I just installed a new plasterboard ceiling (phew - that was a
challenge!). I'm now going to do some jointing and have a few questions
for those more experienced than I....
1) I'm going to use Gyproc Joint Cement. Is this OK as a finish (i.e.
I don't need any additional finish layer on top)?
2) I recently did a little bit of patching up on a wall. At the
joints I used joint tape (the paper kind). It seemed okay. A builder
friend told me to use self-adhesive scrim tape on the ceiling. Which
should I use - paper tape or scrim?
3) When I did the wall, I found it really difficult to get a smooth
result over the joints. I sanded by hand as much as I could but the
dried-on joint cement always had an edge to it which is still visible.
How can I avoid this on the ceiling? Should I spread the joint cement
differently? (I'm using the Gyproc guide as a basis). Should I use a
power sander to get a better result? what sort of abrasive paper would
be best suited??
As always any advice most welcome and appreciated.
