forgot to mention, I'll be installing tiles on the entire area afterwards, so plywood may not be a sound choice?
overlaying 1 inch of concrete
living room floor kind of has two levels, one surface is about 1 inch higher than than the other. I want to put on an other layer so the surfaces are level. what kind of cement should I use. For prep work , should I scrub the surface with some acid solution or do I need to grind it? The surface seems to have some kind of paint (see attached). thanks
