concrete can be strange stuff, so hard , yet will dust up .True power floated concrete is very hard with an extremely tough surface. Overdo it and the surface will break up !Its a tricky job.
best solution is to brush on a concrete hardener , about £15 a gallon.Its a chemical which hardens the top layer of yer concrete, tougher than pva.You can get it at most builders merchants.Make sure you are happy with the surface before you paint as the paint may come off if its still flaky.I bought a new house in 92 which had a dreadfully dusting garage floor. Used the hardener and then simple B & Q floor paint. Protected with carpet , its still great 20 yrs on !
