IS 1200 Part 15 (1987) specifies the standardized method of measurement for painting, polishing, varnishing, and related finishing works in building and civil engineering projects. It provides detailed guidelines on how to quantify these surface treatments accurately, including measurement units, multiplying factors for uneven surfaces, and treatment of various materials like wood, steel, and corrugated sheets. This standard is essential for engineers, contractors, and quantity surveyors involved in estimating, planning, and executing finishing trades in construction and civil engineering works across India.

Frequently Asked
Under IS 1200 Part 15 (1987), uneven surfaces like trellis work and louvred joinery are measured as follows:
| Description | Multiplying Factor |
|---|---|
| Trellis (one-way or two-way) | 2.0 |
| Fully venetianed or louvred joinery | 1.8 |
Loading diagram...
This ensures the complex surface texture is accounted for in painting quantity estimation.
According to IS 1200 Part 15 (1987), Clause 3.6, the multiplying factors for painting on corrugated sheets and patterned roofs are as follows:
| Surface Type | Multiplying Factor (Increase in Area) |
|---|---|
| Corrugated sheets | 14% (multiply flat area by 1.14) |
| Nainital pattern roof (plain sheets with rolls) | 10% (multiply flat area by 1.10) |
| Nainital pattern roof with corrugated sheets | 25% (multiply flat area by 1.25) |
| Asbestos cement sheets, corrugated | 20% (multiply flat area by 1.20) |
| Asbestos cement sheets, semi-corrugated | 10% (multiply flat area by 1.10) |
This adjustment accounts for the increased surface due to corrugation or pattern.
If flat area of corrugated sheet = 100 m²
Equivalent area for painting = 100 × 1.14 = 114 m²
This ensures accurate estimation of paint quantity and cost.
According to IS 1200 Part 15:
Yes, preparatory work such as priming and knotting is included and measured as part of the painting work, but must be itemized and described separately in the measurement.
Loading diagram...
According to IS 1200 Part 15, painting on fabricated steel and iron work is quantified as follows:
Priming coat is included with the fabrication cost.
Subsequent coats are measured separately based on either:
The weight or area of steel components (sheets, plates, rods, tubes, etc.) is taken from relevant Indian Standards.
Rivet heads, bolt heads, nuts (with/without washers), including projecting shanks, if painted in a different tint, are measured as extra items.
No additional weight is added for paint thickness on steel/iron weight.
Surfaces must be described clearly, specifying if measurements are on flat or girthed surfaces.
Uneven surfaces are converted into equivalent plain areas using Table 1 (conversion factors for irregular surfaces).
Painting on different surface types (non-absorbent like steel vs semi-absorbent like wood) is measured separately.
| Paint Coat Type | Measurement Basis |
|---|---|
| Priming coat | Included with fabrication |
| Subsequent coats | Weight or surface area (m²) |
| Special items (nuts, bolts) | Enumerated separately as extras |
This ensures precise and fair quantification of painting work on fabricated steel and iron structures.
According to IS 1200 Part 15:
0.1 m² to ≤ 0.5 m²
0.5 m² to ≤ 1 m²
| Type of Painting | Measurement Method |
|---|---|
| Small articles ≤ 0.1 m² | Enumerated (counted) |
| Repair painting ≤ 1 m² | Enumerated in size categories |
| Large areas | Measured in m², flat or girthed |
| Uneven surfaces | Area × multiplying factor (Table 1) |
This ensures fair and consistent measurement for different painting scopes.
