Typical sequence before film finish.
| Stage | Grit | Purpose |
|---|---|---|
| Rough | 80–100 | Remove mill marks |
| Smooth | 120–150 | Even surface |
| Pre-finish | 180–220 | Before stain |
| Between coats | 320–400 | Scuff |
Verify all calculator inputs against physical measurements before cutting or mixing.
Compare results to known good references in woodworking before final assembly.
Pause immediately if tools malfunction, ventilation fails, or materials react unexpectedly.
Crucial code requirements, material risk alerts, and prevention checklists for Wood Finishing Basics.
⚠️ Risk Warning: Purchasing net calculated material causes project delays when cuts or breakage occur.
💡 Prevention Action: Always add a 10%-15% buffer allowance to initial calculated quantities.
⚠️ Risk Warning: Applying finishes to dusty or uneven surfaces reduces adhesion by up to 60%.
💡 Prevention Action: Vacuum, prime, and check levelness (max 1/8" gap over 10 ft) before starting.
