Being a total newbie to plastering we (wife and I) have got into a bit of a bind. We are refurbishing a bathroom in our recently aquired 1950's bungalow. The tiling has not been touched in 30 years and was in a terrible state. Removing them tore off the wallpaper(!) underneath and removed the finishing plaster. When we removed the basin half the plaster on the wall fell off. The remaining plaster was blown and came off with very little assistance.
Underneath we found bright white concrete bricks (ordinary house brick size) that are very very porous. We treated them with lots of 5 to 1 PVA and applied bonding plaster at 10mm depth over 1 sq. metre.
The result is an area of plaster that is crazed with random cracks every 30 mm or so, adhesion seems O.K.. We plan to 100% tile the bathroom
Questions are:-
1) can we leave up what we have done?
2) can we tile straight on to this plaster without a finishing coat?
3) what did we do wrong and what should we do to put it right on the rest of the bathroom?
Help please!!
