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.
