depends on the water load; see figures herebelow under “Consumption”
The product can be stored for at least 12 months in its original unopened packaging if kept dry and frost-free. Frost destroys the liquid component. After thawing it is not allowed to use it.
Fields of application
weber.tec Superflex D 2 is used as flexible external waterproofing for masonry and concrete basement walls (external and internal
faces) below ground level, concrete floor slabs. For retrospective interior waterproofing on masonry and concrete basement walls below ground level (negative water pressure). For internal waterproofing of tanks with a water head up to 10 meters. As preliminary waterproofing and bonding layer under PMBC (polymer-modified bitumen coatings), such as weber.tec 915, 922, Superflex 10, Superflex 100 S and Superflex 2 K. Also as horizontal damp-proof course under ascending walls and as bonding layer on existing bitumen paints/coatings. Furthermore, as solid-bonded waterproofing under ceramic coverings (e.g. swimming pools/sanitary areas/wet-duty areas). For use indoors and outdoors.
- EMICODE EC 1PLUS: very low emission of volatile substances
- waiting time between each application on walls: 90 minutes
- open to pedestrian traffic and covering with tiles: after 4 hours
- weather-independent full drying within 24 hours
- dry residue > 95%
- crack-bridging > 1 mm
- suitable on any mineral substrate; a render coat on masonry is not required
- can be covered with render or paint
- resistant to frost and thawing salts
- resistant to UV rays
- after 3 days permanently resistant in underwater areas
- sprayable with peristaltic pump and screw pumps, like Wagner PC 1030 with air support
- Limits of use: do not use for the internal waterproofing of drinking water tanks or sewage water tanks. For drinking water tanks use the 1-comp. mineral normal-setting waterproofing slurry weber.tec 930. For sewage tanks request technical advice.
- Comply with the national standards and/or guidelines; if not issued, and if requested, refer to the norm EN 14891 “Liquid applied water impermeable products for use beneath ceramic tiling bonded with adhesives”, the norm DIN 18533 “Waterproofing of Ground-contacting Building Structures”, the norm DIN 18535. “Waterproofing of water tanks and pools”, the “Guideline for Planning and Execution of Waterproofing of Ground-contacting Building Structures with Flexible Waterproofing Slurries (MDS), issued by the German Construction Chemicals Association and the WTA leaflet 4-6”Retrospective Waterproofing of Ground-contacting Structures” (WTA = International Association for Science and Technology of Building Maintenance and Monuments Preservation). In case of doubt request technical advice.
- All characteristics mentioned in this data sheet are given for a temperature of 23 °C, without draft and a relative humidity rate of 50%.
- Higher temperatures and lower humidity rates accelerate, lower temperatures and higher humidity rates delay the setting time.
- In the case of pressure water, steel-reinforced concrete must satisfy the national standards (for ex. EN 206); if not issued and if necessary, request technical advice.
- In case of sunshine, carry out waterproofing works in shadow or in the morning or evening hours.
- Do not bond protective boards or insulation boards and do not fill the excavation pit until the material has not completely dried.
- Prior to backfilling the excavation pit use the drainage mat weber.sys 983 over the basement walls in order to protect the waterproofing system.
- After full drying of the last waterproofing layer weber.tec Superflex D 2 can be painted over with the silicone resin paint weber.ton 411 or the silicate egalizing paint weber.ton 414.
- If a render is planned on top of weber.tec Superflex D 2 on the external socket parts of the facade, apply the quick-setting stipple coat weber.san 951 S full-surface as bonding layer on the fully dry waterproofing layer.
- As alternative use the mineral bonding layer weber.dur 101 which is combed horizontally with a notched trowel (notch size ≥ 8 mm).
- In case of waterproofing under ceramic tiles or natural stones, all structural joints in the construction (movement, corner and connection joints) must be covered with the sealing tape system weber.tec 828 and incorporated in such a way, that they are congruent with the tile covering. When laying ceramic or stone materials, avoid damaging of the waterproofing layer.
- Do not add any foreign substances during mixing and application.
- Do not use the material on frozen substrates, at freezing or high temperatures (substrate temperature above 30 °C).
- If there is danger of reverse damp penetration through the basement wall take the appropriate measures (see here below under “Substrate preparation”).
- Slight color changes cannot be avoided in direct sunlight.
- Refer to the Weber application tip “General guidelines for basement waterproofing works with thick-layer bitumen coatings and reactive coatings” for full information related to important issues like assessment of water load, thickness control, and all execution details.
- The consumption figures given in this document will increase if the applicator lacks experience. In addition, the figure for the scratch layer of 0.5 - 1.5 kg/m² depending on the substrate roughness must be taken into account.
