Polyurethane - 1 Component Pedestrian Traffic Coatings - Sikalastic®-736 AL Lo-VOC

Single component, aliphatic, high-performance low VOC traffic-bearing top coat

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

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 and substrate temperatures, and other site-dependent factors. This will result in a lower coverage rate.

Application Steps

Thoroughly mix coating using a mechanical mixer (Jiffy) at slow speed until a homogenous mixture and uniform color is obtained (typically 1 minute). 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.

Apply at the recommended coverage rate using a notched squeegee or trowel, and backroll using a phenolic resin core roller. Apply aggregate evenly distributed at the appropriate rate immediately into wet coating and backroll if required . Allow coating to cure a minimum of 16 hours at 70 °F and 50 % RH or until tack fee between coats. Allow coating to cure for a minimum of 72 hours before opening to vehicular or pedestrian traffic.

Aggregate: Use clean, rounded or semi-angular oven dried quartz sand with a size gradation of 16-30 mesh for vehicular traffic and 20-40 mesh for pedestrian traffic, and a minimum hardness of 6.5 per the Moh’s scale. Alternatively, decorative ceramic-coated colored quartz can also be used for pedestrian traffic applications. should be supplied in pre-packaged bags and free of metallic or other impurities. Seeding of aggregate means an even, light broadcast short of refusal. A full broadcast of aggregate means a heavy application to refusal. Any loose aggregate must be removed prior to re-coating. Backroll aggregate where indicated.

Decorative Flakes: Use clean and dry colored vinyl flakes with a minimum size gradation of 1/8” for pedestrian traffic applications. Seeding of flakes means an even, light broadcast short of refusal. A full broadcast of flakes means a heavy application to refusal. Any loose flakes must be removed prior to re-coating.

Accelerator: Sikalastic® 700 ACL may be added to Sikalastic®-736 AL Lo-VOC 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.
