What this video covers

Repairing a delaminated deck sandwich requires removing the rotted plywood core and replacing it with composite fiber panels.1:09 After identifying water infiltration that caused the original plywood core to rot and the deck to delaminate, the repair process involves cutting out the damaged sections, cleaning the underlying surface, and drying the area with a fan.6:00 The installer uses composite fiber panels as a replacement core because they are rot-proof, flexible, and easy to cut with a multitool.1:19 The panels are bedded with reinforced resin and finished with a liquid gel-coat from Cabesto, which provides a smooth, self-leveling surface.16:15 Final steps include sanding the cured resin and gel-coat to achieve a flat finish before applying paint.18:40 The process is manageable within a single day, provided the ambient temperature remains above 20 degrees Celsius to allow for proper curing times of 20 to 30 minutes.21:17 Using high-quality cutting blades is essential, as cheaper multitool blades may fail at the weld point during heavy use.17:39
