Hi,
Due to the lockdown I decided to try and save money by taking down the plaster inside one of the rooms of my property (6m x 4m) back to the lathes. I was advised by a plasterer on the phone that if it was his house he would take down all of the plaster, take off the lathes and use the existing vertical wooden battons to fix plasterboard to, then plaster over the top.
I have more recently spoken to a company (when I had doubts about taking the lathes off) who have said to only use Lime plaster in order to let the walls breath - however on looking into this the cost of lime plaster would be crippling for my budget.
Could anyone offer me any clarity on this situation please? Must I use lime plaster on the interior or is there another option? As you can imagine I am a little confused! The plaster is all off on the two exterior walls, but I haven’t removed the lathes yet.
Many thanks
Are you a tradesperson and able to answer this question?
Unfortunately the cost of original material needed to correctly carryout repairs allow the building to breathe and prevent dampness in older property's are far. more expensive than there modern day equivalent but unfortunately your modern day plasters plasterboards are designed to achieve different & are non breathable.
At the end of the day it's entirely up to you how you finish the walls of internally the correct materials for the age of the building or to cover up and use modern materials which may come back and bite you in the future.
Just one other thing as most suppliers are now closed sourcing any materials maybe an issue.
Good luck Alex

Hi my name is Martin I am a time servers plasterer from north Wales and in my experience in helping renervate old houses I would take of existing slats and board on top of the uprights making sure to allow around two inches at the bottom of the new plaster board so that air can serculaite through the wall.
You will find once plastered this will solve all the problems I hope you find this helpful
yes they are both right,lime plastering is exspensive [but the wall's do breath]
its more important to have the inside of the exsternal wall's in lime because that's where most damp can penertrate. I would use normal plasterboard and skim for a basic interior wall.spend your money in the most important area's of your house.

Of course lime plastering is very expensive only really needed in historical listed building unless your house is a museum or you have money to burn plaster board will not cause damp water causes damp there are also modern methods vents of and shapes size plaster boards will be fine
