Clay is a finely milled, air-separated material used as a plasticiser in mortar and render applications. It is especially useful when sands are low in clay content, improving workability and cohesion for masonry and concrete mixes.

This versatile product can also be used as a general purpose filler for construction and landscaping projects, making it a practical choice for DIY enthusiasts, professional builders and landscapers.

Clay is commonly used for:

  • Improving workability of mortars and renders
  • Blending with sand and cement for masonry applications
  • Filling gaps or voids in construction and landscaping
  • Garden and outdoor feature installations
  • General purpose filler for DIY and professional projects


Product Benefits

The Yard Pro Tip
For optimal results, blend Clay gradually into your mortar or render mix until a smooth, consistent texture is achieved. This will improve adhesion, plasticity and overall workability, especially for landscaping or masonry features.
