Sherwin Williams acrylon

[Don B.]

Anyone shoot this stuff?
It's a water based 2 part polyurethane. I've never dealt with water based anything besides the old prang watercolors in grade school or latex house paint. I'm wanting to paint my overhead garage doors as I am wanting to make the 20 yo ones match my 2 yo ones. Same brand of doors that started the same colors when all were new.
The reason for the water based was because I have 2 new fiberglass man doors to paint the same color to match these garage doors as well and the SW guru was worried about solvent based paints not being compatible with the fiberglass doors. Overhead garage doors are steel. This is my 1st time dealing with fiberglass house doors, most I have put in in the past were steel clad instead
Anything special about spraying this paint vs any other?

My take on this is to read the manufacturer's instructions labeled for the product. There is usually a statement about the substrates allowed/used. There will also be information about preparation. You should be okay with water-base poly but maybe do a test application and get another opinion.

 

[Stephen Newell]

I don't think much of water based paints other than latex on sheetrock walls. If you are going to use the acrylon paint be sure to use a bonding primer on the existing paint. A water based polyurethane isn't polyurethane at all. It's an acrylic coating that marketing has tacked the word polyurethane to it to make people think it's as good as a solvent coating.

It is a 2 part paint ( has hardener)

Yes I use acrolon on all my tractors and I'm implement restore projects. Can be quite expensive so ask for a discount price. Strongly suggest you use Duraplate as the primer. Both shoot very well, about the same as ppg omni. You will need the correct reducers for both. Only problem is there are limited color choices. Only issue I ever had was poor coverage with a custom made yellow, but all other colors worked fine with plenty of solids. Read the S-W data sheets available online.

2 gallons, 2 cans of hardener (quart size but each only has 19 oz in them? The "gallons" only have something like 107 oz in them.
That plus 1 gallon of the primer they recommended came up to $388. Yikes. I'm not into the 2nd "gallon" yet.

Yup. That's about what I pay at my dealer. The combined paint plus hardener should equal 1 gallon. You also need the reducer to thin the paint for hvlp guns. The acrolon "dries" within 48 hours but it will steadily harden over the next 30 days to rock hard.

Price is relative. A friend recently paid $3600.00 for just the paint, no labor, for his Chevy square body.

 

[Don B.]

Yeah I have a Dodge "square body" in the body shop now as well. I got a "total price" estimate which I about had a heart attack when he gave me the number, nothing broken down as to how much for paint vs how much is labor but I've heard here and there about paint prices from other sources including a thread I have here under "trucks" section among others
My first paint project ever with an HVLP gun was the bare frame of that truck.... Did that in my son's backyard since he was on 2 acres (he has since moved and now has 6 acres). and I didn't know how much problems I was gonna have with over spray and I don't have much of a backyard myself and didn't want problems with the neighbors. The sandblaster primed it for me, the paint I used there was also a Sherwin Williams industrial/ marine grade, that paint was $500 a gallon if you didn't have any "inside help" / which I did at the time, that gallon and it's hardener still cost me $250 for a single gallon with help. I didn't have as much help this time but now have an account at SW as a result of this painting job.

I hope to do the other side of the man doors today and a 2nd coat on at least parts of the overhead doors that I missed,
On thinner for the gun cleaning I read somewhere (might have been the literature that SW puts out about this particular paint); that said not to use solvents for gun cleaning, though I had to pull the spray tip off twice towards the end of the first coat and clean it in lacquer thinner as the air bleed holes started getting built up with crap that was making it spurt and generally spray funny. When I was done that day I poured out what was left in the cup (probably 1/2 a shot glass worth) and sprayed the cup out with water and filled it at the end with water and sprayed until it came out clear. (It is a water based paint) I then put the spray tip in a cup full of lacquer thinner and left it there. That was Tuesday and the spray tip is still in lacquer thinner.
This is the 2nd project I have done with this gun, I bought a cheap one at horror freight for that first one as I have a neighbor who used to paint cars on the side (he's dead now); and his last couple of paint projects he used guns from there and his comment was "they're cheap enough to throw away at the end of a job if you have to".
I haven't painted with a conventional style gun in a while either though I have several of those here collecting dust as well. Binks, devilibiss, etc. mostly picked up at auctions and garage sales so they were cheap to me, as well.
2 things about the painting I did this past Tuesday with the HVLP that I thought were bad/weird... One I wonder if it was because I used an HVLP the other I don't think was but could have been// first was that when I did the man doors and the jamb I had them laying flat on sawhorses. They came out misty/ "dry spray" where the overhead doors were done vertical hanging in place didn't. The problem with those doors was the bottom panel where I had to get down and lay on my stomach to do the bottom panel and didn't overlap quite enough and there's some gray primer showing thru as I didn't get enough color on there ... I should have raised the door so the bottom was at a more comfortable level. I did raise the door while I did the seams between panels where I had each split between panels at the point of that panel starting to go around the curve of the tracks to get some separation so I could get the spray stream in there better.

