Buying caulk by eye leaves either a half-used tube drying in the garage or a second trip in the middle of the job.
Turn total seam length, tube coverage, and waste into a tube count and a shopping number.
Anyone sealing windows, doors, or trim and wanting the right number of tubes.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Measure the length you will seal in feet. Do one window and multiply if the openings match.
Use the coverage printed on the tube for a bead of the size you plan.
Add waste for cuts, gaps, and a bead that runs. Ten to 15 percent is common.
Count unopened tubes on hand. Do not count a tube that has already cured.
The App rounds up to whole tubes and subtracts what you already have.
A 120-foot seam at 25 feet a tube with 15 percent waste needs six tubes. One already on hand leaves five to buy.
Use your own source and details. The example is not a record about a real person or organization.
Two tube counts from the same method. Both are examples.
Both cases are examples, not records about a real person. The bars show the same numbers the free App computes.
