KÖSTER Polysil TG 500


KÖSTER Polysil TG 500 is a thin fluid product based on polymers

and silicates. On salt-burdened and 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.

KÖSTER Polysil TG 500 also has strengthening and hydrophobing

properties. The material is compatible with mortars, plasters,

cementitious slurries and concrete.

Features and Benefits:

  • Reduces the risk of further salt efflorescence development.
  • Raises the resistance of mineral substrates to the freeze thaw cycle.
  • Can be used a primer beneath polymer-modified bitumen thick film sealants.
