To Grind Or Not To Grind


Grinding is a very good way to get a concrete floor to the right profile for an epoxy coating. Grinding also saves time if you have a good vacuum system that will get all the dust off the floor. You then don’t have to wait for the floor to dry after rinsing and or etching. If you need to rinse the floor down to get rid of all the dust we recommend that you sprinkle some acid etching onto the floor and etch the floor while you are rinsing. Let the etch fizz for 5 or so minutes before you rinse. This way you are cleaning the dust and opening the pores of the slab a little more at the same time. But the main benefit of grinding is saving the drying time of a wet floor.
