Predictable performance in a formulation starts with consistent raw materials. When you need to control texture, strengthen a mix, or ensure chemical inertness, the purity and grading of your aggregate are non-negotiable. GS-BW Silica Sand delivers that exact standard, ensuring your final product performs as specified, every time.

Why this product exists

GS-BW Silica Sand is a precisely graded, high-purity silica sand designed as a foundational component for advanced building materials. It ensures chemical stability, prevents unwanted reactions or discolouration, and contributes reliable physical characteristics to the final product. We supply it to provide a consistent, high-specification aggregate for a range of demanding applications where standard sands would compromise performance or finish.

The numbers that matter

• Greater than 99% SiO2 purity: This ensures chemical inertness within your formulation. Low impurity levels, like less than 0.030% Fe2O3, prevent discolouration in light-coloured applications and maintain the long-term stability of the composite material, reducing the risk of premature degradation or performance shifts.
• Precisely graded particle size: A minimum of 95% passes 0.425mm and a minimum of 95% is retained on 0.105mm. This tight distribution, verified by British Standard Sieves, is critical for controlling rheology, achieving consistent film builds in coatings, and delivering predictable texture or slip resistance in broadcast applications. It also minimises segregation within a mix, contributing to a more homogeneous final product.

What it's like to use

Integrate GS-BW Silica Sand into your base product according to the specific formulation guidelines of the manufacturer. Ensure accurate weighing and thorough mixing to achieve a homogeneous blend. Due to its precise grading, it reduces the risk of inconsistent results from batch to batch when correctly incorporated.

Safety consideration: When handling GS-BW Silica Sand, avoid creating or breathing dust. Crystalline silica dust can cause silicosis and is classified as carcinogenic through inhalation. Always use appropriate personal protective equipment, including respiratory protection, and ensure adequate ventilation in work areas.

Where this product excels

• Textured wall coatings and non-slip paints: The controlled particle size ensures a consistent profile and predictable slip resistance, providing a clean finish and reliable safety performance.
• Epoxy flooring broadcast and build coats: Use it to enhance the wear layer, improve traction, and achieve specific film builds, contributing to the durability and functional properties of the floor system.
• Cementitious grouts and adhesives: Its consistent grading and purity provide rheology control and contribute to the final strength of the cured material, crucial for tiling and other construction applications.
• Acoustic infill and sound proofing: The dense mineral fill helps to dampen vibration and reduce sound transmission, making it effective in specific acoustic barrier systems for builders and service contractors.

Choose this when

• When your formulation requires an aggregate with consistent particle size distribution for predictable results.
• When high chemical purity (>99% SiO2) is critical to prevent discolouration or ensure long-term stability of the finished product.
• When you need to control the rheology, enhance the strength, or provide specific texture in coatings, grouts, or adhesives.
• When precise film build, slip resistance, or acoustic dampening properties are required for your application.

Don't use this when

• Not for: direct application as a standalone sealant or adhesive. For general bonding, consider Adheseal Multi-Grip High-Grab Construction Adhesive.
• Not for: use where a standard, ungraded sand or bulk filler would suffice and specific purity or particle size control is not required.
• Not for: use as a movement-joint material. For sealing joints, Adheseal S100 Sanitary Silicone Sealant is a better fit.
• Not for: structural load transfer without engineering verification of the final composite product it forms a part of.
