It should be ok if you din stick any sticker or tape on it, because when u remove it, perhaps it will leave stain or peeled of the paint,

It's not just the finish coat to think about.. 

The moisture content of the painted surface will also affect adhesion of the final finish.. 

A quality sealer undercoat to prevent wasting the finishing coat (being absorbed into the dry cement)..

and correct technique.. Waiting each layer to dry properly before applying another coat..

If you're only looking at the final finish without knowing the basis then for sure it won't look as good or last as long..

will be moving into a rented house soon, some of the interior walls are not too desirable aka dirty, plan to repaint it but have limited budget

can anyone suggest what i should get? i think will just paint it white
