How-To Guide

Printable Patching Compound How-To Guide

Step 1: Preparation

  • Cover areas at risk of over-spray with plastic drop cloth.
  • Newly poured concrete must cure for 30 days before application.
  • For existing concrete:
    • Remove paint or previously applied sealer using Soy Gel Stripper.
    • Remove carpet glue or other adhesives using Bean-E-Doo® Mastic Remover.
    • Remove any oils, dirt, debris, Soy Gel Stripper, or Bean-E-Doo® Mastic Remover using scrub brush and ProClean Degreaser™.
  • Verify absorption by pouring a cup of water in various areas. If not absorbed within five minutes, etch surface with CitrusEtch™.

Step 2: Application

Coverage rate is approximately 75 square feet per 50-pound box when applying a skim coat (thin coat). Coverage rates may vary based on concrete texture, surface porosity, and application method.

NOTE: When applying on surfaces over 90 °F (32 °C) use ice-cold water when mixing Patching Compound to increase working time.

Caution: May be harmful if swallowed or ingested. Contact with skin can cause mild irritation. Avoid contact with eyes.


  • Pour 4.5 - 5 quarts (4.3 - 4.7 liters) of water into a clean 5-gallon bucket.
    • If using Concrete Pigment, mix into bucket until thoroughly blended (otherwise streaking will occur).
  • Slowly pour 50-pounds of Patching Compound into bucket while continuously mixing with a drill mixer.
    • Use a birdcage or double box mixer attachment.
    • Mix for at least three minutes to make sure water and Patching Compound have thoroughly combined.
  • Patching Compound must be applied within 30 minutes (otherwise product hardens and cannot be used).


  • Carpet Tack Holes & Divots:
    • Mix a small batch of Patching Compound and pour enough to have a little material spillover.
    • Trowel Patching Compound flush with concrete surface.
    • Let cure for at least six hours.
    • Once cured, sand any overage away with 80 grit sandpaper.
    • Sand down flush with 120 grit sandpaper.
    • Vacuum up the debris with a shop vac.
    • Wipe any remaining residue up with a damp towel.
    • Allow to cure for 11-24 hours before proceeding with Overlay application.
  • Hairline Cracks:
    • Using a leaf blower or air compressor, blow out all cracks of dirt and debris.
    • Spread out dry Patching Compound powder along the cracks.
    • Use a broom to pack dry powder into the cracks and sweep up excess powder.
    • Using a pump-up sprayer, saturate the cracks with water.

Pro Tips:

  • Let cure for at least six hours to allow the moisture to evaporate.
  • Proceed with Overlay application.
  • If using integral pigments in your mixture, you must measure your Patching Compound, pigment, and water quantities to be the same every mix; otherwise, you will have color variations across your project.


  • Clean tools and supplies using ProClean Degreaser™ and warm water before Patching Compound has cured.
  • Clean tools and supplies with mechanical sanding or a concrete dissolver after Patching Compound has cured.

Tools & Supplies:

  • Pump-up sprayer
  • Scrub brush, cotton mop, or low-speed floor buffer with brush attachment
  • Wet-dry vac or mop bucket
  • Squeegee trowel
  • Plastic drop cloth
