I have pre-cast stonework on my front steps I painted white last year
with some exterior paint. Now the paint is flaking badly. What’s the
best paint for this kind of material? Do I need a primer?
Thank You

Normally I would not recommend painting concrete steeps. Can you say
Slippery When Wet?
To me successful you need to start with proper surface prep. That means
100% clean with no pre-existing paint of any kind. You need to use a
product make for that use, not just painting concrete, but concrete that you
are going to walk on. Then you follow the instructions with that material
110%. The prep is not easy, but there is no way around it.
I would use a two part garage floor epoxy. Use some sort of anti-slip
additive, whatever is approved by the manufacturer of the epoxy.

Actually, it's not the steps that I painted. I painted the concrete
banisters. They are about a year and a half old. I painted them with
plain exterior paint I got from Home Depot. I don't remember the brand.
I didn't paint the balusters. The company made those very white (which
is what I wanted). I couldn't, however, find any bright white banister.
Which is why I decided to paint them.
I found a picture online that looks nearly identical to what I have:

About 6 months old when I painted them.
I cleaned it with plain soap and water. I didn't treat it prior to
painting, if that's what you mean.

Even though sealing moisture is not your goal, Dryloc should perform well.

| The concrete was probably to new or hard to paint , a good quality latex
should have been fine, scrape it all off and let it weather or acid wash
it.

Poor prep may well have been the downfall as opposed to bad paint.
Concrete with a good layer of efflorescence would cause paint to fail early,
acid washing removes this loosly adhered mineral layer and increases surface
area for a better bite for the paint to sink into.
Residual mold release (if it was used at the factory) would have compromised
adhesion and unremoved mold flash (messy bits at mold seam) would have
broken off and opened holes allowing water behind the paint sooner.
Cant really know for sure from here
