The first step towards lasting performance in natural lime systems.

Every durable wall build-up begins with a reliable bond to the substrate. That is why the bonding plaster forms the foundation of the Hessler natural lime plaster system. It enables all subsequent layers to work together over the long term and deliver the full benefits of their physical properties.

Why we developed HP 14

Reliable adhesion is particularly important on smooth or non-uniform substrates, as well as in thick-coat plaster systems.

With HP 14 Natural Lime Bonding Plaster, we have developed a cement-free bonding plaster designed specifically to meet this challenge. It creates a secure bond between the substrate and the natural lime plaster without compromising the vapour permeability or capillary activity of the wall build-up.

Suitable for use on almost all surfaces and for fixing compatible insulation systems, HP 14 is one of our core products.
