Dot and dab was developed as an alternative to the more traditional practice of float and set wet plaster works.
The technique allows plasterboards to be securely bonded to a masonry or concrete substrate with the use of specially designed adhesive products. The adhesive is applied to the substrate in a series of dots and dabs using a steel trowel.
It is popular today with developers because of its cost and speed efficiencies. It also offers less shrinkage and cracking than traditional wet plaster practices.
