Need to plaster plasterboard ?

ennisjim

I am planning to put plasterboard on walls and ceiling in attic and insulate this in order to create a non-ventilated attic space (if that is the right term) with a radiator or two. Hope that it will serve as a playroom or similar when toddlers get a bit older.

I don't intend to plaster the walls/ceiling of this space (cost). However I read some advice recently which suggested that plasterboard should not be fixed too long before plastering is done because it can absorb moisture and may sag or weaken. From a self-build guide...'Plasterboard relies on the skim coat to hold it taut, if it is, left longer than two weeks, the board
will begin to sag, especially in damp weather.'

Since I was intending to not plaster at all I was wondering if this meant my idea was not such a good one, ie. that unplastered plasterboard would somehow degrade and become useless ?

Has anyone come across an attic covered in plasterboard and no plaster which has survived for years ?

you dont need to use a skim coat, scrimming and taping the joints is becoming more and more popular. there are also various types of board, with different properites, you can defo do this without plastering

If you could stretch to it , you would be better skimming your plasterboard, as it will be less prone to impact damage, from your little toddler demolition team

is it a cost thing or an effort thing?
as there are hard wearing boards available, such as gypsum duraline and fermacell
