What paint should be used on pvc material?
I tried scuffing 1st, then cleaning w/ denatured alchohol, and using one shot, but the paint can be scratched off quite easily

The job entails about 50- 12" square panels in various custom colours. I'm after a satin finish rather than a gloss also.

In the past I've used vinyl ink on pvc, ... but it's so toxic/smelly and I'm needing so very little of many various colours here.

What product(s will best accomplish my needs for this job? Can I prep the panels somehow that one shot will stick, and then use some kind of dulling finish?

Thanks a bunch for any help.
Nettie

Nettie...1Shot doesn't bond to PVC very well. Try Deka Enamel...it is a latex acrylic (no bad smell).

Krylon sticks pretty good too if ya can get the right type some places have different formulas according to state epa laws.

oops didin't read all the post good,...ya may need to put a coat of satin clear over the gloss to get a satin finish.

Nettie. I painted a bunch of 1/2" pvc dimensional letters this summer. I sanded them with 300 grit sandpaper. I used automotive catalized spot putty to fill the edges and sanded that with 300 grit. Then I sprayed them with automotive basecoat/clearcoat. This resulted in a high gloss, very durable finish. If you were to use the basecoat only OR laquer paint you would end up with a matte finish. I don't know for sure but there might even be a matte finish clearcoat available.

Janette, I would have recommended the nasty ink that you used before. Understanding the several color deal, perhaps you could just wipe down the panels with the thinner(which will eat into the surface) Maybe that would prep for a better bond. along with the sanding. Maybe even sand first so that you get full surface etching. I have never had any luck with anything but the pvc inks that eat in myself. Method untested.....Jack

My first choice would be to use vinyl ink. I've got 10 year old PVC signs out there that still look good.

I've also had good success with using OneShot after I've mixed some Frog Juice with it. I used a 6:1 ratio.

Nettie- I have painted it in the past and just did a sign for out doors last week. I coat the PVC with Tycote first. Then paint with Oneshot. This is what the didtributor told me to use. It seems to work. The tycote dries in about 15 minutes. A hair dryer will do it in less. If you can't find the tycote anywhere e-mail me and I will get you some.

Nettie with a light scuff of fine sandpaper. Wipe with lacquer thinner, or denatured alcohol. Then use Chromatic ti-coat(waterborne Primer), like you would a banner, then you can use 1-shot.
That's what I will use when I do a faux painting on some pvc pipes to look like marble columns.

Hi Nettie,

I was going to suggest what Glen said, but he beat me to it. I've mixed FJ with one shot and had good results painting on glossy aluminum surfaces. I forgot to add the frog to one color, and it scratched off easily, but the rest stayed on great.

Another trick I've learned is to wipe the surface with a small amount of acetone. It really dulls the finish and gives the surface some bite. It might be worth an experiment, because I've only done this on aluminum, not PVC. If it works, it would be an easy solution.

Have a great day,

Sue

Hi Nettie,

I wrote an article for the March 2001 issue of Sign Builder Illustrated, on building with PVC, and I did quite a bit of research on paint. The engineers at 1-Shot highly recommended Chromatic Acrylic Ticoat Primer or 1-Shot 5005 White Acrylic bonding primer, top-coated with 1-Shot lettering enamel. 1-Shot also makes their 5004 Vinyl Primer which works well for interior applications, but is not recommended for outdoor use.

Hope this helps.

We always used Vinyl Ink in the past, but have switched to using the following.

Mix 40% Frog Juice, 40%-50% One Shot, 5-10% One Shot Hardener, and if your spraying add 5-10% reducer.

Good Luck!

Dear Miss Nettie,
I prefer the TiCote and 1-Shot because I Can mix anything I want colorwise. I have all the base colors. Chromatic made a dulling agent that was a varnish and the more you added the flatter it got. I don't remember the exact name for it, but Kent would.

Thanks a bunch everyone!

Since I had some Frog Juice in stock, I just did a little test adding it my One Shot.
Looks like a winner! Worked great!

I actually love the results with vinyl ink best.
Glorious finish, dries in no time, and is very durable, ... but for this circumstance, I thought another route would make life simpler.

Thanks so much for all the helpful replies & a speedy fix to my dilemma!
Nettie

You folks are bound to have adhesion problems if you keep cleaning with the likes of;

Laquer thinner?

acetone?

Alcohol?

Auto wax&grease remover?
Git hip folks, Rapid prep will NOT soak into a substrate ,only to gas off later (when your paint is tryin to cure)

You may not have the experience of some who have been painting "plastic,pvc,propylene,ethelyne,etc."

But then if you use Rapid prep, it don't matter if you had the experience or not !!

The main thing is " don't make the job any harder then it needs to be " !!

Hey Nettie I got in here a little late but it sounds lke you picked the best paint for the job.

That Vinyl ink penetrates so well it is almost vandle proof(you can't scratch it off)

I also spray it with Centari and it is every bit as good looking but can be scratched...I do like the finish however and use it a lot.
