Fields of application

weber.san 164 is used as watertight render on external earth-contacting basement walls and under damp-proof renders.
Also, as basecoat (underlayment) for flexible and 2-comp. reactive waterproofing slurries on internal side of basement walls in the cases of ground damp, non-pressure water and pressure water.
Also, as basecoat (underlayment) on external (earth-contacting) basement walls for bitumen waterproofing thick coatings (PMBC =polymer-modified thick bitumen coatings) or with flexible polymermodified thick-layer waterproofing coatings (FDP) as well as with rigid and flexible cement-based waterproofing slurries.
Furthermore, as waterproof and/or leveling render under flexible epoxy resin or flexible cementbased waterproofing products in swimming pools, service water tanks, etc.
In addition, as render and/or leveling mortar on socket parts of facade.
For use indoors and outdoors.

Main features

• water pressure resistant (up to 0.5 bar), if applied in 2 coats in a total thickness > 20 mm
• fiber-reinforced
• good stability on walls
• very good bonding strength
• high compressive strength
• sulphate-resistant
• as waterproof render and basecoat for post-applied waterproofing products
• also as levelling/patching mortar
• layer thickness in one layer: 10 - 15 mm and in two layers: max. 25 mm
• for mechanical and manual application

General notes

• Limits of use: do not use weber.san 164 in immerged areas without application of a complementary waterproofing, for ex. the 2-comp. reactive waterproofing slurry weber.tec Superflex D 2.
• Protect the freshly applied render from rain so as to avoid among others efflorescence and from too quick dehydration, in order to ensure an optimal hardening.
• Remove cement laitance (hard sinter skin).
• The consumption figures mentioned in this document refer to the minimum layer thickness of the render. Due to specific substrates and application variations the consumption might vary. Exact consumption must be determined on a job site mock-up (trial area).
• Adjacent building parts must be separated from the built-in render system.

Special notes

• Do not add any foreign substances during mixing and application.
