Sanding & Barrier Coat Application
Nov 16, 2024
I arrived at Sadler Point Marina just after 8am to get started on the weekend's bottom job goal. With the service yard closed on the weekend, I set up the mobile shop having the entire facility to myself. I had a power outlet ~20 feet from Biscuit, just behind the ice machine into which I threw an 8-pack of Gatorade. I set up the bottom 6" DA with the vacuum system, and then dressed into a Tyvek suit with the half-face respirator.
The bottom of the keel and the portions of the forward hull hidden by the trailer pads were my priority in the sanding work today, and so with 60-grit pads I began to take down and off what was remaining of the current antifoul paint. Biscuit being bow heavy, I slowly lifted the aft with the boat stands and slid out the blocking - later I would add a couple taller stands to the counter, helping to gain better access to the aft portion of the bottom. The also allowed me to gain full access to the bottom of the keel, save for an 8" section just before the keel turns up to the bow - this area, as well as the hull hidden by the forward stands, would be addressed later in the process.
As I begin removing the remaining antifoul, I noticed areas requiring more filler. They were predominantly on the bottom of the keel, areas taking abuse in shallow waters. The challenge was getting the work done in time (over the weekend), and applying epoxy-based filler would set me back 24 hours. After a visit my wife and son, and lunch break over, I grabbed some polyester-based filler from the local West Marine to address the gouges in the laminate. The polyester would cure in ~20 minutes, allowing me to sand the surface to fair and continue the bottom job. After a water-rinse and acetone wash, I made my way around the hull marking the areas needing fill work. I then mixed a batch of filler and slightly over applied the problem areas. While the polyester filler was curing, I mixed the first batch of barrier coat, Total Boat's Total Protect. The induction time for the barrier coat allowed me to work my way around the spot fills sanding the surface to fair.
With the spot fairing complete, I wiped thoroughly with acetone and prepped for the first barrier coat application. With a short nap roller, I made my way around Biscuit's bottom applying the first coat of epoxy-based barrier protection up to just below the factory-marked waterline. With Biscuit's home in freshwater, I contemplated raising the water just a bid for the reduced buoyancy. The factory waterline sat higher and out of the way from the trailer's pads, so I could leisurely address this back at the shop. I applied the barrier coat to the entirety of the bottom with exception to the portion of the hull hidden by the forward stands, the bow stand, and the forward blocking. A bit later in the afternoon, I managed to apply a second barrier coat to the hull. That would complete the day's work, and 99% of the barrier coat.
