Excel-Coat Epoxy Coatings Application Guide
100% Solids Epoxy Color Quartz Flooring
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 International
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 International Moving structural cracks should be primed and filled with epoxy crack repair material.
11. Using a grinder smooth out excess crack filler. Vacuum away any dust or particulate.
12. 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 PC-1803 pre-measured components for 3-4 minutes at a low to medium speed with a drill motor and mixing attachment.
2. Apply material at the rate of 100 square feet per gallon to yield 5.0 Mils dry. Pour material in a ribbon pattern and use a roller or squeegee (red or white only) to pull the material over the substrate. Back-roll material using a spiked or porcupine roller to remove any air bubbles formed during the mixing process.
3. Colored Quartz Broadcast: Immediately following application of epoxy coat, colored quartz may be broadcast into the wet material. Wear spiked (golf) shoes to gain access to the wet area during broadcast process. Broadcast quartz by hand or by use of a sprinkling can. Be sure to seed quartz from above rather than broadcasting at an angle. Colored quartz shall be broadcast to refusal. Monitor the application carefully for even coverage over the entire area. Allow to dry overnight.
4. Lightly scrape surface to remove projections, protrusion, ridges and rough spots. Sweep in both directions to removed loose quarts. Vacuum to remove all loose quarts.
5. Second Color Quartz Broadcast: Following same procedure for first broadcast application, repeat this process. Once seeded, allow to dry overnight.
6. Repeat step #4 again before applying seal coat(s).
1. Mix the PC-1803 pre-measured components for 4 minutes at a low to medium speed with a drill motor and mixing attachment. Add 20-25 lbs. Color Quartz to one gallon of mixed resin. Blend materials together. Pour blended material onto primed floor surface and pull down with a ¼ inch notched trowel or squeegee. This should go down at approximately 45-65 mils dry for a 1/8 inch floor coating. Coverage will be approximately 20-24 square ft. per gallon of mixed product.
2. Once an area is trowelled, a second man on golf shoes (or spiked shoes) shall broadcast the dry color quartz onto the surface at rate of 1 lb. per square ft. Broadcast quartz to refusal and allow to set overnight. (This broadcast will bring the thickness of the system up to a nominal 1/8 inch thickness.
3. Lightly scrape surface to remove projections, protrusion, ridges and rough spots. Sweep in both directions to removed loose quarts. Vacuum to remove all loose quarts.
1. Seal Coat (s): Use a straight-blade squeegee to pull a coat of PC -1803 Clear or CT-332 over the floor at a spread rate of 160 square ft. per gallon.
Note: Excel-Coat CT-332 may be used for increased UV protection and durability. Remember to mix and allow for 15-minute induction time for this clear product.
2. For a smoother finish a second application of clear sealer may be applied. Apply this second clear seal coat after first coat has cured, about 8-14 hours. Do not exceed 24 hours between coats.
