Hi,
Whilst googling, I came across this forum and after few days of reading the forum I'm more confused than before on what to do next ... so hopefully I can get some advice.
I did "dot n dab" and skimming on previous Flats where I lived ( '90+ builds ) and never had any issues, but now I bought a semi detached house ( '45 - '50 build ) and thought it's a good idea* to remove old plaster & rendering from a bedroom and start from brick...
My 1st plan was to "dot n dab" directly onto brick with standard Gyproc Plasterboard and Gyproc DriWall Adhesive then skim 2 x 1mm Multifinish coats on all 4 walls, but the more I read the more I am concerned about introducing damp/moisture issues.
I don't see any previous damp signs and all bricks look to be in a good condition but most people say ( including British Gypsum Technical Helpline) not to "dot n dab" plasterboard on the 2 Internal/External walls.
With the new info my 2nd plan was to: "dot n dab" the 2 Internal/Internal walls and use Gyproc Hard Wall as undercoat + Multifinish on the 2 Internal/External Walls; no PVA or anything else, just clean the bricks properly.
For 2 Internal/External Walls:
Reading on this forum I see that not everyone is a fan of Hard Wall for undercoat + Lime plastering fans add to the confusion + to PVA or not to PVA on bricks ( either for "dot n dab" or undercoat ).
Previous setup was: 20mm sand and cement rendering + 2mm plastering.
*wife thought it is a good idea! I know!!! please be gentle
