1 Normally, raking of all joints of the walls to be plastered should be done at the time of doing masonry work itself but generally, it is not done at that stage. Before plastering, get all the joints raked with a hook to give a better bond to plaster. Don't allow the use of trowel or hammer or tesi for raking of joints. These tools chip off the edges of bricks. A hook is the best tool. See that joints are raked for a depth of 10 to 12 mm. Thereafter, get all loose material removed. Wet the surface well and keep it so for 24 hours at least before doing plastering work. Avoid over-wetting of surface to be plastered as it results in extra shrinkage of plaster and cracks may appear in it.
