Shot Blasting Concrete

Shot Blasting Concrete: What do I need to Know?

Professionally shot blasting your concrete can be an affordable way to add value and longevity to your work. As a result, it’s becoming an essential part of many projects. But with so many variables to consider, it can be difficult to know where to start. So, what common questions are we asked about shot blasting concrete floors and walls and what can we do to help finish out your project correctly?

What is shot blasting concrete?

Shot blasting allows you to fully prepare a concrete surface for use, restore wear and tear, and to carry out a number of site-specific tasks. These might include surface preparation, re-texturising, decorative and other options. It’s a vital part of the treatment process.

What industries typically need to shot blast concrete?

It’s not just the construction industry that can make use of shot blasting. It can be used in any industry that uses, prepares and manages concrete. This could include decorative industries, industrial experts, and any business that needs to regularly clean or prepare its products, flooring, or concrete walls.

What machinery can be used do this?

Shot blasting is carried out through a range of devices from large vehicle mounted units to held-held devices. While these may vary based on the end goal and user, the most common units often prove to be portable single-user devices that are flexible enough to carry out a range of tasks.

What materials are used?

There are a number of different materials that can be used for the shot blasting process, including steel and stainless steel shot and grit, aluminum, garnet and walnut shells. The choice of material will depend on the specific job it’s required to do, with some harder and more abrasive than others. The choice is often dependent on location of the surface and the ability to contain the abrasive material.

What are the pros and cons of the shot blasting process?

The abrasive materials used have an aggressive action on the surface of the target material, and the powerful action can remove contaminants from the surface of the concrete. It’s a quick way to remove contaminants, and it doesn’t require complex machinery for the process.

It’s not fit for smooth surfaces, and if the abrasive is used too regularly then it would eventually wear away the surface of the target material. Lots of heat and emissions from the surface and abrasive are generated, which can present a range of health and safety challenges. As a result, a considerable number of precautions are required if it’s to be used safely.

Do you need training and expertise to do this?

While training and guidance will ensure a quality finished product, there is no qualification or specific training required to operate a blasting unit. However, it is vital that you are fully insured to carry out the work, that your project has been fully planned, and that you approach the task with the utmost respect and caution.

What can happen if shot blasting is not done correctly?

Failure to properly prepare, or to undertake the task correctly can result in damage or a poor-quality finish. As with other types of industrial machinery, incorrect use can even result in injury or worse. Shot blasting uses propulsive force to expel material that can be highly inefficient and even dangerous if not applied correctly. This makes it essential to find a professional provider and guidance that works for you.

Any instructions or tips on shot blasting?

When it comes to shot blasting concrete, it is essential to take an informed approach to your project and ensure that you find the right tools for the job. This means choosing the correct grade of shot, unit, and provider to supply materials to help you get the job done safely and to the best of your ability.
