Koster Polysil TG 500 is a thin liquid based on
polymers and silicates. On salt burdened and on damp
substrates it leads to a reduction of the pore volume
and decreases the likelihood of new salt efflorescence
development. It also increases the chemical and
mechanical resistance of mineral building materials.
Depending on the substrate, the product penetrates
the surface up to 2 cm deep. Koster Polysil TG 500
also has strengthening and hydrophobing properties.
The material is compatible with mortars, plasters,
cementitious slurries and concrete.
