Barrier Coats
 

I am stripping my bottom paint this fall - actually I am having a highly
recommended media blaster do the job. The guy recommends a "coal-tar"
barrier coat that he sprays on over the DIY "roll-on" systems from Interlux,
Petitt, etc... since I really don't know the difference I would appreciate
anyone commenting on it. Thanks. -DanO

When I first started looking into this when I bought my Contender, I
stumbled across this URL

which was very helpful.

should help you decide.

It is a black tar like product. It can do a adequate job as a barrier coat,
but it is a bitch to prep the surface when it is time to repaint the bottom.
The tar clogs the sandpaper and it takes 10 times as long as it should to
prep the bottom.

I would not recommend anyone use it, when the epoxy barrier paints are so
easy to apply.

I don't know what a "coal-tar" barrier coat, but it doesn't sound like
anything Interlux would adhere to....

I'm not sure I would characterize the "roll-on" systems as DIY... if
that in any way implies that they are less than professional
chemicals.

I was thinking about VC-Tar, it was a popular barrier coat used by sail
boats because it gave a nice slick finish. Once the bottom had to be
repainted it lost it appeal and people decided it was better to use epoxy
and then sand it smooth.

I reasoned that it was a tar like product, as well. However, it
appears that technology has also plasticized this substance.

I don't see it recommended for fiberglass, however....

I would consider Interlux and Petitt epoxy barrier coats to be DIY projects
and the product to be rolled on by paint roller.-Dan

Thanks. That's pretty much what I was thinking. -DanO

That's interesting information. The bottom guy that I am working with
offers it as a spray-on barrier coat. I had never heard of it before.-Dano

Harry,
Well if that's the case, we'll just have to tax the stuff more.

Sounds like a by-product of cigarette smoking...
