Prepare your clean, water sprinkled surface area
Make sure the wall or surface you are plastering is clean and has no loose dust particles on it. If you are working on a ceiling it needs to be made rough by chiselling before you plaster it and you must ensure that all shutter oil or releasing agent used on the shutter work is completely removed.
It is also very important to ensure that all of the building’s electrical work has been completed before you get started because once you have plastered, you close the door to run additional wiring. This consideration covers all of the electrical pipes, boxes and water supply pipes etc. that are fixed according to drawing or requirement.
Also check at this stage that there are no leakages in the wall or surface as plastering should only be done after fixing any of these problems.
Once you have these three checkpoints completed you are nearly ready to get your plaster mix preparation going but remember that when it comes to the surface area, you can sprinkle water on it to help the plaster stick that bit better. In fact, the surface should be well cured for Step 4 so that the wall does not absorb the water from the mix.
Due to efflorescence, a handy tip is to NOT use salty water.
