    Hi all
    I have a massive lower floor 300sq that has a new ufh screed on top of suspended beams.
    The liquid screed is fantastic and dried for 2 years and was grinded a week after laying. We were progressing well and the painter ( unknown to him) oversprayed the floor as he painted the wall.
    The floor guys came and have said that they are not wanting to put any self leveler on paint. We the scoured the floor with white viniger and water. hoovering up the excess as we went.
    How good does the floor have to be?

    You need to mechanically remove it, grind it off or get a shotblaster on it the installers are right their screed would fail.

    I`m not saying its the right thing to do, and there is a possibility of failure.
    However, commercially, this happens all the time, and normally the client is not willing to pay for removal.
    So, we latex over the overspray, at the clients risk.
    We have never had a failure due to this.
    If the overspray is flakey, thats a good indicator failure is likely. If its well boned, you might be ok.
    You pay your money, take your choice.

    Spin it off, put down a dpm primer and go over. But yes the reality is that plasterers and painters should be covering that floor. If anything fails the finger could be pointed at the flooring contractor for not removing the paint even if that’s not the reason.
    I’m sure your painter won’t guarantee the floor installation over his painted floor?
