What Is Shot Blasting Concrete?
Shot Blasting machines concentrate these beads in one area at extremely high speeds to clear materials. Typically, this blasting method is used for metals and concrete, and it’s preferred for its surface preparation ability and environmental friendliness.
Shot Blasting Concrete works by using an airless, centrifugal wheel that propels blast media at a high velocity in a controlled pattern and direction. A blast wheel is accelerated at the concrete. Shot Blasting is a one-step preparation technique that removes laitance, paint, old coatings, dirt, and other contaminants and profiles the concrete surface all at once. It will not remove oil-ingress and water.
Shot Blasting machines propel thousands of shot beads as small as 1mm thick and up to 2mm thick over the surface of the floor to dislodge a thin layer of concrete. Once dislodged the loose concrete and shot beads are recycled back into the Shot Blasting machine, with the concrete dust going into an attached vacuum and the shot beads being recycled and used again in the same process.
Shot Blasting beads hit the concrete flooring at high pressure and speed in order to leave it in an optimal condition to then apply a new coating.
Shot Blasting machines are the professionals’ preferred solution for the cleaning and preparation of surfaces before applying a coating, paint, tiles, resin, ETC. It is completely Dust-Free with a high rate of removal, cost-effective & minimum downtime.
Captive Shot Blasting is very effective for the removal of concrete laitance, latex, old coatings, and contaminants, and for creating non-slip surfaces. The depth of the profile is variable allowing different textures from light abrasion to fully exposed aggregates depending on the floor specification.
Shot Blasting is a great way to prepare concrete floors for the application of line marking (to ensure the paint has a rough surface to adhere to) or to remove unwanted line markings.
However, it’s important to know that they can also be used on different types of floors, such as asphalt, concrete, and even steel.
