Polyurethane - 2 Component Pedestrian Traffic Coatings - Sikalastic®-745 Textured

Two-component, integrally textured, aliphatic, fast-curing, solvent-free, traffic bearing wear and top coat

Sikalastic®-745 Textured is a two-component, aliphatic, chemically cured, 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, and as a protective top coat over polyurethane waterproofing membrane under a separate wearing course such as concrete or asphalt pavement, and tile in a setting bed.

Application

Application Information

20-30 minutes

Consumption

80 sf/gal. at 14 wet mils (14 dry mils)
70 sf/gal. at 16 wet mils (16 dry mils)
62 sf/gal. at 18 wet mils (18 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

Thoroughly premix Part A using a mechanical mixer (Jiffy) at slow speed to obtain uniform color and mixture, making sure to scrape the solids and the aggregate from the bottom and sides of the pail. The aggregate should be evenly diffused in the resin. Pour part B into Part A slowly and while mixing scrape the side of the container, Mix the combined material thoroughly until a homogenous mixture and uniform color is obtained (typically 3 minutes). Use care not to allow the entrapment of air into the mixture.

Wear coat: Apply at the recommended coverage rate 16 mils wet (70 sf/gal) using a 1/8” or 3/16” notched squeegee or trowel, and backroll using nap roller 3/8” to uniformly backroll prior to applying topcoat. It should be backrolled two times, one perpendicular to the other.

Top coat: Apply at the recommended coverage rate 16 mils wet (70 sf/gal) using a “1/8” or 3/16” notched squeegee or trowel, and backroll using nap roller 3/8” to uniformly backroll. The Top coat should be backrolled two times, one perpendicular to the other. Allow coating to cure a minimum of 4 hours at 70 °F and 50 % R.H.; coating must be tack free before overcoating. Allow coating to cure for a minimum of 36 hours before opening to vehicular traffic

Removal

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