regrout problem

[jindru]

yesterday i regrouted a shower enclosure.it was a bit of a disaster as tiles started to fall off wall.the wallseems to have been sheeted with plywood.it flexes and doesnt seem to have been sealed with tile seal.maybe pva .the tiles seem to have been covered with minimal cement, not the wall.the lipping is bad.i refixed 6 tiles and re grouted.customer is aware of state of tiling but today there is a brown stain on one line of some grout .is this
leaching from ply?has anyone else seen this? customer is happy except for brown stain .any suggestions?

IMHO it needs a complete rip out and start again, properly.

Thats a sort of resin in the ply thats leaking thru, ply has got damp..

As above, rip out.

i had a similar problem, i was called to sort out discolouring from a repatch job done by another tiler ,as the customer didnt want to call him back. turned out to be a felt tip that hed been using to mark the tiles ,

i agree rip out and start fresh

i agree rip out would be the best solution.but customer is well fed up with previous tilers making cockups in her expesive kitchen and now her bathroom.two different tilers.she just wants a tide her over job to tidy up till she plucks up the courage to try again.i know events may force her hand ie the tiles may all drop off but she just needs a bit of time.i have every sympathy.thanks for your input'
