Mud is the best practice for applying drywall corners. However, you can caulk the drywall corner, but caulk can not compare with mud projects. Caulk is a cheaper and fast method. But it has many bad side effects.

In this article, I will describe everything about caulk drywall. Let’s jump in.

Is it OK to caulk drywall?

Caulking on drywall is not recommended but also not prohibited. Caulk’s big problem is cracking, and it happens in dry weather. To protect from cracking, use a flexible caulk [ad].

Mud and tape projects also can be cracked. So there is no 100% guarantee for drywall corners that do not crack.

Use a good caulk on drywall, dry properly, then paint on it. But again, I say, quality drywall project caulk should not apply.

Do painters caulk corners?

Professional painters know what they are doing. They apply caulk if their project needs it. For example, there can be caulk in low-traffic areas, low-value areas, or very cheap projects. On the other hand, quality drywall projects, the highest traffic areas, important areas, or others should not apply the caulk. 

So everything depends on the painters. However, many of them do not like caulking.

Can you caulk where the drywall meets the ceiling

You can caulk where the drywall meets the ceiling. But it can look creepy, and the caulking surface will not be properly smooth. Don’t use too much caulk. After dry caulk, first apply ceiling paint, then the second hit with wall paint. No need to apply tape.

Can I use caulk to fill gaps in drywall?

Filling a maximum ¼-inch gap with drywall mud and tape is the right option. You can use caulk to fix small gaps between the drywall. But for big projects, many pro painters do not recommend caulking. You can not sand and not be able to fix past mistakes after caulking.

How you can fill a big drywall gap, I explain in this article.

If you want caulking and then mudding, there is no need to use caulk. Go directly mudding. If you already used caulk and it dried, do not worry. Paint on it.
