Refit:  Winter 2008-2009

Winter 2008-2009 Refit | Friday, December 12, 2008/Saturday, December 13, 2008

When I chose to apply the high-build primer late on Thursday afternoon, my thought process had been to allow the primer a full day and more before attempting to sand it; past experience in cooler temperatures had proved that the primer was often not ready to sand the day after application.  So I had planned on sanding it on Saturday.  I also timed the application so that I'd be able to sand the hull on my day off and within an appropriate amount of time, since the epoxy-based high-build primer becomes very hard within a couple days of application and gets very hard to sand.

Therefore, I was surprised to find that by mid-afternoon Friday the primer was cured to sanding consistency; I did a small test patch, and had no trouble with the paper clogging.  So although it hadn't been my plan, I decided to grip the bull by the horns and sand the hull immediately, while the primer was in perfect sandable condition; it was only 1500, and since my regular work day had wrapped up a bit early, I had some time on my hands.

In about an hour and a half, I sanded most of the hull with 220 grit, leaving the transom and counter for later.  I sanded each section of hull to the point I thought was adequate, and then shined a light at a severe angle over the hull, which highlighted any areas that I'd missed. 

Saturday morning, I finished up the sanding with the transom, counter, and details--such as the area just beneath the toerail, and just above the boottop.  Then, I went over the hull with the bright flashlight again and sanded out a few areas that needed a bit more to remove the texture from the spray gun, leaving a very smooth, flat surface behind.



I had one area where I needed to apply some fine filler.  While sanding, I'd slipped and the palm sander's corner, with some exposed metal, created a 1" long scrape on the hull--operator error.  This was deep enough that I couldn't sand it out, so unfortunately this single area required a small application of Alexseal filler.  And do it goes.


I cleaned up the shop, as per usual, and hosed off the staging and floor.  With only a quick and light sanding of the tiny filled area ahead, I was ready for final solvent wash, tack-off, and finish primer in the near future.  As of this writing I had not determined my schedule for this work, as I had to account not only for the spray time but also a half day of sanding shortly thereafter, but I expected to spray the finish primer within the next week, hopefully sooner than later.

Total time between the two days:  1.5 hours Friday; 2.25 hours Saturday
