Wait until the scratch coat is firm to the touch—about an hour—then mix up a new batch of plaster to a slightly thinner consistency—closer to that of buttercream frosting. Use a plastering trowel to smooth the mix flush with the wall surface; scrape any excess off the wall. Wait another hour for that coat to set.
