“It’s tapped” is the well-known motto of Oktoberfest in Munich. “It’s open” could be the motto of the Schrannenhalle near the Viktualienmarkt, which - after a few delays - was inaugurated in the middle of October. It became a superlative indoor market for everyone. No less high-class were the materials used; often very traditional and obliged to the trade. The brushed oak floorboards, for example, which were installed in the galleries by Schmid Bodenbeläge GmbH and customers of UZIN.

Bread and salt are brought along as a welcome gift when visiting a new building. But bread and salt are also considered a neighbourhood blessing that is meant to convey the idea of “getting along well together”. Not without reason did the new operators of the Schrannenhalle, a married couple by the name of Hammer, present the spokesperson of the Viktualienmarkt marketing team, Elke Fett, with this exact traditional offering under huge media coverage. Because the stall owners next door had already suffered fruitless, constantly changing owner concepts for the Schranne, which had trouble escaping bad press for some time. But this time, everything was going to be different:

Culture and concept instead of whatever and all-you-can-drink parties

The new investors spent a fair amount on rebuilding the Schrannenhalle. But the Schranne isn’t intended to be a hall of champagne and lobster: Rather, it will be gourmet food for everyone. It’s no coincidence, then, that the new slogan for the Schrannenhalle is: “A market for itself...and for me”!

But before market operations could kick off, there was a lot to be done in the building. Ventilation had to be overhauled and the screeds had to be restored. As a nice contrast to the iron construction in the hall, two new concrete cores were added in the south and north parts for the lifts. Plus two concrete slabs as galleries, which are adjacent and grant another view from above into the hall.

On the safe side, with layout proposals from Uzin 

No job site without a layout proposal! Markus Krieg dealt with the Schrannenhalle. As a technical field service leader in wood flooring at Uzin, he knows better than anyone that the floor for wood floor coverings has to be adequately prepared. It wouldn’t do to install any old wooden floor in the two galleries at the Schranne; rather, exclusive XXL-sized floorboards from the Markus Schober company in Tegernsee: hand-brushed and oiled oak boards with bevelled edges.

The head of application engineering, Ernst Wohlleb, who visits many job sites, even those outside Germany, explains why layout proposals are part of UZIN’s corporate philosophy: Every single property is different. Every single slab of concrete is different. That’s why we advise our customers right off the bat at the substructure stage and onward, and not just starting with our material order. And what’s more, we don’t just take responsibility for our products, but for the system as a whole!* After all, problems very frequently stem from the evaluation of the substrate, explains Wohlleb.

This is deeply appreciated by customers like Jürgen Schmid, general director of Schmid Bodenbeläge GmbH in Neutraubling. “Even in the face of difficult special constructions, the application engineers of UZIN don’t shrink away, but are flexible and are ready to guide us with advice and actions even on the job site. This always works magnificently, and because the human components and the chemistry are a fit, which is very important to us!”

Epoxy moisture barriers and coats of sprinkled fine sand

The Schrannenhalle project also came down to perfect operations scheduling: This is why extremely high points and labile constituents on the surface area of the concrete floor were bevelled in both galleries first. To prevent noise bridges and rigid bonding with compensation layers, suitable expansion strips were applied to all rising components. Then the actual flooring construction began:

Step 1:

In the first step, the 2-component epoxy moisture barrier UZIN PE 480 was spread onto the concrete floor with a notched trowel (size B 2) to combat capillary rising moisture, and then rolled on with a nylon fibre roller to produce an evenly sealed layer.

Step 2:

Next comes the second layer of epoxy moisture barrier UZIN PE 480, which is applied with the nylon fibre roller. Tip: If this second coat is mixed with the UZIN epoxy colourant in advance, it will be easier to determine where any is missing.

Step 3:

Finally, the area primed thus so is immediately covered with a generous sprinkling of quartz sand UZIN fine sand 0.8. “This has to look like a beach in Hawaii,” reads the extremely vivid specification from Ernst Wohlleb. It is not made clear whether Jürgen Schmid’s employees know what it looks like in Hawaii. Here’s what for certain: the contractors from Neutraubling did as they were told and sprinkled the fine sand with abandon. Why is this important? The quartz sand cannot be coated by the epoxy resin, because otherwise the mechanical binding, the anchoring with the UZIN levelling compound that will be applied next, can’t be guaranteed. If this bonding has solidified, the excess material must be brushed away with a stiff broom or, preferably, vacuumed up.

Bonded levelling compound and stress-relief board

The mechanical binding of the levelling compound to the sand is only ensured if the adhesive primer is carefully prepared as described. It must be concentrated enough that any static or dynamic shear forces can’t damage the overlying floorboard construction.

Step 4:

To level out the last uneven areas in the substrate, the fluid cement floor levelling compound UZIN NC 195 is applied in layers 3-20 mm thick using screw pumps. It’s important that this layer be allowed to dry properly. Rule: One day’s drying time per 3 mm layer thickness.

Step 5:

In the penultimate step, the UZIN Multimoll Fleece is adhered as a stress-relief fleece with the 2-component PUR wood flooring adhesive UZIN MK 92 S (notch size B 2), diagonal to the installation direction of the floorboards. An appropriate perimeter joint for acoustic insulation at all rising components should be adhered to in doing so, and the fleece should be rolled on firmly.

Step 6:

Now the floor structure is perfect for the last operation, installing the wood flooring. The 2-component PUR wood flooring adhesive UZIN MK 92 S is applied with notch size B 11 and the floorboards are finally bonded: 300 m² on each gallery. Adhesive residue should be removed with cleaning cloths, while they are still fresh. Incidentally, this is feasible for up to four hours after adhering.

Diaphanous loft ambience in the new Schranne

Now, where the remodelling of the hall is complete, iron glass construction, the first of its kind in Munich with its delicate ceiling construction, will be displayed to its advantage much better than before. There was frequent criticism that it unnecessarily isolates the two precincts, the Glockenbachviertel and Sebastiansplatz, from one another too severely. That’s why one of the most important criteria for the rebuilding was to create transparency: There are now glass doors every four metres, which are open all day long so that visitors can stream through them. The market stands on the ground floor, with choice products from local and surrounding regions, are visible from all sides and arranged into four groups. Oak and oiled steel set the tone for the interior.

The most prominent tenant in the new Schranne is no less than Michael Käfer, the delicatessen operator from Munich. He will be running a market restaurant under the name “MarktKüche” in the north gallery, connected to the Pschorr restaurant, where people can enjoy snacks. From there, the guests have an open view of the entire ground floor.


The word “Schranne” means “grain”. As such, the Schrannenhalle was once a grain market. Industrial building with iron and glass materials first allowed for delicate, translucent construction in the mid 19th century. At first glance, you might think that the Schrannenhalle is an old building. It was actually built between 2003 and 2005. However, it was modelled after a historic building that was established by the municipal architect of Munich, Karl Muffat, in 1853, and of which only the northern end still remains today. The historic Schrannenhalle was the first building constructed out of iron in Munich. www.schrannenhalle.de
