Patching Floor with Epoxy

July 18, 2017

Here is an outline of the procedure for patching with Epoxy.com Product #1 and Product #10.  Cold cure is identical but you should make even smaller batches and work even faster.

  1. Mix a small amount of the #10 (mix ratio 2A: 1B).
    1. Measure accurately and mix for 3 minutes with a proper size mixer.
    2. Typically very small batches less than a quart can be mixed with a stir stick.
    3. Larger batches should use a mixing paddle in a low speed drill or similar. Typically  mixing paddles are 5 inches or more in diameter.
  2. Apply a primer coat of #10 at a rate of 250-300 SF per gallon (typically done with a roller) to the substrate the mortar is to be attached to.
    1. Typically you will allow this to harden to the touch to make troweling into it easy.
    2. You can trowel into the wet primer in the case of small patches.
  3. Mortar Patch
    1. Mix another small batch of #10, using the methods in step 1 above.
    2. Add Product #82 Mortar Blend Aggregate to the mixed resin in 3a. You can add as much as 50 to 75 lbs. of mortar blend aggregate to a gallon of mixed #10 resin. If the material appears to wet you can add more, if it is too dry add less.
    3. Quickly trowel the patch into place.  Winter Cure Epoxy can set very fast in the bucket.
  4. Sealer Coat
    1. After the patch in step 3 has hardened, you can grind off any high spots and fill more material again if needed.
    2. Then seal the top of the patch.
  1. Product #10 is thinner than the #1, making it an excellent sealer for sealing up the patch.
  2. Alternately you can go directly to a very thin coat of #1
  1. Top Coat
    1. Mix small batches of #1 using the methods used in #1 above.
    2. Mix optional Antiskid fine into the coating above at a rate of 8-16 volume ounces of Anti-skid per gallon of mixed resin.  12 ounces per gallon is typical.  This is done by mixing the resin first, adding the anti-skid and mixing for another min.
    3. Quickly apply the material with a roller at a rate of 160-200 SF per gallon per coat.  Two coats is recommended.
  2. Please read all the information below before starting your project.

Surface Preparation is the most critical portion of any successful resinous flooring
system application. All substrates must be properly prepared as outlined in Epoxy.com
Surface Preparation Procedures..

MIXING INSTRUCTIONS

  • Mix only that amount of material that can be used in a two hour period. In hot weather,
    plan work for the cooler times of the day.
  • If using less than full units, proportion the amounts carefully and mix for 2-3
    minutes using a low speed drill, scraping the bottom and sides of the mixing vessel.
    DO NOT ADD WATER.

APPLICATION

  • Apply Product #442 polyurethane at a spread rate of 275-300 square feet per gallon
    to achieve 2.0-2.5 mils dry. Thicker application may result in bubbling in the cured
    film.
  • Recoat time is approximately 10 hours at 77°F.
  • Keep a wet edge at all times.
  • Apply Product #442 ESD at a spread rate of 160 square feet per gallon to achieve
    5 mils dry.
  • Use with adequate ventilation.
  • Read material safety data sheet before using.
