Hi, I've removed a load of tiles from around a bath and have been left with areas where the skim coat was pulled off the sand and cement undercoat:
Bearing in mind I'm a DIYer, what's the best thing to do here? Ceramic tiles are going to be put on after so it needs to be firmly attached to the wall. Also, I can take my time, so can do bits over a number of days.
I was thinking of filling the holes with either finish or bonding, waiting a few days, and then skimming the whole lot.
But where I get a bit unstuck is how to do it (ie do you pva S&C, and should I use WBA for ultimate grip even though it's only meant to be used on low suction backgrounds).
Any help would be appreciated.
