Sika Sikafloor Level 30

Sika Sikafloor Level-30 is a polymer modified, pumpable, self levelling fast drying cementitious screed for higher thickness interior or exterior floors, meeting the requirements of class R3 according to EN 1504-3.

Best Uses

Sika 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 resin floors, 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). Also, suitable for structural strengthening (principle 4,method 4.4 of EN 1504-9), and suitable for preserving or restoring passivity (Principle7, method 7.1 and 7.2 of EN 1504-9).

• Suitable for use with under floor heating systems

Application

SUBSTRATE QUALITY / PRE-TREATMENT
The concrete substrate must be sound and of sufficient compressive strength (> 25 N/mm2) with a minimum pull off strength of 1.5 N/mm2. The surface must be clean, dry and free of all contaminants e.g. dirt, oils, grease, coatings and surface treatments etc. If in doubt apply a test area first. Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed. Cement laitance, paints or other surface treatment agents must be completely removed.

Suitable methods for surface preparation are high pressure water jetting or abrasive blast cleaning. Other pretreatments such as scarifying , milling, etc. must necessarily another post with a Jet/blast method to eliminate the remaining structural faults, this to remove cement laitance and achieve an open and sound textured surface. Prerequisite for a good bond between the substrate and levelling screed is an appropriate roughness of the substrate. The mean surface roughness should be as large as possible, but at least 1mm. Repairs to the substrate, filling of blowholes/voids must be carried out using appropriate products from the SikaTop®, Sika® MonoTop®, Sikafloor®, SikaDur® and Sikagard® range of materials.

All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.

A suitable one part acrylic primer such as Sikafloor® - 01 Primer. High mechanical forces on the floor, a floor placed on soil or poor weak substrates must be primed with Sikafloor®-150 or Sikafloor® -151 fully broadcast with quartz sand 0.3 – 0.8 mm. Remarks; quartz sand not aplied in excess and grains must not be fully sealed with the resin.

MIXING
By Hand
For 25 kg Sikafloor® Level-30 is required 5 to 5.25 l water. 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.
