If you must, chemical strippers should be used in well ventilated areas, and an organic chemical respirator is a great idea. It will give you leukemia or other cancers if you breathe too much of it. The sandpaper will be good exercise for your arms, get you ready for paddling. > 2) Does anyone advocate removal of the fittings? This seems like it > would really lengthen the job. Is masking the fittings necessary? > Is there a good idea for masking the fittings besides masking tape? Removal of fittings will make a nicer job, do a better waterproofing of the wood around the fitting (where it's probably needed most) and make it easier to remove/repair the fittings in the future. It will also alert you to any rotten wood that needs repair before you reinstall screws. Drill out rotten wood, and use epoxy and a dowel to fill rotten holes and redrill them after it sets. With a drill and screwdriver bit it shouldn't take very long to remove the screws. > > 3) Once the old varnish has been removed, is there any > treatment that I > should consider before applying the new varnish? sandpaper only, remove dust with compressed air or a dry brush, and wipe with a tack cloth or rag damp with alcohol or lacquer thinner. let dry. > > 4) What type of varnish should I use? Should I apply with a > brush or dip > the wood into the varnish? How many coats? Best is Z-spar, but expensive, and Z-spar dries quickly so it's harder to apply. Any spar varnish with UV inhibitors will work though. Do not thin varnish. Use a brush. Don't apply too much at once, to the point that it drips or sags (such as dipping). If the wood is exposed to sunlight, 6 coats. If not, 2-4 coats is sufficient. Sand lightly between coats with fine sandpaper after it dries. if the sandpaper clogs and makes balls of the varnish, it's not ready to sand yet (*or you sanded a drip that was still sticky). Anything between 180-400 grit is okay. > > 5) How long should the job take? 1-2 hours of scraping and sanding, depending on how bad it is 1 hour per coat > > > Thanks for your help, > > Matt > *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
