A caulking gun helps me apply the sealant evenly and with precision. I recommend investing in one if I’m planning to do multiple projects.
- Smooth the Sealant
After application, I like to smooth the sealant with a wet finger or a tool. This not only looks better but also helps create a stronger bond.
