My mate had some damp in his house, hes removed the old plaster and had it damp course.

Now can I re-plaster back onto the brick work, or would i be best putting plasterboard up first? He has gutted the room out so isnt to bothered what goes on.

Or, can I use the bond on the brickwork then multifinish that?

What would you recommend?

personal choice really! remember to pva the brickwork before bonding.

it would be much easier for you to dot dab/ line though.
 
Gypsum based undercoats will draw out any residual moisture and salts left in the brickwork, so not the best choice on a wall with a known damp problem.

so you just recommend dot and dab then.

Havnt done any for years, what product should i use as an adhesive.
 
It would be a mistake to dot and dab onto a wall that has/had a damp problem,, unless you can be absolutely certain it has been cured. Salts, as well as damp will come through the dot and dabbed boards. We had a photo on here of such a wall two or three months ago. If you were going down the p/board route, I would strap the wall with timber, add insulation, and then screw on the sheets ( foil backed). If you wanted to re-plaster back onto the brickwork with Gypsum based undercoat plaster,,, scratch coat the wall with a 4 sand to 1 cement with plasticiser/waterproofer added to the mix,, and you will have no problem with efflorescence etc. As long as the "cause" of the damp is cured though,, that's the main thing.

Or you could use Duplex foil back boards but you can't dot & dab those.
 
thanks for that roughcaster.

thinking out loud, i think this is too much for an amateur like myself. May be an idea to get a professional in for it.
 
How would you fix them?
Screw into timber wall battens; but I have screwed directly to a porch brick wall using through frame fixings as there was not enough space at the window frame for battens; would have ended up on the glass! Multifinsh skim & 2 years later job is still good.
 
ok great thanks.

Also, abit off topic, ive seen some americans just fix plasterboard and not skim, whats the advantages/disadvantages of this?

It’s also used here in the UK but mainly for industrial buildings; OK for a partitioned office environment but, in my view, it will look total carp & shout DIY bodge in a residential property. You will spend a lot of time filling screw heads & joint scrim between taper edge boards &, for a novice, this can be nearly as difficult as skimming the boards if you want the joins to remain invisible. It may seem like a good alternative if you can’t plaster & are baulking at the cost of hiring a spread but it will always shout “cheap DIY”, is more easily damaged & if it’s been papered, chances are you’ll never get it off without damaging the boards; :cry: skim it or hire someone who can! ;)
