How To Acid Etch Concrete
Acid Etching Instructions
Proper concrete etching is a REQUIREMENT for all Sani-Tred floor installations on the original surface. The procedure for how to etch concrete MUST be followed exactly as specified below for proper installation. Sand blasting, captive ball blast or scarifying the concrete floor surface is always preferable to acid etching when ever possible.
Detailed Acid Etching Instructions
The purpose for acid etching is to remove “latencies” from the surface of concrete floors. When a floor slab is poured, contractors etc often float or trowel the surface smooth by working up a smooth weak film over the concrete surface, this weak film is called “latencies”. Latencies can be removed many ways, see Technical Information for Concrete Floor Preparation
Never acid etch concrete walls, unless the concrete was troweled by hand. Acid etched concrete floors will provide an approved surface in which to produce a penetrating and permanent bond for the Sani-Tred products. While this treatment is effective on new concrete, it may not be completely effective on old concrete with oil, grease, fats, or other bond-breakers present, unless it is properly prepared. If oil contamination exists see Technical Information for Oil or Grease Contamination. Before any floor coating is applied to concrete, remove ANY previous applied products, sealers, contaminants, bond breakers, etc... The concrete should always be prepared properly in order to allow a penetrating and permanent bond of the Sani-Tred products. The bond, durability, and service life of any floor surface material relies on proper concrete surface preparation. Previously applied paints or coatings may usually be removed using our “Off The Wall Coating Remover” which is available from Incredible Products LLC, then washed and acid etched. Other methods of preparation: see Technical Information for Concrete Floor Preparation.
