Range

Two grain types, eight colors

The color and grain of natural stone may vary slightly from batch to batch; photos are for reference only. For larger surfaces, order the full quantity in a single order.

Aggregate

2–4 mm

marble aggregate

Angular grain, uniform surface appearance. Colors: White, Gray, Brown, Yellow, Black, Black-green.

Pebbles

3–5 mm

marble pebbles

Rounded, polished grain, color blend. Colors: KSZ29, KSZ31.

Coverage

2–2,5 m²

one 25 kg pack at 8 mm

Approx. 2.5 m² with 2–4 mm stone, approx. 2 m² with 3–5 mm stone. Depending on compaction, the actual thickness may be 10–15% greater.

System

Layer build-up and mix

2K PRO stone carpet consists of three components: primer, stone and a two-component PU binder. The stone and binder are mixed together on site.

Water-permeable surface: it lets water through, so it does not replace waterproofing. On balconies and on terraces above living space, waterproofing is required underneath.

Priming

Which primer do you need?

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

Application step by step

The result depends on substrate preparation and accurate dosing.

  1. Prepare the substrate

    The substrate must be stable, load-bearing, clean, dry and free of dust and grease. Repair any spalling first, then fix the 8 mm edge protection and closing profile along the edges.

    Tipp Above approx. 25 m², divide the surface with DILITAPE expansion joints.

  2. Prime

    On dry substrates, apply 2K PRO PU Primer with a roller at 150–200 g/m², without puddles. If ground moisture or dampness is suspected, use VAPOGRIP EP 2K instead.

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

  3. Mix batch by batch

    Mix components A and B of the binder in a 4 : 3 ratio, then pour onto the dry stone (25 kg stone + 1.5 kg binder) and mix at low speed until every grain is coated.

    Figyelem Only prepare as much as you can spread within 45–50 minutes (23 °C).

  4. Spread and compact

    Spread and compact with a stainless steel trowel, using even pressure, to a thickness of at least 8 mm.

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

  5. Let it cure

    Full cure takes 7 days at 23 °C; until then, protect the surface from dust and rain. Allow vehicle traffic only after full cure.

Important

The stone on its own is not a hazardous mixture. Dust may be generated when pouring and mixing: a dust mask, gloves and safety goggles are recommended. You will find the safety instructions for the binder on the binder page.

2K PRO is a water-permeable surface and does not replace waterproofing.

FAQ

Frequently asked questions

Can't find your answer? Call us at +36 70 575 5500 or write to info@viranix.hu.

Does it contain binder?

No. The stone is supplied without binder: order 1.5 kg of VIRANIX 2K PRO PU Binder for every 25 kg pack.

How much do I need?

For an 8 mm layer, one 25 kg pack covers approx. 2.5 m² with 2–4 mm stone and approx. 2 m² with 3–5 mm stone. Allow extra for surfaces with many sections. The 2K PRO calculator works out the complete system.

What is the difference between the two grain types?

The 2–4 mm marble aggregate is angular, gives a uniform surface appearance and comes in six colors. The 3–5 mm KSZ29 and KSZ31 are color blends of rounded, polished marble pebbles.

Is 2K PRO stone carpet waterproof?

No. It is an open-pored, water-permeable surface: it lets water through, so it does not replace waterproofing. On balconies and on terraces above living space, waterproofing is required underneath.

Can cars drive on it?

Yes, at a thickness of at least 8 mm, on a suitable substrate, after full cure (7 days at 23 °C).

Is a topcoat needed?

It is optional. The 2K PRO binder is an aliphatic polyurethane; the surface can be used for foot and vehicle traffic without a topcoat.

Can it be used indoors?

Yes, for indoor garages. For living spaces and walls, we recommend VIRANIX 1K stone carpet; 2K PRO is designed for outdoor surfaces exposed to rain.

Can it be applied over old tiles?

We advise on this based on an individual quote. Tell us about the condition of the surface and we will help you with the layer build-up: request a quote.

Will the color look exactly like the photo?

The color and grain of natural stone may vary slightly from batch to batch; photos are for reference only. For larger surfaces, order the full quantity in a single order.
