  • To ensure proper adhesion, Sika® Level products have to be applied within 24 hours of the application of the Sika® Level-01 Primer Plus, but only once the primer is clear (without milky spots) and tack-free.

  • Lower temperatures and/or humid conditions may extend the drying time between priming coats or before installation of the underlayment.

Application steps

MIXING

  • Before applying Sika® Level-01 Primer Plus, thoroughly shake the container in which the material is supplied in to agitate the contents and to ensure all solids are distributed throughout the dispersion and a uniform consistency is achieved.

  • Mix with potable water (approx. 70 °F, 21.1 °C) into a suitable sized and clean mixing container. Mix for 1 minute with a low-speed drill (300 rpm) and a paint mixing paddle.

APPLICATION

  • Apply with a stiff bristle, exploded tip push broom.
  • Sika® does not recommend the use of paint rollers or spray equipment.
  • When first applied, Sika® Level-01 Primer Plus appears white; once dry, it is clear. This facilitates quality control in terms of complete coverage and clearly confirms when the underlay can be installed
  • Where temperatures exceed 86 °F (30 °C), refer to and follow ACI hot weather application and protection guidelines.
