Ecodur 201: Coating a Keg Room


Beer goes back a long way. The oldest surviving beer recipe is contained in a Sumerian poem honouring the Goddess of Beer, Ninkasi, 3,900 years ago and ancient Chinese pottery has beer residue on pottery dating from between 5,400 and 4,900 years ago, shows it was brewed using barley and other grains.

The production process was primitive compared to today’s enormous stainless-steel vessels and piping. Countless millions of our ancestors owe their lives to drinking germ free beer as opposed to water which was very often badly contaminated in local wells.

Wood kegs have now been mostly replaced by steel barrels and it is all a highly efficient process. 35 billion gallons of beer are produced annually. Americans love beer and they are seeing something of a renaissance for beer with the continuing growth of craft beers all over North America.


It’s a common problem – hygiene and how to keep beer storage conditions as pristine as possible. Changing and handling hundreds of kegs inevitably results in spills and splashes of beer on concrete floors, rapidly leading to staining and attracting dust. Bacteria and fungi can take advantage, adding to the discoloration and odors.

The major sports complex client in Denver, Colorado, where up to 70,000 beers are served in a single event, had wanted a showroom quality, durable floor for its keg room and this particular one was the last in a series to be coated. They also wanted a new surface that did not involve emissions of VOCs and for it to be completely non-toxic with a fast cure time so downtime was minimised.


Castagra’s Ecodur has a history of protecting industrial, commercial and marine surfaces for 25 years with zero VOCs and extremely high adhesion to concrete in multiple applications, including frozen food storage facilities which resemble keg rooms and more complex areas such as kitchens.

Ecodur is very much like a very heavy-duty primer and it takes a decorative top coat to provide the showroom finish which is being increasingly sought even in industrial applications.

With a rapid cure time of just 24 hours, Ecodur greatly reduces down time often associated with conventional epoxy floor coatings which can take several days to reach optimum hardness. With no noxious fumes to contend with, the applicators only had to wear the most basic of protective gear and neither did the process displace workers from the immediate area.

Application Results

The floor surfaces were completely cleaned of significant staining as were all traces of organic matter, resulting in a dry surface ideal for maximum adhesion of the self-levelling manual primer coat of Ecodur which became tacky touch free within 30 minutes and fully cured in the normal 24-hour period elapsing from the last application. In this case, as can be seen, the high sheen, attractive finish was the top coat which was chosen because of its track record with Ecodur.


Ecodur has no time limit on repairs, as, provided the original surfaces is clean and dry, new repair coats will molecularly bond fully. It’s built in hardness rating which can be varied prior to application to suit most needs, remains permanently as does its flexibility, making it ideal for marine and tank use where expansion and contraction and even torqueing are frequently experienced.