 

[Don B.]

I hope to do the back side of the man doors today and Im gonna move the sawhorses to under my clothesline poles where I can tie them up vertical "long ways" so I can spray them in the same position as I was able to spray the overhead doors. The side I did so far on each man door is the side gonna be facing out. I want to 2nd coat those at least although the "dry spray" look seems to have mostly leveled out once dry. They're still out in the backyard on horses and tarped over, I've lifted the corner of the tarp and looked at part of one and the dry spray effect seems to have largely leveled out as they dried. I stacked them on top of each other with a tablecloth between them and tarped them the next morning before I went to work because it was supposed to that day and I didn't want them wet yet at the time.
I'm also debating on using one of my conventional style guns for the 2nd round.
As I went along I mixed a gun cup worth/gun cup worth and a half, at a time. This paint has what's called a 2-1/2 hour " pot life" meaning whatever was mixed and not used in that time couldn't be used anymore . I was probably close to this 2&1/2 hours when the tip started plugging up even though the paint currently in the gun when the plug ups happened wasn't that "old"....

Last Tuesday's progress ... We were slow at work it was a perfect low to mid 70s day with no wind. A day we don't see much around here often so I took advantage and took off a 1/2 day to get this done
I had primed them last week Saturday, then it poured rain Sunday. Lucky the man doors are portable enough I got them inside before that came

 

[Don B.]

Don't know why the pix came out turned sideways when I put them up. In the 2nd pic with the single indented rectangle portion was one that I filled with JB weld and sanded and put a 2nd layer of JB on, and sanded again before I primed. The 1st round of JB full and sand plus the 2nd round of "apply more JB" was last Friday before primer Saturday, round 2 of sanding was Saturday just before primer.
The whole reason for this project was that I got a hailstorm and the insurance (don't get me started) allowed for 3 of the 10 panels to be replaced, 3 new panels mixed with 7, 20 year old faded panels would have looked like shyt and they wouldn't budge. I was going for complete new doors. I told the guys doing the rest of the home repairs that id rather live with a few small dents than a candy striped mismatch. Short of replacing both doors completely this was the only way I could fix them and make them match. And match the 2 year old doors on my attached garage at the same time.

Today's progress. A 2nd coat on everything I did Tuesday plus a heavy double coat on what is the inside surface of both man doors.... I found a way to hang them so I could get both sides.... I knew having clothesline poles in the back yard would come in handy for something... I hang more parts to paint from them than the wife hangs clothes from them
Even though they aren't tractors i work on them often behind these doors so I hope everyone is alright with me posting this kind of project....
When all was said and done I just finished up the first gallon of the 2 they sold me. Today the gun seemed like it wanted to cooperate better than this past Tuesday. I had to redo the bottom panel at least on the panel that's shown open as I missed some as I was trying to paint the lowest parts while laying on my stomach that day. Today I opened it so each panel was at chest level as I sprayed....

I mentioned it previously but to say it again, the acrolon will continue to harden significantly for the next 30 days, so give it time before installing hardware or banging on the doors. Also re-read the data sheet regarding time window for recoating. Doors look great.

 

[Don B.]

I think the recoat was up to 3 months . I'd have to check again. I think on the short end it was "after 8 hours". But I'm not looking at it at the moment.
Tuesday I had "dry spray" when I had the small doors flat on sawhorses today I got a couple of runs having them vertical.... None terrible. I did notice it darkened some between Tuesday and today as it hardened ...
I just finished the 1st gallon and 1st container of hardener with today's work. I'm gonna leave it at that for a while and see if I will need a 3rd coat but I really doubt it. I definitely covered the primer that was showing thru on the one panel so I think I'm good there.... Also from Tuesday's round I had a few " tiger stripes on the small doors that were much less noticeable today before I started than they were even Wednesday or Thursday when I went and looked at them.
