Sikalastic®-720 One Shot Arctic Vehicular System
After mixing, immediately pour the mixed Sikalastic®-720 One Shot Arctic onto the primed substrate. Leaving the Sikalastic®-720 One Shot Arctic in the pail will shorten the working time and pot life and will result in loss of material. Material should be poured out in a ribbon fashion and not in one large puddle. This will help make sure to get the most effective squeegee application. Apply Sikalastic®-720 One Shot Arctic over the entire area including previously detailed cracks. Coating should be tack free after about 6 hours at 70 °F and 50 % RH. Allow coating to cure for a minimum of 36 hours before opening to vehicular traffic
Proper Squeegee: Use a 3/8" V-notched squeegee or trowel to achieve the proper wet film thickness of 48 WFT (45 DFT). The squeegee must be stiff enough not to bend when significant pressure is placed on it - this will result in improper thickness. It is highly recommended to check thickness with a wet film gauge as work progresses. Sika offers a recommended squeegee; contact your local Sika rep for more information. (Recommended Squeegee: Seymour Midwest's Speed Squeegee HD 3/8" W x 1/4" D (30-45 mil), Black Neoprene Blade, SKU: 47565)
Squeegee Application and Finish Rolling: Push squeegee behind ribbon of material with consistent pressure on squeegee, do not pull squeegee towards applicator. All material applied should pass through the squeegee notches. After squeegeeing material to proper thickness, backroll with a 3/8" nap phenolic resin core roller in two directions, one perpendicular to the other. Wet roller with excess material before backrolling; using a dry roller for backrolling will result in improper application thickness. Do not apply pressure with the roller; do not push the material with the roller. If backrolled more than once in each direction the final texture could be inconsistent.

Proper Squeegee: Use a 1/4" V-notched squeegee or trowel to achieve the proper wet film thickness of 38 WFT (35 DFT). The squeegee must be stiff enough not to bend when significant pressure is placed on it - this will result in improper thickness.
