Unlike other units of measurement, this one is a bit complicated.
For other types of civil works, we have some rules which are simple to follow. For painting, we have to calculate the surface area in coefficient method (IS 2015 – 1987)
How to measure the painted area for irregular shapes?
For a better view, please read this post in landscape mode, if you are on the mobile device. 🙂
- No deduction for opening less than 0.5 m2
- No addition to the painting of edges, feeding, molding, jambs, soffits, sills etc.
- Painting work up to 10cm or 4″ (inches) in width or girth shall be measured in RMT (running metres)
This is a collective effort. Do you have any points to share with us? Feel free to contact us in the comment section Let’s learn together 🙂
Painting Area Calculation:
Let’s do a calculation, using the below coefficient.
For Example, If we are going to calculate the painted area of 3′ x 7′ paneled door means,
- If mentioned Overall, only one side of the opening will be taken into the calculation for two sides of painted area.
- If mentioned Each side, two sides will be taken into calculation (for example, 21 sq.ft +21 sq.ft)
|Collapsible / Folding Glass Doors||1.50 (Over all)|
|Corrugated metal doors||1.25 (for each side)|
|Rolling shutters||1.10 (for each side)|
|Open pale fencing and gates, brace and rails||1 (Over all)|
|Corrugated iron sheet||1.14 (for each side)|
|A.C Semi corrugated sheet||1.20 (for each side)|
|Paneled , battened, ledged and braced doors / windows||1.30 (for each side)|
|Flush joinery / doors||1.20 (for each side)|
|Partly paneled / glazed doors||0.80 (for each side)|
|Fully glazed doors||0.80 (for each side)|
|Louvered Joinery||1.80 (for each side)|
|Trellis work fence||2 (Overall)|
|Carved or enriched door||2 (for each side)|
|Weather boarding||1.20 (for each side)|
|Wooden shingle roofing||1.10 (for each side)|
|Match boarding||1.05 (for each side)|
|Plain sheet steel doors||1.10 (for each side)|
|Fully glazed steel doors / windows||0.5 (for each side)|
