Mixing

One batch, fifty minutes

The binder is mixed batch by batch: 1.5 kg for each 25 kg of stone. Each batch must be spread within 45–50 minutes at 23 °C.

Priming

The binder always goes on a primed substrate

The condition of the substrate determines the primer. 2K PRO stone carpet is always applied to a primed substrate.

Dry substrate (max. 5% moisture)

VIRANIX 2K PRO Stone Carpet PU Primer (for dry substrates)2K PRO PU Primer 150–200 g/m² · the standard case 11.990 Ft-tól

Apply the stone carpet after 2–3 hours and within 4 hours at the latest, while the primer is still slightly tacky.

When you need to work fast

VIRANIX 2K PRO PU Primer Nedves – fast-curing2K PRO PU Primer Nedves (fast-curing) 150–300 g/m² · dry within 1 day at 20 °C 17.990 Ft-tól

For dry or damp substrates; delaying the next layer is not a problem.

If rising ground moisture or dampness is suspected

VIRANIX VAPOGRIP EP 2K - Vapor-Permeable Epoxy PrimerVAPOGRIP EP 2K approx. 0.15 kg/m² · water-based epoxy 12.000 Ft-tól

Used instead of the PU primer. Apply the stone carpet once VAPOGRIP EP 2K is ready to be overcoated (approx. 24 hours at 20 °C).

For old tiled or coated surfaces, we recommend the layer build-up based on an individual quote: request a quote.

Applications

Where to use it

A system developed for outdoor surfaces exposed to rain, for both foot and vehicle traffic. For living spaces and walls, we recommend VIRANIX 1K stone carpet.

  • Terrace

    For outdoor terraces exposed to sun and rain, on a stable substrate laid to a fall.

  • Balcony

    On a waterproofed substrate: 2K PRO is water-permeable and does not replace waterproofing.

  • Walkways, garden paths

    For outdoor surfaces exposed to rain, where water needs to drain away.

  • Outdoor stairs

    On stable, load-bearing steps, at least 8 mm thick, with edge protection profiles.

  • Pool surrounds

    Open-pored surface: water drains through it instead of standing on top.

  • Driveway, garage

    Also for vehicle traffic, at least 8 mm thick, after full cure; for outdoor parking spaces and indoor garages.

Application

Mixing and application

Accurate dosing and keeping to the pot life are essential for a durable surface.

  1. Prepare and prime the substrate

    Apply 2K PRO PU Primer to a stable, clean, dry substrate (VAPOGRIP EP 2K with ground moisture). Fix the 8 mm edge protection profile along the edges.

    Tipp Apply the stone carpet to the primer after 2–3 hours and within 4 hours at the latest.

  2. Mix the two components

    Mix components A and B in a 4 : 3 ratio at low speed until uniform.

    Figyelem Only mix as much as you can spread within 45–50 minutes.

  3. Add the stone

    Pour the mixed binder onto the dry stone (25 kg stone + 1.5 kg binder) and mix until every grain is evenly coated.

  4. Spread and compact

    With a stainless steel trowel, at least 8 mm thick, using even pressure.

    Tipp Depending on compaction, the actual thickness may be 10–15% greater.

  5. Let it cure

    Full cure takes 7 days at 23 °C. Protect the surface until then and allow vehicle traffic only afterwards.

How much binder do I need?

1.5 kg for one 25 kg bag of 2–4 or 3–5 mm VIRANIX 2K PRO stone. The 14 kg pack is enough for approx. 9 bags of stone.

What is the mixing ratio?

A : B = 4 : 3. Mix the two components at low speed until uniform, and only then add them to the stone.

How long do I have to apply it?

One batch within 45–50 minutes at 23 °C. Pot life is shorter in warm weather, so only mix as much as you can safely spread.

When can it be used?

Full cure takes 7 days at 23 °C; allow vehicle traffic only after that.

Is a primer needed?

Yes. On dry substrates, use 2K PRO PU Primer; if ground moisture or dampness is suspected, use VAPOGRIP EP 2K.

Can it be used with other stone?

The dosage data apply to VIRANIX 2K PRO stone. With other grain sizes, the required quantity may differ; please ask us for advice.

Where can I find the safety data sheet?

We will send it to you free of charge on request: write to info@viranix.hu.
