Cleans and etches in one step, bland odor Cleans and prepares concrete, masonry and brick for coating, staining or sealing Ideal for cleaning, degreasing and acid etching concrete floors, walls, basements, driveways, swimming pools, patios and containment areas prior to coating, staining or sealing Water-based, biodegradable, non-flammable, non-toxic and non-abrasive Coverage area 200 sq.ft. per quart or 800 sq.ft. per gallon Concrete clean and etch is ideal for cleaning, degreasing and acid etching concrete floors, walls, basements, driveways, swimming pools, patios and containment areas prior to coating, staining or sealing. Safer and easier to use than muriatic acid, it creates a porous surface, and provides the even profile and uniform appearance preferred for clear coating applications. It can also be used to remove efflorescence (alkali salts) and to neutralize new concrete and new mortar joints on cinder block, masonry and brick. Directions for use: Mix 1/3 gal of concentrate with 1 gallon of water in a plastic sprinkling can. 1 gallon of concentrate will produce 4 gallons of premix; sufficient to cover 800 square feet. Hot water will accelerate cleaning and etching. Sweep the surface to remove loose debris and scrape off excess grease and oil. Cleaning a 10’ x 10’ section at a time, dampen the surface with a fine spray of water and using the sprinkling can, apply the premix evenly over the surface. Scrub the premix into the surface with a stiff bristled broom until the foaming stops. Note: if no foaming occurs, surface has been previously sealed and this will prevent penetration of premix. Remove the sealer and reapply krud kutter concrete clean and etch premix. Triple rinse the surface with a water hose. Scrub while rinsing to ensure removal of all loosened material. Allow the surface to dry thoroughly before applying stain or sealant. After the surface has dried, check any glossy or oily areas by applying a few drops of water. If water does not penetrate quickly, re-etch the affected areas. Contains: Phosphoric acid in a water-based solution. Caution: Eye and skin irritant.
