Replastering old house

[oxygen]

Hi. If anyone has replastered an old house, I hope they can advise on this.
Bare with me, I have 0 plastering experience.

I am replastering an old house. It recently got rewired, so all the walls are chased. Any of the internal external walls are getting the dryline insulation. Its the remaining walls I'm concerned about.

There are several layers of paint on each wall. Most plasterers Ive talked to have told me the best option is to plasterboard each wall and reskim. However, this will add a half inch to each side of the wall, so Im not keen on doing this.

Do the following options sound viable?

- On walls, sand down the layers of paint, or even use a chemical to clear the paint. Under the layers, there was a decentish plastering job done.
Use thistle bond on this, and reskim that.

- Board the wall with a considerably narrower plasterboard. Maybe a 10mm (does it come that narrow, and is 10mm likely to crack much when reskimmed)

thanks in advance

You need to be very careful if sanding - there's a good chance the paint on the walls of an old house contains lead.

Possibly a stupid question, and betraying my ignorance, but can you not skim over a painted wall?

Ah, the things Ive done when working on this house, Im not a bit worried about lead in the paint.

No, apparently you cant skim over paint, since it doesn't give a good surface to bond to, it will bubble up and flake away over the next 5 years

Remove paint, polybond, bonding compound, then skimcoat

Re: Replastering old houe

if your internal walls are solids and not stud, use " mushroomcap fixings" to hold plasterboard to the wall. youll need at least 12 per sheet. they come in various lengths. This will allow you to use 12mm board and no need for battons. The half inch your afraid of loosing is such a small detail compared to the amount of work your creating for yourself. Your time would be betterspent learning to plaster to save money. Thats what i did. Equally you could just remove old plaster back to wall and re-skim. I did try to remove paint on walls in my house but it wasnt worth the effort, so i learned to skim after watching a plasterer for one day.

Jezuz, one day. Thats quick. Yea plasters seem to charge huge money for their labor, for what it is. Its mostly unqualified work. Anyways, that another argument for another day.


@aulita. Ill run that by the plasterer and see if its something they can do. Thats the basic way I want it done as well.

I have to disagree with you there. Over the years I have have had good and bad plasterers working on our house and it takes skill to be a good plasterer.

You cant skim over painted walls ....Nonsense !
What you will need to do is spend some time scraping of the loose paint and as much as you can, a floor scraper first will save a lot of effort followed by a sturdy hand scraper. Dont worry at all about gougeing the walls in fact this will be a help, when you have as much of the paint off as possible take a stanley knife and run it firmly across the wall creating a criss cross pattern over the entire wall, the more the better to create a key for the skim, a good couple of coats of 3 :1 polybond over the walls and then skim with multi finish.
The jobs a good un ! and it wont come off ever

There is some form of mesh that can be fixed to the wall (cant think of the name) This will form adeqaute key for which plaster to bond. Might be expensive though not sure.

Also: If there is textured paint anywhere, it could contain asbestos, as asbestos was used as a paint filler years ago.

Expanded Metal Lath aka EML: not sure what it costs these days, you can be sure its got cheaper.

I agreed, what would you propose?

We had all downstairs reskimmed two years ago. Very good job - no cracks.
Getting upstairs done during the summer hols.

thistle bond the walls and rre skim or 9mm wallboards fixed with 60mm metal mushroom fixings. You will know how good your plasterer is when you paint the wall belive me. Learn to plaster in one day I don,t think so!!!
