Mortar Quantity
Mortar for Bedding, Pointing, Repointing & Rendering
Rules of thumb to estimate mortar quantity for bedding, repointing and rendering as follows.
Repointing Bricks, Blocks & Stone Masonry
10kg mortar will repoint 1 square metre of brickwork with joints 10mm wide x 20mm deep.
10kg mortar will repoint 17 linear metres with one continuous joint 10mm wide x 20mm deep.
Bedding & Laying Bricks, Blocks & Stone Masonry
10kg mortar will lay 10 bricks with a 10mm joint (where brick size: 230mm x 100mm x 10mm).
20kg mortar will lay 10 blocks with a 10mm joint (where block size: 460mm x 100mm x 10mm).
Rendering
15kg mortar will cover 1 square metre of render at 10mm thick.
Please Note
These quantities are approximate, don't forget to allow for wastage, typically waste 5%, allow more for render.
