Sikafloor® Level-15

Cementitious self levelling, fast hardening, underlayment for use 0.5 - 15 mm

Sikafloor® Level-15 is a one part, polymer modified, pumpable self levelling fast hardening cementitous underlayment for the levelling and smoothing of interior floors prior to the application of the final floor finish.

  • Fast application because of the good flow and cohesion of the fresh product
  • Easy to place by pump or manual application
  • Capable of levelling surfaces from 0.5 to 15 mm
  • Reduced shrinkage. Good bond and compaction
  • Fast hardening and good drying
  • Good surface hardness

Usage

Sikafloor® Level-15 can be applied manually or by pump to level floors at a thickness between 0.5 - 15mm, prior to subsequent finishing with ceramic or stone tiles, linoleum, PVC sheet, wood flooring or carpets etc.
  • Levelling of both large and small surfaces
  • Typical uses are in commercial, residential and domestic properties etc.
  • Provides a suitable substrate for ceramic, stone or vitrified clay tiles, carpets and wood flooring
Sikafloor® Level-15 is compatible with the Sika adhesives used to lay these types of floor finishes.

System information

System Structure

Priming:
Prime substrate with Sika® Pour on Floor Primer. Can also be primed with Sikafloor®-159 or Sikafloor®-161, broadcast with 0.4 - 0.7mm quartz sand. Please refer to the relevant PDS for recommended applications and details.
Levelling:
Place to the required thickness 0.5 - 15mm. Sikafloor® Level-15 is particularly suitable for the subsequent application of floor coverings using products from the Sikabond® elastic bonding range or tiling mortars from the SikaCeram® range.

Application

Application Information

Fresh Mortar Density

1.95 kg/l ± 0.03

Layer Thickness

Minimum: 0.5 mm. Maximum: 15 mm.

Ambient Air Temperature

+8°C min. / +30°C max.

Relative Air Humidity

~ 75% max.

Substrate Temperature

+8°C min. / +30°C max.

Dew Point: Beware of condensation! The substrate and uncured floor must be at least 3°C above dew point to reduce the risk of condensation, blooming or cement laitance on the floor finish.

Pot Life

Approx. 25 minutes (+20°C / 50% R.H.)

The temperature will affect the pot life. Application at temperatures above +20°C will reduce the pot life and the working time. Temperatures below +20°C will increase the pot life and extend the working time.

Waiting Time / Overcoating

Suitable for overcoating after 24 hours in 5mm thickness where 3% (Tramex) substrate moisture content is required. Times are approximate at +23°C and 50% r.h. and will be affected by changing substrate and ambient conditions, particularly the temperature and relative humidity. When overcoating Sikafloor® Level-15 always ensure the moisture content has achieved the required value for the coating product, as the waiting time will vary with application thickness, temperature and ambient humidity. (Refer to the top coat product data sheet.)

Applied Product Ready for Use

Foot traffic

~ 3 hours

Lightly serviceable

~ 24 hours

Fully servicable

~ 7 days

Note: Times are approximate and will be affected by changing substrate and ambient conditions, particularly the temperature and relative humidity.

 
Consumption

Consumption

~ 1.55 ± 0.1 kg of dry powder/m²/mm
This figure is theoretical and does not include for any additional material required due to surface porosity, surface profile, variations in level or wastage, etc.
Application steps

MIXING

Mixing: When mixing manually, place 4.6 – 4.8 litres of cool, clean water into a suitable sized clean vessel. Add a full bag (20 kg) of Sikafloor® Level-15 powder slowly to the water, mixing continuously. Mix thoroughly for a minimum of 3 minutes using a low speed electric stirrer (~ 300 - 400 rpm).

APPLICATION

Pump: Use a conventional floor screed dual stage mixer and pump, and control the water dosage to achieve the required flow, measuring the final average flow diameter on a flat, clean, dry flow table.

After placing onto the surface, apply by trowel or pin screed rake to the required thickness. Roll thoroughly with a spiked roller in two directions to remove any entrapped air.
Manual:
Pour the mixed material onto the primed surface and apply by trowel or pin screed rake to the required thickness. Roll thoroughly with a spiked roller in two directions to remove any entrapped air.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
