HP 90KL Naturkalk-Lehmoberputz mit Hanf

Application Range HP 90KL

HP 90KL Natural Lime Clay Finishing Plaster with Hemp is used as finishing plaster/levelling plaster for indoors. HP 90 KL can be applied to all types of masonry and all solid, sufficiently rough old plaster.

In the case of highly absorbent substrates and very warm weather, sufficient pre-wetting is required. It may be necessary to wet the plaster with water after application. Alternatively, the application of HP 10 Vorspritzmörtel (Pre-Spray Mortar) is recommended.

Concrete surfaces must be provided with HP 14 Naturkalkhaftputz (Natural Lime Adhesive Plaster) applied with a toothed trowel. After sufficient curing, HP 90 KL is applied by spraying at a thickness of approx. 10 mm. Surfaces to be tiled must be plastered with HP 1 Kalk-Zementputz (Lime-Cement Plaster).
