Good finishing shows in light, shadow and every detail
Interior Skim Coat Calculator
Estimate the indicative cost of skim coating walls and ceilings, including surface preparation, priming, Q1-Q4 finish level and material class.
This calculator is for those who want to understand the cost of a truly even, refined base for further finishing works.
A perfect wall does not start with paint. It starts with the substrate.

Estimate Skim Coat Scope
Enter rooms, wall height and scope. The calculator will estimate the billable surface area and the net and gross cost.
Treat the result as a reference point before a conversation and an individual quote.
Wall and ceiling surface area
- Walls - floor area and room height are converted into an indicative wall surface area.
- Surface adjustment - the calculator applies a simplified adjustment for typical openings, recesses and room layout.
- Ceilings - you can leave them outside the scope or add them as a separate work item.
Pricing elements
- Substrate preparation - no preparation, developer standard, washing and minor repairs, or comprehensive preparation.
- Priming - a separate cost for surfaces that require stabilisation before skim coating.
- Q1-Q4 finish level - from basic levelling to a more demanding finish for light-sensitive surfaces and high-quality painting.
- Material class - your own material or Comfort, Prestige or Luxury class materials.
How to read the result
- Gross and net cost - the result shows the full indicative value and a breakdown of the key items.
- Price per m² - the average rate makes it easier to compare simple levelling with a higher finishing standard.
- Indicative estimate - the final cost depends on unevenness, cracks, substrate type, corners and the amount of sanding.
