Paint Inflatable PVC Dinghy?

What paint would you recommend for painting an inflatable PVC dinghy?

There are the typical paints made (supposedly) for painting an inflatable dinghy but the prices (as all boat stuff) are obscene.

Surely there has to be some paint found at Home Depot that'd do the job just as well.

What do you suggest?

Probably not. You'll want a "flexible" paint.

Fabric aircraft have been painted for decades with flexible paint.
Now flexible is in the eye of the beholder, automotive paint with some kind of additive that is made for painting rubber bumper covers is about as flexible as it gets and is often used on aircraft, but your not deflating it and rolling it up either.
Why do you want to paint it? How about covering it with chaps instead?

Re: Paint Inflatable PVC Dinghy?

I used the tuff coat system Tuff-Coat Inflatable Boat Restoration Paint on a worn out PVC inflatable. I thought it did a good job and held up pretty well. It did not not make the boat look "new" but improved it greatly.

By the way the best PVC glue I found was Cliftons Glue from Jacks Plastic Welding inflatable boats, self bailing rafts, catarafts, pontoons, inflatable kayaks, dry bags, paco pads, spill containments, culvert plugs by Jack's Plastic Welding Inc.. The Clifton Glue is a two part contact type glue that is heat activated. You mix it and paint in on both parts, let it dry, then put the parts together and heat them with a heat gun or iron. I had a PVC boat with a glued-on fiberglass floor. The strip holding the floor to the tubes was only 1 inch wide. I added some 4 inch wide strips of new heavy PVC on top of the 1 inch strip using the Cliftons Glue. I had to reglue some parts after about 2 years, but got several more seasons out of that boat before upgrading to a Hypalon boat.

Why paint it?

- Because I want to make it last longer.

- Chaps would be very nice if I had a $1,000 Sailrite LSZ-1 with Monster wheel (which I'd like to get...and for many other projects too) to make them. Yes, I know you don't need a heavy industrial machine to sew a few layers of Sunbrella.

However, Chaps will not solve the problem of sealing the seams from the outside and will have no effect upon the bottom of the dinghy.

My guess, initially, is that not many people have experimented in applying a generic paint by spraying or brushing it on.

Further, I've found that normal acrylic latex house paint sticks very well to vinyl siding.

Re: Paint Inflatable PVC Dinghy?

When I was in Tarpon Springs a couple of weeks ago a Gentleman travelling with his two teenage Daughters was cruising on a budget, a lot of his boat had house paint on it presumably to hold off UV damage, he had painted his Jib (furled) and Dinghy with white house paint, I assume latex. I didn't ask him how long, or how well it worked
Name of the boat is Enterprise if anyone knows him.

I asked why because if you wanted to put cool looking graphics on it, well that's different than wanting to protect it from UV, protection I assume you'd accept less than stellar looking if it was protective.

Relative to painting a dink....my guess is that once you've painted it then you'll have to touch up or repaint often.

I've painted PVC pipe many times (without and preparation to the pipe) and it adheres and endures very well.

A wipe down of the dinghy with Acetone would be a good approach prior to painting.

As they say....I just don't want to be the one to experiment just yet.

Can acetone be used to clean PVC

PVC primer (as used for plumbing) has the primary ingredient of acetone and the next ingredient is Methyl ethyl ketone.

Acetone evaporates so quickly it's not going to accomplish what you mentioned above.

Acetone or MEK is what Coleman recommends for priming an area to be patched before applying the patch with PVC cement.

Re: Paint Inflatable PVC Dinghy?

Well I've not used latex enamel house paint on a dinghy yet, only because I don't have one. I use a hard kayak. But I have used latex enamel to protect the jib. Works well and only have to touch up once every year or two. It's flexible enough and holds well.

I'm thinking it will last longer on a dinghy as it's not being wound up tight every day or two, like my jib is.

As others have said, DON'T use Acetone or pretty much any solvent on PVC. I think a light washing would be fine.

I painted my cap rails, well almost all exterior wood. Port cap rail I sanded, starboard I didn't. There hasn't been any real difference between the two as far as paint sticking.

I've already patched my dinghy using Acetone as a primer and it worked with no problems or troubles.

PVC patching cement is a solvent.

Acetone is also a solvent, just not as much as PVC cement. Your putting a patch of material over the old PVC. Acetone in the materials compatibility charts for PVC, will weaken the PVC.. But hey it's your dinghy, do with it as you want.

Do you have any idea how fast Acetone evaporates?

It only lasts a few seconds.

This still looks like the best approach-
