"Skimming 32 square metres of new plasterboard — how many bags of multi-finish?"
A 25kg bag of multi-finish covers around 10 square metres at a 2mm two-coat skim, so 32 metres is 3.2 bags — take 4 so you are not short on the second coat. Scrim every joint and internal angle first, and on new board you do not need PVA; save that for old painted backgrounds where you are controlling suction. Mind the set — you have around 90 minutes from mixing depending on the room.
Always verify to current regs. On-site conditions may vary.
The stud wall calculator gives plasterboard, timber and insulation counts for partitions. Ask the Gaffer for skim, bonding and beads by area and it works the bag counts from the job you describe.
Yes. Describe the background and the finish you are after, and the checklist changes: beads, bonding and scratch coats for float and set, boards and screws for dot and dab.
Yes. On Pro you share the checklist by link or add them to a team, so the mixing and the materials are sorted before you are on the hawk.
