In today’s video, I wrap up sealing the skoolie bathroom and I install the towel rack and the toilet paper dispenser thing. It’s a fairly swift video, but I hope it serves you well.

Spar Urethane Application Notes
Many tutorials online attempt to make this process seem much more challenging than it really is. I found the process to be very simple.
First I used a large sponge and wrapped the sponge with 220-grit sandpaper. This allowed me to sand the strange angles.
The first application sucked up a LOT of the urethane. The fresh wood inhaled the product so the first layer involved using half of the can’s contents. The second one probably used 1/16 of the can.
Many people talk about avoiding bubbles and doing a very careful job with this. I found that information to be stunting. At the end of the day, watching videos where people used a ton of caution just held me back. The material goes on clear and I didn’t have any bubbles. At first, I worked hard to be very delicate with the material, by the end, I was slapping it on and spreading it out. Both methods of application resulted in similar results.
Testing the Seal
To test the urethane, I splashed water on the wood. If it had soaked into the wood, I would have known that another coat or two would be needed. Luckily, after two coats, the water beaded up and dripped from the ceiling. After I dried the water off, there was no visual sign that the water had penetrated the urethane coat.
