How to work with mastic sealants
Learning how to use mastic sealants will help you complete any construction project that needs a finishing touch with a flexible seal.
1. Getting started: You want to be sure that any surface you are going to caulk or seal is in place. Have all items you need lined up properly, the caulking area has to be clean.
2. Safety Precautions: Like with all strong adhesives, you want to be safe: wear gloves, use the proper tools, and wash up when finished.
3. Application: Make sure you have the proper caulking gun to apply your mastic sealant. Cut the nozzle as per the manufacturer's instructions and apply to the areas you need to seal. Apply only as much sealant as is necessary to fill the gaps. Wash any spilled sealant away quickly with soap and water before it has a chance to cure.
