How to use it
- Pick bricks or blocks
Type the size, or tap the usual one of your country.
- Type the wall
Its length and height, the area of any openings and the joint.
- Set the cement bag
Type your bag size. Cement and sand are for a 1 to 4 mortar.
Tips
- Breakage
5% extra covers broken and cut bricks on a plain wall. Add more for many corners.
- Joints
A 10 mm or 3/8 in joint is usual. A thicker joint takes fewer bricks and more mortar.
- Openings
Type the area of the windows and doors: a 1.2 × 1.2 m window is 1.44 m².
