Total linear feet = 10 x 12 = 120 ft. Volume = (0.25 x 0.25 x 120 x 12) / 1.805 = 50 fl oz. Tubes needed = 50 / 10.3 = 5 tubes. Cost = 5 x $7 = $35
Inputs
Result
Total linear feet = 15 + 20 = 35 ft. Volume = (0.375 x 0.375 x 12 x 35) / 1.805 = 32.7 fl oz. Tubes needed = ceil(32.7 / 10.3) = 4 tubes. Cost = 4 x $7 = $28
Inputs
Result
Total linear feet = 150 ft. Volume = (0.5 x 0.5 x 12 x 150) / 1.805 = 249.3 fl oz. Tubes needed = ceil(249.3 / 10.3) = 25 tubes. Cost = 25 x $8 = $200
A standard 10.3 oz tube of caulk covers approximately 56 linear feet with a 1/4" bead, 28 feet with a 3/8" bead, or 18 feet with a 1/2" bead. Coverage depends on joint width and depth.
| Bead Size | Linear Ft / Tube | Best For |
|---|---|---|
| 1/4" × 1/4" | ~56 ft | Interior trim, baseboards |
| 3/8" × 3/8" | ~28 ft | Windows, doors, moderate gaps |
| 1/2" × 1/2" | ~18 ft | Exterior joints, large gaps |
Use 1/4" beads for most interior trim and baseboards, 3/8" for windows and doors, and 1/2" for larger gaps or exterior joints. The joint should be slightly overfilled then tooled smooth.
100% silicone caulk is best for bathrooms due to superior water resistance and mold/mildew resistance. It lasts 20+ years but is not paintable. Use kitchen/bath specific formulas with antimicrobial additives.
| Caulk Type | Lifespan | Paintable | Best Use |
|---|---|---|---|
| 100% Silicone | 20+ years | No | Bathrooms, kitchens, windows |
| Latex/Acrylic | 5–10 years | Yes | Interior trim, baseboards |
| Polyurethane | 15–20 years | Yes (3–10 day cure) | Exterior, high-movement joints |
| Butyl Rubber | 10–15 years | No | Roofing, gutters, metal-to-metal |
Measure the perimeter of each window where caulk will be applied (typically around the frame). A standard window averages 12 linear feet of caulking. Multiply number of windows by 12 feet for a quick estimate.
Latex/acrylic and paintable silicone caulks can be painted after curing (1-24 hours). Standard 100% silicone caulk is not paintable. Polyurethane caulk is paintable after 3-10 days. Always check the product label.
Latex/acrylic caulk dries in 1-2 hours and cures in 24 hours. Silicone caulk skins over in 1 hour and fully cures in 24 hours. Polyurethane takes 3-10 days to fully cure. Avoid water exposure during curing.
