Our main form of preparation is diamond-bit grinding with our dust collector system , which extends the life of your floor by giving you the greatest adhesion possible. The use of course grit diamonds or polycrystalin diamonds help us achieve the required profile. Our diamond grinders consist of three rotating heads. By varying the grits and bonds used, diamond grinders can be affective on differing concrete types. Diamond grinders are especially helpful when cracks or joints are at different profiles and need to be leveled. This is the number one form of preparation used in the coatings industry today. The use of hand grinders for edges and other small areas combined with our dust collector system make for very dust free site.
Blastrac Walk-Behind Shot Blasting Systems this preparation is used mainly to remove old coatings. It uses a high performance, airless, centrifugal wheel for propelling blast media at a high velocity, in a controlled pattern and direction.
Metal abrasives, thrown by the rapidly rotating blast wheel, are accelerated toward the surface being prepared. The media strikes the surface and rebounds, along with the removed contaminants, into a recovery chamber or separator. The dust collector removes pulverized abrasives, dust, and contaminants. Very little abrasive is lost and the usable media is returned to the storage hopper for recirculation by the blast wheel.
Different surface profiles can be achieved by varying the shot size, shot flow rate, and machine travel speed. Shot blasting produces the most course profile while removing any deteriorated or weak concrete, leaving the surface immediately ready for coating.
