Eco Cork Rendering Project

Eco Cork is a product formulated exclusively with Secil Natural Hydraulic Lime binder and free from all cementitious content. Mixed with a largely cork aggregate, this offers a lightweight, vapour permeable and environmentally friendly render or plaster.

Cork is well known for it's great thermal values and that it comes from a renewable source.

Secil EcoCork is suitable for internal or external plastering. It is applied on top of a specially formulated consolidating mortar, which is hand harled onto the wall to get a key.

After the consolidating mortar one or two coats of EcoCork  can be applied in thicknesses of 10-20 mm per coat, giving up to 40 mm thick plaster or render in total. The surface is floated after a few hours to prepare for the finishing coat. After letting the EcoCork harden for a few days, a final coat of Secil finishing mortar is applied. This can be done in a single coat of approx. 3 mm thick.

Whilst we recommend using the Secil finishing mortar externally as it offers maximum compatibility and protection, internally the EcoCork can be plastered with a wide range of materials including lime putty plasters and clay plasters. It can even be left as the finished surface and just painted.
