We have a new ceiling! Our plasterer arrived early Wednesday morning and attached blueboard to the beams. Blueboard looks more gray then blue and has special absorption qualities that aids plaster in adhering to the surface and not peel away versus using dry wall. After the blueboard was hung, mesh tape was applied to each joint and then a scratch coat was applied over the tape. The scratch coat dried for about 45 minutes and then the base coat got mixed up with water.
This is where the process got a little funky; the base coat (we used Imperial Basecoat Veneer Plaster) was our final coat—normally you would add another layer of plaster. Under the recommendation of Pierre using just the base coat would give our ceiling a look that was similar to our horsehair plaster walls. Pierre felt the second coat would make our ceiling look too polished, smooth and modern. Above and below photos of the ceiling in progress.
