Concrete sandblasting is a technique that aims to blast away concrete to reveal the aggregate underneath it for a rougher finish on the surface. The abrasive concrete sandblasting technique has many applications and is often used for removing graffiti, dirt, paint and grime build up. It is possible to vary the degree of abrasiveness when concrete sandblasting to achieve specific results and textures. Professional sandblasting companies are able to perform work to get specific results and are capable of evaluating specific areas to get the optimal results and texture on a surface.

What you should know about concrete sandblasting

Over time, cement and stone can wear away to create inconsistent and visually unappealing textures. This often means the aggregate looks unattractive and requires restoration, both to restore the texture and the finish of the aggregate as well as to ensure its longevity. Restoring walls, columns, driveways, flooring and other areas usually require heavy-duty concrete sandblasting tools to get the right finish. Concrete sandblasting technique is usually the best and most efficient way to get the right finish, with no need for special coatings.

The process is usually necessary when stone aggregate is underneath the cement layer. Concrete sandblasting restoration aims to evenly expose the stone against the cement, this is both practical because it helps to refurbish surfaces, and more aesthetic.

Desired finishes are achieved by using abrasives which travel are impressive speeds at a surface, causing enough friction to wear away the uneven areas of a surface (or to remove paint, grime or dirt on the surface). The process requires a lot of skill and expertise – getting the right finish involves understanding the process and equipment involved properly. The abrasives and equipment used depend on the specific condition of your cement surface.

Before going ahead which a job some areas may require thorough cleaning, or even cutting to get the texture desired. Some companies will seek decorative finishes which requires the right level of skill and usually involves stencilling.

Professional companies can help you to achieve a smoother and more consistent surface, it is also far more efficient and often a lot more affordable than other surface restoration options, allowing a surface to be restored without the need for an entirely new layer of cement. The tools used in the process use abrasive materials blown at force to the surface to remove uneven areas, this helps to avoid damaging the surface in irreparable ways. It’s also a process that require minimal extra maintenance and only a small amount of preparation.

This is an excellent time-saving, cost-saving measure for those who want to create a perfectly even, non-slip surface.
