Caulk can be applied anywhere that two materials join together, or there are small gaps. Caulking is most often found between windows, sideboards and wet spaces like kitchens and bathrooms. Damp areas like these require a sealant that is mould resistant and watertight, such as silicone-based caulks. Caulks are often categorised by their intended application.


Other common areas that you can caulk are exterior windows and doors to your property. Many caulks are now able to be sanded and painted over, making them easier to use on multiple parts of your build. Sealants used on external parts of your property will seal the space from drafts, water and insects. Caulk can also be used to support the installation of wood panelling or to fill in holes or cracks in your drywall.
