What type of caulk is used for sealing gaps around drywall?

Silicone caulk

Acrylic latex caulk

Acrylic latex caulk is especially suitable for sealing gaps around drywall due to its unique properties. It is easy to apply, dries quickly, and can be painted over, allowing for a seamless finish that blends well with painted drywall surfaces. This caulk is also water-based, making it easy to clean up with soap and water before it dries.

Additionally, acrylic latex caulk remains flexible, accommodating slight movements that may occur in the structure without cracking. This adaptability is crucial when dealing with the natural expansion and contraction of building materials, ensuring a long-lasting seal around drywall.

Choosing acrylic latex caulk is a common practice in drywall installation and finishing, making it the preferred option for achieving professional-looking results in interior applications.
