About this calculator

Use the Plaster Coverage to get 2 linked results (Plaster at 2 mm, Plaster at 10 mm) from a single number. It is built for home & construction jobs where a quick, repeatable answer beats guesswork. Plaster thickness depends on how flat the wall is; measure low spots before buying.

How it works

The calculator multiplies your input by a fixed coefficient for each line. For example, every 1 m2 gives 2 kg for plaster at 2 mm.

Worked example

If you enter 30 (Wall area (m2)), Plaster at 2 mm comes to 60 kg and Plaster at 10 mm comes to 300 kg.

Common mistakes

• Plaster thickness depends on how flat the wall is; measure low spots before buying.
• Skipping the check against local building code or manufacturer data.

FAQ

How much plaster at 2 mm do I need per m2?

Each 1 m2 gives 2 kg.

How is Plaster at 10 mm calculated?

Plaster at 10 mm equals your input times 10 kg. With 30 entered, that is 300 kg.

Are the results exact?

Results are precise sums of the stored coefficients, but real-world plaster at 2 mm varies, so keep a safety margin. This is general information, not professional advice.

What is the most common mistake?

Plaster thickness depends on how flat the wall is; measure low spots before buying.
