When taking on a masonry project, using the right type of sand is key to durability and structural integrity. But what’s the difference between builders sand and mason sand? Understanding the unique properties of each can help you choose the best sand for your needs.
Builders Sand
Builders sand is a general-purpose sand with a medium grain size of up to 1.18mm. It's frequently used under concrete slabs, for mortar in bricklaying, to backfill pipes, and as a base for paving. Builders sand easily compacts and creates solid foundations. The angular grains provide excellent drainage. It's readily available and budget-friendly.
Mason Sand
Mason sand has a slightly finer texture than builders sand, with grains up to 0.75mm. It has fewer impurities that could weaken a mortar mix. Mason sand is blended specifically for use in masonry construction and brick/block laying. Its smoother texture finishes mortar joints nicely. Mason sand costs a bit more than builders sand.
Key Differences
Builders sand is coarser, while mason sand is finer.
Mason sand creates a smoother mortar consistency with better workability.
Builders sand offers better drainage and is more frequently used as a base.
Mason sand better sticks to vertical surfaces when laying brick/block.
Mason sand needs more water added to mortar vs. builders sand.
When selecting which sand to use for mortar, concreting, and construction, consider factors like application, desired texture, cost, and required strength. Both sands have roles in masonry, but mason sand is the higher performing option for bonding brick and block.
