Sikalastic®-710 NP Base

Sikalastic®-710 NP Base

Single component, elastomeric, crack-bridging, primerless, waterproofing base coat

Sikalastic®-710 NP Base is a single component, aromatic, moisture cured, elastomeric polyurethane coating intended for use as the waterproofing base coat under polyurethane or epoxy wearing surfaces for pedestrian and vehicular traffic bearing applications, and as the waterproofing base coat under a separate wearing course such as concrete, and tile in a setting bed. Sikalastic®-710 NP Base can be a direct replacement for Sikalastic® 710 in all applications.

  • Excellent crack-bridging properties and flexibility, even at low temperatures
  • Primer not required for typical applications
  • Resistant to water and deicing salts
  • Alkaline resistant

NOTE: Coverage rates provided are optimal and are not guaranteed. Coverage rates will vary depending on temperature, surface roughness and porosity, aggregate selection and embedment, and application technique.
Application steps

MIXING

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.

APPLICATION

Apply at the recommended coverage rate (see Sikalastic® 710/715/735 AL 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 16 hours at 70 °F and 50 % RH or until tack fee before top coating. Allow coating to cure for a minimum of 72 hours before installing separate concrete pavement or tile wear course.

  

Removal

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