Why Prepare a Surface?
Most coating adhesion problems are not the fault of the coating, but the result of poor surface preparation. Two conditions must be met before any coating can achieve a good bond with a concrete floor. First the surface must be chemically clean of dirt and other contaminants. Because it is porous, concrete will hold chemicals, oils, fats or other penetrating substances that can act as barriers and prevent coatings from sticking properly. All these contaminants must be removed before applying a coating. Secondly, the surface must be given a mechanical etch or profile. Surface profile can be described as the miniature ridges and valleys that give concrete the "teeth" to form a successful bond to the coating. Without a good profile as a base, the chances of coatings becoming chipped or breaking up altogether are significantly increased and the life expectancy of the floor is reduced.

Interstate Concrete Coatings "shot blasts" every floor before coating application in order to achieve a nice surface profile. Shot blasting is a "one step" method that strips, cleans and etches all at once. It leaves the surface dry and chemically free without generating dust pollution and it totally eliminates any drying time required before coatings can be applied.
