3 day process.
Day 1 rip out
Day 2 first fix plumbing and electrical
Day 3 plastering
Now we leave it for 2-3 days until the plaster is pretty much dry before we start fitting units or painting.
Painting is best done before the units are in but being on a tight schedule normally means fitting some units while the plaster is only just dry but not dry enough for paint.
Sometimes the painter will come in and give the walls a base coat while covering the units with dust sheets.
