You’re probably spending $1500 on the blasting and another $1000 or so for the
Interprotect, so the total is fairly reasonable. The blasting and Interprotect
are an investment – you should never need to do that again.
When the final coat of Interprotect is still soft – dry but not fully cured so
you can touch it with a knuckle and leave an impression but it does not stick
to your skin – paint it with a good quality of Interlux hard bottom paint. This
bonds to the Interprotect and forms the base for your Micron to stick to. I’ve
heard the process referred to as “hot coating” the Interprotect. (Bottom paint
does not stick very well to fully cured Interprotect.) Use a color for the hard
paint that contrasts with the color you intend to use (e.g. red hard coat under
blue Micron.). This also becomes a “signal coat” that will let you know when
the ablative bottom paint is sloughed off and needs to be painted again.
I use Pettit on both my keelboats – Trinidad PRO as a signal coat and Ultra SR
(was ACP 60)as the bottom paint. Around here that lasts for 3 to 4 years
between hauls for bottom paint. YMMV.
In the future you should find that the Micron will mostly be gone when you haul
for painting. And then you remove the rest of the ablative paint with a
pressure washer at 2000PSI or so, no sanding needed. Then just repaint with new
ablative paint.
Around here we used to go to the feed and grain store and buy a bottle of
antibiotic intended for use with livestock and horses – and add it to the
bottom paint at the rate of about 8oz per gallon of paint to inhibit the growth
of slime. I don’t even know if that is still possible. In recent years, most
everyone I know buys bottom paint that already has a slime prevention mixed in.
(Hence the “SR” in the name of the paint I buy. I would highly recommend you
buy whatever blend of Micron has the highest copper content, and also has the
slime blocker. Then if you use the boat every week or two, and get it up to
hull speed, whatever slime does appear will just slip away as you sail.

Subject: Re: Stus-List New owner wants a nice healthy bottom
I just contacted the nearest marina that can haul me and asked them for an
estimate. Seems to be in line with what others are saying. $4050 for the 35'
boat which includes:
1. Soda blasting
2. 4 barrier coats of 2000e
3. 2 coats Interlux micron bottom paint
Which Interlux micron, I didn't ask. Maybe I should. Any thoughts are
appreciated.

Ron,
Welcome. �I assume you mean the centerboard does not lower all the way? �I've
got a keel model. �my main concern would be the condition of the cable.
I had Osprey Marine at Herrington Harbor South soda blast,epoxy and paint the
bottom of my boat 1 1/2 years ago. �They did 4 coats of epoxy, 2 of paint.

Yes we are a little late, its time to get moving on this. �We are

Her bottom needs to be stripped, and I've decided to consider the soda

So after the soda-blasting what is next for the hull - do I need a new

blue to black and get a new waterline painted. �I would like the paint
to last two or more seasons. Primer? �Coats?
Also, the keel won't drop past about 80-90%. �Do I need to haul this
and put it high enough to drop the keel, or dig a trench under the
hull to drop it? �Sand, grind, primer and paint? �Any special pointers
for dealing with a sticky keel? �It retracts ok but just doesn't drop
all the way. �Not a big deal as we are cruisers not racers, but I
would like it to work correctly and, of course, not get stuck. �Please
don't tell me to drop the keel unless you really have to tell me that.
One last detail will be to paint the new name on her transom. �The
previous one is painted on. �Would it be best to sand off the name and
repaint the transom? �Hull color is smoke white (original). �Can that
be matched with new paint?
Finally, if anyone knows a provider in the Rhodes River (just South of
Anapolis) area that can do this reasonably and well I'd appreciate any
contact info on that.
And yes we will do a name change ceremony with champagne sloshed and
swallowed appropriately.
Thanks to any kind C&C sevants
