removing bottom paint
 

Hey guys,

We have a boat with the bottom painted with International Ultra Hard
antifouling paint. It is in rough shape and needs to be removed and
recoated. The International rep says we need to remove it completely. Has
anyone had any luck with conventional paint strippers. I really do not want
to sand it all off.

Thanks in advance.

I just had mine done - sandblast. You have to find a guy with the
expertise to remove bottom paint. Mine used a special gun with a
super fine grit (almost like talcum powder but gritter - like a
jewler's rouge) with low pressure. The results were amazing. You
will have to do some sanding after for reapplication, but it won't be
as tough.

You might have to find a blaster who uses glass beads - they make a
brittle bead for this purpose.

Soda blasting is another alternative, but it's messy as hell. Water
blasting isn't an option as you have to use too much pressure.

There are solvents out there like EP-Strip http://tinyurl.com/2orn2u.
But that's for normal paint - harder paint, or double/triple paints,
take more. Compared to blasting it's slightly more expensive - say
25%.

Hope that helps.

Has anyone had experiance with the "Peel away " or "Star10 " strippers?
Both of these are supposed to remove antifouling bottom paint.

I am very leery of blasting since we have a wood boat. I have seen what
blasting does to wood if done wrong.
I used to work at the shipyard here in Portland and the local blasters were
right across the road. They ruined a lot of stuff. We also don't really
have that many yards that do the blasting. We have the ability to do the
stripping, I just want to be sure we use the right product.

Thanks for your input.

Peel away sucks - that's why I blasted the hull on the Ranger.

I've used Star 10 on refinishing projects here at the house - eh, just
like any other stripper.

I'm curious about something. You have to remove what exactly from the
hull - barrier coat?

It is Interlux Ultra Green A hard antifouling bottom paint. While I am a
great craftsman with wood, I am a neophyte when it comes to coatings for
marine apps.

That Interlux product is very hard - almost like epoxy in fact.

I understand your reluctance to use the blast method, but in this
case, it may be worth looking around for somebody with the skills and
expertise to do it. You might also look into soda blasting on this
stuff - might be more expensive and there won't be a lot of damage
with it.

You are going to hate me for saying this, but if you are dead set
against blasting the only way to really get it clean without sanding
like a mofo is burn it off with a propane torch. I've seen it done
with a roofing type torch or a shrink wrap torch. If you take your
time and do it slowly maintaining a constant low heat to peel it back,
you can do it yourself.

YIPE!!

I don't think a stripper is going to really work well for you on that
stuff because it is hard. Probably going to cost you more than it's
worth it - you could pay somebody to sand it for less money. There is
also a problem if you have some kind of substrate coating on the wood
- that may be a seperate problem.

Did you paint this boat or did you buy it for restoration?

I have heard good things about Peel Away but it is relatively
expensive compared to other strippers. Make sure you put plastic
sheeting under the boat regardless of which stripper you use.

The boat is owned by my partner. He had it painted several years ago. This
is just a routine maintenance issue.

removing bottom paint -PROBLEM SOLVED!
 

Well After a little testing I found that regular Jasco paint stripper melts
the bottom paint away in about 30 to 45 seconds. This is not the water based
stuff! I applied it on a test area and within 30 seconds it started to run
off. Just that easy. The Jasco is quite nasty stuff so long sleeve gloves
will be the uniform of the day. As an added bonus, it does not attack the
epoxy primer at all. So we will be able to remove the paint with just a
little sanding after stripping. It is fast and relatively inexpensive.

FYI

Thanks for passing that along.

removing bottom paint -PROBLEM SOLVED! Update, Breaking news
 

An update to the bottom paint removal. Be sure to use the Jasco
"Speedomatic" semi paste paint remover. The varnish and stain remover does
not work near as well as the Speedomatic.

Technique is as follows.

Apply as thick a coat as possible with a cheap brush, Let sit for appx five
minutes or until it starts to run.

Scrape off with putty knife. We are using some cheap plastic ones that
conform to the hull shapes better and they are disposable.

Use brush with a little more remover to scrub the area until all paint is
loose. Re scrape.

Use a rag thoroughly saturated with laquer thinner to remove residue. We
are using a two rag system, one for major removal and a much cleaner one for
final wiping. This will remove all the paint.

All that is necessary is to sand lightly per the new coatings instructions.

Happy stripping!!

Oh! adequate ventilation is mandatory!!!!! Both products are vaporous.
