This shows the process and photos for the second of the three tanks we completed. The customer chose a Blome International Vinyl Ester trowel-mat-trowel system.

RELINING PROCESS

• First, we hung concrete blankets on the tank’s exterior because this project was completed in the winter. We continuously monitored the interior temperature with Flir thermal cameras to assure we kept the tank at the proper climate.
• Blasted off existing coating to SSPC-SP10
• Sprayed one coat of Blome Vinyl Ester Primer
• Used Blome CP-110 putty to fill in the pits and sharp edges
• Applied Blome TL-405 Reinforced Vinyl Ester trowel-mat-trowel system on the walls
• Applied Blome TL-405AR Abrasion Resistant Reinforced Vinyl Ester trowel-mat-trowel system on the floor and 6 feet up the walls
• Sprayed the ceiling with Blome TL-280 Flake Glass Vinyl Ester
