Surface Preparation
The concrete surface must be clean, dry and free of loose material. New concrete should be allowed to cure for 28 days prior to coating. Remove oil, dirt, grease and other chemical contaminants by cleaning with detergent or other suitable cleaner. Rinse thoroughly. Use Cemtetch® Self Etching Cleaner to remove unsound laitance and create a proper surface profile to the concrete. Rinse thoroughly and allow to dry before application of the Clear Coat. NOTE: Concrete floors on grade must be free of moisture transmission from the ground. If there is any doubt about the dryness of the concrete, conduct a test by simply taping a piece of 4 mil plastic sheet 18" by 18" on the bare concrete for 24 hours. Be sure to tape all four sides. After 24 hours, check the concrete for signs of moisture. The concrete will be darker if damp. If moisture is found, allow additional drying time (10-14 days) and repeat test. Persistent moisture transmission will prevent proper performance of the coating, please contact a Watco Industrial Flooring Expert at (855) 627-6350 for assistance. Also, check for curing compound or other types of sealers by pouring a small amount of water onto the concrete. If water soaks in, the surface is suitable for coating. If water beads up on the concrete, the surface is not porous and a test application is warranted to ensure proper adhesion will develop. Sanding or mechanical abrading may be required if proper adhesion does not develop. Previously coated floors need to be in good sound condition with proper adhesion to the concrete substrate. Check the adhesion of the previous coating by cutting a small X in the coating using a sharp razor knife, firmly apply a piece of 2" duct tape over the center of the X cut, then pull off with a fast snap. The coating is suitable to topcoat if no significant previous coating is removed beyond the X cut. If the coating fails this test, then additional surface preparation is required. It is recommended previously coated floors be sanded and vacuumed prior to application of the Clear Coat.

Mixing
Combine the base and activator by power mixing. Mix at 500-750 rpm for 1-3 minutes. Do not over mix or use higher speeds. This can introduce air into the coating causing small bubbles in the finish. It is very important to transfer as much activator as possible, scrape the sides and bottom of the container thoroughly. Mix the two components together for 1-3 minutes being careful to not pull air into the mixture. NOTE: Do not scrape the sides or bottom of the mixed container. Use only the material that flows naturally out of the container. Doing so may result with un-activated material from the sidewall of the container being applied. This will cause soft spots in the coating.

Application
Be sure the floor is clean, dry, and dust free. If needed, vacuum to remove dust and debris. Apply only when air, material and floor temperatures are between 60-85°F (15.5- 29°C). Use a good quality phenolic core roller with a 3/8" lint-free nap. Do not excessively over roll and make all final passes in the same direction. For best results, maintain a wet edge and end application at natural breaks in the floor like control joints or expansion joints. Use in well ventilated areas.

Curing Time
Light foot traffic: 10 hours. Normal service: 24-48 hours. Vehicle traffic: 72-96 hours. Recoat: 10-24 hours, Do not exceed 48 hours.

Coverage
Bare concrete: Approximately 250 sq. ft. /gal. Coated surface: approximately 400 sq. ft. /gal.

Clean-Up
Clean up equipment with Xylene. See technical data sheet for additional product and application information.
