Mira Thermoplan Self Levelling Compound

Mira Thermoplan Self Levelling Compound is suitable for use with several subfloor materials such as concrete, old tiles or wooden subfloors

One bag provides the following coverage:-

1.5 SQM with a Levelling Compound depth of 10mm

2.1 SQM with a Levelling Compound depth of 7mm

3.0 SQM with a Levelling Compound depth of 5mm

5.0 SQM with a Levelling Compound depth of 3mm

Basically take the depth of levelling compound required, and Multiply by 1.7. Then divide by 25, and multipy the number of square metres you wish to cover.

Uses

Mira Thermoplan is suitable for preparing of even and smooth under-floor layers; it can be applied on concrete subfloors, old tiled floor, wooden-based subfloors, and painted surfaces. It can be used in houses / flats, offices, hospitals, schools, supermarkets, stores, etc. Also used for the covering of underfloor heating cables and mats, or the preparation of sloped floors. Its advantages are versatility and applicability for quick works.

Hardened surface can be covered with any type of facing or lining e.g. ceramic tiles, carpet or vinyl lining, wood, parquet, cork etc. Floor with light traffic can be painted, as the final treatment.

Subfloor preparation

The subfloor must be stable, dry, compact, cleaned of dust, grease, oil etc. Concrete slurry (if any) should be removed, weaker parts of substrate should be removed and then repaired again. Grease, oil, dirt should be removed with 7110 base cleaner. The entire surface should be clean of dust. A concrete subfloor should be primed with mira 4180 primer thinned with water. Thinning ratio: 1 part of 4180 primer and 1-3 parts of water, depending on absorptivity of the substrate. Non-absorptive substrate should be primed with non-diluted 4180 primer and then powdered with thermoplan, which must be rubbed into freshly spread 4180 primer. Wooden-based substrate should be primed with non-diluted 4180 primer. Drying time 1-2 hours. Do not leave any puddles. The primer improves adherence, prevents air bubbles and de-watering of mortar. If more than one layer is laid, each layer must be primed.

Technical conditions

Mixing:

Thermoplan should be mixed in proportion: approx. 4,5 l of water for 25 kg of dry Thermoplan. Mix for approx. 2 minutes with a slow-rotating mixer or in a pump mixer, then the mortar is ready to use. Mortar for slopes should be mixed in proportion 4 l of water for 25 kg of dry Thermoplan.

Application:

Prepared Thermoplan should be applied on the substrate, preliminary spread with a trowel and then the mortar levels by itself. Thermoplan could also be applied with a mixer-equipped pump. In such case maximum width of applied layer should not be greater than 6-8 m, large areas should be divided into smaller parts using for instance mira plan stop self adhesive foam band, during hardening of Thermoplan.

Temperature:

Minimum air and subfloor temperature +6°C. Optimum temperature +10° to +18°C.

Application time:

After mixing the mortar should be applied within 30 min. Less water than prescribed decreases application time and flow of Thermoplan.

Hardening time:

Light traffic allowable after approx. 2 hours. Next works e.g. tile fixing can be continued after 6-12 hours. Damp tight or humidity – sensitive coverings can be applied depending on the remaining humidity in the Thermoplan, in the substrate and the supplier of the covering’s specification.

Consumption:

1,7 kg/m2 for each 1 mm of thickness.

Cleaning of tools:

Tools should be cleaned with water immediately after use. Hardened remainings can be removed only mechanically.
