As you can see from the pictures, I have had an issue with the window reveal in the bathroom. The reveal is plastic, and has been tiled before - the score marks were made by the previous tiler.
The two tiles that today fell off were stuck on on friday.
I have hacked most of the plaster off, but the plaster around the window was new and sound, so what I did was hack off the old plaster and fill i the gaps with a board, then overboard the whole lot - in effect making the wall slightly thicker.
The plastic reveal is at an angle of around 75 degrees to the wall. So to straighten it off, when I dot n dabbed the surrounding wall, I extended the plasterboard over the window reveal slightly, to get a good 90 degrees to the window frame. So now I have a deep recess to get my tiles over. I originally stuck the tiles on with a good chunk of adhesive (Mapestick). But when they fell off it is still wet at the back!
An idea I had was to stick a piece of tile onto the deepest part of the reveal, then stick the proper tile over it. But I have a feeling the real problem here is absorbency of the plastic reveal.
Any tips? I could do without taking off the reveal. It was tiled before, for 9 years. I think they used cement though.
