March 2002 saw the start of the holiday season at the Weißenhäuser Strand holiday park and resort, located on the Baltic Sea coast between Kiel and Fehmarn. The grand reopening followed a comprehensive modernisation period lasting four months. Situated directly on the Baltic Sea with its sandy beaches and typical north German beach chairs, the holiday park also offers its guests a tropical bathing experience – with temperatures of 31 degrees, towering palm trees and warm water. What seems like a contradiction blends together perfectly.

“South Sea on the Baltic Sea” is the motto of this completely remodelled tropical resort. With a floor area of 5,500 square metres, the palm trees, aquariums, terrariums, ponds and a waterfall are reminiscent of a jungle landscape. Going to a swimming pool and doing laps in a 25-metre pool is a thing of the past. Nowadays, water parks such as Weißenhäuser Strand are in demand and appeal to both young and old alike.

It goes without saying that a project of this type – with numerous pools, a sauna / wellness area and food outlets – is a challenge for any tile fitter. Another challenge was posed by the short renovation and modernisation period at Weißenhäuser Strand. Planners from the Wulf architect office in Oldenburg and 15 other trades required only four months to expand and reinvigorate the year-round Baltic Sea resort. The complete renovation and modernisation of the resort was the first for 32 years, and cost the developers and owners of Weißenhäuser Strand around €12.5 million.

Renovation of tiled areas
Around 3,000 square metres of ceramic tiles were newly installed in the tropical resort. New tiles were installed on top of old tiles in the pool areas and sauna / wellness zones. The old ceramic tiles were not completely removed for two main reasons. Firstly, the old tiles were still in good condition (though no longer modern). Secondly, there were tight schedules in place which had to be met. Specially tailored installation recommendations according to the conditions and constant supervision of the property ensured that measures could be taken quickly and optimally.

Preparatory work
Before tile-on-tile installation could be made, the old tiles had to be thoroughly cleaned. Under the supervision of master tiler Stefan Gutsche, the “Quadrat Fliesen und Marmor” fitting team chose the RG 194 deep-cleaner – a solvent-free cleaning concentrate for old tiles and soiled substrates.

In places with steep ramps, floor deformations were filled in with NC 195 thin screed, levelled off and coated. NC 350 fine filler with a special fine-grain grading curve was used for deformations on the walls. This is suitable for full or partial surface filling, smoothing and repair of cavities, depressions, cracks and joints. Larger holes – for example, on old foundation sites or when using columns – were filled using NC 365 repair mortar. This mortar is suitable for smoothing and filling uneven surfaces, cavities and cracks, is waterproof, easy to mould and dries out extremely quickly, meaning it is dry for covering very soon after application.

Flexible composite seal
The NC 220 flexible sealing compound was applied to the old, cleaned tile surface in two sealing layers. This flexible composite seal is a part of the class III sealing system, and is thus suitable for damp and wet components in swimming pools and their surrounding area. If NC 220 is used as the flexible sealing compound, then only a reduced maximum water quantity of 5% is added to the product. A generous amount of sealing compound is scraped onto the substrate, then applied wet-on-wet and worked into a uniform ridge pattern using a notched trowel. Immediately after this, the ridge is filled in with additional material using the smooth trowel side and drawn out to form a closed layer. This process was repeated after the first layer had dried.

Installing ceramics in thin beds
Current requirements on hygiene, sloped surfaces and the leak-tightness of floor coverings require design features in the thinnest possible layers, which must still fulfil all prescribed necessities when directly combined with each other. The thin-bed method is suitable here, used together with sealing in combination with special ceramic coverings and flooring. Tailored Uzin products from the new Power range can be used here to create feasible and functional new floor coverings in the thinnest possible, plannable layers.

Uzin Power Plus low-slump, hydraulic-drying thin-bed mortar was used. As installation in wet areas has stricter requirements for the mortar, the C2 mortar was enhanced with Power Mix by the processor and mixed into a high-quality flex mortar. Alternatively, the fitter could also have used Power Flex – a factory-mixed flex mortar. In certain areas, the Power Fluxx flow-bed mortar was processed for the first time. This mortar is specially marketed by Uzin for ceramic floor coverings due to its flow properties. In the areas around the swimming pools, the new Hydrotect ceramic from Agrob Buchtal was installed in combination, as a cross joint and diagonally.

Ceramic jointing
Jointing of the ceramic floor covering was made with a prefabricated grout mortar – in this case a flex joint. Professionally installed jointing of this type with technically flawless material is waterproof – but not watertight.

New Hydrotect ceramic from Agrob Buchtal

According to the manufacturer, the new Hydrotect ceramic from Agrob Buchtal degrades bacteria and viruses, eliminates unpleasant odours and is easy to clean. This means it is virtually predestined for use in areas with critical hygiene requirements, such as swimming pools. Conventional tiles repel water. When using the Hydrotect coating, the water does not drip off – instead, it spreads out uniformly as a thin film over the tile surface. Dirt is then washed away by the water, making it easier to wipe down the tiles.

Information on the installation company

“Quadrat Fliesen und Marmor” was founded in 1992 by the master tiler Stefan Gutsche. The company now employs 13 staff. Stefan Gutsche distributes and installs exclusive materials. 40% of sales are generated from private residential areas, with the remaining 60% coming from commercial areas. In commercial areas, the company primarily deals with many public or semi-public projects, such as banks and municipal facilities.

Weißenhäuser Strand holiday park and resort
With its tropical resort, Weißenhäuser Strand is a holiday park with apartments, bungalows and a hotel – and not a high-rise building in sight. It is located in the beautiful forest landscape of Holstein Switzerland, five kilometres away from Oldenburg/Holstein on the Hohwacht Bay. The sweeping dunes of the Baltic Sea coast are right on the doorstep of Weißenhäuser Strand.
