Sikafloor®-122 Level

MULTI-PURPOSE SELF LEVELLING COMPOUND

Sikafloor®-122 Level Self Levelling Compound is a 1-part, ready to use, protein free, cement based, self leveller for floor smoothing
and levelling uneven rigid internal floors prior to applying final wearing coverings such as carpets, sheet vinyl, lino, tiles, laminates and timber.

  • Self smoothing and highly fluid.
  • Easy to place by pump or manual application.
  • Ready for use.
  • Low shrinkage.
  • Maintains good workability and joint healing throughout its pot life.
  • Fast setting and drying.
  • 2-4 hours walk on time (+20°C).
  • Good surface appearance and hardness.
  • Excellent freeze-thaw salt resistance.
  • Protein and formaldehyde free.
  • Underfloor heating applications beneath heating cables/pipes or on top of heated screeds
  SUBSTRATE MOISTURE CONTENT
The substrate can be in a SSD (saturated substrate dry) condition, but there must be no rising moisture prior to the dampening operation according to ASTM D 4263 (Polyethylene-sheet test).
For further information please refer to the Product Data Sheet of the primer used. 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.

Technical Information

Compressive Strength

> 15 N/mm² (after 24 hours / +20°C) (EN 13892-2)
> 30 N/mm² (after 28 days / +20°C) (EN 13892-2)

Thermal Resistance

Suitable for use with underfloor heating systems (not for embedment).

Application

Application Information

Layer Thickness

Featheredge to 6mm.

Ambient Air Temperature

+8°C min. / +35°C max.

Relative Air Humidity

< 75% max.

Substrate Temperature

+8°C min. / +35°C max.

Pot Life

20 minutes in conditions of +23°C / 50% r.h
The temperature will affect the pot life. Application at temperatures above +23°C will reduce the pot life and the working time. Temperatures below +23°C will increase the pot life and extend the working time.

Waiting Time / Overcoating

Suitable for overcoating with impermeable or moisture-sensitive coatings after :
Product layer thickness up to 10mm ~ 24h waiting time.
Times are approximate and at +23°C and 50% r.h. and thus will be affected by changing substrate and ambient conditions, particularly the temperature and relative humidity. When overcoating Sikafloor®-122 Level always ensure the moisture content has achieved the required value for the coating product, as the waiting time will vary with the application thickness and ambient humidity (refer to the top coat product data sheet).

Applied Product Ready for Use

At +20°C and 50% relative humidity:
Foot traffic ~ 3 hours.

Cover ~8 hours.
Lightly serviceable ~ 24 hours.
Fully serviceable ~ 7 days.
Note: Times are approximate and will be affected by changing substrate
and ambient conditions, particularly the temperature and relative humidity.
Consumption

Consumption

25kg will cover approx. 5m² @ 3mm thickness. 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

Unfilled (up to 6mm thick):
Mix Sikafloor®-122 Level with clean water only. Slowly add 5 parts powder to 1 part water (25kg powder will require 5 litres / 5kg of water). Mix in a suitable clean container using a mechanical mixer with a spiral mixing paddle at slow speed until fully mixed and a smooth consistency achieved. Occasionally during hot weather the product may require remixing during the 15 - 20 minute pot life to reactivate the self-levelling  characteristics. Do NOT add extra water. Discard any unused material after 20 minutes from initial mixing.

Mixing Time
Mix thoroughly for a minimum of 3 minutes.

Mixing Tools
Use an electric stirrer (< 500 rpm).

APPLICATION

 

Manual:

 

Pour the mixed material onto the primed surface and 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.
