Description  

Sunstate Dried Silica Sand is a processed, graded quartz aggregate for resin flooring, sand-broadcast finishes and compatible cementitious or epoxy mortars. The sand is dried and separated into different grades so installers can select the particle size needed for the finish, surface texture or mix design.

Choose the grade to match the flooring or mortar system, rather than treating every silica sand as interchangeable. The listed options include F8 Blended (0.4–1mm), F6 and F4. These are separate grading selections; check the product variant and relevant system specification before ordering.

Where graded dried sand is used

  • Epoxy floor broadcast: adding a specified aggregate to wet resin for texture and subsequent overcoating.
  • Epoxy repair and coving mortars: blending compatible graded silica into resin binder to achieve the required mortar consistency.
  • Cementitious repair and floor toppings: adding sand of the approved grade where a mortar formulation calls for it.
  • Specialist aggregate blends: selecting consistent dried grading for documented construction applications.

Before you choose a grade

Different grades change the workability, texture and consumption of the finished system. Follow the resin, coating or mortar supplier's instructions for grade, loading, preparation and application. A fine glass-grade silica specification must not be assumed to describe the F8, F6 and F4 bags.

Silica dust can be hazardous if inhaled. Minimise airborne dust and use the dust controls, ventilation and respiratory protection required by the applicable SDS and workplace procedures. Do not specify this product for pool filtration, blasting or food-contact applications without grade-specific approval.

Common Questions  

What particle size is the silica sand?
At least 95% passes 0.425mm and at least 95% is retained on 0.105mm.

What silica purity is stated?
More than 99% SiO₂ in the current product evidence.

Can it be used in any epoxy or mortar?
No. Use it only where the host product or system permits this aggregate grading.

Should the sand be kept dry?
Yes. Moisture or contamination can affect the host mix or broadcast system.

Uses & Benefits  
High-purity dried graded silica sand for use as an inert aggregate and filler in compatible trade and industrial mixes. Current product evidence states more than 99% SiO₂. At least 95% of particles pass 0.425mm and at least 95% are retained on 0.105mm. Iron oxide content is below 0.030% in the current product evidence. Consistent grading supports repeatable mix design and broadcast applications.
How To Apply  
Confirm the required aggregate grading and addition rate from the host product instructions. Keep the silica sand dry before use. For resin or mortar mixes, add it at the stage and ratio specified by the system manufacturer and mix until uniformly distributed. For broadcast applications, apply into the wet primer or coating at the rate specified by the complete system. Remove loose excess aggregate after cure before subsequent coats where required.
Limitations and Safety Info  
Use only where the host resin, cementitious product or coating system permits clean dried silica aggregate. Do not substitute this grading where a system specifies a different aggregate size. Keep the sand dry and free from contamination before mixing or broadcasting. Use appropriate respiratory controls for respirable crystalline silica dust in accordance with the current SDS and workplace requirements.
Suitable Substrates  
  • Compatible epoxy and resin flooring or repair systems.
  • Compatible cementitious mortars and grouts requiring graded silica aggregate.
  • Wet primers or coatings that specify a dried silica-sand broadcast.

Sunstate Dried Silica Sand - Use Cases

Here are some common examples on where Sunstate Dried Silica Sand used by our customers.

Caulking

Adjusting Sealant/Adhesive Properties

When customising bulk sealants, adhesives, or coatings for specific viscosity, texture, or added strength requirements.

Consistent grading and high purity ensure reliable property modification without compromising the system's performance or integrity.

  • 95% passing 0.425 mm sieve
  • 95% retained 0.105 mm sieve
  • >99% SiO2 purity
  • <0.030% Fe2O3 content

Masonry

Precision Grout/Mortar Aggregate

Creating specialty grouts or repair mortars that demand extremely consistent particle sizing and inert filler for predictable performance.

Graded particle size and chemical inertness provide reliable strength, controlled flow, and consistent finish for high-specification mixes.

  • 0.105 mm to 0.425 mm graded
  • >99% SiO2 purity
  • <0.0006% Cr2O3 content
  • <0.10% TiO2 content

Civil Construction

Purity for Sensitive Formulations

Mixing filler into moisture-sensitive resins, epoxies, or colour-critical sealants where impurities cause critical defects.

This dried, high-purity aggregate prevents moisture-induced failures, discolouration, and chemical reactions within sensitive systems.

  • >99% SiO2 content
  • <0.030% Fe2O3 content
  • <0.12% Al2O3 content
  • Supplied as dried product

Flooring

Epoxy flooring broadcast aggregate

When creating durable, slip-resistant epoxy floor systems that require controlled texture and wear resistance.

Precisely graded silica provides uniform texture and enhances wear resistance, contributing to a robust and long-lasting finish.

  • >99% SiO2 purity
  • 95% passing 0.425mm
  • Improved wear layer
  • Epoxy build coats

Tiling

Cementitious grouts and adhesives

As a filler to control rheology, improve workability, and enhance strength in cement-based products.

High purity and precise particle size distribution optimize mix consistency and contribute to the final product's mechanical strength.

  • >99% SiO2 purity
  • 95% retained 0.105mm
  • Rheology control
  • Strength contribution
