  • highly flexible
  • protects substrates against moisture
  • excellent bonding

Main parameters

  • consumption: 0.9 kg /m²/ 1 mm thickness
  • foot traffic: after approx. 12 hours
  • bonding: min. 1.0 MPa

Protects substrates against moisture formed indoors – plasters and screeds in wet rooms (bathrooms, baths, showers, kitchens, wash rooms), particularly in wet zones of these rooms - around shower cabins, wash basins, bathtubs, sinks, etc.
Recommended for protection of elements particularly exposed to damage when in contact with moisture - gypsum (plasterboards and plasters) and anhydrite products, cellular concrete, etc.
Forms light type damp proofing – proofs places with no pressurised water action (free flow).
Enables installation of flexible protection of corners and expansion joints – along with ATLAS SEALING TAPE and CORNERS or ATLAS HYDROBAND tapes and corners embedded, secures the edges of joints between walls and screeds as well as the expansion joints.
Proofs surfaces around walls and floors, around passages of water and sewage system pipes – together with FLOOR or WALL RINGS or ATLAS HYDROBAND wall rings embedded.

Types of waterproofed substrates – cement, lime-cement and gypsum plasters, cement or anhydrite screeds, concrete and ferroconcrete elements, masonry made of brick, hollow blocks, blocks, plasterboard, OSB boards, etc.

Highly flexible – can be used on substrates with floor or wall heating systems and other surfaces subject to deformations.
Excellent bonding to typical construction substrates – minimum 2.2 MPa for concrete.
Coat damp proofing – forms a several millimeter thick coat, which has to be protected against mechanical damage, e.g. resulting from foot traffic – must be covered with screeds, plasters or cladding.
Resistant to substrate cracking - the maximum score width, where no coat cracking occurs is 2.5 mm.
Should only be mixed before use – a one-component membrane.
It can be used up gradually within 12 months – even if the bucket is opened and the material partially used, the remaining mass can be used up within the rest of the shelf life, i.e. 12 months since the date of manufacturing.
Comfortable use regardless the substrate type – it is easily applied onto plasterboards, OSB boards, cement or gypsum plasters, metal or PVC elements.
Easily controlled coat thickness – regardless the application tool - when using a brush, a roller or a steel trowel.
Excellent substrate coating, even with a single coat.
Allows easy visual assessment of thickness and uniformity of the applied coat – owing to intense colour and texture after drying.

Substrate preparation
The substrate should be:
even and sound – i.e. strong, stable and free from dust, dirt, salt efflorescence and weakly adhering substrate elements, remains of old paints, oils and other substances which may impair the membrane bonding. Any substrate scratches and defects must be widened mechanically and filled with cement mortar, e.g. ATLAS TEN-10. Dusty substrates and those made of gypsum materials must be
grinded and dusted,
dry – the surface should be completely dry, which should be checked with the “sheet test” . This consists in covering an area of approx. 1m² with plastic sheet. If condensation occurs on the inside of the sheet within approx. 12 hours, the substrate is yet not ready for the application of ATLAS WODER W. Freshly applied surfaces, e.g. plasters or screeds can be proofed when they completely dry, but not earlier than 14 days since their application,
primed – highly absorbent substrates should be primed with ATLAS UNIGRUNT emulsion. In order to improve the membrane bonding to smooth or hardly absorbable substrates, the substrate should be coated with ATLAS GRUNTO-PLAST mass.
Mass preparation
ATLAS WODER W is manufactured as a ready-to-use, uniform paste. It must not be mixed with other materials, thinned or thickened. After opening the bucket, the mass should be mixed in order to unify the consistency (low speed hand mixer recommended).
Damp proofing
The membrane should be applied in minimum two coats. The first coat is applied with a brush, starting from points where additional ATLAS SEALING TAPES, CORNERS and RINGS or ATLAS HYDROBAND accessories are to be used. These accessories are embedded in the freshly applied WODER W mass. The second coat can be applied once the first coat is completely dry (after approx. 3 hours). Subsequent coats can be applied using a brush or a steel float.
Finishing works
The set coat (after approx. 24 hours) should be permanently covered with floor, plaster or facing. The proofed surfaces must be protected against water action within approx. 3 days.

• The tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mass can be removed with ATLAS SZOP 2000 agent.
• Harmful to aquatic life with long lasting effects. Keep out of reach of children. Read label before use. Avoid release to the environment. Dispose of contents /container to appropriately labeled containers designed for selective waste treatment, emptied by an authorized company. Follow the instructions of the Safety Data Sheet.
• Keep in tightly sealed original and labeled containers. Keep in dry and cool places, protect against overheating (> 30 °C) and freezing - the product freezes and irreversibly loses its performance in temperature below 0 °C. Protect against direct sunshine. Incompatible materials: avoid contact with aluminum, copper and alloys of these metals. Shelf life in conditions as specified is 12 months from the production date shown on the packaging.
