Mira 4400 Multicoat Waterproof Tanking Solution - 6kg
Additional Products (Optional)
Mira 4400 is a ready to use highly flexible synthetic latex coating developed for application to a broad range of construction substrates prior to tiling. The cured coating remains elastic and forms a seamless barrier to water. Main application areas are internal and external walls and floors where water protection is required including wetrooms, bathrooms, showers, terraces and balconies.
Highly elastic, viscous material for water insulation in wet rooms: bathrooms, terraces, balconies, washing room’s etc. Characteristics 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 Absorptive substrates should be primed with mira 4180 sealer, thinned with water in the ratio: 1 part of 4180 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 Consumption: Technical data
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 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.
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.
