Paint quantity for painters

Calculate the paint for a job from rooms, windows and doors, coats and coverage. The server works out litres and containers, and the AI writes a short summary for the offer.

Result

A table of rooms with area, windows and doors, coats and litres, the litres with reserve, the containers, the material cost and a short summary.

Before an offer, the paint has to be worked out room by room. This tool takes perimeter and height or an area entered directly, deducts windows and doors, multiplies by the coats and divides by the coverage from the data sheet. It adds the reserve and rounds up to whole containers. The AI writes a short summary for the offer and states no figures.

Questions and answers

Who does the calculation?

The server calculates all sums from the table. The AI only writes the text and cannot change the figures.

Where does the coverage come from?

From the product data sheet. The tool contains no coverage values and suggests no product.

How are the litres rounded?

The total is rounded up to 0.01 l and then to whole containers. The rest of the last container is shown.

Is my text stored?

Only as long as needed: 7 days on Free, 30 days with a package – or not at all if you choose not to store it. Processing happens on our own servers in the EU (Poland).

Can I use the result right away?
