- applicable on vertical and horizontal surfaces
- for use directly under tile substrate
- forms rubber-like membrane after drying-up
- easy in preparation
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
multi-coat 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 multi-coat 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 multi-coat 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 multi-coat can be applied.
Technical conditions:
a. Mixing
4400 multi-coat 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 multi-coat 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 multi-coat 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 Mira 4400 multi-coat: May 03 layers of 4400 multi-coat 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 multi-coat to reach the proper thickness of min. 1,5 mm.
c. Temperature/weather condition
Minimum air and substrate temperature +6°C. When applied outdoor (terraces, balconies), protect the mass from intensive
sunlight and rain.
d. Application time:
Non used 4400 multi-coat 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°C.
