I think my wife thought I was crazy when I told her we were going to run our own plaster crown molding… But we are going to give it a shot.
The plexiglas knifes were attached to the custom wood guides.
We then attached 1×2 strips to the ceiling to run the guides along.
And finally we installed a grid of screws protruding from the drywall to give the plaster something to anchor onto.
It was great to have help from my sister-in-law & husband, thanks guys! And here we go applying plaster to the ceiling.
And this is what it looked like after 2 passes of applying plaster and running the knife over it. We used 20 minute quick setting joint compound for the plaster.
On item that quickly became apparent was that the 1/8″ plexiglass was not going to be strong enough when pushed against the plaster if it was already setting up, so I made new profile knives out of 1/4″ plexiglass. These new profiles are much stronger and more rigid and so far have been working great.
And here we are after 3 passes. At this point we switched to 45 minute quick setting compound to give us more working time with our pot.
And after 4 passes…
It’s getting close. I am hoping just 2 more passes will do it. Then once the main runs are done we will take down the wood strips and fill in the corners.
