soda blasted bottom on sceptre
 

I just had my bottom soda blasted and will be barrier coating tomorrow. I am thinking of going with interlux offshore vc. This is a bottom paint for race boats that you can burnish. Do any of you guys have experience with this stuff? I am trailering the boat and need something harder rather than too ablasive.

Who'd you get for soda blasting?

Greg Silva out of Westport Ma, Southcoast Sodablast. Very nice job and clean, spent alot of time in preparation.

Mike - What boat is that one? You pick up a new sceptre?

Yes this is a new one. I just picked it up from a friend of mine. This was CSC member Jenalynn's old boat. This was the original for sale thread http://www.classicseacraft.com/commu...ad.php?t=23887

2 coats of barrier complete

If you dont mind me asking - how much for the soda blasting ?

700 bucks. Worth every penny. Lol..

2 coats of offshore vc by interlux. Going to need another coat. Not happy with this bottom paint so far. After 2 coats still not covering completely. Not happy with this paint for 300 bucks a gallon.

"Not happy with this paint for 300 bucks a gallon"

OUCH.......I know what you mean, you would think this stuff has gold mixed in as a filler!! Shooot, just a quart of regular Interlux is around $45.....jeeeez!!!

Yeah i went through 1 gallon and got 2 coats out of it. I have these what looks like spider cracks in the paint when it dries. I think it may be from the barrier coat not fully curing. I'm not sure but i'm not happy having to buy another gallon of this stuff.

Hey your Sceptre looks just like mine

Wow i guess it does Lol... What type of bottom paint do you have on yours?

a few dumb questions:


after the blasting - was the bottom finished sanded and solvent wiped down ?


coats of barrier ? alternated grey and white to get the needed thickness ?

when applying the coats of the barrier,did you wait till the barrier was kicked - meaning,use the "thumb test" - touch the epoxy with your thumb,does the epoxy stick to it ?

did you wait till the barrier was fully kicked before painting with antifouling paint ?

you are aware of the recomended application temps of the barrier coat,yes ?

I've used this barrier coat before and never had this problem. The barrier coat was cured cause i went all around the boat and checked. I'm working with 2 bullet heaters working all the time. I think it is this paint for some reason they recommend 3 to 4 coats and i only have on 2 . I will give it another week and then hit it with another coat to see what i come up with. There may have been some spots with the barrier coat that was thicker than others that may not have not cured completely.

usually:

what you're seeing is the end result of painting over top of epoxy that's not fully kicked...

This will give me a chance to try out my new porter cable sander on those spots.

I used Interlux ablative.Works fine in my area.I wet slip for about 7months out of the year.
Soda blasting is the way to go.Sanded mine by hand and will never do that again.

Thx for providing cost.. What is the going rate ?

I have been putting this project off but need to do it. It is one job I would not ever consider doing myself. I'll take the savings from all the other projects and blow it here..

What did you barrier coat with ?

Thx. Looks great !

I used interprotect 2000E which is ok just not very good with the bottom paint i used. I used interlux offshore vc it is a harder bottom paint and something that you can buff, does not have any antifouling properties. I will be trailering the boat so i thought this would have been a good pick. It's turning out to be a nightmare. Interprotect 2000E is suppose to be a non sanding primer, unfortunately it is not for the type of bottom paint i used. The manufacterer says that i got spider cracking because i was suppose to use an 80 grit on the 2000E after letting it cure for 24 hours. I did let it cure for 24 hours but i used 220 just to scuff it up. Doesn't seem to make sense to buid up a barrier coat and then sand it off.
