BEECK’s – Design - When is it safe to paint new lime plastered/rendered walls?

This will depend on atmospheric conditions including ventilation, temperature and humidity as well as any background moisture within the substrate which will migrate out through the plaster.

As a general rule, you can apply limewashes more quickly while the background is still ‘green’ this will have the effect of the limewash ‘frescoing’ into the plaster – although this is not advisable with darkly pigmented limewashes such as olive, strong red and blue where the moisture in areas may cause streaking.

Leave fat lime plasters 4-6 weeks before applying clay paints and 4-8 weeks before applying BEECK's silicate paints. Onto proprietary pre-mixed hydraulic lime plasters such as the EcoCork plaster system, the surface may be able to take a clay paint after a few days to a week.
