I have nicked a corner of a bedroom to make an ensuite shower/toilet another bedroom. I am tiling the whole ensuite room, however one of the walls has is built with blockwork and plastered and has about a 10mm bow in the middle. Can I level this bow out by using bonding plaster on top of the original skim and then tile to the bonding. i.e. would the bonding adhere to the original skim?
thanks
