If a mechanical removal method isn’t for you, try a chemical removal method. It is advised to wet grind, use a respirator, vacuums and HEPA filters in order to keep yourself safe. When using a mechanical removal method it is vital to take steps to control any dust that comes up so you are not exposed to too much silica. The benefit of using a mechanical removal method is that the grinding process can help to smooth any irregularities in the concrete below. Sanding- this is the process of using an electric sander to grind away any irregularities in a surface.Diamond grinding- a diamond grinder is a collection of closely grouped diamond saw blades.The Biggest difference between sandblasting and bead blasting is that bead blasting creates more of a smooth, satiny finish. Bead blasting- bead blasting is similar to sandblasting in that a bead blaster hits a surface with glass beads at a high velocity.Sandblasting- a sandblaster is a high-pressure air-powered gun that blasts sand at a high velocity against whatever surface you are trying to strip.The first is mechanical methods, these include: If your concrete coating has become discolored or if you’re just ready for a change, you can remove it in a variety of ways. Topical coatings- this includes paint, epoxy, sealers, waxes, urethanes, polyaspartics, and elastomeric/ waterproof membranes.Synergistic coatings- including acid stains, densifiers, dyes, curing agents, admixtures, and chemical, petroleum, and organic stains.Coverings- including carpet glue and tile thinset.Caps- this includes overlays, polymer-modified cement, and trowel-down epoxies.There are four distinctly different types of coatings, these include: The most effective removal method for your situation depends on what kind of concrete coating you have. If the bonds have been broken completely, the concrete coating will no longer provide a protective layer for the concrete. When a concrete coating’s bond to the substrate, the layer underneath the concrete, has been broken or weakened, it can result in the coating becoming discolored or foggy. They are manufactured with a steel wear stiffening band molded into the perimeter of the shroud for extra-long life and durability.If you have a concrete coating that wasn’t done correctly or that you don’t like anymore you may be wondering how to remove it.įortunately, you’ve got some options. U.S.SAWS dust shrouds are made with dual density, high wear, nonmarking polyurethane. The convertible shroud allows the operator to grind against a vertical surface. The lowered hose port increases maneuverability, lowering operator fatigue This simplified design is all one piece and secures to the grinder with a heavy duty stainless steel clamp that doesn’t require any tools to mount or adjust. The new shroud has more depth for longer life and more flexibility. With this dust shroud, concrete dust generated from grinding is extracted so that the operator may work without exposure to harmful dust. We took the classic dust shroud that we’ve been producing for over 20 years and made some adjustments for better dust collection and longer life. The 7″ Hub Shroud was designed to be the most durable and user-friendly dust shroud on the market.
