Coverage: Coverage will vary depending on density, porosity, texture, surface absorption, weather, time solution left on the surface and application method. Used as directed, HDAC will cover approximately 1,000 - 2,000 square feet per gallon (90 - 185 square meters per 3.785 liters) with standard dilution.

Application Instruction

Thoroughly wet the surface to be cleaned with clean water. HDAC may be applied with a clean mop or acid resistant brush. Dilute HDAC with water. Start with 1 part HDAC and 20 parts water. For stronger solutions reduce the water down to as low as 3 parts. Allow HDAC to sit on the surface for 1 - 5 minutes while agitating with a brush. Do not allow HDAC to dry on the surface. Work small areas. Extract all dirty remains with a wet vacuum system. Multiple applications may be necessary. After extracting HDAC solution, rinse thoroughly with clean water. Once surface is complete, rinse areas with Tile & Stone Cleaner and clean water (20 - 1) as directed.

If a non-acid deep cleaning is necessary, use Liquid Poultice as directed.

Special Notes:

Acid and the vapors, no matter how mild, may etch, lighten or alter the color of tile, cementious and natural stone surfaces. Repeated acid washing may damage some surfaces. Avoid contact with all metals

Do not mix with ammoniated cleaners as harmful fumes may result.

Heavy Duty Cleaning: Use Phosphoric Acid Cleaner , HDAC or Liquid Poultice as directed.

Light Cleaning: Use Tile & Stone Cleaner, Porcelain & Ceramic Tile Cleaner, Limestone/Travertine Soap or Counter Kleen as directed.
