Need help with rolling and tipping
2 Attachment(s)
Hello all:

I am repainting my boat by rolling and tipping. I am using Petit EZpoxy2 two-part epoxy finish. I'm having trouble getting the finish to flatten out. Also, the areas where the tipping overlaps is visible after the finish dries.

The past couple of days the temps have been 85-90 degrees with low humidity. Petit recommends 50-90 degrees for application, so it seems all is in order. I've been adding 8oz of Petit brushing thinner to 32oz of finish. I tipped the first coat with a badger hair brush and the second with a foam brush. Both left visible brush marks. I sanded down the first coat to remove the marks, switched to the foam brush, and ended with the same look.

Should I be thinning it more? Should I not thin at all? Any thoughts would be helpful. Tomorrow's supposed to be a few degrees cooler. Could the temp be the issue?

I have attached a couple of pics. You can see that the shine is good. The one of the transom shows the reflection of the rudder, but notice the brush marks at the right side of the transom. The other is my reflection. All would be fine if I was looking for some abstract artist look, but that's not what I'm going for. ;-)

Again, any assistance would be greatly appreciated.

Re: Need help with rolling and tipping
keep a squeeze bottle of thinner handy to 're-thin' your roller tray as you go- the temp you are working in is HARD to get a good finish, as the paint is flashing off almost as soon as it goes on. So, thin it more than you think you need to, and re-thin it from time to time, and mix SMALL batches- don't mix more than you can use in 15 minutes and take your time.
Squirt some thinner on your tipping brush from time to time as well, so that everything flows smoothly.

I'm very surprised the manufacturer says 90 is the upper limit - I've never seen it set that high. You definitely need more thinner or cooler weather.

I'm over in Greenfield, NH. IMHO, it's been way too hot to paint a boat over the last couple of days.

The brush marks I'm seeing tells me the paint isn't flowing properly. Add the
max amount of thinner recommened by the manufacturer.

Thank you all!! Looks like the weather's set to cool off in a few days. I think I'll sand her down again and wait until next week to attack it once more, with a higher percentage of thinner to boot! I will prevail.

Re: Need help with rolling and tipping
Its much to hot and it sounds like they do not have thinners for different temperates

I found 70 something degrees perfect

What are you doing for shade and dirt ?

That is one beautiful finish, Tom.

I have been having trouble with my two part paint, too. I'm using Interlux Perfection. I think my trouble is that on the days that I have had to paint there has been too much wind. I can't build a cover over the boat in my boat yard. My solution is going to be to lower my expectations. These modern paints are optical illusions. A few people in the yard have been blown away by what an awesome paint job I have until they get a closer look. The shine makes you think it is perfect until proven otherwise... That is my theory, and I am sticking with it.

Re: Need help with rolling and tipping
a paint job on a boat is nothing more than the marine equivalent of cosmetic surgery- acceptable is copliments from 20 feet away- better is compliments from 10 feet- perfect is compliments from 5 feet away.

Remember, you only see your boat when you are embarking or disembarking- worry about how great the cockpit and the decks look- the topsides are everybody else's problem. :)

Re: Need help with rolling and tipping
of course EZ-Poxy is not an epoxy but a LPU coating.
the fact that they call it EZ-Poly is a good clue on the low opinion they have of their customers' IQ... and at over $200 a gallon for an LPU coating that probably cost them under $50 to make, maybe they are right
