Dry Lining
What is dry lining?
Dry Lining is the art of fitting plasterboard to either timber/metal stud or brick walls (dot dabbing) in which plaster will be applied to the board to give the meeting joints in the plasterboard a 'finished' look. They can either be taped and jointed or skimmed. This type of wall is also commonly referred to as drywall.
Joint Taping: Rather than skim over the entire wall, plasterboards are put into place that have special 'tapered edges' that dip slightly at either side. When two boards meet side-by-side then both tapered edges on each board can be filled to create a flat surface. The tapered edges are filled with a special Gyproc joint filler compound (by British Gypsum) that sets usually within the hour. This requires one or two coats of joint cement which generally takes longer to dry but gives off a better smooth finish when sanded.
The advantages of having joint taping compared to skimming is the amount of time it takes to apply to the drywall. A skimmer would require you to cover the whole area of the board but the joint taper only requires you to fill the tapered edge and overlap slighty with the joint cement.
