Caulks and sealants play an important role in home improvement. Their purpose is to form a bond between different building materials. Air drafts, water, and even pests can enter your home through very small spaces. Using a caulk gun to seal those spaces can help keep out those unwanted elements.
People often use the words “caulk” or “sealant” interchangeably because they function in similar ways. For example, silicone caulk for windows is usually a sealant instead of a true caulk. The biggest difference between caulk and sealant is pliability, or elasticity. The texture of caulk is more rigid than sealants when it is dry. Sealants work better in spaces that expand or contract.
When choosing the right types of caulks and sealants for your projects, you should consider how much pressure there may be on the sealed areas. Clear silicone works well for interior or exterior windows and doors. When an “invisible” or seamless blend to any surface is necessary for your project, choose a clear caulk or sealant. Caulk is typically made from a flexible polymer such as latex or rubber. Waterproof caulk is made from these materials because they block out water and can expand with temperature changes.
Caulk usually doesn’t crack, but may subtly separate from the surface if applied incorrectly. Use caulk instead of grout to connect two different materials, like tile and wood. Flexible caulk should also be used on differing planes, like corners or places where surfaces meet perpendicularly or at an angle.
The right caulk or sealant can make the difference between a job well done or costly repairs and upgrades.
