Concrete Surface Preparation

Shotblasting: Shot blasting is a method of concrete surface preparation to allow for the creation of a surface profile for the installation of any epoxy or polyurethane coating/overlayment. Shot blasting is a self-contained machine that uses small ball peen metal abrasives which are propelled at high velocities towards the substrate. The shot blast machine is attached to an industrial H.E.P.A. filter, dustless vacuum, where 85% of the shot is recycled and separated from the dust particles which enter the vacuum for later disposal.

Diamond Grinding: Is another method of concrete surface preparation. This method is done by either a 7”, 17”, 24” or 36” grinder that has a diamond metal blade head/s that remove the top layer of concrete from the surface creating a surface profile. These machines are also connected to an industrial, H.E.P.A filter, dustless vacuum that contains 95% of all dust that is created from grinding. There are many debates about which surface prep method is superior, and there is no right answer. Both methods are exceptionally good in achieving a surface profile for coatings to bond to, it just all depends on the dynamics of the job and the specification of which coating is being installed.
