Why do Floors need to be Prepped?
In order to properly coat any concrete surface, whether it be with an epoxy, polyaspartic, or polyurethane coating, the floor needs to be properly prepped. If a concrete surface isn’t sufficiently ground and repaired prior to laying down a coating there is a strong possibility that the coating will bubble, peel, flake off, not cure properly, or fail to adhere to the surface altogether.

The Grinding Process
Grinding will ensure that the floor is clean and ready to bond to any coatings that may be applied. The appropriate concrete surface profile must be achieved to ensure that the products can bond to the concrete effectively. In many cases, most floors can be properly prepared for coatings with industrial concrete grinders, as this will both clean and level the floor out sufficiently for a coating to be applied.
Our diamond grinders are equipped with a variety of diamond tooling, whether these be varied grits of hard and soft bond tooling, or PCD diamond tooling that are made with the express purpose of removing coatings such as epoxy.

Shot Blasting vs. Grinding
If the concrete flooring has any damage – such as cracks, pitting, gauges, or pinholes – it will be repaired and treated with a poly-based system, and then ground and blended into the existing concrete to ensure everything is smooth and level before the coating is applied. Given that epoxy and polyaspartic coating systems are liquid based, in many cases they will self-level and fill in minor pinholes or scratches. However, they will not effectively fill in larger areas with deep cracks or pits, and so these areas will need to be repaired before any coating is applied. In the case of concrete polishing, the concrete will still need to be repaired prior to further grinding and polishing to ensure the final product is smooth, level, and without blemish.
