I want to paint new concrete, does it have to be sealed first?

How long should it be cured before it can be painted and does it need to be sealed first? Does new concrete have to be etched before putting on the primer coat?I want to paint new concrete, does it have to be sealed first?
Cure time on concrete is about 30 days on average. Until that time, it will release moisture. After it has cured, the floor must be primed, then you can apply a concrete paint. Etching is usually only required when you apply something over concrete so that the two similar or dissimilar substances will bond together. A good primer will serve that purpose and since it is new, it should not be a problem.I want to paint new concrete, does it have to be sealed first?
hhmmm yeah i would seal it first or you will be using A LOTTTT of paint or primer whatever u are using...





Because the paint will soak in the concreat and wont be very good looking or you may not even see a different color..so then u would have to put on lots of coats and that would take forever and a lot of money, so seal it first then paint it.
i would seal it first then paint it with a heavy duty floor paint (if it's a concrete floor) it will need 2-3 coats for a decent finish
