Kiln-dried quartz sand 25kg in 6 grain sizes

Kiln-dried quartz sand 25 kg – for epoxy floor coatings, fillers & mortar

Kiln-dried quartz sand is an indispensable additive for synthetic resin flooring systems. The drying process renders the sand virtually moisture-free – a fundamental requirement for processing with epoxy and polyurethane resins, as moisture would interfere with the curing process.

Depending on the grain size, the quartz sand is used as a filler for scratch coats, leveling compounds, and self-leveling coatings, as broadcasting sand for non-slip surfaces, or as an aggregate for epoxy resin mortars and screeds.

Scope of delivery: 25 kg bag in the selected grain size.

Available grain sizes & typical applications

• 0.06–0.2 mm: fine filler for scratch coats and leveling, e.g., with Sikafloor-2510 W or Sikafloor-1590
• 0.1–0.4 mm: filler for leveling, self-leveling, and mortar coatings (Sikafloor-150 Plus, -151, -264 Plus)
• 0.4–0.8 mm: broadcasting sand for slip-resistant surfaces and broadcast coatings
• 0.7–1.2 mm and 0.8–1.2 mm: coarse broadcasting sand for highly slip-resistant floorings and as a component of screed mixtures
• Mixed sand 0.06–1.2 mm: graded sand mixture, e.g., for epoxy resin repair mortar

Advantages

• Kiln-dried – suitable for epoxy and PU resins
• Six grain sizes for all work stages
• Uniform grain distribution
• Practical 25 kg bag

Typical mixing ratios (according to Sika data sheets)

• Leveling with Sikafloor-151: 1 part resin + 0.5–1 part quartz sand 0.1–0.3 mm
• Mortar coating with Sikafloor-264 Plus: 1 part resin + 0.7 parts quartz sand 0.1–0.3 mm
• Broadcasting: quartz sand 0.3–0.9 mm in excess, approx. 4–6 kg/m²
• Epoxy mortar with Sikafloor-150 Plus: 1 part resin + 10 parts sand mixture

The product data sheet of the resin used is always the definitive guide. If you are unsure about the appropriate grain size, we would be happy to advise you at office@bauchemie.at.

Application

As a filler: Add the quartz sand after mixing the resin and hardener and mix homogeneously for at least 2–3 minutes, e.g., in a mixing bucket.

As broadcasting sand: Scatter into the fresh coating lightly at first, then in excess. Once cured, vacuum up the loose sand and seal the surface.

Storage: Store in a dry place and protect from moisture to ensure the sand remains suitable for resin systems.
