Stone carpets are enjoying ever-increasing popularity. Not only the price-performance ratio is consistent, also offers the modern flooring countless advantages. If you also want to lay a stone carpet, you should pay attention in the execution of certain quality standards. Below you will find valuable tips.
What is a stone carpet? Stein The stone carpet consists of many small stones in a certain grain size. Different materials are used.
- Glass (also colored)
- Shell break
- Sodalite die Especially in the case of quartz, the variety is enormous. In addition to colored quartz, there are also various quartz rocks and (semi) gemstones.
- tiger's eye
- hematite (bloodstone)
- aventurine, green
- rose quartz
- Not only very exclusive stone carpets can be used with it. If, for example, you believe in the natural healing properties of different stones, you can adjust your living space accordingly.
- The outstanding stone carpet properties
In addition there are very practical properties for stone carpets. Basically, a stone carpet is very resilient. The hardness of quartz is 7 and thus exceeds that of different tiles. This gives the stone carpet a high abrasion resistance.
Stone carpets in wet rooms
In wet rooms, it is now also very popular because the rough surface, which can be adjusted by a corresponding grain size, also absolute slip resistance is given. Stone carpets permeable to water. For this reason, they are sealed in damp rooms with a pore seal, which nevertheless only minimally alters the surface structure.
Stone Carpets in Kitchens
In kitchens and other spaces where food is processed and prepared, the stone carpet should also be sealed for hygienic reasons. But also not sealed the floor covering is very easy to clean. You can wet the stone carpet or clean it with a steam jet.
Further basic characteristics
Due to its structure, a stone carpet also absorbs sound, which is why it has the greatest possible sound-reducing effect and provides good acoustic insulation. The structure is also well ventilated, so that there is an air cushion in the stone carpet. Therefore, he feels warm when entering (barefoot).
Outdoor Stone Carpets
You can also lay stone carpets outdoors, as they are absolutely frost-proof. In addition, you will never again have problems with ice, since the water runs through the stone carpet. Here we come to the peculiarities that you have to consider when laying stone carpets.
Requirements for the Subfloor
In the outdoor area, the substrate must be prepared so that the water-impermeable layer lies beneath the stone carpet. To do this, you have to work a gradient into the lower layer so that the water can actually run off. In the stone carpet you do not have to consider this gradient.
Operations to lay a stone carpet
When commissioning you recognize quickly. Whether it is a knowledgeable company that actually moves the stone carpet in high quality for you, or just wants to take the largest possible profit. Therefore, first the construction of a stone carpet.
waterproof layer (possibly also under the screed)
primer to reduce the absorbency
- slightly scattered quartz sand for better adhesion
- stone carpet in perfectly matched binder mixture
- various coatings and / or pore closure
- Waterproof layer
- A non-sealed stone carpet is permeable to liquids. Therefore, the stone carpet should never be applied directly to a water-sensitive underlayer (old wood floor) without proper sealing.
The primer is enormously important. Each substrate has different absorbency and would absorb the binder (epoxy resin) to varying degrees. This "sucked off" binder is then no longer available for a long-term homogeneous and stable bond.
Any operation that deals extensively with stone carpets knows that this will increase the adhesion. It's just a real quality feature.
The binder (epoxy resin)
Here are the biggest differences. In general, however, 2-component epoxy resin is used. However, this binder is relatively expensive. So the amount of binder ultimately defines the total price for a stone carpet that you can lay.
Extremely important: the optimum amount of binder
According to the experience of operators who have been relocating the stone carpets for many years, the information provided by DIY stores and some suppliers is very close to the quality limit. Basically, however, the larger the grain size, the lower the binder requirement.
fine grain size: grain size 2 to 4 mm, layer thickness 6 to 8 mm
medium grain size: grain size 4 to 8 mm, layer thickness 8 to 10 mm
- coarse grain size: grain size 8 to 10 mm, layer thickness 10 to 12 mm
- Go with one fine grain of x percent. For the average grain size you calculate one percent less binder, then from the middle to the coarse grain then again one percent.
- Here it can be saved to your detriment
Some suppliers assume a fine grain size of just 6 percent binder content. However, experienced stone carpet publishers already set the ratio at 8 percent, then one percent less, the coarser the grain size.
Marble: up to 10 percent epoxy resin needed
But that's not enough. Explicitly marble is offered in different varieties. But marble also has a relatively high absorbency, which can vary greatly depending on the variety. Starting with highly absorbent marble, you should even consider a binder content of 10 percent with a fine grain size.
Many quartz stones are now colored. Pay attention to a high quality of dyeing, that is to say, to stones that were literally soaked in color and in which the coloring was not just superficial (with open-pored stone carpet material such as marble).
Sealing, Coating, Pore Closure
As a pure pore seal, a transparent acrylic seal is selected, which is suitable for stone carpets. In addition, there are still coatings with a variety of properties such as fluorescence, high abrasion resistance, special flexibility, high gloss, etc.
Shapes and patterns
One reason why stone carpets are so popular is the ability to incorporate even filigree patterns, figures and color samples. You can use stencils for all shapes. These templates act like a placeholder.
Where you would like to have certain patterns, figures or color separations, these stencils are simply glued to the floor with double-sided adhesive tape. An experienced company always has a design company in the background, which manufactures the templates inexpensively according to individual specifications.
Observe the work execution while laying the stone floor. An experienced craftsman moves step by step, has several trowels and also a construction spotlight, with which he checks how smooth or uneven the stone carpet surface is (drop shadow).
Lay out the abstract for the stone carpet
If you heed all the information we have put together for you, and the operation meets your requirements in relation to it, you will enjoy your stone carpet for many decades.
