Mortar Calculator
Estimate cement, sand, water, bags and material cost for masonry, plaster or screed mortar mixes.
Brick, block, stone veneer and repair mortar.
General brick, block and veneer work where high compressive strength is not the main driver.
Estimate mortar materials
Mortar-calculator intent is a mix takeoff: a known mortar volume, mix strength, waste, cement bags, sand volume and water. The result is for early material planning, not a project mix submittal.
Mix caveats
- Mortar type, masonry unit absorption, weather, sand gradation and additives can change proportions.
- Preblended mortar, masonry cement and Portland-lime mixes should follow the product data sheet.
- Structural masonry and veneer installation details require local code and project specifications.
