When not to use EPOXYShield


Sealed concrete — Determine if there is a concrete sealer present by dripping a small amount of water onto the surface. If the water beads, a sealer is present and paint may not adhere properly.

Poorly-bonded previous paint — If the floor is previously painted, remove any loose paint by sanding and scraping. Test the adhesion of the remaining paint on the surface by doing the following:

1. With a single-edged razor blade, cut an X through the coating and down to the concrete.

2. Apply a 4 piece of duct tape over the X and press firmly.

3. Completely remove the tape with one quick pull.

4. If more than 25% of the taped area is removed with the tape, the original coating is not adhering well, and the floor should not be coated with EPOXYShield unless all previous paint is removed.

Moisture in the concrete — Apply a 2′ x 2′ sheet of plastic (such as a heavy-duty garbage bag or 1 gallon plastic storage bag) to an area of the garage floor. Tape down the edges with duct tape and allow to set for 24 hours. If water droplets appear on the inside of the plastic or if concrete appears wet (darker in color), moisture is trapped in the concrete and the floor should not be painted.

Loose or poorly cured concrete or concrete dust — If the concrete is loose, chipping (spalled), or has concrete dust present, the coating will not perform properly unless all loose material and dust is removed and damaged areas repaired.

Apply when air (ambient) temperature is 60-90:F and relative humidity is below 80%. Concrete floors take a long time to warm up; make sure the previous day has also been at least 60:F prior to painting. Minimum floor temperature for painting is 55:F. Painting in mid-afternoon ensures the best cure.

Prepare the surface

Preparation Instructions

Remove any oil or grease spots on your floor. Use a scrub brush and a cleaner/degreaser (such as Simple Green.) or use a solvent such as mineral spirits. Scrub the spot thoroughly and wipe up excess cleaner with rags or paper towels to keep contaminants from spreading. Rinse thoroughly with fresh water. Repeat as necessary to completely clean.

Mix all concentrated cleaner with 2 gallons of water. For best results, use a plastic watering can to evenly distribute solution. Mix until dissolved. (The cleaning solution contains a mild citric acid.)

Pre-wet the floor using a hose. Remove pooled water with a squeegee or broom to avoid leaving puddles. Spread the cleaner mixture over a 10′ x 10′ section of the floor. Scrub vigorously with a stiff bristle brush to loosen dust and dirt. While working, keep the entire section wet until the entire section has been cleaned and rinsed.

Rinse each section thoroughly before starting the next section. For best results, use a foam squeegee to remove the rinse water from the surface and to move dirt and contaminants out of the garage. Repeat twice before continuing to the next section. Once all sections are completed, rinse and squeegee the entire garage floor to remove any cleaner that has been tracked on previously cleaned areas. A wet/dry vacuum can also be used to eliminate excess water, dirt and contaminants. Do not leave pooled water on the floor. The cleaner will not discolor driveways or harm grass or plants if rinsed thoroughly.

Allow the floor to dry completely. Wipe your fingers over the clean, dry floor. If you see any dust or powder on your fingers, repeat the rinsing and scrubbing until the floor is clean. If your fingers remain clean, continue to the next step.

Apply the coating


Do NOT mix Paint Chips with EPOXYShield. Pour the contents of A into B and stir thoroughly for at least 3 minutes. ALLOW MIXED PRODUCT TO STAND FOR AT LEAST 60 MINUTES BEFORE ROLLING THE COATING ONTO THE SURFACE. Do not leave container in direct sunlight. Mix again before applying. NOTE: Parts A and B must be mixed as stated.

This product must be used within 3 hours of initial mixing (pot life). This time decreases at higher temperatures. If temperature is above 85:F, begin rolling on the coating after 30 minutes.


After the full 60 minutes use a 1/2 nap roller cover and 9 roller frame to apply an even coat of EPOXYShield onto the surface. Apply in 4′ x 4′ sections so that paint chips can easily be scattered on the freshly-coated surface. Maintain a wet edge to prevent lap marks and gloss differences.Toss the decorative paint chips onto the wet film. (Note: This step may be skipped if chips are not desired. This will not affect the performance of the coating.) Immediately continue to coat the next section. (Note: Fresh paint can be applied over the loose chips that lay outside the previously painted area). Only one coat is necessary. This product must be used within 3 hours of initial mixing (pot life).

EPOXYShield Facts

Dry Time

Surface should be ready for light foot traffic in 12-16 hours, heavy items and normal foot traffic in 24-48 hours. FOR FULL CURE AND VEHICLE TRAFFIC, ALLOW 7 DAYS. Temperature and humidity may affect actual dry time.

EPOXYShield Clean-Up

Wash all tools and equipment immediately with warm water and mild detergent. Allow any unused product to harden in the container and discard according to local regulations.

EPOXYShield Coverage

Each EPOXY Shield kit contains enough surface treatment to cover approximately 250 square feet of smooth, bare concrete (a normal 1 car concrete garage floor). Very rough or porous concrete may require more material. Expect coverage of 125-200 square feet on those surfaces.

Safety Information

AVOID CONTACT WITH SKIN AND EYES For skin contact, wash affected area with soap and water and rinse well. FIRST AID: In case of contact with eyes, flush with cold water for 15 minutes. If swallowed, do not induce vomiting. Drink 1-2 glasses of water or milk. Contact a physician immediately.
