Suitabe for walls, counter-walls and half-timbering. Flooring and screeds. Insulating concrete for roofing. To be used with a « building » certified hemp. Before starting, always try on a small test area.
Hemp renders are applied in coats of 2-3 cm. maximum. Wait 30-90 minutes between coats. If no finishing coat with other materials is envisaged, wait 3-4 days before applying the last coat (2cm.). Consider using EcoMortar® Finish WP as a finishing coat, it is a very low capillarity natural lime mortar that will impede water ingress in the main hemp render. For painting with lime, wait for the work to dry (60-90 days) and use Uniprotect in external paint work. Don’t forget to loosen hemp if compacted in bundles.

Mixing in drum mixers
Introduce about 30 litres of water and the Batichanvre. Mix for 3-5 minutes to obtain a milky paste with no lumps.
