Okay, now what I'm about to say is probably going to sound crazy, and I'm not convinced myself about it. But here goes.
I read an article where an experienced sailor who has used this material stands by it. The material? House paint
. That's right, regular old, exterior acrylic house paint
. Sounds counter intuitive, but he said it's as good as any marine paint
, and better than most. And MUCH
I'm a professional painter and have been for over 25 years. I've used lacquer, poly, latex, acrylic, oil, and many others. I used to be a luthier (one who builds and repairs
guitars) so I know paints
quite well. And yes, the way they are making house paints with many different polymers and other such chemical properties is impressive.
I painted the underside of the metal canopy of a Sonic drive-in restaurant one time. The old paint was flaking and hanging like leaves in the fall. As I always do, I used a good quality exterior acrylic. With paints of this sort, if a small dime sized drop is found dried on a smooth concrete floor, you simply remove it with a putty knife. As a rule, it pops off quite easily. On this particular job, though, we had put in the additive Emulsa-Bond
As we were loading the spray rig
, apparently a small dime sized drop had hit my cousin's concrete porch and dried there. When I noticed it a couple of days later, I tried to remove it with my putty knife like I always do. It's easy. Usually it just pops right up. Not this time. It wouldn't come up. I scraped and shoved the rather sharp edge of the knife against the edge of the drop, and it wouldn't so much as scar. I'm not kidding, I almost had to hit the back of the putty knife with a hammer to remove it! I finally got it up, but its stubborn resistance to separation from the porch impressed me. Enough to put it on the bottom of a boat? Well, I don't know. It just seems wrong to put house paint, additive or not, on a marine vessel.
I guess, when the time comes, I'll check into it further and see just how strong each material is, house paint included ... that is, when I get a boat.
By the way, we checked on the Sonic three years later and the paint looked like it had been done yesterday.
