MARMOFIX Haftbrücke HB-350 BETONKONTAKT is a primer used on smooth surfaces such as concrete and pre-manufactured concrete elements. It gives a coarse-grained base layer which acts as a bridge between the smooth substrate surface and subsequent layers (lime-gypsum mortars, lime-cement mortars, etc.), and thus provides a perfect anchoring of these layers to the substrate. It is also used as a base for adhesion in tile-on-tile systems.
• Strong adhesion and quick drying • Ready to use • Easy to apply • Improves the adhesion of smooth surfaces • Gives a coarse-grained base layer which acts as a bridge between the smooth substrate surface and subsequent layer
