Building Sand vs Sharp Sand: Which Should You Use?

The main difference between building sand and sharp sand is their texture and intended use. Building sand is finer and softer, making it better suited to bricklaying mortar and general masonry work. Sharp sand is coarser and grittier, making it more suitable for concrete, floor screeds, paving and other applications where a firmer mix is required.

In simple terms: use building sand for mortar and bricklaying; use sharp sand for concrete, screeding and many paving applications.

What Is Building Sand?

Building sand is a fine, soft sand commonly used for bricklaying and general mortar work. Its finer particles help produce a smooth, workable mortar that can be spread and finished neatly.

Typical uses for building sand include:

• Bricklaying mortar
• Blockwork
• General masonry work
• Pointing, depending on the application
• Mortar mixes where good workability is required

Building sand is generally mixed with cement and water to produce mortar rather than being used on its own.

What Is Sharp Sand?

Sharp sand has a coarser, grittier texture than building sand. Its particles are generally larger and more angular, making it better suited to applications where a stronger, firmer mix or improved drainage is required.

Sharp sand is commonly used for:

• Concrete mixes
• Laying paving and slabs
• Floor screeds
• Landscaping
• Bedding applications
• Some drainage and garden applications

Sharp sand may also be referred to as concreting sand or grit sand, although specifications can vary between products and suppliers.

Building Sand vs Sharp Sand: What's the Difference?

The main difference between building sand and sharp sand is the size and texture of the particles. Building sand is finer and softer, while sharp sand has a noticeably coarser and grittier texture.

Sand characteristics and recommended uses can vary between products, so check the product specification for your particular application.

Can You Use Sharp Sand for Mortar?

Sharp sand can be used in some mortar mixes, but it is not normally the first choice for general bricklaying mortar. Its coarser texture can make the mortar less workable and more difficult to spread and finish neatly.

Building sand is generally preferred for bricklaying because its finer texture produces a smoother, more workable mortar. The correct sand and mix will depend on the application, so always follow the specification for the particular job.

Can You Use Building Sand for Paving Slabs?

Building sand is generally not the preferred choice for bedding paving slabs. Sharp sand is commonly used where a stronger, more stable bedding mix is required because of its coarser texture.

The correct bedding material and mix will depend on the type of paving and installation method, so always follow the paving manufacturer's installation guidance where provided.

Which Sand Do I Need?

For bricklaying and general mortar work, building sand will usually be the appropriate choice.

For concrete, paving, screeding and applications requiring a coarser sand, sharp or concreting sand will generally be more suitable.
