Excel-Coat Epoxy Coatings Application Guide
Garage Floor Coatings (Vinyl Chip or Solid Color Finish)
1. All surfaces must be clean, sound and free of mastics or other contaminants that may interfere with bonding.
2. Curing of concrete shall be by means of water cure or dissipating compounds. Curing compounds shall be approved by an authorized representative of Excellent Coatings, Inc.
3. Concrete shall be cured a minimum of 28 days prior to installation of the Excel Coat Garage Floor Coating System.
4. On-grade slabs should have a moisture vapor barrier in place.
5. On-grade substrates shall be tested for moisture vapor prior to application of the garage floor coating. Test according to ASTM Standard Practice E 1907-97. Calcium Chloride test results shall not exceed more than 3.0 pounds/sq. ft. 24 hours.
6. Concrete finish shall be power metal float followed by a fine - medium hair broom finish or equivalent.
7. Concrete surfaces shall be free of excessive roughness, voids and protrusions.
8. Concrete shall be steel shot blasted or acid etched to assure a clean open surface. Surface profile should be between 5.0-10.0 mils. When acid etching neutralizes well, rinse thoroughly with clean water. Allow to dry thoroughly. (pH level shall be between 7.0-8.5.)
9. A degreaser may be necessary prior to shot-blasting if floor has an accumulation of grease and oil.
10. All tooled joints and control joints shall be routed, primed and caulked with a sealant approved by Excellent Coatings, Inc. Moving structural cracks should be primed and filled with an epoxy crack repair material.
11. Apply primer at a rate of 250 sq. ft per gallon. Allow primer to cure for 2-4 hours or until tack is gone. Cold or inclement weather will affect the cure time of al Excel-Coat products. Do not exceed 24 hours recoat window.
Note: Pot life of primer is brief. It may be best to mix half of the two-gallon kit at a time.
1. Mix the CM-15 for 4 minutes at a low to medium speed with a drill motor and mixing attachment.
2. Apply material at the rate of 250 square feet per gallon to yield 5.0 Mils dry. Pour material in a ribbon pattern and use red or white squeegee to pull the material tight over the substrate. Using a 3/8" nap phenolic core roller back roll the material, keeping the roll cover wet at all times.
3. Vinyl Color Chip Broadcast: Immediately following application of epoxy coat, chips may be broadcast into the wet material. Wear spiked (golf) shoes to gain access to the wet area during broadcast process. Broadcast chips by hand or by use of a sprinkling can. Chips may be broadcast for 100% coverage using 12 lbs. per 100 square ft. or for a lighter sprinkling, use 3-4 lbs. per 100 square ft. Monitor the application carefully for even coverage over the entire area. Allow to dry approximately 6-8 hours.
4. Aggregate Broadcast: For a solid color floor having a non-skid finish broadcast 36-60 mesh, bleached aluminum oxide. Wear spiked (golf) shoes to gain access to the wet area during broadcast process. Broadcast carefully by hand to achieve an even texture over the entire area. Ensure that aggregate is adequately embedded into at least 5.0 mils of wet material. Allow to dry approximately 6-8 hours.
5. Sweep the surface with a stiff bristle broom so that chips or aggregate are lightly scraped and those setting on an angle are removed. Using a wallboard scraper, scrape the surface carefully in one direction to remove loose and angled chips. Repeat the process in the other direction. Thoroughly sweep or blow floor clean of any remaining loose chips.
6. If using aluminum oxide, use a stiff bristle broom to sweep the entire surface to remove any loose aggregate.
1. For a clear finish, mix CT-332 according to manufacturer's directions and allow for 15-minute induction time before working with the material. Apply material in a ribbon pattern and squeegee material tight to surface and back roll, ensuring that the roller cover stays wet at all times. Apply material at the rate of 350 square feet per gallon. Allow seal coat to dry 12-24 hours before applying a 2nd clear coat. Do not exceed 24 hours between coats.
2. For a pigmented finish over aluminum oxide texture, apply CT-352 in the same manner as above. A second pigment coat using CT-352 is optional.
A final clear coat may be applied in the same manner as the previous seal coat. Allow material to dry 3-5 days before driving onto surface.
