Understand the difference between “dry time” and “cure time” when it comes to caulking. Most products become dry to the touch after several minutes, but don’t fully cure for days. Learn about factors that determine the dry-time for caulk.
The best exterior caulk for your home depends on areas you will be sealing, the material you want to bind, the size of the gap you need to fill, and whether the caulk needs to be paintable or in a pre-made color. Most importantly, the product you choose needs to be high quality if it’s going to protect your home.
