      How-To Guide

      Safety Precautions

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

      Disclaimer: Direct Colors does not warranty or guarantee results. Variations in concrete or improper application may result in unintended outcomes. Always test the product on a small, inconspicuous area and allow it to fully cure to ensure compatibility and desired results.

      Step 1: Preparation

      General Precautions:

      • Cover areas at risk of over-spray using a plastic drop cloth.
      • Ensure newly poured concrete has cured for 15 days before application.

      For Existing Concrete:

      • Remove paint or previous sealers with Soy Gel Stripper.
      • Eliminate carpet glue or other adhesives with Bean-E-Doo® Mastic Remover.
      • Clean off any oils, dirt, remnants of Soy Gel Stripper, or Bean-E-Doo® Mastic Remover using a scrub brush or floor scrubber paired with ProClean Degreaser™.
      • Test absorption by pouring water in different areas. If it doesn’t absorb within five minutes, etch the surface using CitrusEtch™. If you use CitrusEtch™, neutralize with ProClean Neutralizer™ and rinse thoroughly.

      Step 2: Mixing

      • Select either a birdcage mixer or a double-box mixer for the mixing process.
      • For the standard 40-pound batch, start by pouring 3.5 to 4 quarts of water into a clean five-gallon bucket. For the smaller 2.5-pound batch, use 1 cup (8 ounces) of water instead.
      • If pigment is part of your mix, thoroughly blend it with the water before adding Patch-Rx™ Concrete Repair. Make sure to reach the bottom edges of the bucket with the mixer to incorporate any pigment that has settled. 
      • Gradually add the Patch-Rx™ Concrete Repair to the bucket, mixing continuously until you achieve a uniform and thoroughly combined mixture. 

      Step 3: Application

      General Note: Coverage is approximately 80 sq ft per 40-pound box for a skim coat of 1/16th of an inch. For a 2.5-pound box, the coverage is approximately 5 sq ft for the same 1/16th inch skim coat. Adjustments might be needed based on concrete texture, surface porosity, and application method.

      Carpet Tack Holes & Divots:

      • Achieve a peanut butter consistency by mixing Patch-Rx™ with water.
      • Use a putty knife or trowel to fill divots, ensuring the surface is smooth.
      • After drying, sand excess areas using 80-grit sandpaper.a
      • Vacuum the debris and clean any residue with a damp towel.
      • Allow to cure between 11-24 hours before proceeding with colorants or sealing.

      Hairline Cracks:

      • Clean the cracks of dirt and debris using a leaf blower or air compressor.
      • Prepare a mix using the standard ratio of 40 lbs of Patch-Rx™ with one gallon of water. For the 2.5 lb size, adjust the water quantity proportionally (that would be 1/16th of a gallon or roughly 8 oz of water for 2.5 lbs of Patch-Rx™).
      • Use a trowel or putty knife for application, smoothing the surface.
      • Once dry, follow the same sanding, vacuuming, and cleaning process as above.
      • Allow it to cure for the same duration before proceeding.

      Tips & Tricks

      • For extended working time, mix Patch-Rx™ with ice-cold water.
      • When including pigments, maintain a consistent ratio for Patch-Rx™, pigment, and water to avoid variations.
      • On surfaces exceeding 90 °F (32 °C), mix with ice-cold water to improve workability.


      Ensure tools are cleaned with water before the Patch-Rx™ mixture dries. Familiarize yourself with the drying time to avoid difficulties during cleanup.

      Tools & Supplies

      • Squeegee Trowel or Putty Knife
      • Drill Mixer
