About Pour and Spread

Pour and Spread helps you buy the right amount of material for common home projects. Running short means a second trip and a cold joint in your concrete; buying far too much leaves pallets of bags in the garage. Our calculators show how they work out each number and which product data they use, so you can check them against the bag in front of you.

Who runs the site

Pour and Spread is a small independent website run by the Pour and Spread editorial team. We are not a manufacturer, retailer, government agency or professional service, and nobody pays us to feature a product or brand. The site launched on Nov 11, 2026.

We do not put names, job titles or credentials on our pages that we cannot back up. Instead, every page shows what it is based on: the formula behind each calculator and a list of the official or reputable sources we checked, with the date we checked them.

How the tools work

Every calculator runs in your browser. Nothing you type is sent to us. Trackers and logs save to your own device (your browser's local storage), so they stay private and disappear if you clear your browser data. There are no accounts.

How the site is paid for

We plan to support the site with advertising in the future. No ads are shown yet.

Some guides contain a small number of clearly marked links to Amazon search results. As an Amazon Associate I earn from qualifying purchases. See our affiliate disclosure.
