Fields of application
weber.san 952 is used as a highly porous and vapour-permeable masonry repair damp-proof render.
Particularly dedicated for use in case of high salt content. Due to its porous structure it is able to take up damaging salt crystals and hence it can lead to a good drying of the damp masonry.
Suitable on the internal side of damp and salt-contaminated of basement walls below ground level and on external side of masonries above ground level (splash water areas/facade socket areas), damaged by ground damp and salts.
To be overcoated with a damp-proof render like weber.san 953, 954 or 958.
For use indoors and outdoors.
Main features
- high salt-storage capacity, thanks to its high air content
- highly open to water vapour diffusion
- resistant to frost and weathering
- low capillary water absorption
- easy application
- for mechanical and manual application
General notes
- All characteristics mentioned in this data sheet are given for a temperature of +23 °C, without draft and a relative rate of humidity of 50%.
- The relative air humidity rate should be max. 60 % and the air and substrate temperature > +5 °C to ensure proper setting.
- Observe the general rendering application rules.
- The product is not allowed to come into contact with gypsum or gypsum-containing building materials.
- A complete drying out of the masonry can only be achieved by additional measures, like the installation of a horizontal damp-proof barrier with the silicone micro-emulsion-based injection liquid weber.tec 940 E or the silane-based injection cream weber.tec 946 and/or the installation of vertical waterproofing on the exterior side of basement walls, for ex. the 2-comp. lightweight bitumen waterproofing thick coating weber.tec Superflex 10, etc.
Special notes
- Do not add foreign products during mixing and application.
- For application comply with the national standards and/or guidelines relating to works with damp-proofing of masonries (for ex. WTA leaflets 2-9 “Masonry Repair Damp-Proof Systems” and 4-6 “Subsequent Damp-Proofing of Ground-contacting Structures”). If not issued and if necessary, request technical advice.
