Frequently Asked Questions

How accurate is the plaster calculator?

Our calculator is over 95% accurate when measurements are entered correctly. The built-in waste factor helps account for normal job site conditions.

Do I need to subtract windows and doors?

Yes. Measure doors and windows separately and subtract their area from your total wall area for the most accurate results.

What thickness should I use for my plaster?

For most walls, 1/2 inch total thickness works well. Use 3/8 inch for patch jobs and up to 3/4 inch for uneven surfaces. The calculator has preset options for each job type.

Can I use the calculator for outdoor plastering?

Yes! Just select “exterior” in the options menu. The calculator will adjust for weather factors and suggest suitable plaster types.

How much extra should I buy?

The calculator includes a 10% waste factor. For beginners, you might want to add another 5%. For pros, the built-in 10% is usually enough.

Does the calculator work for all plaster brands?

Yes. You can select from major brands or enter custom bag sizes for any product you use.

Can I save my calculations?

Yes, create a free account to save projects. This helps when you need to buy more supplies or work on similar projects later.

What if I’m plastering an irregular shape?

Break the area into simple shapes (rectangles, triangles), calculate each separately, then add them together. Or use the “irregular shape” tool in the app.

How do I calculate for textured finish?

Select “textured” in the finish type menu. The calculator will add the right amount of extra material based on the texture depth you choose.

Will the calculator tell me how many bags to buy?
