Having started plasterboarding today I've realised I have some fairly basic questions.
I understand it's good practice to avoid lining up board edges with the edges of openings- much as you would do with the frame sheathing. But I can't do this unless I cut a board in half lengthways. Is it really a good idea to add an extra floor to ceiling butt joint (and a messy cut edge meets tapered edge joint, at that) just to avoid having a tiny joint above a door??
Secondly, how important is it to leave a gap between the boards and the floor? I get the point where you have an old house with a potentially damp concrete floor, but this is a suspended timber floor.
Third, any tips on getting a good finish in places where I am joining cut boards, or cut boards meeting taper edge?
