What is best type of paint to use on a cement block wall?

Answer 1

the right way to do it is apply blockfiller first, blockfiller is a thick acrilyc water based paint that can be applied by roller and brush. it fills all the cavity's so you can obtain a uniform appearance with the finish coat(s). then you just need to decide between flat,eggshell or semi-gloss finish.(assuming it`s an interior wall) flat hides defects best but is not washable. that can be bad if you have small children! eggshell has a little shine to it but is washable. (i`m a commercial painter and this is what we usually use in office`s school`s etc. where there`s high traffic.) semi-gloss has the highest sheen and is washable but usually reserved for trim (doors, frame`s base etc.) as most people don`t like glaring walls. for an exterior wall blockfill then you have the same choice`s to make just with exterior paint.all blockfiller is good for int. or ext.
