Plastering & Rendering

New bathroom - old lathe and plaster walls - patch repair and skim or replace with plasterboard?

Anonymous user 28 February 2024 - 3.02 PM

I live in an old flat and I am getting a new bathroom installed. There is a shower above the bath which is currently tiled + sink splashback. new tiles will be installed at the same location as the old. The remainder of the walls have lining paper on and are painted. The lining paper will be removed. The skirting boards need to be removed. Do you think it's best to only remove hollow sounding plaster and patch then skim OR remove all lathe and plaster and re board and skim? Are there any tips to predict if the wall likely crumble when the lining paper and skirting boards are removed? Advice on the best course of action would be greatly appreciated. My flat was built in approx 1900.

you will find the tile's adhesive will have the strongest bond and the old plaster will crumble. Is the same with old wallboard. It is hard to tell and a tradesman would only estimate as the structural quality of the fabric will only be revealed fully during demolition. If it turns out to be hard to remove it is probably sound. If not get rid of it. More work early on will render better results and make the job mroe cost effective and easier in the long run, by that I mean achieving a top finish will be smoother with the proper prep. hope that helps regards Guy

Hi If it was my own bathroom I would remove all the old lathe and replace with plasterboard, then have skimmed, slightly more in cost and a lot more mess but would give you a lot better base to start your new bathroom from. You would also have a lot less problems with the walls and ceiling in the future. Phil

Hi there, I would advise to remove all old lath and plaster, re-plasterboard and skim. If you are taking off tiles, stripping lining paper and taking off the skirtings/facings you will find that a lot of the plaster will come off with that and it would be almost as much work repair than to replace without the guarantee of longevity. Yes, it may cost a tad more and it may be a little bit more messy but worth it 100%.

hi,its all down to how much mess and cost you want.if you have the money and want a lot of mess strip the lot or,if the plasterwork isnt too bad,even if you find loose areas when tapping,leavewell alone.unless it is falling off.if you have clearance you could stick new moisture resistant board over the top giving you a nice new finish for you to skim or tile on to.certain wall like the door wall will not allow for board thickness due to loss of architrave around door,this wall will have to be made good by patching.the other 3 walls can be dot and dabbed and plumbed using level.also you will have no mess to bag and skip.ps,dont forget to pva walls before sticking on boards,at least 2 coats.or again if you want more mess use thistle bond it ,though expensive and unessesary
