I know this isnt the done thing but has anyone skimmed over bathroom tiles. Someone wants me to do this on a property they are going to rent out.I have never done this and know it is wrong but this bloke works for a company that gives me work so i want to keep in with him.I told him they need to come off but he isnt having none of it.Anyway has anyone done it and if so how do you prep,would you wba day before and skim or tight coat of bonding.I know its bodging but i got to do it.
