- Indoor: floor
Heating and cooling area
- Floor
Processing method
- For hand and machine processing
- For levelling the substrate before laying tiles and floor coverings (floating floors, parquet, carpets, PVC, coatings, etc.)
- For general civil construction (flats, offices, hotels, schools, etc.) and light industries

Processing details
Learn more about technical details for processing this product.
Substrate requirement
The substrate must comply with the applicable standards, must be solid, free of loose particles, free of dust, paint, residues of demoulding substances and efflorescence. It must be sufficiently rough, dry and evenly absorbent. The surface shall not be frozen or water-repellent. The substrate must be stable in volume.
Substrate preparation
Depending on substrate water absorption and climatic conditions, the following is needed: Use Cemix 5400 primer on absorbent substrates, roughen smooth substrates or use Cemix contact bridge 8040. For non-standard substrates, modify with a suitable method to achieve the desired properties. Smooth out large unevenness in the substrate with suitable Cemix materials and allow to dry and cure. The substrate shall conform to applicable regulations, standards, or material manufacturer's recommendations.
Preparation of the mixture
Prepare the material by pouring the dry mixture into the prescribed amount of water and mixing it. Use potable water or water complying with EN 1008 to mix the mixture. Mix using a slow speed propeller mixer. Mix to a homogeneous, lump-free mixture and leave to rest. Then mix again briefly. Use suitable machinery when processing by machine.

Processing instructions
After spreading evenly over the substrate, the layer is spread to the required thickness using a fine-toothed squeegee or trowel. The laid mixture is then blown off with a roller, which also helps to level it. In the case of machine processing, the mixing is carried out, for example, with an m-tec duo-mix with accessories recommended by the manufacturer for the application of self-levelling floor compounds. The hose outlet must be equipped by a filter to catch dirt. In case of a requirement for reduction of surface absorbency it is necessary to aply a coating Cemix on the self-levelling compound.
The levelling compound can be used for underfloor water heating and electric heating floor mats only under the conditions of strict compliance with the ramp-up cycles specified by the heating mat manufacturer. The covering layer of the squeegee must be at least three times the thickness of the heated cable.
In the case of multi-layered screed casting, the previous layer must be allowed to dry (to a maximum moisture content of 5 % by weight), the substrate surface must be sanded, vacuumed and primed with Cemix primers.

Treatment after application
After application, direct negative effects of sun, heat, humidity and draughts should be avoided for 24 hours. Protect from frost and rain. Direct heating of the surface is prohibited. The surface is walkable in approx. 6-8 hours after application, full load after laying floor coverings. Laying of floor coverings can be carried out after the trowel has dried to the required level according to EN 74 4505. Under normal conditions the trowel requires 1 day per 1-2 mm thickness to dry to equilibrium moisture content.
Tool and cleaning instructions
Wash off tools with water immediately after finishing work. Clean dried residues mechanically.
