SELF LEVELLING COMPOUND
Formerly Self levelling compound
For perfectly even floors
Reliable self-leveling indoors
- Self-leveling: Highly flowable and easy to apply. For perfectly even substrates under floor coverings.
- 2-10mm application thicknesses, locally up to 15 mm, in one operation.
- Useable for wet areas like bathrooms.
- Suitable for floor heating.
- Walkable after 6-8hrs.
- Tileable after 4 days.
Area of application
- Indoor: floor
- For humid areas
Heating and cooling area
- Floor
Processing method
- For hand and machine processing
- For levelling interior floors before laying floor coverings (tiles, floating floors, PVC, carpets, etc.).
- For levelling concrete floors.
- For using heating cables and mats for electric underfloor heating, including levelling cement screed surfaces with built-in hot water heating.
- The compound is not recommended for high load floors and floors subject to traffic loads; it is not intended as a final utility layer.

Substrate requirement
The substrate must comply with the applicable standards, must be solid, free of loose particles, free of dust, paint, residues of demoulding agents and efflorescence. It must be sufficiently rough, dry and evenly absorbent. The surface shall not be frozen or water-repellent. The substrate shall 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 8040 contact bridge. For non-standard substrates, modify with a suitable method to achieve the desired properties. Smooth out large unevenness in the substrate with appropriate Cemix materials and allow to dry and cure. The substrate shall comply with applicable codes, standards, or material manufacturer's recommendations.
Preparation of the mixture
Prepare the material by pouring the dry mixture into a suitable machine with the prescribed amount of water. Use potable water or water complying with EN 1008 to mix the mixture. Mix to a homogeneous mixture without lumps.

Processing instructions
After evenly spreading on the substrate, the layer is leveled, spread to the desired thickness using a fine-toothed spatula or trowel. The laid mixture is then blown off with a hedgehog 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.
The screed can be used to water 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 screed must be at least three times the thickness of the heated cable. Local levelling of unevenness may be up to 15mm.

Treatment after application
After application, the direct negative effects of sun, heat, humidity and draughts should be avoided. Protect from frost and rain. Direct heating of the surface is prohibited.
The surface is walkable in about 6-8 hours after application, full load after laying floor coverings. Laying of floor coverings can be done after the screed has dried to the required value according to ČSN 74 4505. Under normal conditions the screed 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.
