Product description

ATLAS WODER DUO EXPRESS is designed for application of composite waterproofing coats underneath ceramic tiles on terraces, balconies, loggias and external stairs.

PROPERTIES

Go top
ATLAS WODER DUO EXPRESS is a two – component, polymer-cement waterproofing material with addition of special modifiers, resins and fibers. Consists of dry mix (component A) and water dispersion of polymers (emulsion - component B) which should be mixed in 3:1 weight ratio.
 
High adhesion to the cement substrate – min. 1.0 MPa.
 
Modern technology of two-component waterproofing application – the second coat applied with the “wet on wet” method and tiles fixing just after 3 hours since the second coat application.
 
High water vapour permeability.
 
High elasticity – the mortar bridges scratches up to 0.75 mm wide, owing to:
-          content of specific polymers,
-          use of proper aggregate grain size,
-          thorough selection of fillers,
-          reinforcement made of polypropylene microfibers.
 
Resistance to UV radiation – ceramic tiles can be applied up to 6 months since the waterproofing coat application.
 
Layer made of WODER DUO EXPRESS keeps high mechanical resistance and does not require additional reinforcement – owing to the use of reinforcing fibers and specially selected polymer resins the mortar offers improved resistance to mechanical damage and impacts. Coating is resistant to temporary light foot traffic loads.
 
Frost – resistance – coating watertightness does not deteriorate during frost.

WATERPROOFING

Go top
Substrate preparation
The substrate should be:
even and sound – i.e. strong, stable and free from dust, dirt, salt efflorescence and poorly bonded substrate elements, residues of old paints, oils, bitumen coatings and other substances which may impair the waterproofing bonding. Any stable substrate scratches wider than 1.0 mm and gaps must be mechanically widened and filled with cement mortar, e.g. ATLAS TEN-10 or ATLAS MONTER T-5. Dusty substrates must be grinded and dedusted. In case of non-plastered walls, the wall must be made with full joints.
seasoned - freshly applied surfaces, e.g. plasters or floors can be waterproofed after appropriate stabilization, however, not earlier than 3 days since their application. In case of freshly applied screeds, this time can be shorter:
-          substrate made of fast-drying cement screed ATLAS POSTAR 20 can be waterproofed after 6 hours,
-          substrate made of fast-setting cement screed ATLAS POSTAR 80 can be waterproofed after 3 hours.
Caution! Stabilized screed should be protected from precipitation, free of technological humidity or capillary rising damp – dried after precipitation, leakage etc. Directly before the mass application, the dry substrate should be slightly moistened up to the ‘matt-wet’ state, leave no puddles.
Mass preparation
Product is manufactured as a set consisting of two components: dry mix (component A) and emulsion (component B) delivered in separate containers. The material preparation consists in pouring the liquid component (B) into an appropriate container, uniform adding of dry mix (A) and simultaneous stirring until homogeneous in consistency and color (approx. 2 min.). This operation should be performed mechanically with the use of a low-speed mixer. The mass is ready to use after approx. 5 minutes and remixing. It should be used up within approx. 45 minutes. Caution: While using only part of the product, the mass should be prepared by keeping the components weight ratio (3 parts of dry mix A and 1 part of emulsion B).
Waterproofing coat application
Directly before the mass application, the dry substrate should be slightly moistened up to the ‘matt-wet’ state, leave no puddles.
Application should begin of protection of corners and areas around installations passing through walls and floors (with ATLAS SEALING TAPES, CORNERS AND RINGS or ATLAS HYDROBAND 3G accessories). The tape should be cut to size and placed on the layer of mass applied with a notched trowel of 6 mm notches or with a brush.
Excessive mass should be pressed out with the smooth trowel edge. The adjoining tapes should overlap by min. 5 cm. Apply the mass on the tape joints with a brush, press out the excessive mass.
Waterproofing coat should be applied in minimum two coats. The first one is a thin coat which should be applied with a steel trowel or a paintbrush, by rubbing the mass into the substrate. Caution: the first layer should coat 100% of the surface intended for waterproofing.
The second coat should be applied directly after the application of the first coat, as per the “wet on wet” method. It should be applied with a notched trowel of 6 mm notches. Then, the mass should be smoothened with the smooth trowel edge. Caution: when first coat gets dry and it’s not possible to apply the second coat with the “wet on wet” method, then it is acceptable to apply it when the first coat sets. In that case, the second coat should be applied 2 hours since the first coat application.

• Not treated surfaces should be protected against soiling.
• Low temperature and increased humidity extend the time of mortar setting. Avoid application in strong sunlight.
• The tools must be cleaned with clean water directly after use. Residues of difficult to remove set waterproofing can be cleaned with ATLAS SZOP and ATLAS SZOP 2000 agents.
• 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.
• Component A (dry) should be stored in tightly sealed and labelled packaging, in dry conditions (preferably on pallets).  Do not expose to the direct sunlight. Keep in dry, cool and well ventilated room, away from incompatible materials (see section 10 of Safety Data Sheet), beverages and food. Protect from humidity – product gets irreversibly solid under exposure to the humidity. While maintaining conditions above, no adverse reactions known. Component B should be stored in dry, cool and well ventilated room in properly labelled and tightly sealed original packaging. Avoid direct sunlight, heat sources, hot surfaces and open flame. Storage temperature from +5⁰C up to +30⁰C, protect from freezing. Product should be thoroughly stirred before use. While maintaining conditions above, no adverse reactions known. Shelf life (component A and component B) is 12 months from the production date shown on the packaging.
