alright lads i,ve got a job that requires lime plastering because of moisture build up so should i just use lime in the float coat say 5 1 1 like render external but i expect i would not need to use waterproofer in the scrach just feb is this right, i ain't done any lime inside before cheers
 
dont take this the wrong way mate but it sounds to me like your not in possesion of all the relevant information regarding this job...

im gonna take a guess at one or two things...
its either the wall needs to breath e.g. its stone and lime mortar...

or youve got condensation or penetrating damp problems...

either way, using cement and a bit of lime is going to solve jack sh't...

more background info required..
 
ok right well the old pub now a house not sure if stone but some surveyer went there to value the property and told the customer as he did some test and said cut the damp parts out as it's hollow in these areas and repalce with lime plaster to allow it to breath it's in the upstairs bathroom with no extracter fan
 
the guy is talkin absolute bollox mate...
put a timed (run on) extractor fan in and be careful not to remove more than 50% of the plaster
 
And if your going to use lime mix read up on it first as no cement or admixes are required,
 
so basics fans, heat recovery systems all the way now, will take away all condo problems..
 
Lime plaster isn't sand and cement render with a shovel full of lime in mate. I may be wrong but I don't know how lime plaster will cure condensation. That's all down to ventilation hence chris' advice with an extractor.

Lime plaster done properly will absorb moisture
 
i would use limelite or dricoat and finished with high impact finish as they will not condensate

this would be easier for you than going down a traditional lime render route (ie...hydraulic and non)
 
as said above its not sand and cement with a shovel full of lime, There is hydraulic lime in 3 grades which is mixed 2-1 with sand and then there is hydrated lime.
lime helps by absorbing the rain then allowing it to evaporate rather than soaking into the wall. traditional sand and cement render is too strong/dense which leads the way to penetrating damp hence why lime is used
 
Is there a surveyors report? should specify what is required...then you have no comebacks.
