Hi-

I am considering the purchase of a sailboat which is on the hard. It has had a bottom job with 4 coats of interlux 2000e but then left like that, ie no other over coat. And the last coat of interlux 2000e was put on more than 6 months ago. What must I do now before adding anti-fouling? And is the 6 month maximum period for applying another coat of epoxy a hard fast rule?

Thanks!

Peter

Hi Peter,
Unfortunately the maximum recoating time of 6 months for coats of InterProtect 2000E is the absolute maximum (up until 2 years ago the maximum time had been 2 weeks). Therefore since the last coat of InterProtect 2000E had been applied over 6 months ago then you will require a good and thorough sanding with 80 grit paper to roughen up the existing layer and remove all sanding residue with Fiberglass Solvent Wash 202/Special Thinner 216/Reducing Solvent 2316N. Once the surface has been sanded and wiped clean you will then need to apply 1 additional coat of InterProtect 2000E and follow right up with your antifouling paint.
 
Hope this helps!

Exactly what I need to know, but unfortunately wish the answer was different...

I have an additional question regarding the 6 month span. If I roll/brush an additional layer of 2000E after a shorter period, say 4 months, do I then get to restart the window and gain an additional 6 months? Big smile
 
The reason I ask is because I am currently doing a blister job on my sailboat. I was planning on rolling/brushing a layer of 2000E Gray to high-lite any remaining scratches / gel-coat nicks  / pinholes. I was going to then use Watertite to finish fairing the surface, sand the watertite and immediately re-coat with 2000E white.
 
It may be 3 to 6 months before I can relaunch so if I can delay the final 3 or 4 coats of 2000E and the bottom paint until just before launch then it would be helpful
 
I realize that I could totally re-coat and then use the Micron Extra (which I plan on using) immediately but I would prefer to wait to put the bottom paint on just prior to launch.
 
Thanks

OK - I think I  found the answer to my own question at http://www.yachtpaintforum.com/time-required-to-wait-between-2000e-coats_topic256.html Tongue
 
 
At this first link, Joe@interlux states
 
"Your over coating times for Interprotect 2000E over itself is a minimum of "thumb print tacky" to 6 months without sanding. Therefore if the previous coat of 2000E becomes thumb print tacky within 30 minutes, then you can repaint. However, you do not want to paint 2000E wet on wet because you can trap solvents between coats that could affect overall curing.

When you move onto your CSC, you want to apply your CSC as soon as that last coat of 2000E becomes thumb print tacky to achieve a chemical bond."

I would interpret this to say that I could extend my time to apply the anti-fouling by delaying the last coat of 2000E until I am ready to apply the anti-fouling.  Star

 

I guess to be ultra safe I should put any additional coats of 2000E on within 4 months of previous coats. But this makes it sound like I could stretch the process out some.

 

So, a new question - If I do wait 4 months for the next coat of 2000E, is all that I need to do is wash with water to remove any dust / dirt build up? Or do I need to do a light 80 to 120 grit sand? Or buff with a scotch brite pad? Or just wash with 202 solvent wash?  Or maybe do nothing and just broom sweep the bottom? - So many options!! Confused
 
Then at http://www.yachtpaintforum.com/hot-coating-interprotect_topic357.html there is some additional recommendations  / guidance regarding "Hot-Coating"
 
Hopefully my "interpretations" are correct?
 
Thanks,
 
Bill A

Hi Bill,
As long as you are within your maximum of 6 months between coats of InterProtect 2000E, then you will only need to remove all dirt/residue from that prior coat of InterProtect 2000E in preparation to apply your next coat of InterProtect 2000E, there is no need to do any sanding as this coat will easily bite into the next.
 
Therefore you can stretch each coat of InterProtect 2000E as far as you would like until you have a better understanding as to when it is that you will be going into the water and then finish the job up.
