      The plan for stopping a damp problem in a local stone built church is to remove the existing nap plaster finish and reinstate the original coat of lime mortar. As an architectural technician I understand the merits of lime in terms of conservation and also respect its properties as a versatile material but in this instance there will be a lot of money spent removing the existing plaster, preparing and putting up the new plaster as well as lime washing every 5 years, and all for a solution that has only a 5 year guarantee and that may not work. I would love to see the building reinstated but is there room for a modern building solution such as external render?

      The only suggestion i could give would be to use some kind of liquid based polymer as waterproofing membrane….. either inside or external… as it is established stone construction you will not have a salting issue…

      however, the use of non-hydraulic lime render would actually be the best IMHO…. but be sure to specify an initial levelling scratch coat, before applying the secondary finishing coat…. be sure to keep the mix as dry as possible while still being workable…. a common error is to make the mix as wet as cement render, thus when it dries it shrinks and cracks…. my $0.02

      I think we would need to know the church in question, date of construction, architect etc. to answer that question?
