Over the years, wear and tear causes an inconsistent ratio between the stone and cement ratio of concrete. The result is often an under-exposed aggregate.
The restoration of concrete to its original condition, therefore, requires a heavy blast removal of cement in the built-up areas and a whip blast to achieve an exposed aggregate concrete finish.
From concrete patio walls and columns to concrete driveways, floors and sandblasting paint off concrete, sandblasting is one of the most effective ways to restore your concrete for a non-slip and coating-free solution.
Sandblasting concrete is generally required when stones are buried beneath the cement. The restored finish should, therefore, see stones being exposed to achieve a rough texture and an even ratio of cement and stone. This is what makes ProStrip Sandblasting’s abrasive blasting media perfect for refurbishing concrete surfaces to the desired concrete finishes.
During the sandblasting process, the abrasive material travels at a high enough velocity to generate friction on the concrete surface being prepared.
However, having a concrete surface restored back to its original condition also requires particular procedures and industrial sandblasting equipment, as the degree of blasting depends on the current condition of your concrete.
While certain sections of the concrete surface may require a light cleaning, other parts may require deep cutting to achieve the desired textured concrete finishes.
Any abrasive blasting tool can be used for light blasting, however, with control over the equipment media and pressure, our high performance sandblasting equipment is able to produce a range of cut depths to the concrete in question. With the use of stencils, we also offer distinctive decorative patterning for further sandblasting needs.
ProStrip is Melbourne’s leading specialists in sandblasting exposed aggregate concrete – an ideal solution to restoring worn and torn concrete, and relayering new concrete.
There are many sandblasting techniques available when it comes to concrete. These include:
- Exposed aggregate
- Non-slip applications
- Removal of unwanted coatings such as paint, dirt, oil or undesirable chemicals
