Without question use a sharp sand render base coat 3-1 with integral water-proofer, once it part sets apply a coat of 4-1 building or plastering sand with clean water. Multifinish top coat. Certainly not hardwall or lime plaster. Both of these products will absorb moisture from the brickwork and transfer it to your plaster top coat.

You will need to re-plaster over a DPC in a cement based product,not Gypsum based.
I use Thistle Dri-Coat.

you'll need a sand cement render with an approved integral waterproofer added while mixing and finished with 2 coats skimming. ideally 1200mm high on all injected walls. hell of a job if you've not plastered before.

There is a special plaster required, you will find it on the shelf at major DIY stores like B&Q...this will be the base coat which can then be skimmed over with Multifinish.

hi the best thing to use is a sand and cement reder
first coat a 3-1 sand and cement with added waterproofer
second coat 4-1 sand and cement renderwith added waterproofer
then skim the wall.
the dpc takes a while to cure so the sand and cement with the waterproofer will keep things dry till the dpc cures.
hope this helps

Depends what you have actually taken off, if you are back to brick then the render needs to be re-rendered or use thistle hardwall, leave it set back from existing plaster, wait for it to go hard but not dry and then skim with multi-finish ( 2 coats ). Not something that you can do as a D.I.Y' ER, certainly wouldnt attempt without experience. Get some quotes.

Hi Imran

you need to replaster using a hydrated lime(renovating) plaster.

Hi Imran, The associated rendering and plastering is crucial to the success of the dampcourse.I would strongly not recommend diy work or the work carried out by somebody on the cheap.I would recommend hiring an honest professional plasterer.It would have been in your interest to use the company who installed the dampcourse,to also undertake the rendering and plastering.Your guarantee if you were offered one would then be fully valid.Best wishes
