Problem:<br />
Interior wet <strong>and</strong> dry interface of this Scrubber would receive extreme abrasive <strong>and</strong> corrosive wear from<br />
abrasive coal dust, flue gas <strong>and</strong> H2S04. Scrubber was previously coated with a Ceilcote vinyl ester<br />
coating.<br />
Solution:<br />
Vinyl Ester coating was firstly removed using pneumatic chipping hammers. Complete surface area<br />
was s<strong>and</strong>blasted to a SSPC-SP10 near-white metal finish. Following s<strong>and</strong>blasting, repair <strong>and</strong> coating<br />
areas were pressure washed with ionized water. A second s<strong>and</strong>blasting was require to remove all traces<br />
of oxidization. Complete coating area was then chemically cleaned using Cleaner Blend 300. Two coats<br />
of Brushable Ceramic were applied to a thickness of 15 mils. Each coat of Brushable Ceramic was<br />
allowed to partially cure for 4 hours. Following the 4 hour partial cure of the second coat of Brushable<br />
Ceramic, Wear Guard Fine Load was trowel applied to a thickness of 1/4”. Acetone was used to smooth<br />
<strong>and</strong> contour Wear Guard Fine Load following gel point.
