Use

Used for forming of 100% waterproof, elastic, joint-less membrane for water insulation on floors, walls, in wall and wall/floor corners, connections of wall joints between panels or elements, pipe junctions in wet zone of wet rooms. 4400 multicoat is used as a humidity and water protection layer on concrete floor, plaster, light weight concrete, fully joint brick wall, cement or anhydrite based substrate screed, plaster board, wooden based panels and old ceramic facings. The water shall be 'pressure-free' i.e. 4400 multicoat must not be used in swimming pools etc. Is also applicable on heated substrates. Ceramic, clinker and stone tiles can be fixed directly on the multicoat layer.

Substrate preparation

The substrate must be 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. Remove dust with a vacuum cleaner. Grease, oil, dirt should be cleaned with 7110 base cleaner. The entire surface should be clean of dust. Absorptive substrates should be primed with mira 4120 sealer, thinned with water in the ratio: 1 part of 4120 sealer and 3 parts of water. Non-absorptive substrates e.g. painted or made of ceramic tiles shall not be primed.

When the surface is dry mira 4400 multicoat can be applied.

Technical conditions

a. Mixing

4400 multicoat is ready-to-use and must not be thinned. Stir slowly the mass in the can/bucket before use.

b. Application

Spread the mass with a brush, roll or a trowel. First protect corners, wall/wall and wall/floor, joints between panels or elements by covering them with two layers of 4400 multicoat filled with safe coat strip; water installation inlets and water outlets should be protected with special flanges of safe coat called seal manchet. On walls 2 layers of 4400 multicoat should be laid, without safe coat. The second layer should be spread when the first is dried-up after 1-2 hours. On floors 2 layers of 4400 multicoat should be applied, with safe coat as a carrying layer.

Floor insulation should be done during one working cycle.

The safe coat mat should be covered completely with the second layer of 4400 multicoat to reach the proper thickness of min. 1,5 mm.

c. Temperature/weather condition

Minimum air and substrate temperature +6 degrees Celcius

When applied outdoor (terraces, balconies), protect the mass from intensive
sunlight and rain.

d. Application time:

Non used 4400 multicoat in the packing can be stored in closed can/bucket.

e. Hardening time:

The membrane is totally dry after approx. 12 hrs in the temperature of 10-15 degrees Celcius.

Consumption:

Walls: min. 1 kg/m2

Floor: min. 1,5 kg/m2
