- metal - removal of old coverings, scales, rusts, preparation of a surface before drawing a sheeting;
- brick, concrete, stone - removal of the destroyed and defrozen sites at repair, and also before coloring, grinding of floors.
Advantages of abrasive powder before sand
Quartz sand, other things being equal specifications, badly profiles a surface, unlike other abrasives. Quality of cleaning at the same time is reached not above Sa 2 ½, and the consumption of sand and productivity of works by 2-4 times concedes to slag abrasives.After works as quartz sand on the cleared surface there is a melkodispersionny dust in number of 70-75% which demand cleaning, so additional expenses. For the same reason cleaning with sand does not provide sufficient coupling of a covering with a surface as presence of dust on a surface breaks adhesion.
Besides quartz sand has a feature - it zabelivat corrosion spots. It is impossible to see it with the naked eye, and the nonprofessional about this effect does not even know. The paint applied on such surface begins to bubble at once, there is a subfilm corrosion which quickly enough will lead to destruction not only coverings, but also the painted design.
