Can I use caulk instead of joint compound?

No. Caulk might look great for a short time (if it doesn’t shrink to oblivion right away), but it doesn’t bond to the cut end of the gypsum panel at all. Eventually it’ll crack loose. You need tape in most cases to create a solid bond (tape-on-paper, essentially), and to add structure and continuity to the joint.

Can you fill drywall gaps with caulk?

Use caulk if cracks appear where the ceiling meets the wall. Caulk is flexible and can withstand a slight bit of settlement. Sand, prime and paint the wall after you’ve repaired the crack. And then stand by for the next change of seasons and the next round of drywall cracks.

Can you put caulk on drywall?

If you’ve got thin cracks in your drywall, you don’t necessarily have to break out the drywall compound to mud the area. Caulking drywall is a much faster and easier way to repair those hairline cracks. No matter what type of caulk you’re using, the caulked part will look off and the paint will be easily discolored.

Can you use silicone caulk on drywall?

Silicon caulk sticks extremely well to drywall and will soak into the layer of paper. Then, apply joint compound (also called drywall mud) with your putty knife, applying a very thin coat (1/8 inch or less) with your drywall knife or scraper. Wait overnight for it to dry, and sand it down to prepare for finishing.

Can I paint drywall without mudding?

Always properly tape and mud drywall joints before you paint. Skipping the step of properly sealing joints in drywall not only will make your painted space unattractive, but unsealed drywall is also often against building code in homes and attached garages.

Can you fill ceiling cracks with caulk?

Use an adhesive caulk, or a pliable caulk, to fill the cracks. Put a bead of this caulk in the joint and press it in with your fingers. It is the only thing that will fill such small cracks. The caulking stays a bit pliable, and will expand and contract with any movement of the ceiling, keeping the crack filled.

Can you use caulk on walls?

Acrylic latex and silicone blends are the ideal choice for most indoor areas, including along walls and baseboards. These types are far easier to use and remove, even though they can shrink over time. The biggest benefit is that you can paint over this caulk.
