Introdução
It is very important to understand that a crack in drywall, specifically in the ceiling, could indicate structural damage. Be sure to check the framing of the room and fix any problems before fixing cracks in your ceiling.
O que você precisa
-
-
Use a utility knife or five-in-one to remove loose paint or drywall from inside the crack.
-
Don’t gouge the ceiling but firmly scrape parallel to the crack. Scraping perpendicularly to the crack will only cause more damage.
-
-
-
-
After the compound has completely dried sand down any ridges that resulted from the putty knife.
-
This step will be messy! Everything in the room will get some dust on it, so either use dropcloths or be ready to clean when you're done.
-
Also, be careful not to get dust in your eyes, or inhale dust. You may wish to wear goggles and a dust mask.
-
Don’t sand into the tape.
-
You still want the compound to cover the tape and its contours completely.

It is important to note that a crack in drywall may indicate a more critical problem with the framing in your walls or ceiling. Please do not assume that this repair will prevent further cracking.

I just rocked my third ceiling. The first looked like "before" in some spots; the next 2 are flawless. The secret is to put on very thin layers, and lots of them. Of course this takes a long time to dry each coat. But if you put the mud on thick it will shrink and crack later, plus you have a lot to scrape off and then you still have to fill in low spots.
If you use a sponge first, you can end up with a lumpy mess. Level it with a 12 inch knife until it's nearly flat, then on the last coat skim it over and smooth with the sponge.
My popcorn ceiling has peeled. I took away those rough edges. Can I spray on the popcorn ceiling. It's just small sections.
