The Self Build Self Help Site wall structure

Dry Lining - continued

The advantage of a dry lined wall is that it should provide a very flat surface so that the plaster skim will also be left flat. By trapping a layer of air behind it (about a 10mm gap) it also provides some element of insulation.

The disadvantage is the aspect of fixing units etc. This requires the fixings to be anchored in the block wall, and the fixings not to be screwed so tight that the plaster board is crushed if there is no adhesive dab directly behind the fixing.

The plasterboard can also be crushed if not enough care is taken when applying a utility bar against the wall when squeezing tongue and grooved floorboarding together.

Dry lining does provide one other option. Instead of a plaster finish, a cheaper option is to use tapered edge board and then tape the joins and fill the joins with a soft sand filler. The joins will need a few coats of filler and sanding to get a surface flat enough to paint. This is cheaper than a plaster finish but it is very labour intensive and dusty. But, if your budget is tight then consider it. If you decide on this route then you could still call in a plasterer if you have had enough after one room! - and you haven't lost much - except time.
