West Marine has a sale on paints this week so I'm starting to think about bottom painting. I have never done it before. The existing ablative paint has been on for 3 seasons (according to the previous owner) and still appears to be in very good shape. I'm figuring light sanding and two coats will be all I'll need. My question is, How many gallons do I need to cover the bottom of a Catalina 25 twice?

I was able to cover the bottom & rudder with 2 coats with just one gallon of paint. I had a extra quart standing by just in case but I didn't need it so I took it back.

I painted mine last year, bottom and rudder, and used just over 1 gallon.

I've put on two coats and used just a little over a gallon. That's where Bill's extra quart comes in handy!

I can put on a coat of vc-17 and it is about 2 ounces shy of a quart. Three quarts for two solid coats.

I use the West Marine ablative and a little less than a gallon does the trick. (Used to go with Micron but I get the same results with the way less expensive West Marine stuff.)

By the way, I don't recommend sanding off the old ablative; simply power wash the bottom and paint away. Thats what multi season ablative is for, in fact some don't even repaint every season. With multi season ablative, if you've still got color; you're protected.

Sanding is a lousy, dirty,unhealthy job and the less you sand it the better off your bottom will be in the long run.

My yard power washes the bottom when the boat is hauled, and in the spring I borrow my son's power washer and power wash the living heck out it before painting to prevent excess paint build up.

Maybe that's why I have no blisters on my '83.

I've found if you buy the proper brushing solvent and keep the paint thinned you to the right viscosity, you can get just about 1 coat to a quart.
Of course, it's all relative with an ablative. More paint = longer lasting.

It does go on a lot easier, tho, less dripping and smearing.

I rolled my paint on last season and used almost 2 gallons. Are you guys who get the bottom covered twice with a gallon using a brush or a roller? Sounds like I may have wasted lots of paint last year!

When using multi-season ablatives on my last boat, I applied the paint using short napped rollers.

Mark,

Where in New York do you moor? I'm in Patchogue and we haven't been allowed to touch our boat bottoms, sanding or painting, for the last four years.

I'm ready for the move.
