Usage

Sikafloor® Level-30 is an floor self levelling screed to level or smooth screeds and concrete floors at a thickness between 4–30mm in one working step.
Sikafloor® Level-30 is useable as screed for industrial service conditions when sealed with a PU or EP resin top coat from medium to high load (heavy-traffic + forklift pallet truck with impact load). Sikafloor® Level-30 is also suitable for filling, smoothing and levelling of suitable substrates before applying parquet, ceramic tiles, seamless resinfloors, textile , elastic floor coverings. Sikafloor® Level-30 is useable as screed for exterior areas when sealed with a covering, e.g. a coating.

Suitable for restoration work (Principle 3, method 3.1 of EN 1504-9).
Suitable for structural strengthening (principle 4, method 4.4 of EN 1504-9).
Suitable for preserving or restoring passivity (Principle 7, method 7.1 and 7.2 of EN 1504-9).

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

Covering	Layer Thickness	Waiting time
Impermeable or moisture sensitive coatings	≤ 15 mm	24 hours¹
Impermeable or moisture sensitive coatings	≤ 30 mm	48 hours¹

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® Level-30 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

Manual Application

When mixing manually add the dry powder (25 kg) into a container with the clean water.
Mix thoroughly for a minimum of 3 minutes, by use of an electric stirrer, recommended is the use of a double disc stirring paddle or a spiral mix paddle (< 500 rpm).

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

Pumping

When using a mortar pump with appropriate equipment (Putzmeister MP 20/25, DuoMix 2000 or PFT G5 FE) set the machine in a way that a uniform mixture is achieved. The use of a remixer is recommended.

Control the water dosage to achieve the required flow, measuring the final average flow diameter on a flat, clean, dry flow table.

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.
