However thick an epoxy coating might be, primary surface adhesion is all that holds it to the floor. This is as true for aggregate based systems as it is for thin-mil coatings. The video documents an epoxy terrazzo floor that has delaminated. While most the floor is soundly attached, the section being repaired here has failed. The process done includes removal of the failed section, surface grinding, Shotblasting and new terrazzo flooring installation. ?????????? #EPOXYTERRAZZO #SURFACEPREPARATION

Concrete grinding produces dust that will act as a bond inhibitor. This is only a problem if the dust is not removed. Wand vacuuming does a good job to collect most of the dust. For a surface free of all grinding dust residue, Shotblasting is one way to achieve this ideal condition. The video documents a concrete floor that’s been ground and wand vacuumed. After this, a shotblaster is used to fully de-dust the floor. Once the magnet sweeping collects all loose shot, a Polyaspartic primer is applied as a skim coat. ?????????? #SHOTBLASTER #SURFACEPREPARATION

Concrete grinding does a good job to remove coating residues and flatten concrete. Once complete, the fine dust is often packed into the slab’s pores. Wand vacuuming will capture most the dust, but some will remain. A shotblaster, moved more quickly than is standard, will fully de-dust the floor. The video documents a floor that’s been diamond ground and vacuumed. Before applying a water based primer, a shotblaster is passed over the surface to extract all dust. ?????????? #SHOTBLASTER #SURFACEPREPARATION

Comprehensive surface prep should leave a concrete slab profiled and absorbent. To attain maximum surface adhesion and fully hold a broadcasted flake, enough resin should be used to act as primer and body coat. The other option is two separate coats (primer then body) but one coat is faster. The video documents a slab once covered by a DIY coating. After diamond grinding, a shotblaster is used to remove all fine dust. Then a Polyaspartic is applied to prime the slab and hold the flake. Once cured and scraped, a Polyaspartic topcoat is applied. ???????????????????? #SURFACEPREPARATION #POLYASPARTIC

Heavily trafficked concrete often breaks down wherever abrupt elevation differences or voids are present. It’s not much different than what happens to make a pothole worse. What starts as an open joint or small divot quickly becomes a forktruck damaging surface hazard. Continued neglect will only lead to more damage; both for the floor and the equipment that uses it. The video documents patching of a forktruck aisle that has become damaged by use. The process begins by removing all broken concrete and ends with replacement using high performance coating products. ???????????????????? #SURFACEPREPARATION #INDUSTRIALFLOORING

Excess grinding dust is a liability when trapped between a resinous primer and concrete. While most resinous floor coatings have a threshold for some dust being present, any amount will adversely affect maximum surface adhesion. Since diamond grinding is often a required step to prepare a concrete floor, its byproduct dust is a contaminant that’s best addressed by Shotblasting. ?????????? #SHOTBLASTER #SURFACEPREPARATION

Shotblasting to remove fine grinding dust also treats where the grinder couldn’t reach. Cracks and pits are cleaned of dust and dirt that would otherwise hinder a coating’s ability to bond. While most patching products have great resiliency and abrasion resistance, sound surface attachment ensures the patch stays put. With regard to leftover grinding dust, a byproduct of shotblasting is a dust free floor. ?????????? #SHOTBLASTER #SURFACEPREPARATION

Fine dust produced by diamond grinding gets stuck in a slab’s pores. Aggressive wand vacuuming can help to recover most of this dust, but there is usually some residue that remains. Shotblasting, as a byproduct of the process, leaves the floor dust free. ?????????? #SURFACEPREPARATION #SHOTBLASTER

Rough concrete can be ground smooth. But what about the elevation change that results from a surface being reduced to its lowest pit’s depth? What’s left is a low spot sometimes referred to as a “bird bath”. In instances where surface spalls and divots exist, Shotblasting might be the best option. Though it doesn’t smooth the surface, it removes the dirt and opens the concrete’s pores. Then the damage can be patched and subsequently ground. The result is a smooth surface that’s likely to resemble its original intended flatness. ?????????? #SHOTBLASTER #SURFACEPREPARATION
