Natural stone walls are not just a unique eye-catcher. Depending on the construction technique and construction, natural stone walls offer many other advantages. When building a natural stone wall, a distinction can basically be made between the drywall and a masonry natural stone wall. Masonry stone walls are also grouted. However, not the first grout is suitable for this. Working techniques and materials used must be adapted to the existing natural stone. Afterwards, you will receive instructions on how to make a natural stone wall correctly.
Building natural stone wallsConnecting joints (from the wall to the floor) must not be grouted with joint mortar. Indoors, this gap is anyway an expansion joint, which is optionally grouted with silicone.
Make sure that you always use a flexible grout as possible. The high plastic coating compensates for the temperature-induced expansions of natural stones better and does not crack so fast. You should rely solely on branded products because of the high quality you need. Better once for 40 € grouted, as 5 times for 10 euros and then grouted with the high-quality grout. Keines Do not cover the freshly grouted natural stone wall with steam impermeability. The mixing water must be able to escape slowly.
Optimal processing conditions are also extremely important: never grout in the blazing sun, where the grout would harden too quickly. The optimum temperature for grouting is between 10 and a maximum of 25 degrees Celsius.
In the outdoor area, take care of frost-proof grout. Also keep in mind that neither natural stone nor joint compound can tolerate road salt.
Rainwater or stale water as mixing water may contain substances that damage the grout. Discolouration of the stones, bursting grout or even flaking pieces of stone can be the result.
