720 Base Coat



Detailing Non-structural cracks up to 1/16” - Apply a detail coat of Sikalastic 720 Base at 24 wet mils, 4” wide, centered over the crack. Allow to become tack free before overcoating.

Cracks and joints over 1/16 up to inch - Rout and seal with Sikaflex 2c or 1a sealant and allow to cure. Apply a detail coat of Sikalastic 720 Base at 24 wet mils, 4” wide, centered over crack. Allow to become tack free before overcoating.

Joints over 1 inch - Should be treated as expansion joints and brought up through the Sikalastic Traffic System and sealed with Sikaflex 2c or 1a sealant.

Base Coat Premix mix Sikalastic 720 Base Part A and Part B material 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 sides 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. Apply at the recommended coverage rate (see System Guide) using a notched squeegee or trowel and backroll using a phenolic resin core roller. Extend base coat over entire area including previously detailed cracks and joints. Allow coating to cure a minimum of 3-4 hours at 70°F and 50% RH or until tack free before top coating.
