Previously coated wine tanks

Many of the older wine cellars still have steel wine tanks in use. These tanks are typically decades old, and often have been coated on the exterior with many layers of a variety of coating types. On number of occasions we have been called in to advise on the route forward with regard to the rehabilitation of such tanks. After sterilizing and cleaning the tanks - Fungal Wash followed by Tornado Degreaser - it is possible to get a good look at what is being dealt with. Now rust can be removed and treated, before selecting a suitable top-coat. We have, in many instances, gone the route of recommending Druiwebakverf (Fruit-bin paint) - a quick-drying solvent based acrylic/chlor-rubber bound coating incorporating an anti-corrosive pigment. The acid resistance of the coating is a big advantage, and the cost relative to twin-pack materials is favourable. It can be applied to substrates where alkyd based coatings were previously used, which is often the case.
