Tynk 920 serves as a base for plasters 921 and 922 in the renovation plasters system, and is applied on surfaces with medium to high exposure to the effect of salt. Thanks to its high porosity, it absorbs and retains the salts migrating from the groundwork.

The product is particularly recommended for renovating and maintaining historic monuments.

Product conforms to WTA guidelines

Suitable for machine-spray application (with double mixing system, e.g. DUO-MIX by M-TEC), as well as manual application.
