Make sure you have the right tools
First of all, you have to look for the right tools to start the installation. This is very important, so search the market for all the accessories. You will not have to look for any additional stuff and most of the things, such as hammer, drill machine and nails, will be available at your home.
Determine the size of your crown
An ideal size of the tin crown will be four inches, as it will fit the ceiling perfectly. However, you can choose any size available.
Remove the older crown
If there are any older crowns attached to the ceiling, make sure that you have removed them with care. They can damage the ceiling, if you try to force them off, so be gentle while going through this process.
Put marks on the ceiling
Other than installing the crowns directly, mark the wall in order to make the process simpler. This will consume very little time, but will save you a lot of trouble.
Place the crowns on the marks
Now, place the crowns on the marks and nail them until they are fully fitted. Your wall and ceiling will now look perfect.
