Stone Carpet Complete Set for Outdoor Use

Our complete stone carpet set for outdoor use contains the coordinated materials for installation on horizontal surfaces:

• Primer – for optimal preparation of the substrate
• Quartz sand – for scattering onto the primer or waterproofing
• TECHPUR marble gravel 2–4 mm – in your desired color
• TECHPUR Stone Binder – binder for horizontal surfaces
• Smoothing agent – for a clean and uniform finish of the surface

The required quantity of marble gravel and binder is calculated using our consumption calculator to match your specified area.

Please note: Any necessary waterproofing is not included in the complete set, as this depends on the existing substrate and area of application. A special binder is also required for vertical surfaces.

A stone carpet in outdoor areas can be laid on firm, load-bearing, and appropriately prepared substrates such as concrete, screed, or existing tiles. The substrate must be clean, dry, free of loose particles, and suitable for the intended construction.

Depending on the substrate and area of application, additional preparations or waterproofing may be necessary. Especially for balconies, terraces, and other surfaces exposed to the elements, it is essential to ensure a professional system structure and a sufficient slope for water drainage.

If you are unsure about your existing substrate, we would be happy to advise you on the appropriate structure.

Yes, a stone carpet can also be installed by DIY enthusiasts themselves, provided the necessary preparations are made.

A professionally prepared substrate, the correct mixing ratio of marble gravel and binding agent, a uniform layer thickness, and careful smoothing of the surface are particularly important.

For the most uniform result possible, each area should be processed without long interruptions to avoid visible seams.

With our step-by-step guides as well as the YouTube processing videos, which can be found directly on the product pages of our complete stone carpet sets, the application process is clearly explained and can be followed step by step.

Whether waterproofing is required depends on the existing substrate and the specific area of application.

For balconies, terraces, and other exposed surfaces, we generally recommend a suitable waterproofing layer beneath the stone carpet to protect the substrate from penetrating moisture and potential frost damage.

For a durable outdoor installation, we recommend applying a suitable waterproofing layer after the primer before the stone carpet is laid.

The exact system structure must always be tailored to the existing substrate and the specific structural conditions.

Important: Waterproofing is not included in our complete stone carpet sets, as the required waterproofing system varies depending on the substrate and application area. The appropriate waterproofing can be ordered separately.

For our stone carpet with a grain size of 2–4 mm, we recommend a layer thickness of approx. 8–10 mm.

With a layer thickness of approx. 8 mm, about 25 kg of marble gravel and 2 liters of TECHPUR Stone Binder are required for 2 m².

A uniform layer thickness is important to achieve a homogeneous surface and sufficient stability.

For vertical surfaces such as risers, skirting boards, or wall areas, a special binder for vertical application is required. The TECHPUR Stone Binder included in the complete set is intended exclusively for horizontal surfaces.

For vertical surfaces, the marble gravel is mixed with TECHPUR Stone Binder Vertical and then applied evenly to the appropriately prepared and primed substrate and smoothed out.

You can find the exact material consumption as well as further instructions for the application of vertical surfaces in our step-by-step installation guide.
