Drywall joints are the seams between sheets of drywall. They can be finished in several ways, but most commonly, they are either taped or covered with a joint compound. But is it possible to caulk Drywall joints? Let’s find out.
It’s technically possible to caulk Drywall joints, but not recommended because it doesn’t bond well with the gypsum panels, and it’ll cause cracks. If you still want to caulk Drywall joints, the acrylic latex type is probably best as it’s also flexible and less prone to cause cracks.
Caulking drywall joints is not a common practice, but it is possible. You wouldn’t want to caulk drywall joints because it can create a surface that is difficult to paint. Joint compound and tape create a smooth surface that is much easier to paint over.
Can You Use Caulk to Fill Drywall Joints?
Even though it’s possible to caulk Drywall joints, there are better options to choose from. But if you must caulk, you can if cracks repeatedly appear (because you installed your floor first) where the ceilings meet the wall. It’s important to note that before applying caulk, Drywall tape to cover the joints is highly recommended, and use a primer and remove additional Drywall dust to get a smooth finish. That is, of course, if you haven’t decided to hang your Drywall backward, which makes smoothening out an extremely difficult task.
Remember that caulking drywall joints instead of using old joint compounds and drywall tape does not offer a superior bond. So, it’ll eventually crack loose, especially if you’ve tightened your joints too much. In addition, paint does not adhere to caulk (even if you use paintable caulk) effectively. The paint might chip, look lumpy, and become more discolored over time. This is especially the case when you don’t remove Drywall dust before painting.
That said, using caulk to cover joints is not a lost cause. With a stable and well-conditioned home environment, caulked drywall joints can last for decades. To get the most out of your drywall, set the temperature to 68-degree Fahrenheit, and leave it as it is.
Can You Silicone Drywall Joints?
Silicone caulk is not an ideal pick for drywall installation. This is because it’s nearly impossible to paint and may also lead to unpleasant slip-ups.
This type of caulk is extremely adhesive and normally used to seal gaps or waterproof a surface. So, if you use silicone caulk to fill drywall joints, it would be impossible to remove it without tearing the drywall sheet or ripping the paint off.
Keep in mind that drywall may expand or contract as the weather changes. Silicone caulk is highly adhesive and not at all flexible, leading to cracking during drywall expansion and contraction. In addition, it will put unnecessary pressure on drywall joints as well.

Also, acrylic latex caulk is nothing if not versatile. You can use it to fix almost everything: from drywall cracks to metal joints. It’s perfect for drywall joints that may move due to expansion and contraction.
The acrylic latex caulk can be painted, which is also why it’s commonly known as “Painter’s Caulk.” Simply use this material to fill drywall joints and blemishes that you want to paint. Although you can use acrylic latex caulk on wet surfaces, it’s recommended to stick with dry areas to get better results.

FAQs:
Can You Use Caulk to Fill in Drywall Seams?
Absolutely not. Caulking might initially seem convenient, but it doesn’t bond efficiently to the gypsum panel. So, if you use caulk to fill in drywall seams, it will begin to crack within a year. You can use drywall mud and tape to create a stronger bond to overcome this issue.
Can I Use Caulk Instead of Spackle?
No. Caulk and spackle compounds are two different things. You can use caulk to fill in gaps and corners between two drywall sheets. Alternatively, a spackle compound should be used to fix cracks and holes on the flat surfaces. In addition, caulk cannot be sanded, and spackle compound can!
Is It Ok to Caulk Drywall Corner Joints Rather Than Taping?
You should never skip taping and mudding drywall corners. The caulk will eventually crack without applying at least 2 coats of joint compound and a layer of drywall tape. This will create gaps between two drywall sheets. In addition, you won’t be able to paint your drywall without tapping and priming the drywall corners first.
