Hi all. I've been doing a few small repairs to walls that I've been told are made of fibrous plasterboard in a circa 1930s house. A few of the boards were a bit loose so I screwed them back to the studs. This has obviously left some indentations in the wall so following the guidance of the bloke at my local paint shop, I filled these with cornice cement (as well as a few small cracks etc).

I'm getting ready to paint the room and wanted some advice on sanding back the cornice cement, as it's a little rough in spots and a little raised up in others. Having done a bit of reading here, I've seen a few comments implying that this sanding will be hard work? The "paint shop bloke" advised 150-grit sandpaper and I guess I assumed this meant it was going to be pretty straightforward.

Any advice before I get stuck in, in terms of equipment/method? Or am I wrong and will this be basic?

Thanks, and apologies but I'm a novice who figures he;'ll learn best by just having a crack (and filling it).

Hi all, this is my first time posting on here after having enjoyed reading the forums for the past few months. Having trawled through these forums and how2plaster (thanks Rod, a cracker of a site!) I still can't find a definitive answer to my problem.

I have masonite walls which have been patched with plaster and now all the old joins are starting to crack, basically the walls crapola!

If I plasterboard over the top of the walls with 10mm plasterboard I will have to change my architraves as the new plasterboard will almost be a few mm off sitting flush. Changing or modifying the architrave is something I want to avoid.

Would I be best off using Boral flexiBOARD (6.5mm) or Villaboard (6mm) to line all my walls and ceilings as then I wouldn't have the architrave problem?

Thank in advance to all those who offer their advice

We are renovating a downstairs full brick area of our home. We have had to rough-in electrical wiring and square off brick arches. As a result we have freshly rendered sections of wall were the patching has been done against painted wall. The painted sections of the wall have been painted with a oil based paint and to get a nice finish we will need to either whiteset or topcoat (3 stage process) the affected walls to get a consistent finish before we start painting so we do not see the outline of the freshly rendered sections.

My renderer has recommended a three stage process of using base coat (cornice cement), second coat and top coat with sanding in between). I am not sure if this is the best course of action to take especially since the previous painted section of the wall are with a oil based paint.

I was advised it would be better to whiteset the walls by our painter - I understand that this is a single stage process? Would anyone have an advise of based on the situation above particular with the oil based paint on the walls. Thanks in advance.

I have to batten out the ceiling of our shed as the rafters are 800mm centres. This will mean I will have vertical rather than horizontal joins... Is this a problem?
The ceiling is a 35 deg pitch.
