Concrete Sandblasting
Delivering Excellence in Surface Preparation and Restoration
Concrete Sandblasting Services in Sydney
Concrete sandblasting can be used to assist on a variety of concrete projects. A highly effective method of removing surface contaminants such as paint, coating and sealant, sandblasting (or abrasive blasting) is also the ideal preparation solution for concrete surfaces. The abrasive blasting process is applied to the concrete area to coarsen or texture the profile, allowing the application of protective coating to sufficiently bond to the surface. In addition, our sandblasting methodology is used to further expose surface aggregate.

The Concrete Sandblasting Process
Typically, when it comes to sandblasting a concrete surface, our clients specify either a light, medium, or heavy sandblasted finish, depending on the desired level of aggregate exposure.
Initially, we need to check, control, and eliminate any potential work hazards. This includes clearing the designated sandblasting area of any pedestrians, vehicles, or contractors currently onsite, as well as preparing and containing the environment by masking or taping surrounding surfaces.
This is all to prevent unnecessary harm or damage to surfaces or individuals in the vicinity where the concrete sandblasting will be conducted.
When we sandblast in an enclosed area such as a factory or a warehouse, we make sure there is sufficient ventilation.
If we’re using stencils to achieve a particular pattern design, we ensure to fix them to the surface before blasting begins.
We begin with a 1 m² test patch, by sandblasting the concrete surface from a distance and at a relatively low pressure of 70psi – 80psi. Then we gradually increase blast pressure towards 100 psi, thereby increasing concrete aggregate exposure until the desired finish has been achieved.
We proceed by replicating the achieved finish throughout the remaining allocated surface area requiring abrasive treatment and aggregate exposure.
Once completed, we ensure the surface area is vacuumed, swept, or blown down, and the produced waste and abrasive are disposed of appropriately.
Safety is paramount, therefore we ensure our technicians are wearing a protective Air Helmet, a hooded blast suit, gloves, earplugs, and steel cap work boots.
Benefits of Sandblasting Concrete Surfaces
There are numerous advantages to be gained from choosing sandblasting to add texture to a concrete surface. These benefits include:
It’s a cost-effective choice compared to alternate methods
Offers an unparalleled coarse finish, by alternatives
It’s highly efficient, being able to treat up to 100 m² a day per operator
