Product questions

What does a stone carpet cost?

First and foremost, the area of application determines the pricing. For example, you can have a stone carpet laid indoors for around €80 plus VAT per m². However, the costs depend on many different factors, including

  • the type of binder required
  • from the primer

  • the choice of skirting boards, for example if these are also made of quartz gravel

  • from the labor costs of the professional installer

  • the size of the area to be laid

In outdoor areas, the costs are higher because the substrate is sealed and a special binder is used.

What different types of stone carpet are there?

In most cases,
colorquartz
or
marble gravel
is used for the production of stone carpets. However, there are considerable differences in quality here, for example in the proportion of dust in the material or in the types of marble used.

What grain sizes are available?

Colored quartz is available in the following grain sizes:

  • 1–2 mm

  • 2–3 mm

  • 3–4 mm

Marble gravel is available in the following grain sizes:

  • 1–4 mm

  • 4–8 mm

  • 8–15 mm

Of course, the choice of gravel grain size has an effect on the laying thickness of the gravel floor.

What material thickness is used to lay stone carpet?

The laying thickness of the floor depends on the gravel grain size and the area of application. Normal quartz gravel with a grain size of 2 – 3 mm can be laid indoors with a thickness of 6 mm.

An installation thickness of 8 mm is used outdoors and on stairs indoors due to the load.

Finally, 10 mm of material is applied to external stairs.

Vertical surfaces such as risers, skirting boards and walls are always laid in 6 mm.

How does the grain size affect the costs?

The larger the grain size of the gravel, the higher the installation height of the floor covering. This means that more gravel and additional binder is required per m². The price increases accordingly.

Why is a primer required for stone carpets?

The primer forms the bonding bridge between the building structure and the gravel floor. The material can be applied to almost any substrate, for example tiles, wood, stone, concrete and metal. Different substrates require different preparation steps.

On tiles and metal, for example, a primer is required to give the smooth surface stability during installation.

On porous stone and absorbent screed, the appropriate primer must be used to prevent the binder from being absorbed, which is intended to ensure that the pebbles remain in place.

To coat wooden planks with a gravel floor, the movement of the planks against each other must first be stopped. To do this, the installer first applies a mesh mat to the wooden floor. Once the filler has dried, the gravel floor is applied.

Which binders are suitable for indoor installation?
For interior applications, we recommend Qubo® Epoxy Resin (Qubo® EP for short). The products in this range are two-component binders for laying gravel floors in interior areas in private and commercial environments.
Qubo® EPs offer the necessary durability to provide floors and treads on stairs with a long-lasting gravel coating. The material is transparent and allows the selected gravel colors to shine.
The vertical binder Qubo® PU-WA08 is used for vertical surfaces such as risers and skirting boards.
Warum sollte ein Steinteppich mit einer Porenversiegelung versehen werden?

For reasons of hygiene, the stone carpet should be fitted with a pore seal, especially in kitchens and
bathrooms
. It prevents leaked, sticky liquids from penetrating the stone carpet. While it is difficult to remove liquids that have penetrated an open floor, the pore seal enables
effortless cleaning
by wet mopping.

Is a stone carpet suitable for pets?

Dogs, cats and co. feel much more comfortable on the textured surface than on smooth floor coverings such as tiles or laminate, as they do not slip on stone carpets. However, it is advisable to cover the floor with a pore seal to ensure an easily wipeable surface.

Can a stone carpet be laid outdoors?
A stone carpet on your
terrace
is the durable alternative to other floor coverings. The system forms a non-slip floor that is 100% frost-proof and UV-resistant
What are the advantages of a stone carpet in outdoor areas?
  • High drainage capacity due to open-pored structure

  • Quick drying in sun and wind

  • Easy to clean and self-cleaning

  • 100% frostsicher

  • UV-stabil

  • Gentle, massage-like walking comfort when walking barefoot
How is the stone carpet laid outdoors?

The most important thing when laying gravel floors in outdoor areas is preparing the substrate. This ensures the durability of the finished floor.

On the one hand, this is because a primed subfloor provides significantly increased adhesion for the filled gravel. On the other hand, a sealing layer keeps rainwater away from the building structure, for example, which supports long-term durability.

Options for sealing building structures are

  • Sealing using a resin seal with a sealing membrane
  • Sealing using a flex sealing slurry

In order to drain rainwater effectively, the floor covering is laid with a gradient of at least 1.5%.

Which binders are suitable for outdoor installation?
For outdoor areas, we recommend Qubo® PU08. This binder is a one-component polyurethane (1C PU) for laying stone carpets on balconies, terraces, pool surrounds and outdoor steps.
Laying with polyurethane as a binder gives the gravel floor the high elasticity required for large temperature differences.
Qubo® PU08 is also absolutely UV-resistant and frost-proof.
Should a pore seal be applied to an outdoor stone carpet?

In outdoor areas, the stone carpet is always laid as an open system to ensure drainage capacity and thus the run-off of rainwater. This makes them 100% frost-proof and therefore ideal as
pool surrounds
and as a covering for balconies, terraces, entrance areas, outdoor steps and loggias.

