Sherwin Williams Emerald Urethane Paint
« on: July 30, 2019, 03:56 PM »
Hello Foggers,
I haven't posted in a very long time. I've been busy building stuff and  testing out new paints. Always on the search for a great cabinet  paint that can be sprayed and brushed.
This is a test of Sherwin Williams Emerald Urethane paint. The pen is there so the camera could focus on something.

Cheers,
JC

That looks really good.  I assume it was sprayed?  I wasn't able to get it to flow out well with two different rollers.  I added floetrol after the first attempt which slightly improved the flow out, but not enough to make me happy.  Brush worked better for me probably because I was able to load it up better than 3" short nap rollers, but it was still very evident it was brushed.  If you have any tips for a smooth hand applied finished with this paint, I'm all ears!

Adding extender really helps the Emerald Urethane flow out and give you more open time when you’re brushing it.

Have you done any durability testing? My clients Spec’d it so I didn’t do any durability testing before I used it.

Found out that this paint is based on the Pro Industrial urethane paint that sw sells. I was told that this has a pencil hardness between 4h and 5h after 7 days of curing under ideal co conditions.

You are correct, this was sprayed. As for brushing, I'm doing some testing with different brushes and technique. Sherwin Williams has also asked me to do this. The goal is minimal brush marks. I'll post my findings here. Stay tuned.

JC very interested in seeing your brush test results. As a DIY hack I'd love to have a high-quality brushable finish.

Thanks for posting & sharing your results.

What did you spray it with?
How was the gun set up? Did you thin it or use any additive?

Hi Alan,
This was sprayed with a Graco GX19, no thinning. 60 mesh filter in gun. FFLP208 tip, 2000psi.
This paint is tricky. Eventhough you are using a FFLP tip, you still need to have the PSI at 2000. Reason is you need to spray 2 passes of a fine mist and do not exceed 4 wet mils. Many people spray way too thick and paint remains tacky or takes a long time to dry. Remember, 4 wet mils is 4000th of an inch and is the average thickness of a human hair. I forgot, I'm about 12-14" from the surface and moving quickly.

Cheers,
JC

@JCLP, have you considered spraying Emerald with HVLP?  I'm interested in your thoughts on this.  Must admit that I'm very much a rookie when it comes to spraying finishes.

I thought about it but even with a Fuji Q5, you would have to thin approx. 30% with water. This will dramatically affect the hardness of the paint when cured. Because the level of quality that is acceptable varies so much from person to person, it is hard to determine whether thinning it that much would be acceptable to me, probably not. I'm very picky and I'm getting very close to factory finish. If I had an air assisted sprayer, I probably would get a car finish quality.

I use my Q5 for clear coats and very tin paint like the Duralaq line from BM and the Kem Aqua line from SW.

Cheers,
JC

Thanks for the good info. I really appreciate it. Paint is tough to spray. I sprayed out a sample of this for a project with my Graco 9.5 and have to thin it 25%, and it still did not lay out very well.
It was just for a color sample to get some ML Campbell matched off of so not the end of the world. But unless some one can give me their secret recipe, I dont think I am going to spray that out of my turbine again.
