Application Instructions

Surface Preparation:

Because surface preparation is important to successful adhesion, be sure the application surface is sound, clean, level, and dry before you begin application. No grease, dust, curing compounds, laitance, bond inhibiting impregnations, waxes, or any other contaminants should be present. Dress off all rough spots and projections to level the surface. Make sure the concrete has an open textured surface by shot blasting or utilizing similar mechanical means, leaving a uniformly textured concrete surface. Sweep and vacuum with a wet/dry vacuum to remove any dirt or dust that remains in order to ensure a strong bond. Be careful not to over blast when shot blasting; There is a possibility that the shot blast pattern may be seen through the last coat, which is called “tracking.” The substrate should have a compressive strength of at least 3500 psi (24 MPa) at 28 days and, at the time of application, a minimum of 250 psi (1.7 MPa) in tension.

Priming:

We recommend that you use #1107 Epoxy Primer and follow application instructions on its product label.

Mixing:

If using with an epoxy color additive for pigmentation, follow mixing directions on the additive’s product label, being sure to add the color additive to the container of clear resin (Part “R”). The 3 Gallon Kit version of ChemKote 700 is packaged in 2.6 gallon proportioned kits for easy mixing and application at the job site. Each of these 3 Gallon Kits come pre-measured and consists of 1 five gallon pail of resin (Part “R”) and 1 one gallon container of hardener (Part “H”). If using the 3 Gallon Kit, pour the hardener (Part “H”) into the oversized can of resin (Part “R”). If using the 15 Gallon Kit, follow mixing instructions on the product label to ensure correct ratios and mix in a clean mixing container. Mix with a very low speed jiffy mixer for 2-3 minutes or until fully blended. While in the mixing stage, scrape down the sides and bottom with a flat or straight edge trowel at least once so that mixing will be thorough. Be sure not to introduce air bubbles while mixing. This coating has a limited pot life; Mix only what will be used within its pot life.

Application:

After the product is mixed, apply by pouring a ribbon-like bead onto the application surface and spreading evenly with a flat squeegee, notched squeegee, or trowel (at about 133 sq ft, or 12.35 sq m, per gallon). Do not apply less than 10 mils (which would be greater than 160 sq ft, or 14.86 sq m, per gallon). Work from left to right and then back. Back roll with a 3/8 inch nap roller and after 5-10 minutes roll with a plastic loop roller to remove all remaining bubbles. Protect the freshly coated floor from water, dampness, and condensation for at least one full day.

Critical Recoat Time:

Apply subsequent coats of this product or other products within 12 to 24 hours (if curing conditions are normal). If more than 24 hours elapses, the surface will need to be screened to the point of uniform dullness (no visible gloss) before adding further coats.

Limitations:

Do not apply ChemKote 700 if the surface temperature is not between 60°F (15.5°C) and 85°F (30°C). Do not apply if the substrate temperature is not at least 5°F (3°C) above the measured dew point. Do not use a thinner. Do not immerse or use where moisture can get in below the resurfacer. This product will discolor over time when exposed to UV light and certain types of artificial lighting; Apply a light stable, UV resistant topcoat if ultimate clarity/color retention is necessary. ChemKote 700 is not intended for exterior use.
