Next, pick up a regular spray gun with water and sprinkle it on the ceiling. The best thing will go if you process a small area of the ceiling with water, and then remove the whitewashing from it with a hard spatula. Having finished with one site, go to another until you completely complete the work. By the way, wet whitewashing is quite easy to remove, so you will not have problems with this. Whitewashing, which flies from under the spatula, is best to “catch” with an ordinary basin that you need to hold in the other hand. It will go faster if you take someone to your assistants.
