How to use a plasterer’s brush

			A plasterer’s brush is for roughening the plaster ready for the final coat.

			It creates a surface for the next layer of plaster to be keyed in to. Keying in is where the plaster is pushed into a gap or hole so that it ‘grabs’ more efficiently and locks (like a key).

			Step 1 – Grasp brush The plasterer’s brush is held on the palm of the stronger hand, under the strap, and held in place by the thumb and another finger.

			Step 2 – Drag brush across surface It is then dragged across the newly applied surface whilst applying light pressure.

			Step 3 – Continue across whole area Continue this across the whole surface, until you are left with a completely scratched coat.
