plastering ceilings

[arad]

i have to patch into a ceiling that is water damaged but it is old plaster onto lathes. any ideas onthe best products to use

Cut the lathes back to the nearest joist and stick some noggins in. Cut plasterboard a couple of mm smaller than size of patch and screw to noggins / joists.

Scrim and skim.

Regards

That's what I did but fell down badly on the skimming . Doesn't matter what I do I end up with an uneven skim that has lots of holes in it. Where am I going wrong and more to the point, how can I camouflage this mess?

Have you left the skim up or did you remove it before it went off? Please tell me you removed it!

If you've removed it, get a plasterer in to blend the patch in. If you haven't you'll probably need to get the whole ceiling skimmed to hide it unless you can remove the bedged work without causing further damage.

A pic may help.

No, I left it in the hope that there might be some way of camouflaging it.

Did you PVA the area you were skimming? If not the water in the plaster is sucked out and the plaster 'goes off' instantly.

Yes I did. I ended up giving the plaster a bit of a rub down then filled in the holes and hollows then gave it a couple of coats of emulsion. Admittedly it's a far from perfect job, in fact it still has a bit of a texture to it. However, I think this texture gives it a bit of an olde worlde look. Pity the rest of the ceiling doesn't match it

In any case nobody would see the difference if they rode by on a motorbike

I look on this as a learning experience. I have learned not to bother attempting plastering again
