Self leveling concrete is typically used to create a flat and smooth surface with a compressive strength similar to or higher than that of traditional concrete prior to installing interior floor coverings

Sika® Level-325

Cementitious, self-leveling underlayment for interior and exterior self leveling

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 1-1/2” (3 up to 38 mm).


  • Concrete
  • Cement substrates
  • Rapid drying cement screed systems
  • OSB/Plywood only suitable for flexible coverings
  • Ceramic tiles, terrazzo or natural stones


  • Self-leveling
  • Levels new and renovates old floors
  • For interior and exterior use
  • Manual or pumpable applications
  • Excellent underlay for all type of residential and commercial flooring
  • Compatible with subfloor heating systems
  • Easy installations
  • High strength
  • Low shrinkage
  • Can accept caster wheel loading if the thickness is greater than 1/8’’ (3.2 mm)
  • No MVER (Moisture Vapor Emission Rate) limits on well prepared concrete


Application Information

Mixing Ratio

4.75 qts (4.5 L)

Fresh mortar density

133 lb/ft(2.1 kg/l)

(ASTM C-138)


Layer Thickness

Neat1/8” (3 mm)1-1/2” (38 mm)
Extended1/4” (6 mm)3” (76 mm)

*2″ (50 mm) in localized area

Product Temperature

65–75 °F (18–24 °C)

Ambient Air Temperature

41–86 °F (5–30 °C)


Note: When using water based adhesives on the finished product the best results will be achieved at ambient and substrate temperatures between 59 and 77 °F (15–25 °C).

Relative Air Humidity

< 75 %


Note: The substrate and uncured product applied on the floor, must be at least 5 °F above dew point to reduce the risk of condensation, blooming or cement laitance forming on the surface.

Substrate Temperature

41–86 °F (5–30 °C)

Pot Life

Approx. 20 minutes


As the temperature will affect the pot life, application temperature:

  • Above 73 °F (23 °C) will reduce the pot life and the working time.

  • Below 73 °F (23 °C) will extend the pot life and the working time.

Waiting / Recoat Times

Walk-on time: 4 hours


Suitable for overcoating with:

Non moisture sensitive floor covering

4 hours

Moisture sensitive floor covering

24 hours up to 3/8″ (9.5 mm)*


*Mat test (ASTM D-4263) above 3/8″ (9.5 mm)

The actual times will be affected by changing substrate and ambient conditions, particularly the temperature and relative humidity, plus the thickness of the material applied. When overcoating Sika® Level-325 always ensure the moisture content has achieved the required value for the subsequent floor finish adhesive / product being used, as the necessary waiting time will vary (with the application thickness and ambient humidity). Also please refer to the floor finish / adhesive PDS.
