Frequently Asked Questions
Why does dried silica sand matter when normal sand is cheaper?
Moisture. Epoxy mixes and resin-based fills react badly to wet aggregate, and sweep-in sand needs to be dry to settle into joints. Kiln drying makes the behaviour predictable.
What are the common uses?
Extending epoxy grouts and mortars, joint sand for pavers, and dry-mix screed components where consistent moisture content decides the cure. Match the product spec to the job conditions before you start.
How fine is the dried silica sand graded?
Kiln-dried and graded for consistent blending with cement and resin binders, so grout and epoxy fills cure to even strength without wet or oversize particles weakening the mix.
Does it need storing somewhere special?
Keep the bag sealed and off concrete in a dry space. Dried sand that picks up moisture clumps and throws out water ratios in resin or cement mixes.
Can it be used in epoxy grouts?
Yes. Dried silica is the standard filler for epoxy grouts and polymer repairs because it carries no moisture to upset the cure and blends to a consistent colour.
Is silica sand suitable under pavers?
It suits bedding and joint filling on pedestal and sand-bed paving where a free-draining, non-reactive fill is wanted. Compact lightly so the bed stays even.
