The Alise Hotel in San Francisco
Waterproofing systems and floor and wall coverings installed using cutting-edge products.
The Alise Hotel is part of the Pineapple Hospitality chain. The hotel is located in a completely refurbished building dating back to the last century. The 93 rooms offer all the usual home comforts, as well as the traditional “old San Francisco” charm, with dark wood used to dress the walls, elegant lamps and bespoke fabrics. The colours used in the rooms go from pineapple yellow to grey, and the hotel’s vintage look coordinates with the design furnishings and the high quality finish of the white marble tiling in the bathrooms.
CUTTING-EDGE INSTALLATION SYSTEMS
The contractor employed to refurbish all the bathrooms and lay the flooring in the corridors, lobby and bar (total surface area 2,323 m2) proposed a unique solution to the property owner for updating the bathrooms in the 93 guest rooms. The contractor had seen a demonstration of the SHOWERPERFECT LM System during the International Surfaces Event trade fair in the United States and was convinced that it was the best possible solution to bring the hotel’s bathrooms up to date.
The SHOWERPERFECT LM System consists of a kit with drain fittings that are used in combination with the waterproofing membrane MAPELASTIC AQUADEFENSE. Before commencing work in the bathrooms and shower areas, the contractor had to repair the worn substrate. After removing the old flooring, some areas of the substrate needed to be repaired to make the floors perfectly flat. For this operation it was decided to use MAPECEM QUICKPATCH high-performance patch and PLANIPATCH cement-based patching compound.
The final levelling was then done with NOVOPLAN 2 PLUS self-levelling underlayment (these and some of the following products and systems are manufactured and distributed in the USA by Mapei Corp).
After this phase had been completed, work started in the showers by installing SHOWERPERFECT LM drain kits in combination with MAPELASTIC AQUADEFENSE for waterproofing.
The walls and floors in the showers and bathrooms were then tiled with white marble. Mapei Technical Services recommended setting the marble with ULTRALITE MORTAR PRO high performance cementitious adhesive and grouting the gaps with ULTRACOLOR PLUS, the most popular grouting product of the whole Mapei Group, which, thanks to the use of DropEffect® technology, forms grout lines which are highly water repellent and, therefore, less prone to becoming stained or dirty. The marble tiles came with a resin backing, so ECO Prim Grip was applied to the backs of the tiles to provide a suitable bonding surface for the Ultralite Mortar Pro. Elegant black and white tiles were installed in the hotel lobby and bar directly on top of MAPEGUARD 2, an anti-fracture membrane with soundproofing properties. These tiles were also bonded with ULTRALITE MORTAR PRO and grouted with ULTRACOLOR PLUS, and the same system was used again for the large tiles on the stairways in the lobby. In hallways and common areas on the guest floors, carpet was installed using Ultrabond ECO 120 adhesive.
