What is dot and dab dry lining?

Dot and dab is a method of fixing plasterboard directly to brick, block, concrete or suitable masonry using drywall adhesive. The adhesive is placed on the wall in a pattern of small dots and larger dabs. The plasterboard is pressed into position and adjusted until the surface is level and straight. This method is generally quicker than building a timber or metal frame and normally takes up less room. It works best on stable, dry walls that are not severely uneven. A small cavity remains behind the boards, although the available space for cables and pipes is limited. Dot and dab should not be used to hide active damp, loose masonry or serious structural defects. Traditional stone walls may require a different approach.
