Today we were hanging the plaster in the second bedroom. These plaster sheets are heavy, wobbly and very fragile. Bump them and the corners disintegrate, don't hold them in the right place and they wobble and snap. Now the wall was dry we just need to get them up there. One of the sheets needed to go around the windows. Instead of cutting little pieces and having to fill gaps, the plan was to cut out the holes for the windows lift it up in one piece and pray it didn't break. Happily all went according to plan- no breakages and all the measurements were accurate.
Reno tip for today. To cut plaster score it three quarters of the way through with a sharp Stanley knife then cross your fingers and snap. It should snap down the line you scored.
