84-26492	LIGHT GRAY INDUSTRIAL EPOXY FLOOR COATING

_

DESCRIPTION OF PRODUCT #84-26492 Epoxy Floor Coating is a high performance, two component, epoxy phenalkamine, self leveling floor coating. When applied over a properly prepared and primed concrete floor and clear coated (see Figure 1) it will provide state of the art protection from abrasion, acids, alkalies, oils, fuels, salt, moisture, and solvents. Designed to be visually attractive as well as functional, this pigmented coating can be used with or without a topcoat. With optional color coordinated vinyl chips added under a clear topcoat, a beautiful granite-like appearance is achieved. It can be used over new floors to enhance their beauty and serviceability, or over older floors to restore structural integrity and functionality at a fraction of the cost of concrete slab replacement. This product is not intended for consumer use and should be applied by experienced professional applicators only. PACKAGING This coating is packaged and labeled as 84-26492-A Epoxy Component and 84-B Hardener Component. Each component is supplied in 5-gallon pails filled to 2½ gallons each. The shipping containers may be used for mixing on the job site. RECOMMENDED USE See Table 1 for recommended

coating service specifications and required dry film thickness: TABLE 1 20-40 mils: Pedestrian and light vehicle traffic (drum dollies, carts, etc.); incidental chemical exposure such as cleaning compounds, household chemicals, etc. 40-60 mils: Light to moderate traffic and abrasion service (golf carts and light forklift trucks); moderate chemical exposure seen in food service areas, laundries, light duty warehouses. 60-80 mils: Heavy vehicle traffic or severe abrasion service (heavy duty warehouses, shop floors, vehicle garages); extreme or prolonged chemical exposure such as containment areas, manufacturing plants, and aircraft hangers. SURFACE PREPARATION Apply over clean, dry, properly prepared and primered substrates. Refer to #80-1 Epoxy Floor Primer for specific details on floor preparation and repair. MIXING INSTRUCTIONS Allow the components to reach room temperature before using, best results are obtained when applied at 70-80 °F. Completely pour a pail of B Component into a pail of A component and mix well with a low speed paddle mixer. Avoid entraining air into the coating. Then pour the mixed coating into the B Component pail just emptied and mix again (boxing).

Use only freshly opened shipping containers for mixing; mixing epoxy in previously used containers will accelerate the cure of the system dramatically. Always clean the mixer blades between each use. APPLICATION METHOD Using a notched squeegee sized for the desired dry film thickness (see Table 2), work with approximately 2 or 3 gallons of the coating on the floor at a time. Apply using a cross-coat pattern to assure complete wetting of the primed surface. Areas adjacent to obstructions may be coated with a brush or short napped roller (¼ inch or less). If the applied coating contains entrapped air bubbles due to mixing, they may be released by working it with a spiked roller called a 'porcupine roller'. Spiked shoes are useful for walking on coated surface areas with minimal disturbance. TABLE 2 Squeegee Notch Size Coating Dry Film ________________________________ 3/32 inch 20 mils 7/32 inch 40 mils 7/16 inch 60 mils If vinyl chips are being used, they must be applied while the coating is still wet, preferably immediately after application of a 5-gal mixed lot. The chips should be spread to the desired density over the surface by hand, where they will partially sink into the coating. Visually

appealing results have been obtained by spreading a mixture of 10 parts black to 7 parts white chips at a rate of 4-5 pounds per 1000 ft^2. After curing, scrape the floor and sweep or vacuum away vinyl chips that have not firmly adhered to the surface. When coating a large area over multiple days, leave a 6 inch wet edge (omit the vinyl chips at the borders) to tie in the next pass of coating. If touchup is needed, light hand sanding with fine paper will aid intercoat adhesion at the touchup areas. Sanded areas will not be visible after the clearcoat is applied. Apply #85-13586 Clear Epoxy Topcoat within 48 hours following applicable directions. THINNING AND CLEANUP Thinning of this coating should not be necessary under normal conditions. In very cold conditions (<50 °F) thin with xylol to a maximum of 2% or 12 ounces per mixed 5-gallon pail. Clean equipment with xylol or a xylol/MEK mixture

CURE AND RECOAT TIME This coating cures tack free in 8 to 12 hours when substrate temper-atures are at 70 °F. Recoat within 48 hours or reduced intercoat adhesion may occur. Longer curing times will be necessary when air or substrate temperatures fall below 50 °F. Ultimate cure and chemical resistance is achieved in 7-10 days.
