Hi, I'm looking for advice regarding my friends project. She is turning the old outbuilding at the bottom of her garden into a home gym and has been painting the floor, lead by the instruction of the person that has been doing the work for her. He told her that she would have to seal the floor with PVA; which he provided. He approved the paint that she was going to use, gave her guidance as to how to do it and assurance that if she followed his instructions, it would turn out well. Having followed his advice, my friend is now finding that the paint (Leyland Trade Heavy Duty Floor Paint) is scratching off extremely easily. We took a look into the paint in question and it seems that they don't advise using it over PVA, for this exact reason. We are where we are. What do we do now? Any advice would be much appreciated.
