Advice needed on how to Repair some Plaster

chrisb1357 · 27 Apr 2010

Hi all,

I have been getting our walls ready for when we plan to wallpaper them in the next month and above our window alot of plaster has fallan off (See pic below). We have asked our local council to repair this but have been told around 9 week wait so i have decided to look into repairing this ourself.

The problem is i have never done any plaster work before so what is the best way to tackle this and how do i go about repairng the best way ready for wall paper.

Also we have another area which is on our celling near our roof hatch which leaked last year that needs replacing with plaster as its started to fall off. How is the best way to replace this and re plaster.

With small areas like that I wouldn't bother with wet plaster. Use some filler instead and sand down.

in the first pic take the wood off the wall that was probably holding the curtain pole then get a bag of one coat and a straight edge damp the wall down or use diluted pva then apply the one coat then rule off with the straight edge till level with the existing plaster in the second pic are you on about the plaster that is missing around the join between the wall and the ceiling? if so apply the one coat to this as well one coat is ideal for patching and user freindly for an amature

Cheers for the tip,

So when i remove the wood and anymore lose plaster do the following.

1, Damp wall down with diluted PVA with a brush to help it bond to wall better.

2. Mix some 1 coat plaster and then apply using a stright edge etc and level

3, allow to dry for a week or so and sand

Is the above correct

When you remove that piece of wood over the window, the best way is to split it off,, along the grain with a wood chisel.
If you put something behind it,, (a hammer, crowbar) and try to pull it off the wall,, you'll probably pull all the plaster off of the lintel,, (not good).

Your remedy for re-plastering is ok, (although for deeper bits, i'd use bonding/multi). If you do it correctly, you shouldn't need to sand down any finished plaster, but being new to plastering, if it needs a little sanding down,, that's not a problem.

You can buy a 25kg bag of "British Gypsum/Thistle One Coat" Plaster from most builders merchants. That might be more than you need for your job, but it's often cheaper to buy a bigger bag, than it is to buy a smaller 12.5kg bag of the same stuff from B&Q.

it' easy to mix, do small quantities, use a drill with a whisk in it, you can get a whisk for a couple of quid. One coat is good for sanding where as multi finish is not easy to sand.

For all you'll need for your job Chris, no problem. You just need a clean bucket, and clean water. Add the plaster powder to the water, if you haven't got a drill,, stir it with a piece of flat wood, to a creamy consistency. Just under half a bucket of water will, when the plaster's added, will give you the best part of a bucketful of plaster.

You put the plaster onto a square board called a "hawk", and you apply the plaster to the wall/ceiling with a plastering trowel.
To be honest Chris,, i think it would be better to get someone in to do the job for you. It's not a big job, and shouldn't cost much to do,, or tell the council to pull their finger out.

I'm all for having a go, but will the council be happy to do the work over somebody else's if it turns out to be more extensive ( I don't know) - maybe it is better to wait the 9 weeks or as said push them a bit.

chrisb1357 · 29 Apr 2010
