We have developed a plaster system that is suitable for use on a variety of substrates whose properties and moisture regime require a mixture of hydraulic properties. The plaster system consists of three different layers - the adhesive layer, the filling layer and the finishing layer. Each layer can also be used separately, for different purposes.

The use of UKU hydraulic lime mixtures instead of non-hydraulic plasters reduces the working time by about 50%. NHL plasters offer similar water vapor permeability properties to other air lime plasters, but are stronger. NHL mixtures can be used for plastering using both spraying machine and händ tool techniques. Requires less aftercare than air lime mixtures.

Plastering with hydraulic lime plaster usually consists of three layers. This guide is based on plasters made with a moderately hydraulic lime (NHL 3.5) and a sand mixture selected according to a special sieve curve. Lime plasters are carbonised (strengthened) by re-absorption of carbon dioxide from the air and their drying and absorption process is inherently slower than gypsum plasters or the like, so the lime carbonation process should not be rushed, allowing 3-5 days per coat, depending on the system layer used.
