Product features Universally dispersion primer Prevents the formation of ettringite Rapid drying Concentrate - can be diluted with water at up to 1:3 creates a very strong bond between substrates and subsequent tile adhesives and levelling compounds regulates the absorbency and protects substrates from the mixing water from mineral mortars
Advantages Prevents ettringite formation effectively with MONOFLEX-S2 enables laying of tiles and slabs on 'green' calcium sulphate screeds protects sensitive substrates (e.g. wood, calcium sulphate screeds) from the mixing water from the tile adhesive
Areas of application as a special primer on calcium sulphate screeds or gypsum plasters for installation with conventional SCHOMBURG tile adhesives regardless of the tile format for laying on ‘green’ calcium sulphate binded screeds up to a maximum residual moisture content of 1.2 CM-% in combination with MONOFLEX-S2 for tile formats up to 120 x 120 cm for priming non-absorbent to highly absorbent substrates For walls and floors For interior and exterior use

Preparing the substrate Requirement for substrate 1. 2. 3. 4. 5.
Load-bearing Clean Dry Free of cracks Free of adhesion inhibiting substances
Preparing the surface 1. Calcium sulphate screeds must be roughened and vacuumed. 2. A moisture measurement must be carried out using the CM method to assess whether it is ready to receive. 3. Weak or adhesion inhibiting layers must be brushed off mechanically, sanded, milled or shot blasted.
