Iv got some salt coming out of some plaster under some stairs. On a new build. Bonded and board finish. There is also salt coming out of some left over board finish, that was put on a bag? Is this a fault with the plaster?

Thanks

Sounds like it was put on thick. If you put finish on too thick you'll get a layer of efflouresence. I tell customers to wait until fully dry, scrape off and it will be fine
