Surface Preparation
New Concrete: Laitance must be removed by diamond for a minimum of 28 days. The concrete must be structurally sounds, dry, and free of grease, oils, dust, curing compounds and other coatings or contaminants. Surface laitance must be removed. Rising moisture vapor emission rate must not exceed 3 lb. per 1000sq. ft. over a 24 hour period as measured by calcium chloride test method ASTMF-1869. The preferred method of surface preparation is to mechanically abrade the floor by diamond grinding to achieve a final 80-120 grit finish, reference profile CSP-2 according to ICRI. If patching is required, use a fast cure concrete repair.
Previously Coated: Previously coated surfaces must be sound and in good condition. Smooth, hard, or glossy finishes should be scarified by sanding or sweep blasting to create a surface profile. The Performance Epoxy is compatible with most coatings, but a test patch is suggested.
Note: Concrete must be visibly dry at time of application.

Mixing Equipment
Low speed drill and spiral mixing wand. Must pre-mix prior to use. Important: Hand mixing will produce inconsistent results and is not an approved method.

Mixing
Note: Before starting, ensure that the material, concrete surface, and the ambient air are all at 50-90°F. Mixing ratio is 2 parts by volume of Pat A to 1 part by volume of Part B.
Pre-mix both A and B sides prior to combining. Add Part A to the mixing container. Add Part B to the mixing container. Mix for 3 minutes.
For use as a sealer, we recommend thinning with xylene at a maximum of 16oz. per gallon.

Application Equipment
24" notched squeegee
18" short nap lint free mohair roller

Application
Mix only what you can squeegee and back roll within 30-45 minutes (approximately 1 gallon of mixed material per crew of two applicators wearing spiked shoes). Do not aerate the mix.
Before starting, ensure that the material, concrete surface, and ambient air are all at 50-90°F. Do not apply in direct sunlight or when temperature is rising. Wearing spiked shoes, immediately pour mixed Performance Epoxy on the floor in ribbons. Spread using a squeegee and then back roll using a short nap lint-free mohair roller.

Limitations
Do not apply if water or ice is present. Lower temperatures will slow cure time. Do not Store Performance Epoxy at temperatures below 50°F or above 95°F. Do not apply to slabs on grade unless a heavy uninterrupted vapor barrier has been installed under the slab. Solid color floors applied direct to concrete will require a primer. Do not apply Performance Epoxy is the floor is subject to moisture vapor drive or hydrostatic pressure. Performance Epoxy will yellow upon prolonged exposure to sunlight or high intensity artificial lights.
