetrative rust patches

Stained wooden surfaces; wood is permeable until treated, any colour stains applied to the wood are drawn into the fibres of the wood. Sometimes the wood is then sealed; sodablasting will remove the varnish, but will not remove the stain from the wood. In most cases only deep sanding will remove stain from untreated wood.

Certain wooden surfaces; wood as you may know has two types of wood; a dark hard layer (formed in winter) and a pale soft layer (formed during summer and spring). The alternating layers therefore have different densities and as such differing resistances to abrasives; in addition faster growing species such as Pine are generally softer than a slower growing tree such as Mahogany is. Removing varnish from wood is a delicate affair, whilst SodaBlasting will remove the surface layer of varnish or oil; it may also remove softer layers of wood that lay below - resulting in ridges. This can normally be remedied by sanding afterwards to restore a flat surface, in many cases the wood would have had to have been sanded to this depth to remove the coating or varnish layer. This is case specific and normally a small test patch on the reverse surface can quickly establish the viability of the undertaking. See above Stained wooden surfaces

Asbestos; we do not and will not advocate the sodablasting of any asbestos substrates (blue or white) due to potential environmental and health risks caused by the blasting process
