Plastering the ceiling with skim coats of plaster
Once this is done, then you can start plastering the ceilings with skim coats of plaster. This is the in-between of the three-coat plastering and merely taping and finishing the seams between sheets of wallboard. The skim-coat method involves the application of a single, eighth-inch-thick layer of plaster over the whole ceiling surface or walls. This is a compromise, using some of the qualities of real plaster with the economy and speed of wallboard.
This is probably the most difficult part of the job technically. If you don’t put the layers of plaster on smooth it increases the amount of sanding exponentially. So, the key here is to properly skim coat the ceilings well to minimize the amount of sanding you will need to do after.
When doing so you may need to repair any major damages were scraping.
Sometimes this can be as easy as applying drywall tape in the worst areas, or just putting more plaster on depending on the situation. Regardless, the goal in this step is to apply a good surface so you can sand it to perfection.
Top coat plastering, or skim as it is known, is a very tough task undoubtedly. It is not difficult, in fact, to get it on the ceiling or wall; however, getting it smooth and flat needs a lot of hard work, practice and dedication. You wouldn’t want to end up searching how to remove textured ceiling plaster as it may go wrong, right?
