just hacked off tiles from solid shower wall, set coat has come off with tile( house is only 8 years old), render in behind i thought would be like iron(like external)!! not so, side of paint scraper can rake it back to blockwork with no effort??? is this typical of a shower wall or have plasterers used a very weak mix. will nhbc be interested in this or am i dreamin. any ideas for a remedy b4 retiling:mad2::mad2::mad2::mad2::mad2::mad2::mad2::mad2:

Sounds like browning coat and plasterer forget his finish coat.

Some plasterers have been known to use soft sand (I've seen it) and it dos'nt have the strenght for rendering,internal or external. It could also be a very weak mix, a couple of options for you are, thin down some sbr about 4-1 and soak the sand and I mean soak which will get sucked in and bond the render when dry or rip the whole lot off and dot and dab with plasterboard. You could get hold of the nhbc but the process may be dragged out.

you dont want to use plasterboard in shower/area tile backerboard at least then tank as for wet room

what did you use before backerboard came along gooner?, I've been tiling for nearly 30 years and not had a problem doing it p/board and tanking. But as you say, it's up to me
