Application

Primer underneath subsequent layers of polymer-modified bitumen thick film sealants such as Köster Deuxan® 2C, Köster Bikuthan® 2C, etc.
Can be used as a pre-treatment or primer of new concrete to prevent free-lime egress.
Compatible with mortars, plasters, cementitious slurries and concrete (but not gypsum).
Can be used to harden sealing slurries.

Penetrating primer and liquid hardener.

Features and benefits:

A thin fluid product based on a polymer and silicate combination which can be used as a deep penetrating primer or as a liquid hardener.
Strengthens and protects mineral substrates and to reduce their absorbency, even on problematic building materials such as sandstone.
Decreases salt efflorescence and free-lime in new developments and increases the resistance of mineral substrates to freezing and thawing.
Increases chemical and mechanical resistance of mineral building materials.
Has strengthening and hydrophobing properties.
