Caulk Sink planning guide
Use this quick guide with your rough sink caulk estimate to think through sink type, caulk length, old caulk removal, surface condition, kitchen or bathroom moisture, and whether the seam is hiding a leak or loose sink.
What affects this estimate
- Number of sinks and caulk length around each sink
- Kitchen, bathroom, or utility sink context
- Old caulk removal, residue, staining, mold, or surface damage
- Kitchen/bath silicone, acrylic latex, or mildew-resistant caulk choice
Basic materials/tools
Materials
- • Kitchen/bath caulk or mildew-resistant caulk
- • Caulk remover, scraper, utility blade, painter tape, cleaner, gloves, and towels
- • Caulk gun and smoothing tool if not already owned
Tools
- • Caulk gun, utility knife, scraper, and smoothing tool
- • Painter tape and cleaner for a clean sink edge
- • Gloves and towels for water and residue cleanup
Before you start
- 1Confirm the sink is secure and the seam is dry before estimating this as a caulk-only job.
- 2Remove loose caulk and clean residue so the new bead can bond to the sink and countertop.
- 3Stop if moisture appears to be from plumbing, a loose sink, or a rotten countertop rather than a failed caulk line.
Watch out for
- Using new caulk to hide an active leak under the sink or around the faucet.
- Caulking over damp residue, mold, or old loose caulk.
- Ignoring a loose sink edge or water-damaged countertop material.
