Sikalastic®-715 Top Lo-VOC

Sikalastic®-715 Top Lo-VOC

SINGLE COMPONENT, ELASTOMERIC, LOW-VOC, WEAR AND TOP COAT

Sikalastic®-715 Top Lo-VOC is a single component, UV-resistant, aromatic, moisture cured, low VOC elastomeric polyurethane coating intended for use as the wear and top coat over polyurethane waterproofing membrane for pedestrian and vehicular traffic bearing applications, and as a protective top coat over polyurethane waterproofing membrane under a separate wearing course such as concrete, and tile in a setting bed. Optional Sikalastic® 700 ACL can be used to speed cure time.

Application

Consumption

Coverage


100 sf/gal. at 16 wet mils (14 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 and substrate temperatures, and other site-dependent factors. This will result in a lower coverage rate.
Application steps

MIXING

Thoroughly mix Sikalastic®-715 Top Lo-VOC using a low speed (400–600 rpm) drill with mechanical mixer (Jiffy) at slow speed until a homogenous mixture and uniform color is obtained (typically 1 minute). Add Sikalastic® 700 ACL (if required) into premixed coating and continue mixing until homogenous mixture and color is obtained (typically 3 minutes). Use care not to allow the entrapment of air into the mixture.

APPLICATION

Apply at the recommended coverage rate (see appropriate System Guide) 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 (see appropriate System Guide). 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 traffic or installing separate wear course.

  

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. It 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 recoating. Backroll aggregate where indicated.

   

Removal

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