ML-PRIMER is a water-based, white or colored, silicone-acrylic primer with very fine aggregates. It improves the substrate’s roughness, thus enhancing the adhesion of decorative renders of all types (cement-based, acrylic, silicone, silicate). Furthermore, it ensures a uniformly colored final surface, especially when a dark colored render has been selected.  It is used as a ready-to-use primer, forming a coarse surface that improves the adhesion of the render to be applied subsequently. Ideal for smooth surfaces, such as concrete, cement boards, gypsum boards, etc., as well as absorbent surfaces, like the base coat of renders. It is recommended to use it colored in the same color as the render, especially when MARMOCRYL, MARMOCRYL SILICONE and MARMOCRYL SILICONE-SILICATE renders are to be applied. Suitable for interior and exterior applications. 

Substrate preparation
The surface to be primed must be dry and free of dust, grease, dirt, etc.

Application
Before application, ML-PRIMER has to be stirred, until it becomes homogeneous. Then it is thinned up to 10% with water. It is applied with brush, roller, or spray. The render can be applied as soon as ML-PRIMER has dried.
