Fields of application
weber.prim 406 is used for the pre-treatment of mineral substrates or as a primer for mineral top renders when painted with organic paints (range weber.pas).
Sanding, mineral substrates can be fixed and solidified by the primer. The product silicifies inseparably with the substrate, so that it is highly permeable to water vapour and weather-resistant.
Can also be used to dilute Weber silicate-based top renders (weber.pas 460 AquaBalance/pas 461 AquaBalance) and paints (weber.pas 414 AquaBalance).
- silicifies inseparably with the substrate
- not film-forming
