[Public-List] Painting below water line

[Glenn]

Hi Dwayne,

I checked onto industrial barrier coats a month ago or so and found a good epoxy two part coating at Benjamin Moore.  Price worked out to 2 gallons mixed for around $200. (1 gal resin 1 gal catalyst) a lot cheaper than the 'marine' coatings on the market. 

Also I switched to interlux Trinidad hard bottom paint 6 years ago. Love the stuff.  I got 5 years out of first bottom job and virtually no residue was left when I repainted last spring. Takes two gallons though todo a proper job

I believe I am going to go ahead and put the effort in now to take it down to the gel and put a barrier coat down and then the ablative paint.  Hopefully putting the work in now will save me time and money in the future.  Any ideas as to how many gallons of barrier paint I would need.  Interlux Interprotect says it only covers 135 ft2 per gallon and needs 4-5 coats.  That would make me think I would need 2 gallons per coat??  Has anyone else used this or similar and how much did you use.

The paint held up well until about two years ago when small patches began to fail down to the prior barrier coat. I decided to take it back down to the barrier coat and start over.  I was quoted $30.00/foot to soda blast the hull which seemed a reasonable alternative to hand sanding 12 years of paint from the bottom.  The contractor told me that he hauled away over 300 pounds of old paint from the tented work area. I plan to apply three additional coats of two part barrier coat followed by a "signal coat" of black hard paint and a final coa
