Concrete Clean & Etch - Directions for Use


Mix 1 quart (32 oz.) of concentrate with 3 quarts of water in a plastic sprinkling can. This will yield sufficient premix to cover 200 sq. ft. Hot water will accelerate cleaning and etching.

Sweep the surface to remove loose debris, and scrape off excess grease and oil.

Cleaning a 10 ft x 10 ft 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 & ETCH premix.

Triple rinse the surface with a water hose. Scrub while rinsing to insure 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.

Caution:  Contains phosphoric acid. Eye and skin irritant. In case of contact with eyes or skin, flush with water for 15 minutes. If irritation persists, seek medical attention. If swallowed, take large amounts of water. Do not induce vomiting. Get medical attention. KEEP OUT OF REACH OF CHILDREN.  24 HOUR MEDICAL EMERGENCY: CHEMTEL (800) 255-3924
