How to lasterboard small areas around windows?

[justanotherguy]

Have taken off plaster on outside wall, down to brick. Am going to plasterboard (dot and daub), and have a pro come in and skim.

Not sure however what to do about a very narrow but tall area between wo sash windows, I'd say 5cm x 100cm. Do I dot and daub that tiny area as well?

Not sure where you mean; is this the reveal or should that say two? If so yes but make sure you continuously support the edges with adhesive. It's also normal to D&D PB inside the reveals, your plasterer will then fit corner beading around before skimming.

Are talking about the window reveal?
There area recessed around the permitter of your window, if your dot"N"dabbing the walls do the windows too.
Tricky little things have a square handy for your corners and a level for the upstands.

Had to look up what 'reveal' is

So, to clarify, I'm not talking about the reveal - I'm talking about a small gap between two entirely separate sash windows.

I've read elsewhere though the D&D is not recommended for outside facing brick walls, so thinking I should maybe just get a plasterer to plaster the whole wall right against the brick.

EDIT - Just to add, the 'reveal' on my wooden sashes is entirely taken up by the upper and lower sashes, and is part of the wooden boxing covering the weights/cords

Your talking about the internal mullion.
The choice is yours, if the property is correctly insulated and condensation free, no probs with DnB.

Should add then that its a 100 y/o property. Not seen any condensdation problems, but it's definitely not insulated - just two layers of brick

My personal preference would always be for a proper job; float & set render followed by finish skim but you may be better off using foil back (Duplex) boards (on battens) or Thermaline insulated PB if it's a solid brick wall.

Don't let the Building Inspector see what you’ve done or you could end up with unexpected bill if you’ve removed more than 24% of the plaster from an external wall.

BC man has already eben round - he didn't mention anything specifically about the wall!

However, I think some form of insulation would be worthwhile.

Not sure what 'float and set' is, but prseumably it just means plaster direct onto wall, and set ready for a finishing layer?

Any form of insualtion however is going to have to be pretty slim, as otherwise the windows would need deepening somehow.

 

[PrenticeBoyofDerry]

Float and set is a method used to apply a basecoat/background plaster onto brick/blockwork then apply a finish onto that.
You can buy thermal boards but this will increase the depth of the dry-lining which sounds like a problem regarding window depth, these can be fixed using batens or DnB but if the later method used should be plug fixed to wall to secure them

Maybe he’s not bothered but, believe me, some definitely are if they spot it!
