Primers Sanding

An afternoon thunderstorm brought a bit of much needed rain to central Alabama, while also cooling the temperature from the upper 90s to the mid 70s. It was these conditions that I had for the sanding of the primer coat on the exterior hull. I was only a few minutes into the process of sanding with 120-grit paper when I found the conditions were less than ideal. The high humidity caused the primer to clog the paper fairly quickly. This is due to the titanium dioxide in the primer, which absorbs the moisture from the air and becomes gummy. The optimal technique is to prime and get the first paint coat on the boat in dry weather. Unfortunately, low-humidity days are few and far between in the deep South this time of year, even during a drought. So I pressed on, hoping for the best. The surface is fairly smooth, and was then wiped down and cleaned. All is ready for the first coat of true paint. Total hours 87.00.
