How soon can I paint freshly plastered walls?

If the walls are drywall, it should be ready for paint as soon as the final sanding of joint compound has occurred. One coat non tinted primer, two coats paint, is industry standard. Find the primer at the store that is marked "For New Drywall." If walls are plaster applied to a different substrate, dry times may be longer depending on site conditions. Hope this helps 🙂

I would say between 3-4 days. Make sure you have some circulation of air, and it’ll be ready within then.

As long as the walls are prepped properly (sanded ) it can be primed straightaway …then wait do final touchups if needed …then paint 2 coats of course Mandatory!!!!!
