Concerns with EasyPoxy from Pettit. Please read.

[Darren Nemeth]

I am using Pettit's EasyPoxy topside paint as bottom paint. My boat is a 14 foot fiberglass tri-hull.

I was assured by Pettit in an email that if left to cure for 7 days before putting it on the trailer and if the boat will not be in the water for more than 2 days, its good for bottom paint.

Here is what I did. I used two part 2000E Interlux Interprotect epoxy sealer/ primer on top of my well sanded hull. Three coats plus sanding in between each coat.

Then I painted on Pettit's high build primer. Three or four coats with sanding between each coat.

Then I followed with three coats of EasyPoxy.

I just rolled on the third and last coat today. This is great stuff but I am concerned that after the 2nd coat sat the sun for three days the paint was still easy to put a scratch in.

Pettit says a full 7 days cure.

Can anyone comment on this paint's strength as bottom coat?

Re: Concerns with EasyPoxy from Pettit. Please read.

Ok so you are using a different paint then I am but I was curious to why it was going to take 7 days for the aint to fully cure? What are your temps where you are living? How long did you wait in between each coat you put on? Did you apply your coats as really thin layers?

I was not told by Interlux that I had to wait 7 days or any amount of time to put back on the trailer! Now you have me worried as to my timeline for putting the hull back on the trailer. I guess I will call them tomorrow and see what they say.

As for you in your process, I would follow there tips. If they said you need to wait 7 days, you have your answer. As to why you could easily scratch the paint I am really stunned unless you thinned out the paint too much when applying it. My first coat of paint was rock solid by the 24 hour set up time.

I guess I rolled on a good enough coat that foam rollers could put it on. Not really thick at all. I did roll and tip.

The second coat went on a day or two after the first. The third went on today, three days after the 2nd.

It has been 80 to 99 degrees here all weekend. I didn't use thinner. Just paint.

No rain. Just sun and heat.

Pettit says this in their EasyPoxy PDF file...

"Although not recommended for constant immersion, Easypoxy can be
used on the bottoms of dry-sailed boats that will be in water no more
than two days at a time. Allow the last coat of Easypoxy to dry a minimum
of 7 days before launching when Easypoxy is used in this manner."

Re: Concerns with EasyPoxy from Pettit. Please read.

IMHO mixing Paint Brands is NEVER a good idea. Why did you not just use the EasyPoxy undercoater primer? What application technique did you use? Roll and tip? Spray? Did you thin the paint? Thinner used? How thick or thin of coats did you apply? What were the temps and humidity? How long between coats? Did you follow these instructions...

APPLICATION INFORMATION
Stir thoroughly before use. Easypoxy may be applied by brush, roller,
conventional or airless spray. For brush or roller application apply without
thinning although in hot weather 5-10% Pettit 120 Brushing Thinner
may be added to maintain a wet edge. For best results on large, smooth
surfaces roll out using a short nap roller followed immediately by leveling
off with the tip of a brush. For conventional spray application thin 15-20%
with Pettit 121 Spraying Thinner. Apply one, thin even coat per day. After
an overnight dry, lightly sand with 220 grit sandpaper and apply a second
coat. Applying two or more coats in one day or applying excessively
heavy fi lms (greater than 4 wet mils) will lead to insufficient through dryin
of the paint and will yield soft paint films. For airless spray application
thin up to 5% with Pettit 121 Spraying Thinner. Utilize a .011-.015 inch
diameter tip for application. Do not apply Easypoxy on extremely humid
days (90F+ RH) or when rain is threatening. Do not apply in the late
afternoon when working outdoors as the wet film may be adversely affected
by dew. When working in cooler temperatures be sure the air and
surface temperatures will remain at or above 50F for at least 8 hours
after application.
SURFACE PREPARATION
Surface must be free of dirt, loose paint, rust, oil, grease, wax, soap and
any other foreign matter. Clean painted areas by washing with a solution
of 2 cups household ammonia per gallon of water and rinse well. Remove
existing mildew with household bleach instead of ammonia.

If you did not follow these instructions then.....

I'm just sayin...

Re: Concerns with EasyPoxy from Pettit. Please read.

Before and after sanding the bare hull I washed it down with Pettit wax remover.

