Sikalastic®-745 AL

12 months in original, unopened containers

Store dry at 4–35 °C (40–95 °F)

Condition material to 18–30 °C (65–85 °F) before using.

Resistant to de-icing salts.

20–30 minutes

Minumum 2 -4 hours, dependant on temperature and relative humidity. Contact Sika Canada if recoating after 24 hours.

Allow 36 hour minimum before open to vehicular traffic. Time can vary, dependant on temperatue and relative humidity.

2.0 - 2.5 m²/L (80 - 100 ft²/US gal.) at 16 - 20 mil w.f.t. per coat. 

Note: Actual coverage rates and material consumption will depend upon porosity and profile of the substrate. Test areas are recommended to establish correct coverage rates.

Premix Part A and Part B components using a mechanical mixer (Jiffy) at slow speed to obtain uniform color, making sure to scrape the solids from the bottom and sides of the pail. 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.

Prior to application, measure and confirm substrate moisture content, ambient relative humidity, ambient and surface temperature and dew point. During installation, confirm and record above values at least once every three (3) hours, or more frequently whenever conditions change (e.g. ambient temperature rise/fall, relative humidity increase/decrease, etc.). Sikalastic®-745 AL wear course may be applied in different build configurations to reflect the traffic patterns in specific zones of the parking garage.

Light Duty/Parking Stalls Option (partial broadcast):

Apply Sikalastic®-745 AL onto cured Sikalastic®-390 Membrane (within recoat window) at a rate of 2.0 - 2.2 m²/L (18 - 20 mil w.f.t. ) using a notched squeegee. Allow the material to self-level for 5 to 10 minutes then broadcast clean, round or semi?angular, oven-dried, #24 mesh quartz sand at 0.6 - 1.0 kg/m² (12 - 20 lb/100 ft²). Backroll to encapsulate aggregate and to ensure uniform finish. Allow sufficient cure time for the park deck coating before opening up to traffic.

Medium Duty/Drive Aisles Option (partial broadcast):

Apply Sikalastic®-745 AL intermediate coat onto cured Sikalastic®-390 Membrane (within recoat window) at a rate of 2.0 - 2.2 m²/L (18 - 20 mil w.f.t.) using a notched squeegee. Allow the material to self-level for 5 to 10 minutes then broadcast clean, round or semi-angular, oven-dried, #24 mesh quartz sand at 0.75 - 1.0 kg/m² (15 - 20 lb/100 ft²). Backroll to encapsulate aggregate and to ensure uniform finish and allow to cure. Apply Sikalastic®-745 AL onto cured intermediate coat (within recoat window) at a rate of 2.0 - 2.6 m²/L (15 - 20 mil w.f.t.) using a notched squeegee. Allow the material to self-level for 5 to 10 minutes then broadcast clean, round or semi-angular, oven-dried, #24 mesh quartz sand at 0.7 - 1.0 kg/m² (14 - 20 lb/100 ft²). Backroll to encapsulate aggregate and to ensure uniform finish and allow sufficient cure time for the park deck coating before opening it up to traffic.

Heavy Duty/Turn Lanes, Ramps, Entries, Exits and Ticket Booths Option (broadcast to full saturation):

Apply Sikalastic®-745 AL intermediate coat onto cured Sikalastic®-390 Membrane (within recoat window) at a rate of 2.0 m²/L (20 mil w.f.t.) using a notched squeegee. Allow the material to self-level for 5 to 10 minutes then broadcast clean, round or semi-angular, oven-dried, #24 mesh quartz sand at 1.75 - 2.5 kg/m² (35 - 50 lb/100 ft²). Once fully saturated, the coating will not accept any additional sand and the surface will be covered. Allow to the coating to cure before removing excess sand. Remove excess sand from the cured intermediate layer and apply Sikalastic®-745 AL at a rate of 2.0 - 2.5 m²/L (leaving approximately 16 - 20 mil w.f.t.) using a flat squeegee and backroll to level. Broadcast clean, round or semi-angular, oven?dried, #24 mesh quartz sand at rate of 0.15 - 0.3 kg/m² (3 - 6 lb/100 ft²) and lightly backroll to encapsulate aggregate and to ensure uniform finish. Allow sufficient cure time for the park deck coating before opening up to traffic.

NOTE: All coverage rates are approximate and may vary depending on substrate texture, particle shape and size and the quantity of the aggregate being used. Intermediate layers broadcast to full saturation will increase the following coating consumption significantly. User is advised that a 3 x 3 m (10 x 10 ft) mock up using actual materials to be used during project installation should be done to validate coverages, textures, slip resistance and suitability for expected traffic volumes.

Clean all tools and equipment immediately with Sika® Urethane Cleaner and Thinner. Once cured, product can only be removed mechanically.
