A hygienic coating was required for the Budweiser Budvar Brewery in České Budějovice, a city in the Czech Republic, for application to the internal walls and ceilings in three areas of the brewery, comprising of both new construction and refurbishment.

The brewery required a robust coating to withstand high humidity, permanent washing down, combat mold growth from the presence of migrant yeasts and sugar particles present in the atmosphere during the brewing process. It was also important that the coating was water-based to ensure no hazardous solvents or heavy odour were released during the application.

Flexcrete products were selected as they have an excellent track record of providing hygienic protection in breweries throughout the Czech Republic. Biodex Wash, a powerful hygienic surface treatment, was first used to kill active micro-organisms before Bond-Prime was applied in areas where it was necessary to seal the surface.

Biodex HB, a waterborne, anti-microbial coating, was subsequently applied to the internal walls and ceilings due to its ability to actively combat the growth of bacteria, mould and yeasts. Formulated using state-of-the-art silver ion technology combined with the latest generation biocide technology, Biodex HB incorporates active in-film anti-microbial protection, allowing for the ultra-slow controlled release of active ingredients into the coating film throughout its long life span.

The waterborne nature of Biodex HB was an important consideration for this application, as the coating is low odour, non-tainting and non-hazardous with ultra low volatile organic content (VOC), so there was no threat of contamination from solvents or strong odour. Rapidly and easily applied by brush, roller or airless spray, Biodex HB was able to flow around pipework and other protrusions, providing a seamless finish with no joints or irregularities in which bacteria could otherwise thrive.

With a durable, easy clean finish much thicker than conventional paints, Biodex HB can withstand intense cleaning regimes and extreme temperature changes without impaired performance or cracking. The coating is available in a range of attractive colours, including special colours, and white was chosen for this project.
