Caulking Basics for Small Home Repairs
Good caulking starts with cleaning the surface, choosing the right caulk, cutting a small tip, applying steady pressure, and smoothing the bead before it skins over.
Choose the Right Caulk
Bathrooms and kitchens need products designed for moisture. Paintable trim gaps often need a different type.
Prep Matters
Remove loose old caulk, clean the surface, and let it dry. New caulk over dirty or wet surfaces may fail.
Work Slowly
A smaller bead is easier to control. Smooth it promptly and follow cure times before exposing it to water.
Quick Checklist
- Remove loose old caulk.
- Clean and dry the surface.
- Cut a small nozzle opening.
- Smooth the bead.
- Respect cure time.
FAQ
Can I caulk over old caulk?
Only if the old caulk is clean, sound, and compatible, but removal is often better.
