Applications & Uses

- Application Area
- Application Method
- Product Uses
- Three-coat garage floor system consisting of self-priming color primer/sealer followed by clear “bed” coat for accepting and wetting decorative flake chips (or other decorative media), followed by clear sealer/finish coat.
- Final clear sealer/finish over decorative concrete surfaces such as acid, color or dye stained, semi-polished concrete, polymermodified cementitious overlayments, or seamless multi-build epoxy/ color quartz flooring.
- High foot traffic, along with certain types of vehicle and material handling equipment.
- UV-resistant sealer/finish coat over safety surfacing systems or outdoor running tracks.
- Surface Preparation
Before application the receiving surface must be deemed structurally and mechanically sound, clean, and dry. Proper surface preparation is required for decorative-concrete, thin-film “Class-A -type” flooring systems or sealer/finish coatings. This is best achieved with mechanical grinding machines using diamond heads achieving a final 50 to 120-grit profile. Recommended surface profile is SP-2, Reference ICRI Technical Guideline No. 03732.
All receiving surfaces to be coated must be free of previous coatings, sealers, curing compounds, water repellents, laitance, efflorescence, oils, fats, grease, waxes, residues from cleaning compounds, non-visible soluble salts, and any other impediments to adhesion. The resulting surface must be a neutral pH 7.
Always check for potential bond breakers. One method is simply wiping the surface of the prepared concrete with a dark cloth. If white powder is present it should be removed. Another method entails pouring a slight amount of water on the concrete in random areas. If the water is absorbed into the concrete and leave it wet, the substrate is porous and thus acceptable. If water beads up, this indicates a bond breaker is still present and further surface preparation steps are necessary, such as additional mechanical grinding.
The rising moisture vapor emission rate must not exceed 3 pounds per 1,000 sq ft. (3 lb/1,000 ft) over a 24-hour period as measured by the calcium chloride test method, ASTM F-1869. The relative humidity in the slab must not exceed 80 percent. Any repairs that are not associated with normal cleaning and surface preparation work (i.e., cracks, chips, pitted/severe spalls deemed nonstructurally sound or have levelness issues) must be properly addressed and remedied prior to application of the coatings due to the fact that coatings follow the contours of the existing substrate. All spalls and cracks should be repaired in accordance with ICRI standards.
- Application Instructions
MIXING - Mix part A and part B in equal parts (1:1) using a clean, dry working vessel. Stir gently, avoid over-mixing or creating a vortex that would introduce moisture. Do not mix below the dew point, which will shorten the pot life. No induction time is required prior to use. If micro-media agents are to be incorporated, they are to be added after thoroughly mixing A and B.
POTLIFE - An approximate 25 to 30 minutes workable pot life exists at a temperature range of 70°F to 80°F (and 50% relative humidity). At higher temperatures and humidity the pot life can be shorter.
APPLICATION INSTRUCTIONS - Roller application is recommended. The roller must have an industrial grade phenolic resin core with a synthetic nap or lambs-wool cover. 1/8” to 3/8” nap.
CLEANUP - Use Xylene or MEK. Do Not use Alcohols.

Storage & Handling
- Storage and Shelf Life
The product must be stored in tightly sealed containers in a climate-controlled, dry location at normal room temperature. Containers which have been opened for use must be resealed immediately in a new container, preferably filled to the top (the more airspace in the container the greater the potential for reaction with moist air, decreasing the shelf life of the product).
Shelf Life - 12 months unopened. Store at 40°F to 100°F in a covered area (out of the sun).
