Category: Construction

A wall putty order should follow the selected product's consumption and total finished thickness.

Measure the treatment area and enter the product figures. If the required thickness spans several coats, avoid multiplying a total thickness by the coat count again.

## Inputs and controls

* Net surface area. Allowed range: 0.001 to 1000000000
* Area unit: Square feet; Square metres
* Total applied thickness (mm). Allowed range: 0.01 to 50
* Consumption per mm thickness (kg/m²/mm). Allowed range: 0.01 to 20
* Bag mass (kg). Allowed range: 0.01 to 1000
* Ordering allowance (%). Allowed range: 0 to 100. Added once to the measured requirement.
* Bag price (PKR / bag). Allowed range: 0 to 1000000000. Optional. Enter your own supplier quote.

## How to use

* Choose area unit. Enter net surface area.

* Enter total applied thickness, consumption per mm thickness, bag mass, ordering allowance and bag price.

* Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.


## Why use this tool

Product based quantities are more useful than a single bag rule when wall condition and putty systems differ.


## Before relying on the result

Use total finished thickness and consumption from the selected product. Coat count is not applied twice.


## Tool limitations

Use total finished thickness and consumption from the selected product. Coat count is not applied twice.

## Questions

### Do I multiply the finished thickness by every coat?

No. Enter the total finished thickness on the stated consumption basis. Applying coat count again would count the same thickness twice.

### What should I check before using Wall Putty Calculator?

Check Net surface area, Area unit, Total applied thickness and Consumption per mm thickness. Use the exact units shown beside the controls and replace any example values with your own inputs.
