What is concrete sandblasting?

Concrete sandblasting is an abrasive blasting process used to remove concrete to reveal the aggregate below for a rough surface finish.

This method is also useful for removing graffiti and other splatters of paint, dirt, and grime in a flash.

Finding a company with a team of concrete sandblasting experts with extensive experience in assessing textured surfaces and determining the appropriate level of abrasiveness is a great way to refinish the surface of your concrete. A reputable company and team will help create a highly effective and efficient reconditioning action plan.

Concrete’s stone-to-cement ratio changes over time due to normal wear and tear. In many cases, the consequence is an aggregate that is not properly exposed.

A powerful blast of cement removal in the built-up regions and a whip blast to obtain an exposed aggregate concrete finish is consequently required to restore concrete to its original state.

This method is ideal for concrete sandblasting paint and coating off concrete, as well as concrete patio walls, columns, driveways, and floors for a slip-resistant and coating-free surface.

Concrete sandblasting is usually necessary when stones are buried under the cement’s top layer of cementitious material. A rough texture and an equal ratio of cement and stone should be achieved in the restored finish. The right abrasive blasting media will help you achieve a great look and concrete surface finish.  

Concrete sandblasting uses high-velocity abrasive material to create friction on the concrete surface being prepped before it is blasted.

Although the degree of blasting required to restore a concrete surface to its previous state is dependent on the present condition of your concrete, special processes and industrial sandblasting equipment are also required.

To create the required textured concrete finishes, certain areas of the concrete surface may just need a minor cleaning, while others may have a significant amount of deep cutting.

Our high-performance sandblasting equipment is able to provide a wide variety of cut depths to the concrete in question by controlling the machine media and pressure. Stencils allow us to create unique ornamental patterns for a variety of sandblasting applications.

Exposed Aggregate via concrete sandblasting

Sandblasting the concrete

Sandblasting exposed aggregate concrete is a great way to restore damaged or torn concrete and to relayer fresh concrete.

When it comes to concrete sandblasting, there are a plethora of options. These are some examples:

Patterns that are aggregated

Non-slip software

Paint, grime, grease, and other unpleasant substances may all be removed from the surface.

What are the benefits

Sandblasting concrete instead of typical surface repair treatments has a number of advantages:

  • Compared to traditional processes, it guarantees more uniform concrete finishes in the uniformity of the cement and stone ratio.
  • The expense of tearing up the concrete, disposing of the waste, and then installing a new layer of concrete is much more than the time and money saved by sandblasting.
  • For an exposed aggregate, the method employs compressed air to project abrasive material at the concrete. This prevents the surface from being permanently damaged.
  • Concrete may be restored to its original state with, which requires very little preparation before further treatment.

When it the best time to sandblast?

When sandblasting concrete, let it to dry for at least one day before beginning, as this will expedite the process and give you the greatest chance of having an evenly distributed aggregate exposure.
