vdw VarioSand Basalt Grey, 25 kg – Jointing sand for narrow paving joints of 2–4 mm
vdw VarioSand in basalt grey is a ready-to-use jointing sand with a hybrid binder for unbound concrete block paving. It is swept in dry, compacted, and then mixed with water to create a slurry. It is suitable for narrow joints of 2 to 4 mm. According to the manufacturer, the finished joint is water-permeable and can be driven on after approximately three days.
Who is vdw VarioSand suitable for?
Areas of application and selection criteria
Typical uses and points to check before processing:
- Concrete block paving with narrow joints
- Private and public areas with normal traffic load
- Joint width consistently 2 to 4 mm
- Joint depth min. 40 mm, full stone height if driven over
- Load-bearing, permanently water-permeable substructure
- Ensure joints are completely dry before sweeping.
- Not suitable for slabs with an edge length exceeding 30 cm.
- Not suitable for high-pressure cleaners or vacuum sweepers
Your advantage when buying
The ready-to-use sand is swept in dry without mixing and is walkable after 3 hours; for wider joints from 5 mm on trafficked areas there is the 2K paving joint mortar vdw 800 .
What you should pay attention to when making your selection
The joint width, type of covering and substructure are crucial, as VarioSand is only designed for narrow joints in unbound construction.
Joint width, joint depth and consumption
The manufacturer estimates 1.5–1.7 kg per liter of joint space, and approximately 3–4 kg/m² for concrete block paving and a joint depth of 40 mm.
Weathering and hardening
Process the sand at temperatures between 8 and 30 °C and protect the area from rain for at least 3 hours and from frost for at least 2 days.
Processing and application limits
After sweeping, the area is compacted, thoroughly moistened section by section, and sanded again; prolonged dampness in the joint damages the material, and a test area reveals possible haze on the stone.