How do you clean a stone carpet indoors and outdoors?
Indoors, the gravel floor can simply be vacuumed or damp mopped. Heavier soiling can be removed with a wet vacuum cleaner or steam cleaner.
The exterior can be cleaned using a high-pressure cleaner with a brush system. Without a brush system, the dirt is pressed between the pebbles. This reduces the drainage capacity and makes it even more difficult to remove the dirt.
Further information on the subject of cleaning can be found in our
section worth knowing
.
Can a stone carpet be mended or repaired?
Defects can be seamlessly repaired after structural changes such as moving a wall. However, it must be remembered that color changes due to environmental influences and the natural aging process cannot be ruled out.
Is a stone carpet waterproof?
The waterproofing of the building structure is the water-bearing layer. To make the interior stone carpet waterproof, we use a pore seal in combination with an epoxy resin sealant. Qubo® EP (glossy) can be used as an epoxy resin sealant.
Another option is a semi-matt or anti-slip polyurethane sealant.

We would like to point out that we do not recommend stone carpets in the direct shower area. The reasons for this can be found in the basic structure of the floor and the wet room. Just as the tile adhesive under a tile does not form a completely flat surface without air pockets, pores also remain underneath a sealed stone carpet.

If, after years, a silicone seam leaks and water from a fitting, for example, penetrates between the wall or floor covering and the seal of the building structure, the transparent pore seal reacts with the water and forms white stains. As these occur underneath the seal, they cannot be wiped away or removed by drying.

This is why insurance companies do not classify stone carpets as suitable for wet rooms and do not replace such coatings in the event of damage. We therefore recommend microcement coatings for showers. With these, there is no water-bearing layer between the floor covering and the substrate, so there is no risk of moisture penetration. Due to the many customization options for microcement, it can also be combined with stone carpeting. Just get in touch with us.

Can a stone carpet be laid on stairs?
With marble and quartz gravel, old
stairs
can be easily renovated both indoors and outdoors. Coating your old staircase with stone carpet gives you a new design without having to invest in a new staircase. Renovation is carried out without any chiselling or demolition work. Staircase renovation significantly reduces or even completely eliminates noise. Of course, stone carpeting is also ideal for new staircases and entrance areas.
Can stairs be renovated with non-slip stone carpet?

A staircase coated with stone carpet already has a slip resistance class of R10 after installation.

The slip resistance class can be increased to R11 or R12 using special sealants.

How long does a staircase renovation with stone carpeting take?

Depending on the type of staircase, renovations are possible within 3-5 days.
Please contact us to discuss the details

What is a natural stone carpet?

All our gravel floors use natural stones as the base material. This is why many people also refer to stone carpeting as
natural stone carpeting
.

The gravel is available natural and colored.

How long does a stone carpet last?

A professionally laid floor can practically only be destroyed by chemical stress or under the influence of enormous mechanical forces. It can therefore be assumed that a well-maintained floor will last for several decades.

How do I remove a stone carpet?

A separating layer can be worked into the floor coating during installation. This additional step during installation makes it very easy and effortless to remove the gravel flooring.

Can gemstones be incorporated into a stone carpet?

Mica additives and various gemstones can be added, but this represents a further cost factor.

In addition to the uncolored natural quartz, quartz gravel is also available in various colors. The quartz gravel can be ordered in single-colored, double-colored or metallic versions.

Are there any other positive properties of Qubo® quartz gravel flooring?

Our Qubo® quartz gravel floors are naturally solvent-free. They are characterized by a pleasant walking comfort, which is created by the stone structure.

The textured surface also makes the floor anti-allergenic. This means that the fine house dust settles in the individual pores, is not trapped and can simply be vacuumed out. This floor is therefore predestined for house dust allergy sufferers, making it ideal for laying in bedrooms. Of course, it can also be wet mopped. A wet vacuum cleaner is suitable for basic cleaning.

The sealing with a pore seal ensures a hygienic surface. The quartz floor is also very warm underfoot. This effect is created by the insulating effect of the many small air chambers in the floor system.

Depending on the design of the staircase, the renovation takes 3-5 days.

Is a quartz gravel floor suitable for underfloor heating?

Due to its structure and thin layer thickness, a quartz gravel floor is ideal for underfloor heating.

The quartz gravel layer, which is only a few millimetres thick, heats up faster than a much thicker tiled floor, for example. At the same time, the granular structure of the quartz gravel floor provides a considerably larger surface area than smooth floor coverings. This allows the heat to be transferred to the room air more quickly.

Can quartz gravel flooring be laid on stairs?

Due to its insensitivity to dirt, it is very suitable for laying on stairs. This also applies to corridors, foyers and entrance areas.

How is an epoxy resin floor constructed?

Our Qubo® Resin epoxy resin flooring generally consists of at least two layers. The bottom layer is the same for all types of construction and consists of a primer in the desired floor color, which evens out any unevenness. The actual design layer is applied to this now even base.

With colored epoxy flooring, this is the pigmented epoxy resin. In addition to the desired color, the design layer can be enhanced with special pigments and effects. A pigmented epoxy resin floor with a glossy surface is already laid at this point.

To give the surface a matt look or a silky matt finish, a suitable sealant can be applied at the end.

With the 3D floor, the photo film is fixed after priming. The final top layer is then poured using the transparent resin.

When can an epoxy resin floor be walked on?

Each of the applied layers can be walked on after a curing time of 24 hours. Depending on the existing substrate, additional preparation steps may be necessary so that the finished floor can be walked on after 3-4 days. The epoxy resin is fully cured and can withstand maximum loads after 7 days.
