CaulkCraft

CaulkCraft helps you plan a sealant purchase for repeated joints. Enter total length per joint, width, depth, and the number of identical joints. Add cartridge volume, a waste allowance, and the number of tubes in a pack. Enter an optional pack price to see estimated cost in your own currency.

Results show raw rectangular joint volume, volume with waste, whole tubes, and whole packs to buy. Switch between metric length in metres with width and depth in millimetres, or imperial length in feet with width and depth in inches. The app converts both to millilitres before purchase rounding. Load an example, validate inputs, reset the form, and choose a light or dark theme remembered on your device.

CaulkCraft works offline with no account, ads, analytics, tracking, or Internet permission. Measurements, prices, and results stay in memory; only the theme preference is stored locally.

This is a planning estimate based on a rectangular joint cross section. It does not account for backing rod, bead shape, product-specific coverage, or tooling loss beyond the waste percentage you choose. Check the sealant label and site conditions before buying.
