Although the Concrete Coatings Incorporated Spray-Tek™ Acrylic System is extremely durable, it is not indestructible. The rule of thumb is this: if it will scratch, chip or damage concrete, chances are it may damage the Concrete Coatings Incorporated Spray-Tek™ Acrylic System surface also. Exercise caution when setting heavy things on it. Take care not to drag heavy items that could scratch it. Periodic washing and sealing is all you should have to do to maintain the surface. Clean oil spills and the like as quickly as possible to keep it looking new.
