Concrete Surface Preparation Profiles for Overlay or Restoring Existing Concrete Proper surface preparation of existing concrete is essential for achieving a successful project including resurfacers, polymer-modified or self-leveling overlays, sealers, coatings, or stains. Since there are many
With the concrete sound and contaminant-free, all that’s left is to adequately roughen the surface, but to what degree? The blasted concrete surface is too rough to be measured by tape and quantified in microns or mils. The most effective reference tool for determining concrete surface profiles is the molded rubber comparator chips, available from the International Concrete Repair Institute.
Mar 01, 2010· Surface failures like this are one of the most common ailments with concrete, whether caused by freeze-thaw action, aggregate popouts, or corroded reinforcing steel. Many surface failures on concrete slabs are little more than cosmetic—the concrete remains functional but looks bad or has a chalky surface.

Blasting opens the pores and roughens the surface, providing an interface for the patching material. Impact tools used to remove unsound concrete cause extensive microcracking. Patching a surface weakened by microcracking defeats the purpose of the repair. Abrasive blasting is the preferred method to remove the microcracked surfaces.
Slick Troweled Concrete is created when a steel hand trowel or machine is used by the cement mason to close the exposed surface of the concrete project. Typically, slick troweled concrete can be found as garage floors, basement floors, warehouse floors and covered front porches.
Concrete can deteriorate for a variety of reasons, and concrete damage is often the result of a combination of factors.
