TO-GS contact primer is part of the Termo Organika thermal insulation system. It is intended for priming the reinforced layer before applying thin-layer Termo Organika plasters: mineral TOTM, acrylic TO-TA, silicone TO-TS and decorative TO-TD ones. It may also be used to prime smooth and/or non-absorbent base surfaces, e.g. concrete, plasterboards, wood-like panels, surfaces painted before applying the aforementioned thin-layer Termo Organika plasters.
