I am just embarking on a huge project that has been in the planning for many years and I have a number of questions in relation to retiling damaged walls in a bathroom. J have had the bath removed to make way for a shower enclosure and hand basin and having a new bath installed to another wall. However has with most DIY nothing is straightforward. I have removed the tiles and I could do with a little help.
Having taken the bath away 19” up the wall is nicely plastered and skimmed then there is a gap of plaster about 1 inch deep by about 2” high on all 3 sides of where the original bath sat. On the long length of where the bath sat, the wall leans back in one corner and goes out by 1 ½” by the time you get to the top. It isn’t that the wall has moved has when the house was renovated some 40 years ago which is before my time, they had added pieces of tiles starting half way up the wall in the corner it starts has a slither which widens to 1 1/2” wide by the time they reached the ceiling. The main long wall would of been an outer wall to a building built in the 17th century in brick which was plastered and skimmed then tiled above the bath.
An additional problem is that when taking off the tiles it has also taken off some of the plaster and skimming, in some places to a depth of ¾”. I was anticipating trying my hand at skimming the wall but now I think I need to do something more drastic.
My other problem wall is one of the return walls which is plasterboard with a thin skim on it. These tiles came off quite easily but it has left a lot of the adhesive behind. Will I need to remove the adhesive and what is the best way or do it? Or do I just do a thin coat of skimming.
Am I correct in thinking I should use a thinned down coat of PVA before the skimming or is it before I put any plaster on the wall to fill gaps and possibly build up the wall in the corner that is way out?
If the suggestion is as I am thinking and that is to re-plaster the gaps, holes and building up the leaning wall what mix should I be using in the bathroom?
And any idea as to how long I will have to leave it before tiling?
Is there some sort of seal that I should be putting on the skimming once it’s dried out seeing that part of the shower enclosure will be on the main wall and part on a new studded wall.
Has you have probably guessed I am a novice at this. I have done a very small amount of plastering some damaged plaster in the past and do my own decorating but this is a completely new venture for me. So please if anyone is kind enough to send any much needed advice please put it in laymen’s terms that I can understand. I have already purchased the tiles and Unibond Waterproof adhesive for the tiles and Anti Mould Flexible grout. Luckily there was only slight mould on the previous tiling and everything is lovely and dry even after 40 years which is when I believe it was previously done.
