Accurate cost estimation for interior and exterior painting projects with surface preparation Imperial Units
| Putty Type | Coverage (ft²/bag) | Thickness | Best For |
|---|---|---|---|
| Acrylic Putty | 80-120 | 1-2mm | Interior walls |
| Cement-Based | 60-80 | 2-3mm | Exterior walls |
| Ready Mix | 100-140 | 1-1.5mm | Quick repairs |
| Wood Filler | 25-35 lin.ft | - | Trim & doors |
| Epoxy Filler | 40-60 | 3-5mm | Structural repairs |
Note: Coverage assumes standard application with 2mm thickness. Thicker applications require more material.
Preparation Steps:
Formula:
Total Putty Required = (Surface Area × Condition Factor × Coats) ÷ Coverage Rate
Example Calculation:
For a 500 ft² wall with fair condition (40% factor), 2 coats, and 100 ft²/bag coverage:
Putty = (500 × 0.4 × 2) ÷ 100 = 4 bags
Labor Time Estimates:
| Surface Type | Time per 100 ft² |
|---|---|
| Simple Wall | 1-2 hours |
| Textured Ceiling | 2-3 hours |
| Exterior Siding | 3-4 hours |
| Detailed Trim | 4-5 hours |
