Polyurethane - 1 Component Pedestrian Traffic Coatings - Sikalastic®-736 AL Textured

Single component, aliphatic, moisture cured, low VOC, elastomeric polyurethane pre-textured top coat

Sikalastic®-736 AL Textured is a single component, aliphatic, moisture cured, low VOC, elastomeric polyurethane coating intended for use as the traffic system top coat over polyurethane waterproofing membrane for pedestrian and vehicular traffic bearing applications. Sikalastic®-736 AL Textured provides superior UV resistance,slip resistance, color stability and cleanability, as well as more decorative options. Optional Sikalastic® 700 ACL accelerator can be used to speed cure time .

Application

Consumption

Coverage

100 ft²/gal. at 12 wet mils (10 dry mils)

83 ft²/gal. at 14 wet mils (12 dry mils)

72 ft²/gal. at 16 wet mils (14 dry mils)

62 ft²/gal. at 18 wet mils (16 dry mils)

Coverage rates provided are intended to achieve required wet film thickness under optimal conditions. Additional material may be required depending on substrate surface roughness and porosity, material ,substrate and air temperatures, and other site-dependent factors. This will result in a lower coverage rate.

Application Steps

MIXING

Thoroughly mix coating using a mechanical mixer (Jiffy) at slow speed until a homogenous mixture and uniform color is obtained (typically 3 minutes). Use care not to allow the entrapment of air into the mixture.

Field Tintable Base - Add 6 Sikaflex® 2C pigment color packs to coating. Thoroughly mix coating using a mechanical mixer (Jiffy) at slow speed until a homogenous mixture and uniform color is obtained with no streaks (typically 3 minutes). Use care not to allow the entrapment of air into the mixture. The use of 6 color packs per tint base unit provides 5 % pigment by volume, and is the standard recommended tint level.

APPLICATION

Wear coat (optional): Apply at the recommended coverage rate 18 mils wet (62 sf/gal ) using a 1/8” notched squeegee or trowel, and backroll using nap roller 1/4” or 3/8” to uniformly backroll prior to applying topcoat. It should be backrolled in every direction to create even texture. Do not dip and roll this product from pail.

Top coat: Apply at the recommended coverage rate 18 mils wet (62 sf/gal ) using 1/8” notched squeegee or trowel, and backroll using nap roller 1/4” or 3/8” to uniformly backroll . The Top coat should be backrolled in multiple directions to create even texture . Do not dip and roll this product from pail. Allow coating to cure a minimum of 4 hours at 70 °F and 50 % RH; coating must be tack free before overcoating. Allow coating to cure for a minimum of 72 hours before opening to vehicular traffic

Accelerator: Sikalastic 700 ACL may be added to Sikalastic® 736 AL Textured in order to speed cure time particularly in cold weather conditions. Mix thoroughly prior to application. Add a maximum of 1 quart to 5 gallons (or 1:20 ratio) and only to material that will be applied within 2-3 hours.

Removal

Remove liquid coating immediately with dry cloth. Once cured, coating can only be removed by mechanical means.
