Wobbly existing tiles

[Tris c]

I have recently purchased a house that I believe was owned by the 'Bodge it Brothers'. Im planing on extending the tiles around the bath (currently 1m above the bath) to the ceiling height so i can incorporate a shower, I have managed to prise the tiling strip off the edge and have found that the bodge it brothers have been at it again,

Firstly i noticed that the top edge of the exiting tile was wobbling so out of curiousity i removed the grout and popped the tile off, it came off rather easily - the reason for this being that the previous owner had slapped some paint a freshly plastered wall without a mist coat then decided to tile to this wall without giving a key for the adhesive to bond to, meaning that paint has just pealed off rather easily.

When I tile further up the wall I will give a good key into the plaster for the adhesive to stick to but im a bit stuck as to what is the best course of action for the existing tiles as I dont really want to remove whats already there. Has anybody got any suggestions?

Cheers

I think you will find taking the trim of, probably aint help . The only thing you can do is take of any suspect tile and refit them.

Sounds like you need to strip the paint.

I don't buy into the 'scoring paint' theory. That leaves a minimal adhesive to solid surface contact area.

The more I've looked at it the more I've come to the conclusion that I will have to remove and replace the existing tiles and remove the existing paint on the wall so that the job is done properly.

When tiling a bathroom I know it's best to start with a full tile in the middle so there is an even gap at each end, but is it best to start with a full tile the height of the bath and full in with a part tile at the top or try and guesstimate the height so it's even top and bottom?

Setting out depends on main line of sight and any prominent features such as a window. More than likely with most bath positions it will be centred on the length of the bath.

Normally on the height, you would start with full tile from bath and cut to ceiling. This will depend on the cut at the ceiling, if it is 15mm then you need to start with a cut at the bath. If going down to the floor you will need to factor this in too.

Some baths do not have completely flat tops and it may not be installed level, so its worth checking first as you don't want to be cutting a tiny bit off a tile or having to fill in with a massive bead of silicone...!

Part of setting out.
