Dot and Dab Cambridge Ely

Dot and dab is similar to dry-lining in that you’re applying/fixing plasterboard to a surface – a solid brick wall, a block inner skin of a cavity wall or a concrete wall. This is typically used in new builds and extensions.


Like dry-lining, dot and dab can be used on old walls to provide effective insulation. It is also commonly used to straighten out and level crooked/bad walls. The ‘dabs’ used are dollops of adhesive.


The main advantage of dot and dab is the speed with which the plasterboard can be attached. Also, a space is created between the wall and the plasterboard which is a necessity when undertaking bare-block work. Like dry-lining, dot and dab uses a variety of plasterboards.


Board types include standard wall board, vapour-barrier plasterboard and boards with a higher-density core, used for sound reduction and acoustic plasterboard. Other types include fire board (which includes glass fibre and other core additives to help protect your home against fire), impact plasterboard – designed to withstand impact and hard knocks, and water-resistant board. The newer 4-in-1 plasterboard follows recent technological advances and combines standard, impact, fire- and water-resistant board.
