SofTop comfort flooring used at Turin University

Project/location Aula Magna Università Torino –University of Turin in North West Italy is one of the oldest Universities in Europe but continues to play an important role in research and training, ranking 3^rd in Italy for Universities covering these activities. This new build project in a lecture theatre in the faculty of Journalism and Literature project was part of ten-year construction project on the University site. For a modern floor finish in keeping with the design of the building a seamless finish was required – in total 301 m2 was installed in October 2020 with the Sherwin-Williams SofTop SL system and 61 m2 of Resuflor HB epoxy floor coatings.

The concrete screed sub-base was poured in August. A comfort floor type finish was requested which would have sound absorbing characteristics and have a soft touch. The products being used needed to have extremely low VOC (volatile organic compound) content and have no smell when being applied. The finishing coating of the SofTop system installed was Resupen WB Colour which carries the Eurofin Gold certification for indoor air comfort which confirms that the product fulfils low odour product emissions.

Product/technical spec including mechanical grinding and application of angle profiles using epoxy screed including the vertical parts.

Following preparation Resuprime pure epoxy resin primer was applied at 400 gr/sqm and broadcasted with a 0,3-0,5 silica quartz to enhance intercoat adhesion with the resin topping. Once cured the SofTop SL polyurethane self smoothing floor system was installed, which uses a body coat SofTop SLR Flex with a UV stable seal coat of Resuflor WB Colour.

Under the seated areas an application of a scratch coat using Resuflor HB was applied at 600 g/sqm which was abraded and then another coat of Resuflor HB Ral 7038 applied at 800 gr/sqm. Steps and walking areas were installed with SofTop SL system in Ral 7038 at 3000 gr/sqm to provide 3mm thickness.  

The whole area involved sanding the vertical parts to remove roughness of epoxy screed and drops of the resin from horizontal application. This involved using sandpaper with grit 60 to horizontal surfaces and vacuum this ready to be coated. An application of 75 gr/sqm of Resupen WB Colour Ral 7038 was applied. SofTop floors provide extreme durability and robustness, yet retain a soft and comfortable finish which is modern and attractive for diverse applications. Designed with footfall and wear in mind the finish is so tough it’s suitable for industrial areas as well as commercial and domestic facilities. The SofTop range offers a choice of 3 flooring systems providing varying thicknesses with degrees of bounce and flexibility.

SofTop SL used at Turin is typically installed at 2-4 mm thickness and is recommended for industrial and commercial areas subject to normal traffic. The system has a high wear resistance, high chemical resistance and medium resistance to shocks. The floor is suitable for dry areas such as schools, laboratories, corridor areas, electronic companies and health care facilities, etc.

Where footfall occurs SofTop finishes are good for the back due to the soft impact effect. With many traditional hard floors, regular users can find they experience difficulties with back issues from walking on an unyielding surface.

The soft finish provided with SofTop systems provides sound absorbing ergonomics, improving the acoustic properties of the building and reducing acoustic impact on other areas of the building. Systems deliver thickness for strength but with a soft finish which has excellent resistance to sharp objects, impacts, shocks and dropped objects, minimising the chance of remedial repairs being required.

Being self smoothing polyurethane SofTop is one of the fastest ways to lay a flooring system and to create a beautiful and durable foundation that completes a construction or refurbishment. The SofTop floor systems available can be ready to receive traffic after only 24 hours.

Because Sherwin-Williams systems are seamless and impervious to handle humid conditions, spills that stay on the surface can be easily cleaned and hygiene maintained, with no contamination.
