SikaLevel® Primer

Concrete primer for use with SikaLevel Self Leveling Underlayment

4.4 (180)

SikaLevel® Primer is a one-part, water-dispersed and solvent-free, acrylic-based solution use to prime and seal floor surfaces prior to the application of SikaLevel Underlayment.

  • Ready to use, no dilution required.
  • Water-based and solvent-free.
  • Penetrates substrate to reduce outgassing and formation of bubbles in the underlayment.
  • Prevents water loss from the underlayment into the substrate.
  • Quick-drying and fast film formation to increase productivity.
  • Achieves excellent bond values throughout the recommended range of application temperatures.
  • Effectively seals concrete surfaces in a single, economic operation.

Application steps

MIXING

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

APPLICATION

Ensure that both concrete/cement based substrates and ambient temperatures are between 50 °F (10 °C) and 95 °F (35 °C) before commencing the application of SikaLevel® Primer. The stated application temperatures are to be achieved before priming and should be maintained for a period of at least 3 days after installation of the underlayment. Should colder conditions prevail, make allowance for the use of indirect and vented heaters to achieve and maintain the application temperature required. Where temperatures exceed 86 °F (30 °C), refer to and follow ACI hot weather application and protection guidelines.

  

Tooling & Finishing

Apply SikaLevel® Primer by brush or roller (long nap roller for rougher surfaces), working the material into the prepared substrate. Typically, one single application is required; however, porous substrates may require two or more coats of primer to effectively seal the surface. Ensure coverage is at most 325 to 500 ft2/US gal, 10 to 12 m2/L per coat, depending upon the substrate, but ponding of the primer on the surface must be avoided and puddles must be removed. Where multiple applications are necessary to seal the surface, allow previous coats to become tack-free before applying additional primer. When first applied, SikaLevel® Primer 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.

  

Over Painting

To ensure proper adhesion, SikaLevel Underlayment must be applied within 24 hours of the application of the SikaLevel® Primer, but only once the primer is clear (without milky spots) and dry to the touch (typically after a minimum of 2 hours drying time under normal environmental conditions). Lower temperatures and/or humid conditions may extend the drying time between priming coats or before installation of the underlayment.