I used the Interlux Interprotect 2000E because my boat had a problem with blistering. That dried perfectly fine. I sanded in between each coat and before every coat was rolled on I used a tack cloth and air compressor to get all dust off. That was followed with a wash down with mineral spirits and allowed to dry completely

The Pettit high build primer went on fine and dried perfectly.

The only concern is with the drying of the EasyPoxy. The 2nd coat went on very well with roll and tip but a full three days later I could still make a mark with my finger nail. Didn't add anything to the paint. When I did a light sanding in between coats it gummed up the sand paper.

How thick was the first coat and how long did you let it dry before you put on the second coat?

Re: Concerns with EasyPoxy from Pettit. Please read.

How thick was the first coat and how long did you let it dry before you put on the second coat?

Between the 1st and second coats was one or two days.

Pettit's literature says this..

DRY TIME (Hours)
To Touch To Recoat
90?F 11⁄2 hrs. 8 hrs.
70?F 3 hrs. 16 hrs.

The temps were in the 80s and I re-coated maybe 26 to 40 hours after the first.

The first coat was put on with a 9 inch short nap roller. Not really thick, IMHO. Just enough to coat the primer. I sanded before the 2nd coat so it possibly ended up to be 75% of a coat.

2nd and 3rd coats were with 4 inch foam rollers. The paint went on more evenly with those.

Now that I think of it, my car paint scratches also when I nick it with something. But so far this paint seems kind of soft.

I can't put this hull on the trailer until next Friday so perhaps it will be more than fully cured by then (?). That will make it about 10 days in the sun.

As shown in my pix, its in the direct sun for about 1/3 of the day and in indirect light the remainder.

Over night temperatures have been pretty high lately also.

Re: Concerns with EasyPoxy from Pettit. Please read.

That was your warning sign right there when you stated after your first coat you were having clumping when you were sanding. That should not happen. Were you wet sanding or were you dry sanding. If you were wet sanding you should not have ANY clumping, you water should be the same color as your paint product, just a fine watery substance thats all.

I am with Woodonglass on this one, cross contamination between products is forbidden. Use the same chemicals and products on jobs, no miss mathcing. The two types of paint systems are nothing alike and are chemically changing the drying dynamics of your paint.

I even noticed a difference between the Top Kote primer by Interlux to the Top Kote Interlux base coat. the base coat went on like glass and easy to wrok with in comparison to the primer. The technition with Interlux told me they have complete different characteristics and chemicals and they are made by the same factory but are designed to work together.

Keep us posted as I think youneed to call your paint company and let them know what you have to deal with.

Hello Darren..

Did you actually research the products ??

Hate to break the news..but IP2000 has a 14 day window of hot coats ( you dont need to sand ).

10 mils..means 5 coats of 3/8 nap roller... hot coat.. recoat.. so-on..

Now you want to switch it over to Petit..they make there own .. Petit Protect.. same thing .. basically...

What END result are we looking for m8 ? ..

You just applied some barrier coats to your boat bottom..

BTW... how smelly was your IP2000 to you ?...

YD.

Re: Concerns with EasyPoxy from Pettit. Please read.

Beautiful color by the way...

I was told many years ago by a paint manufacturer, forget which one, but they said about the same thing, but also added that it would take a full month to really harden out. But it was still usable way before then, but just not fully "chemically" hardened. Just my .02.

Hello Darren..

Yes. For weeks.

Hate to break the news..but IP2000 has a 14 day window of hot coats ( you dont need to sand ).

I sanded to give me a smooth surface. There were a lot of imperfections in the gelcoat and repairs I made despite all the sanding. The two primers partially acted as filler for imperfections. I sanded to make it more smooth.

10 mils..means 5 coats of 3/8 nap roller... hot coat.. recoat.. so-on..

The primers aren't the problem. It does not scratch through those. It must have been two weeks between the last coat of primer and first coat of EasyPoxy.

Its about 3 hours since I started cleanup and the EasyPoxy is dry to the touch.

Now you want to switch it over to Petit..they make there own .. Petit Protect.. same thing .. basically...

Now I find out

What END result are we looking for m8 ? ..

This is a Batboat meant for show and accosional boating. Mostly will sit on a trailer going cross state 2 or 3 times a year for conventions.

You just applied some barrier coats to your boat bottom..

