interlux paint

Can some describe the roll/tip method?

Re: interlux paint

Typically when polyurethane paints are applied with a roller, the roller leaves tiny bubbles in the paint. Using a roller can also cause ridges and defects in the wet paint. A brush is used to lightly "tip" off the paint after rolling it on.

Here is a link to Interlux and video on how it is done. They are applying two part polyurethane but the same technique is used for one part paints.

Re: interlux paint

I have done the roll and tip method. It can sometimes get difficult especially on vertical surfaces. You have to get a really good brush (to prevent shedding) and continuously keep excess paint out of it. Excess paint will cause some extra thickness to build up during "tipping" and that can cause runs. The secret to getting that perfect mirror finish is to put several very thin coats on while wet sanding between coats.

When painting the external hull sides this past week I tried something different. I purchased those smooth-surface foam rollers. The skinny 4" ones. The bubbles they produce on initial coating are much smaller than the shortest nap normal roller pad I could find. Most of the bubbles break very rapidly on their own. I would wait a couple of minutes (Times may vary due to temp/humidity) and roll over the area again very lightly with the roller being as empty as possible. I do this a couple of times. You'll know when it is good enough because you won't hear that "crackle" sound of the roller over the paint. You also won't create any more bubbles. All you will have is a dull surface that will level in 30-45 seconds into a nice glossy shine. That smoothes the paint out perfectly and I have yet to have a run doing it this way.

Re: interlux paint

I am making my first attempt paint my boat with Interlux Perfection using a small foam roller. Instead of rolling and tipping I used the roller to go over the area several times until there were no bubbles left.

The first coat has dried to a nice gloss with no bubbles but the finish isn't completely smooth. I wouldn't go so far as to call it "orange peel" but it is not as mirror flat as gelcoat.

I sanded the primer completely smooth before painting.Is this the best that I can hope for? I've never seen a boat painted by this method and the videos I've seen don't allow you to see in the detail I'd need to make a comparison. From 10 feet away it looks great but if I'm up close I can see some waviness in the finish.

Any Advice?

Mudshark -

Try a second and possibly third coat. Wet sand between. Two reasons: (1)You will notice that you get better with each application and (2) in my experience the urethane responds better to urethane than it does to the primer surface.

Re: interlux paint

Why not spray it?

Re: interlux paint

Why not spray it?

lack of proper equipment or overspray would be my guess.

Re: interlux paint

I used perfection to paint my boat. I used the roll and tip method and it turned out ok. Follow the directions! Don't paint if you only have an hour, don't paint if the wind is kicking up! I painted the boat with a helper, she rolled and I tipped. I did have to do some sections by myself and it was a little tough. I found that the natural bristle brushes sold at lowes and home depot were just as good as the badger hair ones I paid $$$ for. Get the widest brush possible, I used a 4" brush.

My only complaint was that you had to work really fast so that the sections you were doing would blend together. It could have been the color I was using (Rochelle Red) but the first coat definitely had boxes that I could see along the hull. I realized in the beginning that I am not a pro painter or anything but the results were better that I expected. There were a run or two and some spots that didn't look great, but that was only up close, from about 10 ft or so it looks great.

One last thing, spraying a coating of perfection is asking for trouble. Perfection contains chemicals that are bad enough in liquid form (cyanide is one of them), to put those into a vapor form is dangerous, not only to you but to the whole neighborhood!

The waves have occured because you applied the paint to heavy and it is sagging....been there done that.

Look familar, that was done with a sprayer. While spraying can be done rolling it out will take more time but the result's will be just as good

Here's a roll and roll vid. but a few thing's..i used a contractor's white closed foam roller from home deopt they are very dense and do not break up when in use. Secondly if you watch the vid you will notice i roll out paint for about 3 minutes, then come back and flatten it. It need's just a minute or 2 or three to flatten some by its self. Then taking a clean fresh roller do the final roll...you leave a very fine nap but that will flatten, use very litte flowing sovent ( I never reduced by more than 5%). It will take 4-6 coats to get to a final finish, so if make make mistakes at first dont fret just paint and learn how to do it. Finally when you get to a solid color now is the time to strive your best result's sand out all the imperfection's with great care mybe using 320 grit and then go for it....hopefully by then you will have learned the paint's properties and can lay down a glass finish.

Little hint High Quality you can see the stippling form and be flattened every thing is in real time

watch in standard quality watch in high quality

Nice paint job

Re: interlux paint

Thanks for the info. I will check out the videos. I might have been too hasty in my first post. The finish seemed to smooth out by the next day and was quite smooth and glossy. Not as smooth as new gelcoat but pretty nice for a first coat. I just sanded the first coat with 320 grit and hosed it down, dried it and then wiped it down 3 times with thinner. If the weather is good I'll put on the second coat tomorrow. I'll take pictures after I'm done. I now think it's going to come out really well. Thanks for the help.

Great job, nice pictures!

How do I post pictures on my threads like you did.
