Hull Paint

Filed under: Building - Painting — tomlarkin @ 10:13 am

Meryll tipped while I rolled the first coat of black paint on the topsides. The tipping left visible streaks but I’m guessing that’s normal for a first coat of black over white primer. Halfway through, the paint started getting tiny bubbles that left white spots after tipping. We tried adding some thinner but, although the paint flowed more easily, it made the bubbles worse.  It could be that it wasn’t warm enough (65F), or that the humidity was too high. I’ll wait for better conditions for the next coats.  It took about 3/4 of a quart of paint to do this coat.

Meryll wore a shower cap to keep her long hair safe. I bought her a brand-new respirator for the job.  The horizontal line of dots in the paint are screw holes for mounting the rub rail.

Starting to paint

The rolling box she’s sitting on has been a real back saver while prepping the hull for paint. I bought nice big casters so it’s easy to move around.

Finishing up



  1. Looking great Tom.
    I’m still curious about your door slides. How did you do them? I have a similer application that is puzzleing me.

    I started a new thread on WBF about my build – “Building Bolgers Champlain”

    Thanks for your inspiration – she’s looking wonderful!

    As for engines – I’m a commercial operator and have had great success with Yamaha 4-strokes I do oil and plugs every 100 hours, and pump, thermostat and lower unit every 500 hrs. No problems!

  2. Try a 3 or 4 inch black foam brush for tipping. Just sweep it by lightly – like a fairy’s kiss. Works great.

    BTW, I do it by myself – working right to left – roller in left hand, and foam brush in right hand. I get a nice rythm that way and the job is done perfectly -lickety-split.

  3. Those two part paints are very thin when they go on. You are going to need three coats. Great paint but I remember the first time that i ever used them I thought that i had done it wrong and mixed it up incorrectly. Don’t try and go back over it though, the next coat will cove rup those little thin areas.

    As for the foam brushes, I would advise against those the solvents in the two pack paints will melt them. Much better to use a good quality natural bristtle brush.
