Check your inputs

Spread rate depends on substrate condition and adhesive application method (ribbon-and-dab vs. full coverage) — confirm your specific adhesive product's technical data sheet.

With the figures above, the adhesive needed comes to 300 kg. The method behind this is well established, though site conditions and material batches will move it somewhat. This is calculated for United States and cites IRC 2024. Building in another market? Change the selector above so the units and code reference follow.

Estimated cost — your price

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

Why does adhesive need vary so much between products?
Spread rate depends on the substrate condition and the application method — a full-coverage notched-trowel application uses more adhesive per square meter than a ribbon-and-dab method, so always use your specific product's rated spread rate.
Where do I find the spread rate for my adhesive?
The adhesive manufacturer's technical data sheet lists the rated coverage rate (kg per m²) for the application method you're using — use that figure rather than a generic assumption.
Does this include adhesive for the base coat or mesh embedding?
No — this calculates only the adhesive used to attach the foam board to the substrate. Base coat and mesh embedding materials are estimated separately.
