The Difference Between River Sand and Plaster Sand

Why Choosing the Right Sand Matters

Sand is a crucial ingredient in concrete, mortar, and plaster, but not all sand works the same. Two of the most commonly used types are river sand and plaster sand, each designed for specific purposes. Using the wrong type can lead to weak structures, cracks, or poor finishes.

At Hyperbuild Brick and Sand, we supply both sand types, ensuring you always get the right option for your application.

What Is River Sand?

River sand is naturally collected from riverbeds. It is known for its rounded grain shape, smooth texture, and low impurity levels.

Characteristics:

• Smooth, rounded grains

• Washed and clean

• Low clay content

• Medium-to-coarse texture

Best Uses:

• Concrete mixes

• Floor screeds

• Slabs and foundations

• Certain brickmaking applications

Key Benefits:

• Excellent bonding

• Improved concrete workability

• High structural strength

What Is Plaster Sand?

Plaster sand is finely graded sand specifically processed for plastering walls and ceilings.

Characteristics:

• Very fine grains

• Soft, uniform texture

• Free from stones and coarse particles

• Clean and consistent

Best Uses:

• Wall plastering (interior & exterior)

• Ceilings & skimming work

• Decorative finishes

Key Benefits:

• Smooth, polished surface

• Reduced cracking

• Easy to spread and finish
