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.
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.
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.
This sand meets strict physical and chemical specifications, ensuring consistent performance. With over 99% SiO2 purity and controlled particle sizing (Min 95% passing 0.425mm, Min 95% retained 0.105mm), it provides reliability for critical uses like water filtration or glass manufacture.
This product is classified as hazardous, particularly when processed in ways that generate respirable dust. It contains crystalline silica, which may cause silicosis or cancer through prolonged or repeated inhalation. Always implement dust control measures and wear appropriate personal protective equipment.
While it can function as an inert filler in concrete or other mixes, its precise specifications are usually for applications requiring specific performance. For general use, ensure dust control is maintained. Its high purity and controlled particle size are often overkill for basic aggregate needs.
Avoid creating or breathing in dust. Work in well-ventilated areas, ideally with mechanical extraction. Wear dust-proof goggles, PVC or rubber gloves, and a Class P1 or P2 particulate respirator to minimise exposure to respirable crystalline silica.
| Application | Key benefit | Primary trades |
|---|---|---|
| Water Filtration | Consistent particle size (Min 95% passing 0.425mm) for effective and reliable water treatment. | Water treatment specialists, civil contractors |
| Glass Manufacture | High purity (>99% SiO2) minimises impurities, crucial for optical clarity and material integrity. | Glass manufacturers |
| Foundry Casting | Specific particle distribution ensures mold stability and predictable casting results. | Foundry operators |
| Concrete, Adhesives & Grouts | Inert filler with controlled particle size provides consistent mix performance and strength. | Concreters, tilers, adhesive manufacturers |
| Sports Surfaces & Traction Aid | Uniform grading offers specific drainage and surface stability for sporting fields or anti-slip applications. | Landscapers, sports facility builders |
| Textured & Render Finishes | Controlled particle size contributes to specific surface profiles and finish textures. | Renderers, plasterers |
| Epoxy Flooring | Provides defined aggregate for specific texture, strength, and slip resistance in resin systems. | Epoxy flooring installers |
Keep bags sealed and dry. Handle gently to minimise dust. Use local extraction or wet methods where practical.
Distribute evenly into wet coating; allow to gel/cure, then de-dust and overcoat as per the resin system.
Introduce slowly into resin or grout while mixing to avoid clumping. Verify target viscosity and flow before placement.
Signal word: WARNING
Wear dust-proof goggles. Wear PVC, rubber, or cotton gloves. For heavy contamination or large quantities, use coveralls. Where an inhalation risk exists, wear a Class P1 or P2 (Particulate) respirator.
Avoid inhalation. Use in well-ventilated areas. Where an inhalation risk exists, mechanical extraction ventilation is recommended. Wet the product where possible to minimise dust generation. Maintain dust levels below the recommended exposure standard (0.05 mg/m³ TWA for respirable quartz dust).
Eye wash facilities and a safety shower should be available.
Store in a cool, dry, well-ventilated area, away from incompatible substances and foodstuffs. When disposing, ensure the product is covered with moist soil to prevent dust generation and dispose of to an approved Council landfill.
For foundry moulding, ensure all patterns and mould boxes are clean, dry, and free from oil or residual release agents. For epoxy floor systems, concrete surfaces must be sound and cured (28 days minimum), with laitance and contaminants mechanically removed. Vacuum clean immediately prior to resin priming or broadcast.
Apply Adheseal Epoxy Primer System to prepared concrete, then broadcast F6 sand evenly onto wet primer or base coat to create a mechanical key. No primer is needed in metal or sand mould foundry work where F6 acts as the primary mould aggregate.
Adheseal Epoxy Primer SystemEnsure all substrates are clean, dry, and free of oil, dust or efflorescence. On cementitious surfaces, remove loose particles by light grinding or brushing. Verify moisture content is below 75 % RH before mixing into epoxy or cementitious systems.
Use Adheseal Primer 2001 on low-porosity concrete and masonry before applying grouts or adhesives containing F8. For architectural texture coatings, primer may not be required if sand is pre-blended into a compatible binder system.
Adheseal Primer 2001When using custom mixes of F6 and F8, store in sealed dry conditions to avoid moisture absorption. Blend mechanically using a low-speed mixer to ensure even particle distribution before adding binders or resins.
Confirm compatibility with the manufacturer’s binder or resin before final application. For high-adhesion systems, pair with Adheseal Primer 50A for superior wetting and bond stability.
