Community Tips

WarningKasa Team

Never apply new caulk over old caulk; the new material won't bond properly and will fail within months. Remove all existing caulk completely using a caulk removal tool or utility knife, then wipe the joint with a damp cloth and let it dry for at least 2 hours before reapplying.

TipKasa Team

Painter's tape applied 1/8 inch away from the joint on both sides creates a professional edge and prevents caulk from spreading onto tile or tub surfaces, which saves cleanup time and produces a cleaner final appearance than freehand application.

Cost InfoKasa Team

GE Silicone II Window & Door Caulk ($4-7) offers excellent water resistance specifically formulated for wet bathroom environments and typically costs $2-3 less per tube than premium brands like Dow Corning 795 ($8-12), making it the best value for DIY bathroom recaulking projects. ---
