Challenge                  

System applied within the past 18 months was not FDA approved and tainted 1,000’s of litres of wine. Removal of existing delaminating coating system and to provide a sound coating solution system to prevent future leaks and tainting of final product.

 

Chemco’s Solution  

We recommended priming with RH 800, a moisture tolerant damp concrete primer, followed by RI 800 for the deep pitted areas and any joins that require filling. Top coated using RB 500 and chopped strand mat to prevent coating from cracking when the precast pieces of concrete move. This system has an extremely fast turnaround and cure time.

The benefits include no odour during application and is approved for wine and beer tank applications.
