KLEIB G5 Bonding primer is a ready-to-use preparation based on polymer resin for priming interior and exterior substrates before application of floor levelling mortars, joint compounds or adhesives for ceramic and stone tiles. Particularly recommended for use on smooth, poorly absorbent or non-absorbent substrates, such as smooth concrete, plasterboards, OSBs, terrazzo, ceramic tiles and dados. Thanks to the quartz aggregate content, the product creates an appropriately rough and coarse bonding layer on smooth and slick substrates, thus facilitating application of subsequent finishing layers. The product improves adhesion between coatings. It is water-resistant and has substrate-curing and adhesion-enhancing properties.

It strengthens substrates and improves adhesion to demanding surfaces (smooth concrete, plasterboards, OSBs, terrazzo, ceramic tiles and dados).
