Usage

  • Sikafloor®-30 Level (PK) is a floor self levelling screed to level or smooth screeds and concrete floors at a thickness between 4 to 30 millimeters in one working step.
  • Sikafloor®-30 Level (PK) is useable as screed for industrial service conditions when sealed with a PU or EP resin topcoat from medium to high load (heavy traffic and forklift pallet truck with impact load).
  • Under interior low load service conditions, the Sikafloor®-30 Level (PK) can be used without a topcoat.  
  • Sikafloor®-30 Level (PK) is also suitable for filling, smoothing and levelling of suitable substrates before applying parquet, ceramic tiles, seamless resin floors, textile, elastic floor coverings.
  • Sikafloor®-30 Level (PK) is useable as screed for exterior areas when sealed with an waterproofing layer.

PRIMING:

High loads intended use of the floor: Priming with epoxy resins such as Sikafloor®-161 fully broadcast with quartz sand aggregate from 0.3 to 0.7 millimeters.

Normal intended use of the floor (only interior areas): The one-part acrylic primer Sikafloor®-01 Primer is recommended for a pore free surface with very good surface adhesion. Please refer to the relevant Product Data Sheet for the recommended application details.

LEVELLING:

Apply to the required thickness from 4 to 30 millimeters.

The temperature will affect the pot life. 

Application at temperatures above +35 °C will reduce the pot life and the working time. Temperatures below +35 °C will increase the pot life and extend the working time.

Waiting Time / Overcoating

Suitable for overcoating with impermeable or moisture sensitive coatings after:

  • Layer thickness up to 15 millimeters: 24 hours*
  • Layer thickness up to 30 millimeters: 48 hours*

Suitable to be covered with ceramic covering after approximately 24 hours. It is recommended to overcoat Sikafloor®-30 Level (PK) within 7 days.

* Times are approximate.

When overcoating Sikafloor®-30 Level (PK) 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 Coating Product Data Sheet).

Application steps

MIXING

Add cold water according to the desired consistency into a clean mixing vessel before slowly adding the Sikafloor®-30 Level (PK) powder. Sikafloor®-30 Level (PK) should be mixed by using low speed electric mixer (approximate 300 to 400 rpm), recommended is the use of a double disc stirring paddle or spiral mix paddle for 3 minutes or until the mix is free of lumps.

After mixing leave the material to stand in the container for approximately 2 minutes until majority of air bubbles have dispersed.

In case of higher water temperature, the water could be cooled down by using clean ice.

Note: Do not mix Sikafloor®-30 Level (PK) with cement or other cementitious product. Do not add extra water or other ingredients. Mix only full bags for best results.

APPLICATION

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. Best application time would be during falling temperatures.
