Spraying Sherwin-Williams Waterborne

Hello, I will be in a Spraying competition this Friday, at Skills USA, I will be they painter for my school that attends, we will be using waterborne sherwin-Williams, which I have no experience with, or with waterborne at all. My instructor tells me not to think to much of it, he says just to over lap more and move some what faster then I would with solvent paint. This competition is practically rigged as the same school who hosts it, judges it. We don’t get any info on what we have to do until less then a week of the event. And all the schools do is practice on the project they give us all year which is a fender or door. So any tips would be greatly appreciated.
Thanks.
I’ve sprayed a few jobs with Martin Senour Vortex, don’t use it, but did a relatively in depth demo of it and some other manufacturers waterborne to see how they compared should i ever need or want to switch. Martin Senour and Sherwin i’m sure you know are the same product, just Martin Senour is marketed through NAPA stores. Best advice i could give you regarding spraying their base is don’t overthink it, and don’t worry about it. It isn’t too difficult. it is however a little thinner product i thought, and i’d bet you’ll find you need a bit more gun distance than you’re accustomed to with whatever solvent you spray. I thought it blended ridiculously easy, and it only took me my first panel to figure out how to adjust to spray it, and the 1st car i did was a silver Subaru. I’m sure they’ll show you all the basics before they cut you loose. You’ll be fine. Good luck to you.

Ok, thanks, I really appreciate it. I hope they do, my teacher has been trying to find out all the info on the paint, as in TDS, mixing ratios incase they don’t, as we only get about an hour and a half or so to blend and clear a panel. He’s gonna try and get as much info before Friday. He has sprayed PPG waterborne but not Sherwin.I’m just gonna try my best. I’m sure it won’t be too bed. I know I probably have more painting experience than most of them there, all they do is paint fenders all year, we actually get to work on peoples car and get a real feel of working in the real world.
I’ve used the AWX a little bit.
Not the best product out there…but it can me made to work. I recommend spraying medium coats, do not apply too wet. Download the tech sheet and familiarize yourself with the specs ahead of time. If you are blending, use the wet bed.
The problems you might face are applying too wet (this stuff will run and mottle easier than other waterbourne base), colour match (although this may not be an issue if you are matching it to itself, or just panel painting.
As far as not having experience with water, do not worry about that part too much. Just familiarize yourself with the tech sheet and what to expect from the water. If you have never sprayed water base before, the most alarming thing may just be how it looks out of the gun. It will look almost a slightly different colour and may look “wetter” and thicker than solvent, and as it dries will look a littly splotchy where there are wet/dry areas. Once the base is flashed off, it will look “normal.” Only other pointer is to make use of the blowers (to help dry the base coat). They can be used between coats and while flashing before clear. If you are blowing, make sure the blower is about 3′ from the panel and blowing in an appropriate direction (to allow for optimal airflow for the booth you are in and how the parts are arranged as well as ensuring they won’t blow dust from anything that may be in the booth.
Ok, I will for sure be looking at the TDS, many times to get as much info as I can. I will see how the first coat goes on and will make sure its flashed properly before the second coat. And as for the blowers my school doesn’t have them, we only spray solvent still, so its an unfair competition. But I will try my best to be in the top 3.
Why not have your instructor contact the Sherwin Williams rep and explain to them your situation. Sherwin Williams may give you guys a sample of their product to work with.
Most paint companies/suppliers would probably be willing to help you guys out
I will ask my instructor to call them tomorrow and see what they can do for us. We usually don’t deal with Sherwin, we go thru a place called Painters Supply, and they carry PPG, but it doesn’t hurt to try. Even if they don’t, I’m sure I won’t be to bad at it .
Man don’t sweat it. Water is much easier to spray then solvent. Like ben said get the spec sheets on it, & read it.I would assume that the host would give u everything u need. Here’s a few tips, make sure u have the right psi for the gun, & see if it needs a control coat(mets. Only). Try to keeps the gun 8 inches away, move a lil fsaster than u would solvent. If foir some reason they don’t give u blowers, u can always use a hand blower, just barely squee the triger, & like ben said, stand back & blow along the side of the pannel, never @ it. If u move fast enough, it should flash in bout 5-7 mins. Without blowers, with 3-5 mins.. Make sure u use the correct color sealer it will hide faster. & if your in a heated booth while u spray crank the heat up, it will flash pretty quickly, then turn it back down before clear. Cheat code, hahahaha. Man if your teacher ghas sprayed enviro, then it will be no problem for hime to get this.
Check out Sherwin web site lots of info.Good luck.
I spray Sherwin everyday, its not hard at all and I wouldn’t go back to solvent if I had a choice. Do you know what colors you will be spraying? Some of the reds and blues are extremely transparent, but other than those it normally covers well and blends fine. Make sure your gun is set correctly , put the first coat on wetter then follow with slightly drier coats, “stacking” the product until coverage is achieved. Make sure it dries before each coat, and especially before clearing or else it will wrinkle like a mother!! Do you know what guns you be using?? What state is this contest in, just out of curiosity? Anyway dont sweat it, have fun, and these contests dont really determine if you will be a good tech or not, you do that yourself.

It will look very blotchy or “cottage cheesy,” when it first goes on, dont worry about that it will dry flat and after clearing your blend area, it will look just fine. Do you know what guns you be using?? What clear are you gonna use, the 939, the dimension 5020, or the speed hpc15? What state is this contest in, just out of curiosity?

Ok thanks a lot for the tips, and no, they really don’t give us any info :blink: , I’m not sure what what they are gonna have me do, all I know I have to spot in a fender, if that, all they told was that it was Sherwin Williams AWX, and yes, I’ve experienced lifting before with solvent it sucks! And I will be using my own personal guns which are a Tekna Copper and a Tekna Prolite, as for the competition determining if I’m a good painter or not I agree, my teacher even said so, the whole competition is fixed, like I mentioned before, the same school who hosts the competition judges it, so of course they are gonna give it to there students. I’m in the state of Ohio, and in the 8th most miserable cities in the US, Toledo haha. I will greatly keep in kind all the advice you guys have offered.

I will, hopefully they can help us out with the blowers, I’m not gonna think to much of it, and yeah my teacher printed everything he could about the paint, and paint gun charts, also the mixing ratios, which helps so I won’t waste time reading or trying to figure it out. I guess they just hand out the supplies and send you out. No tutorial or anything. Their students all year, we get a week or so to prepare with the little info they give us. But I will try my best, and let you know the rests, unless they are horrible :whistle:
even if you can get ppg to bring out some enviro for a demo run, at least you get a feel for it.
