How to use the Wall Putty Calculator

Measure the net wall and ceiling surfaces that will receive putty, excluding openings. Enter the number of coats and the consumption stated for one coat at your chosen thickness. If the supplier gives combined consumption for the whole system, enter one coat and that combined value. The result is the required material weight; round up to whole bags when ordering.

Material sizes & reference dimensions

Use these as common planning references only. Actual product sizes, structural dimensions and effective coverage can vary by manufacturer, region, design and specification.

ReferenceCommon size / rangePlanning note
Area100 m² in the exampleExclude untreated surfaces.
Consumption0.6 kg/m² per coat assumedReplace with product-specific consumption.
Coats2 in the exampleEnter the intended application count.

Cost guide

Multiply the result by your current supplier rate per kg. Check packaging and include delivery, installation and accessories separately. The calculator does not include prices or assume a current market rate.

Simple budgeting method

Calculated quantity × current unit rate + labour + transport + taxes + accessories + waste/contingency = preliminary project budget.

Practical accuracy tips

  • Use the product data sheet for the intended substrate and thickness.
  • Do not multiply a total-system consumption figure by the number of coats again.
  • Cracks, repairs and surface levelling can require additional material.

Frequently asked questions

Is consumption the same for every brand?

No. Product, thickness and substrate affect consumption. Use your chosen product’s stated rate.

How do I convert kilograms to bags?

Divide the result by the weight of one bag and round up to a whole bag.
