Pick your units and whether you are buying premix or mixing cement with sand. The bag counts are very different.
How it works
Pieces plus your extra ÷ the typical number each bag lays: 13 block or 37 brick for an 80 lb premix, and 46 block or 144 brick for 70 lb masonry cement with sand.
Before you order
- Premix costs more per wall but saves the sand pile on small jobs.
- Type N suits general above-grade work and Type S handles higher loads, so check what your plans call for.
- Mix only what you can use within your product working time, usually a couple of hours.
