How to use
- Set units and container size.
- Enter area, coverage, coats, and dilution for each process.
- Check required quantities and adjust loss if needed.
Assumptions
- Per process: area A, coverage C (area per volume), coats N, dilution D.
- Dilution D is thinner added to paint. Example: 10% → 0.1 thinner per 1 paint.
- If coverage is pre-dilution: pre = (A/C)×N, post = pre×(1+d).
- If coverage is post-dilution: post = (A/C)×N, pre = post/(1+d).
- If loss W is set: multiply pre/post by (1+w).
- Can count is calculated by rounding up the pre-dilution total to container size.
Nontice
- This result is an estimate. Required quantities vary with substrate condition, temperature, absorption, application method, and losses. Follow site conditions and manufacturer specifications.
- This tool is a calculation aid and not a substitute for design, regulations, contracts, or safety requirements.
- Preset values are examples and will vary by conditions.
