The Sanding Process
The sanding process is essential for achieving a smooth and durable plaster wall. Here are the steps involved in the sanding process:
-
Prepare the surface: Ensure that the plaster surface is clean, dry, and free of dust or debris. Remove any loose paint or plaster before sanding.
-
Choose the right sandpaper: Select the appropriate type of sandpaper based on the surface condition and the desired finish.

Sanding technique: Hold the sandpaper flat against the wall and apply even pressure while sanding in a straight line. Avoid sanding in a circular motion, as this can create swirl marks.

Check the progress: Periodically check the surface to ensure that it is smooth and even. If necessary, switch to a finer grit of sandpaper for a smoother finish.
-
Clean the surface: Once the sanding process is complete, clean the surface with a damp cloth to remove any dust or debris.
It is important to sand the plaster wall in a well-ventilated area, as sanding can produce a significant amount of dust. If possible, use a dust mask and a vacuum cleaner to minimize the inhalation of dust particles.
