Round the bath edge - I've got 2 tiles that just don't want to stay on

Anyone got any suggestions. It's onto clean plaster that has been
sealed with a light PVA solution (as my first try) and they still
won't stick to the wall. Bloody troublesome little buggers.

They are 1/2 tiles - so not tiny little things.

Using howtex waterproof adhesive.

Everything else has gone well - just these 2.

Anyone got any peals of wisdom?


So what exactly happens? Does the adhesive stick to the tiles? Does it
stick to the wall? Do they fall off when the adhesive sets?

I knew I'd forgotten something

They start of sat nicely on the wall - but when the adhesive goes off
it appears to lift away from the wall - leaving the tile sounding if
not fully - at least in part hollow when you tap it - meaning that it
isnt' stuck.

I remove them at that point - clean off adhesive and try again - but
it only seems to be in the very final stage of the adhesive going off
that this happens - as the moisture from the adhesive has definately
contacted the wall as the plaster on the wall is left damp.

It's very odd - and a right sod.

Might have to be some no more nails on the adhesive when the tile
falls off so that the bed of it is set right.
