Good afternoon,
Thank you for your question.
Dryzone® Hi-Lime Renovation Plaster can be used as a plaster coat over Drybase Tanking Slurry, the rough coat of plaster should be applied while the second coat of tanking is still 'green'.
Dryzone® Hi-Lime Renovation Plaster can be left as a decorative finish as this offers the greatest breathability. If a gypsum skim coat is to be applied, leave the plaster to set for a minimum of 24 hours before applying and keep to a thickness of approximately 2 mm. Any other finishing is carried out once the curing process is complete, after at least 14 days. Redecorate using a non-vinyl based emulsion paint.
I hope this helps and if you have any further questions, please let us know.
Kind regards,

Is this suitable for a scratch coat over tanking slurry in a basement? Also, if it is breathable and allows moisture and vapour to pass through then would gypsum plasters become damp if used on top? Cheers
