Product description

Protects substrates against pressurised water – can form internal and external coat waterproofing of walls and floors, fire water or water reservoirs, pool beaches, etc.
Protects substrates exposed to precipitation and ground water action – balconies, terraces, facades, cellar walls, foundations, stairs, plinths (e.g. before tiling or applying decorative ATLAS DEKO M type renders).

Main properties

  • flexible, vapour permeable
  • protects against pressurised water
  • for sealing tapes embedding
  • high bonding, sets with no contraction
  • for mineral substrates

Main parameters

  • coat thickness: 1 - 3 mm
  • consumption: 2 kg /1 m² for 1.5 mm thickness
  • resistant to water pressure of 5 bars
  • bonding: min. 1.2 MPa

USE

Protects substrates against pressurised water – can form internal and external coat waterproofing of walls and floors, fire water or water reservoirs, pool beaches, etc.
Protects substrates exposed to precipitation and ground water action – balconies, terraces, facades, cellar walls, foundations, stairs, plinths (e.g. before tiling or applying decorative ATLAS DEKO M type renders).
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. Particularly recommended for walk-through shower systems.
Forms watertight coat – light, medium, or heavy type waterproofing (depending on the thickness of the applied layer).
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.
Waterproofs surfaces around walls and floors, around passages of water and sewage system pipes – together with ATLAS FLOOR and WALL RINGS or ATLAS HYDROBAND wall rings embedded.
Recommended for old, damp buildings – vapour permeability in combination with watertightness makes the mortar ideal for waterproofing partitions in heritage buildings.

Types of waterproofed substrates – mineral, cement and cement-lime plasters, screeds, concrete, reinforced concrete, masonry elements, plasterboards.

PROPERTIES

Go top
Resistant to water pressure of 5 bars (50 m water column).
High adhesion – for typical concrete substrates, minimum 1.2 MPa.
Resistant to UV radiation, frost and ageing.
Adheres to substrate without priming.
Sets practically without contraction – the linear contraction is limited to minimum - no contraction scratches or cracks, typical for cement mortars, occur during setting.
Coat waterproofing – forms a several millimeter thick coat, which has to be protected against mechanical damage. Can be covered with plasters, renders, tiles, natural stone, etc.
Can be used directly under tiles – replaces bitumen membranes and traditional foils requiring execution of screed before fixing the tiles.

TECHNICAL REQUIREMENTS

Go top
The product has been given the ITB Technical Approval No. AT-15-5031/2013, Declaration of Conformity No. 038 of 28.06.2013. The product has been given the Radiation Hygiene Certificate.

WATERPROOFING

Go top
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 mortar 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.
stable in standard conditions:
- concrete - 1 day since formwork removal (tiling after 28 days)
- cement-based screeds - 3 days (tilling after 14 days)
- ATLAS POSTAR 80 screed - 1 day (tilling after 1 day)
primed – the substrate should be initially intensively wet and matt-wet during the mortar application.
Mass preparation
Pour the mortar from the bag into a container with the suitable amount of water (see Technical Data for ratio) and mix using a drill with a mixer until homogenous. So prepared mortar should be used up within approx. 2 hours.
Waterproofing
The mortar must be applied upon the waterproofed surface in minimum two coats. The first coat is applied with a brush, starting from points where additional ATLAS SEALING TAPES, CORNERS and RINGS are to be used. These accessories are embedded in the freshly applied WODER S mass. The tapes should overlap with min. 5 cm. It is recommended to apply the mass onto the substrate as well as on the tape back. The tapes must not be pleated after installation. The second coat can be applied with a brush, a roller or a steel float when the initial one is properly set.
Finishing works
The set coat (after approx. 24 hours) has to be protected against mechanical damage with plaster, render, floor or facing. The waterproofed surfaces must be protected against pressurised water within approx. 3 days.

IMPORTANT ADDITIONAL INFORMATION

Go top
• Low temperatures and increased humidity extend the setting time of the mortar. Avoid work in strong sunlight.
• Any passages under water pressure should be protected with twisted ring sealers.
• Not treated surfaces should be protected against soiling.
• Metals: zinc, copper, aluminum or flashings should be coated with polyurethane resin prior to the mortar application.
• When waterproofing water tanks, it is acceptable to execute coves made of ATLAS TEN-10 or ATLAS FILER in the wall corners.
• The tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mortar can be removed with the ATLAS SZOP agent.
• Contains cement. May cause respiratory irritation. Causes skin irritation. Causes serious eye damage. May cause an allergic skin reaction. Keep out of reach of children. Avoid breathing dust. Wear protective gloves/protective clothing/eye protection/face protection. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. If skin irritation or a rash occurs: Get medical advice/attention. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing. Follow the instructions of the Safety Data Sheet.
• The mortar must be transported and stored in tightly sealed bags, in dry conditions (most preferably on pallets). Protect against humidity. Shelf life in conditions as specified is 12 months from the production date shown on the packaging. Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%.
