Sweden’s largest yeast manufacturer has selected a hygienic coating manufactured by Flexcrete to refurbish the production and storage areas in the company’s state-of-the-art factory based in Sollentuna, Stockholm.

Jästbolaget produces around 20,000 tonnes of yeast a year for bread and speciality products including sourdough and sweet breads. The company’s yeast manufacturing facility is one of the most modern in Europe with a huge fermentation tank added to the plant in 1980. During refurbishment, it was crucial that any products used would not taint any foodstuffs used in the manufacturing processes. It was also important that there was minimal disruption and downtime during refurbishment, in order that normal processes could continue as soon as possible.

Biodex Sheen – a tough, water-based, anti-bacterial coating with encapsulated biocide and silver ion technology – was chosen for application to the wall and ceiling areas as it is designed for use in food manufacturing facilities and provides a seamless, anti-microbial finish with active protection against the growth of mould and bacteria. As Biodex Sheen has a waterborne composition, it releases no solvents or heavy odours during application and is non-tainting and non-leaching so it could be safely used in this heavily regulated and controlled environment. Biodex Sheen could be rapidly applied over the existing substrate by brush and roller, which was an important consideration as there were various protrusions which the coating could easily mould around. Due to the vapour permeable and elastomeric properties of Biodex Sheen, it is able to withstand the extreme temperate changes used in the yeast manufacturing process without cracking, flaking or other forms of deterioration. Biodex Sheen is rapid curing and manufacturing processes could resume within just 24-48 hours of application.
