I was able to put in a couple hours of work at the boat this morning. My efforts went into prepping the head and vee berth lockers for painting. I rely heavily on on
Don Casey's, This Old Boat for guidance on boat projects. Don suggests painting lockers as a method of perfecting painting techniques prior to moving on to more visible areas of the boat. The first step in his outlines is to scrub the fiberglass surfaces with a TSP solution. TSP (
Trisodium Phosphate) is effective at removing mildew and greasy residues from hard surfaces. Here is a series of before ==> during ==> after images from the locker the houses C'est la Vie's holding tank.
Before - The holding tank rests on the bare wooden shelf and is held in position by the grey bands. I am going to attempt to fit in a larger tank. New tank or not - I plan to remove the wood shelf and create a more finished and substantial mount.
During - The TSP is packaged as a granular powder that must be mixed with water. I scrubbed the hull with the TSP solution, right bucket; then used a sponge to wipe the area down with fresh water, left bucket. I continued to rinse with clean water until the fresh water remained clear after my wipe down. This took several cycles. I also used the shop vac to suck up water that pooled in any areas. Some water worked its way to the bilge. At the end of my cleaning session I used a water hose to rinse the bilge.
After - still have some sanding to do, but the TSP did a great job of removing mildew and dirt.
