Just make a stone carpet yourself

The stone carpet is currently one of the most popular floor coverings ever. Among other things, it is also known as a natural stone carpet. Not only that the natural stone carpet offers a whole range of first-class advantages, but also making the stone carpet yourself is very easy. So that nothing really goes wrong, we will then offer you a comprehensive guide to making your own stone carpet.

Benefits and materials for a stone carpet

Stone carpets are probably so popular because it is on the one hand a very natural-looking product and thus creates a very special living atmosphere. On the other hand, you create homogeneous, joint-free surfaces that underline this feeling. The selection of different stones leaves nothing to be desired.

  • marble
  • Quartz (mica, rock crystal / crystal, different colored quartz)
  • alabaster
  • Tigereye
  • Glass (also colored)
  • Bloodstone (a breathtakingly beautiful stone)
  • and many more

Structural stone carpet construction

Most importantly, the individual elements are optimally matched. For a stone carpet you need the following expansion.

  • waterproof (or outside water-draining) underground
  • Primer (to neutralize the wicking behavior)
  • Stone-Binder mixture in the absolutely optimal mixing ratio
  • Sealing (pore closure) in damp rooms and kitchens
  • possibly special coatings (fluorescent, elastic or abrasion-resistant, matt, high-gloss)

The outstanding mixing ratio liquid plastic / stones

The mixing ratio is by far a decisive quality feature in the longevity of your stone carpet. Since the binder (epoxy resin or PU resin) is relatively expensive and the amount of stones required is usually already estimated with the minimum amount, some suppliers "save" the resin requirements more attractive.

The right mixing ratio: do not save at the wrong end!

First, the resin requirement depends on the grain size. You can classify them three times.

fine grain size: 2 to 4 mm
average grain size: 4 to 8 mm
coarse grain size: 8 to 12 mm

Starting with a fine grain size, many suppliers assume demand of 5 percent or more. This is definitely extremely tough on the border. Most providers range between 6 and 7 percent, but few suppliers, who have the relevant practical experience, confirm a need for at least 8 percent binder.

Note the special properties of marble

That there is talk of a "minimum requirement" also has its reasons. Many providers also conceal that the different marble stones have a different suction behavior. If the substrate (therefore the primer) or the marble (therefore the higher proportion of binder) would absorb too much binder, the durable pebble composite would suffer in the long term and more and more pebbles would be released.

Shapes, patterns and color boundaries

Patterns and different color fields can be achieved by delimitation (fields) or templates (figures, filigree patterns). In addition, experienced service providers also offer a template service.

Make step by step instructions for the stone carpet itself

  • primer
  • quartz sand
  • stone mixtures
  • Binder (PU or epoxy resin)
  • possibly sealing, pore closure
  • individual materials (finishing and protection strips, special coatings, etc.)
  • Roller for the primer
  • telescoping rod
  • mortar bucket
  • drilling machine
  • whisk
  • Trowel, long, square on one side, round on the other
  • Trowel, short, square on one side, round on the other
  • Trowel, medium sized, rounded off on both sides (for the final leveling)
  • Construction site washes at ground level
  • Rubber wiper (for the hand, without extension)

1. Preparatory work

Of course you have to clean the ground thoroughly. Best sweep and suck the floor. Then start rolling out the primer.

Attention: some suppliers offer a primer that acts as an adhesive. You have to process this glue in layers, so lay the stones after each freshly rolled web.

2. The priming

For priming, use the same procedure as for painting or rolling a conventional wall. After priming, sprinkle some quartz sand. From the crowd into something you would sprinkle on road salt on a walkway. In addition, sprinkle the sand from the crowd as in salt sprinkling.

3. Mix the binder and the stone carpet

PU resin is a 1-component system, epoxy resin is a 2-component system. Use epoxy resin, mix both components exactly according to the manufacturer's instructions and mix the liquid plastic well. Then add the exactly specified amount of stones and mix the ingredients again extensively.

4. Laying the stone carpet

Now put enough stone carpet on the floor and start distributing. Depending on the grain, you have to form layers of different thicknesses. With fine grain size, for example 6 to 8 mm. For final leveling (smoothing), pick up the construction site light. Flood the strong light directly over the stone carpet surface. Unevenness can be recognized immediately by the pointing drop shadow.

5. Seal the stone carpet

In damp rooms and kitchens you can now apply the seal or pore seal. Distribute the seal according to the manufacturer's instructions with a rubber wiper (without extension).

Tips & Tricks

Stone carpets are ideal for allergy sufferers. They bind dust and pollen. During regular, wet cleaning (wiping or steam cleaning), the dust is then removed immediately. The stone carpet needs 24 hours after installation until it is accessible. After 48 hours you can put your furniture back on it, after a week it is completely hardened. PU resin is more flexible and UV resistant. But even indoors, PU resin prevents a long-term afterglow that can not be avoided with epoxy resin. For this purpose, epoxy resin has a higher strength, which can be seen as an advantage as well as a disadvantage. When selecting stones (in terms of colors), pay close attention to UV resistance. Accordingly, the color selection of UV-resistant mixtures is empirically limited.
