4. Mix the plaster

Always have someone to securely hold your ladder when you plaster the ceiling. After all, safety is the top priority. When skimming a ceiling with plaster, speck some clean water on the ceiling. After this add a small quantity of plaster to the edge of your trowel which contains the plaster to be applied to the ceiling. It will help you to create an even and thin layer. Spread the plaster in rows (about one metre long) for doing your job conveniently. And, don’t forget to take sufficient breaks in between your project.
Also use the rough edge of your trowel when you spread the plaster. It will assist you to create scratches or scrapes in the plaster. When the ceiling is fully coated, allow it to dry properly. It could take up to 48 hours based on the plaster type you apply. Once your plaster is properly set you can use the second coat and continue using the skim coating technique. Using these two fine layers will help you to get an even and smooth ceiling.
6. Sand and smooth out the surface properly
Whether or not you are skilled at skim coating your ceiling. You will end up with a few bumps through the process. So, don’t panic and remember that it has an easy solution.

Repairing a hole or crack in the ceiling
If you need to patch up a hole in your ceiling, you’ll need to put extra efforts before you start plastering. Begin by brushing away any loose plaster particles. Then, fill the hole or crack with plaster. When you have a lath ceiling, ensure to surround the lath with the plaster. Now, leave it to dry completely.
After this, use a piece of wire mesh to cover the hole. When the wire mesh piece doesn’t stick well, secure it by using wooden dowels. This will strengthen the surface so that it remains strong throughout the project. You can also add another layer on the wire mesh. Once the plaster is set down properly, cut off any visible pieces of wire from the mesh. Sand down the hole edges in order to smooth and even them out.
