Sika Level-325 High Strength, cementitious, self leveling underlayment for interior and exterior
Categories: Ceramic; Concrete

Material Notes: Sika® Level-325 is a one-component, durable and versatile cementitious underlayment for interior and exterior concrete and cementitious substrates. It can be applied manually or by pump to produce a self-smoothing, rapid-setting and flat substrate prior to the application of a final floor finish. Typical application thickness is 1/8” up to 1.5” (3 up to 38 mm), or up to 3” (76 mm) with aggregate.

Where to Use:

  • Concrete
  • Cement substrates
  • Rapid drying cement screed systems
  • OSB/Plywood only suitable for flexible coverings
  • Old substrates such as ceramic tiles and terrazzo
  • Old, water-resistant adhesive residues
Advantages:
  • Self-leveling
  • For interior and exterior use
  • High strength
  • Low shrinkage
  • Manual or pumpable application
  • Zero VOC content and low odor
  • Levels new and old floors
  • Can accept caster wheel loading if the thickness is greater than 1/8’’
  • No MVER (Moisture Vapor Emission Rate) limits on well prepared concrete