Yes. Barrier coats using Marinetex and peanut butter/wood flower for filler and the two primers for filler/through thickness.

BTW... how smelly was your IP2000 to you ?...

Not much at all but I was outside with a respirator on all the time. Didn't smell as bad as poly resin, IMHO.

I dry sanded to knock off some debris that landed on the paint job and to cut down a couple of paint roller overlaps that looked bad. Sanding scratches also turned the color of the paint to a lighter blue. That way I could see if I got a good coat or missed spots after roll and tip.

It is. The shine is remarkable. Almost looks like it is wet.

The only thing I can compare it to is the fiberglass mascots from old family restaurants from the 60s and 70s. The boat glistens like a Bog Boy or Mayor McCheese in a Mc Donald's Playland from long ago. lol

Yea, that may be it. We'll report back in 10 days before the boat is to be flipped onto the trailer.

Hey Guys

I looked at the manufacturer's website and if you used the polyurethane product there are several reason's for your paint drying like it is. At our shop we spray polyurethanes and despite what the manufacturer may say polyurethanes are temper-mental. Humidity plays a hugh factor in the drying of these paints. If you look at a paint job in high humidity from an angle you might see a milky film on the surface. This is because the surface of the paint drys too fast and the underside of the paint cannot evaporate effectively. If you must paint in humidity you can add "retarders" to the paint which helps the solvents or chemicals to evaporate. I believe that this manufacturer has the "warm weather thinner" (150 Easy Brush Additive) which most likely has the retarder already in it. Also sometimes I find people are too cautious when sanding between coats and use a very fine paper and this does not give a good surface to bond. But if your paper is gumming up I think you have a humidity issue.

Re: Concerns with EasyPoxy from Pettit. Please read.

Daren, I used Interlux Brightsides top coat paint on the Hard Top project. It is a one part paint and took weeks before it was fully cured. Not too surprised that Petit takes a while too. Full sun and heat helps speed things up.

Re: Concerns with EasyPoxy from Pettit. Please read.

If what the Doc says is true 14 days is a very long time before applying anything to it. I relate this work to auto detailing as I detail for my car club. When you apply stuff to your paint surface substrates may or may not be able to breath depending upon the equipment and products used.

If you were supposed to wait 14 days before applying anything on top of it, you just slowed down the chemical reaction to the outside air to cure the paint. Now you are smothering it with more coats on top of more coats. It may never cure and if it does it wont cure right that is for sure.

I think it would be safe to say, you may have to strip all of that back off till you get back to where you started at. A much better alternative to moving forward and making things much worse and creating a heck of a lot more work for yourself.

Re: Concerns with EasyPoxy from Pettit. Please read.

Since I have selected Easypoxy as the paint to paint my boat with, and have been researching it for the past 6 months, and have searched almost every thread on iboats concerning the product I feel qualified to tell you that Epoxy requires a chemical reaction to harden. This reaction is affected by heat and humidity. With the High temps and humidity that we all have been experiencing lately I would not be surprised if it took your paint up to 7 - 10 day to harden. If after that it has stll not hardened then I would highly suspect it is having a negative reaction to the other products you have used.

I'm just sayin...

Re: Concerns with EasyPoxy from Pettit. Please read.

I used Pettit EasyPoxy topside paint on a small boat I painted a few years ago, I had gotten the paint for free, there was just enough to do a small boat. I primed the boat with standard automotive primer, a coat of filler primer, and rolled on the EasyPoxy. I got the same result, the paint felt soft, I could dent it with my finger nail after a week of sitting upside down in the sun. A buddy that runs a body shop made the suggestion of washing it with soap and cold water and letting it sit a few more days. It felt a lot better after washing it but also I went on vacation for two weeks right after that and when I returned the paint was rock hard. I'm not sure if it was just time, or the soap and cold water wash, or the several days of cool temps and rain we got here while I was away but it dried just fine.

Hello m8s...

You guys ..

The IP2000 has a cure " over or hot coat " of 14 days..

Meaning you can coat your bottom..wait a week ( lets say your going camping ) then " hot " or recoat WITHIN 14 days..

The recoat is 3 hrs min and 14 days max ( Your window for recoat WITHOUT sanding ).

PLEASE look.

And To say its not that bad... erm.. this is the nasty stuff..just mixing it gives me a bad feeling without a respo..

YD.
