I plasterboarded and skimmed the internal walls of my garage about three years back and one of them is suffering with damp and causing unsightly marks and basically make the plaster and boards soggy. I'm going to pull it all down again but how do I remedy it?It's just a room a use as I gym but I like it looking clean and tidy rather than exposed or painted brick. It is a single skin wall.

I would clean it all off and tank it with vandex then plaster with sand and cement waterproofer, nice neat float finish

Single leaf water will pass through bricks if they get alot of rain on them anyway as they arent waterproof so maya lad be no visable problem to find,check external pointing for cracks,joints not filled correctly first.
Flat roof? Check roof for splits in felt,fascias ,gutters for damage,possible rubbers on unions etc.
A lad reckons he sorted his damp by mixing sbr and cement neat mixed together as a paint two coats opposite directions,says cured his damp,cheap and easy,dot and dab foil,insulated boards

I've looked on the outside and there's no obvious holes or anything that suggests excess water will come through . I think it's a case of it being single skin and it being inevitable that moisture will come through. I just wanted a way to deal with it as much as possible. I don't expect a perfect solution (it's only a garage after all) but I wanted the best possible solution considering the circumstances.
Yeah the boards were dot and dabbed on.
Would you put a membrane between the batons and the wall?
Ive never used this, so would you blackjack the internal wall then baton and board? Or would this need to be on the external wall?
The foil on the Kingspan should solve that
S a plastering

Do what Flynn says top idea just put some damp course behind the batons if you wish won't do any harm

Agreed ^^^^
I did a Chapel of Rest that was suffering from the same problem. Bedded some damp down on silicone to keep it from moving about. And built a stud work off that independent of the existing wall. Then 50mm kingspanned in between it all and put 27 mm thermal laminate board over the top with some air vents in and skimmed it up. Came out lovely, and cured the problem.
