THE PROBLEM :
Corrosion is accelerated in salt-saturated air environment it will work away to breakdown the sheet metal. This will cause huge corrosion across the whole internal surface of the ductwork.
The internal surface of the ductwork is constantly under contact with the salt-saturated air however this is very rarely inspected only when maintenance is carried out.
Corrosion in A/C ducts is a huge problem due to the health implications to guests, a fire damper is a very important piece of equipment to prevent the spread of fire however these will corrode over time causing them to not open/close.
This must be a high-risk safety issue.
THE SOLUTION :
The solution to protect the duct work from corrosion is cleaning the corrosive duct with SUPER SAFE degreaser to remove the grease deposit from the duct, roughening the surface for a smooth bond and then spraying a 1.5mm coating of RZ-Ecoseal throughout the system creating a barrier between the metal ductwork and the salt-saturated air.
RZ-Ecoseal is a specifically developed waterproof sealant which is salt resistant and oil resistant. RZ-Ecoseal can be used in areas of high humidity and locations that are affect by harsh weather
RZ-Ecoseal has a high resistance against vibration due to the product when dry it is elastic.
