Becoming a spray painter?

Re: Becoming a spray painter?

Woodonglass I value your opinions a lot having read a lot of them along the way. You do great work and have equally great ideas all the time. But one reason I choose to go with automotive paints like Acrylic Urethane with hardeners and not the usual Acrylic Enamels like you suggest all the time is simply because you don't have to play with any chemical mixtures to gain a quality finish... WHY? Because the AU paints are mixed for the colors you want and the only thing you have to determine is the temperature you will be spraying in. If the temp and humidity are high, you use a slow thinner but the same volume. If the temp is in their normal ranges you simply use a normal thinner, and if it is cooler you use a fast thinner. It is all worked out for you without any guessing and trial and errors. The PPG paints I use have a fixed mixture ratio listed on their paint can labels for exact ratios. The usual mixture for AU paint is one to one. So one quart equals a half gallon sprayable. And AU hardened Clear Coats are two to one... No guessing is needed what so ever. The information sheets they give you even states what tip size gun to use and the air pressure as well. It also tells you how long it takes to dry to touch and tape off times and sanding or polishing times too... So much easier in my opinion...

Re: Becoming a spray painter?

I agree GM, The PPG P-sheets are some of the best around, they cover eveything, even compatible substrates and topcoats within their lines. And their reducers cover all reasonable environments. For example:

I mostly keep the 870 on hand, and adjust the room temp to the reducer, but if outdoors like i am on this project, ill pick up a range from 65 degrees to over 85..

Re: Becoming a spray painter?

I agree with all of the above but there's a price to pay for those products and...I don't like to pay the price. I've used the Cheapo Rusto' stuff for so long and have it figured out pretty well that I can pretty much shoot it in my sleep nowadays! As soon as it hits the surface I can pretty much tell what I need to do. Besides, I'm an old FART and change HURTS too much!!!!!:lol:

That is the ultimate deciding factor wood....

An RTS QT of rusto = under 20 bux

An RTS QT of Concept = over 200 bux

I apply whats needed, where needed.

Re: Becoming a spray painter?

YD I finally got a chance to visit the link you sent yesterday, it's been saved to my favorites. Thanks! Now I can add another tool to my growing list.

gm280 and zool a thanks to you also. And not just for the encouragement. As I said earlier, gm280 and zool have been a big help with this, starting with the help on selecting a gun and what was needed for an air compressor.

WOG after my first attemp I'm going to take your advice and look at those cups from HF that you recommended. Anything else that might be of help?

NOW, you guys are starting to talk way over my head. I know you guys understand what you're saying but I need time to catch up!

With the appreciations handed out I'll now try to give an honest impression of what I did and how it turned out.

I'll start with the object I'd chosen to do this. These metal cabinets were in sad shape as could be seen in the picture. I was trying to duplicate or at least get close to what I might run into when I get to painting the boat. 1st I stripped the old paint then wet sanded to finish up and to try and feather the edges of what didn't come off. Then washed off and wiped down again before using rattle cans to prime it. The front of the doors I really took my time and got everything nice and smooth. The back sides of the doors I hurried a bit more and didn't sand quiet as well. It shows. Which is fine because it gave me a much better idea of what to look for and what will show up.

With the actual painting for the 1st time yes I was nervious. 1st I took the gun and tried it with straight mineral spirits. For one to see how the adjustments work and to get a starting point for the gun pressure. Then with the paint mixed/thinned I shot some test patterns and though I had it pretty close from the videos I'd watched. Well maybe not! I'll have to work on this and experiment with trial and error.

While applying the paint I had to go slower than what I thought I would have to, to get an even coverage but after a little bit it started to feel comfortable. I was told from the beginning that this gun would be slow just by design. Which to is OK because I'm in no hurry and aint on the clock as it were. Not doing production work here. Though again as I was doing it I had a feeling that I was putting it on to heavy which may have been the gun setting or the way or amount that I had the paint thinned.

Over all I'm intrigued by the way it turned out and by what I've learned so far. As I stated I can see the mistakes and hurried effort in the prep work on the one side of the work. Great learning experience. Also got a long way to go to learn about paint and applying it. And these are supposed to be the easy paints to use!

Again thanks everyone! Hope your're not getting bored.

Aye .. 1 QT of Awlcraft or imron is like 60 bucks .. the hardener is like 30 bucks .. the reducer is like another 10 bucks. 100 bucks for just the paint. .. Possibly a little more depending.

Your prep is your prep .. it would take the same prep ( if not more/less for a good paint sytstem ) for any paint job.

The Post Prep/finishing is what will cost time and more materials.

Im sorry .. but if Rusto was all that good then we as pros would use it .. but its NOT.

The time frame and luster/finish of our jobs Require US to produce a perfect finish in a time frame. Quality is there .. time is there .. cost is a little more.

I hope you understand.

YD.

The only thing that Alkyed enamel ( Rustoleum, Valspar, Majic ect.. take your pick ) really lacks is a UV inhibitor, but it does make a nice hard durable finish. Keep it waxed with a wax that helps fight UV and it could last a long time. The oxidization time on Alkyed enamel is like 6 months unprotected. That does not mean it can't be used. It will just take a higher maintenance to keep it looking right.. My dad painted his old Starcraft Chieftan in a deep red color with Pasonno ( local paint manufacture ) Marine enamel which is alkyd and it chalked within a year but he never did anything to the paint other than spray it.

Personally, for topside paint, Acrylic enamel auto paint would be hard to beat. $30-60/gallon for basic colors add $12-25 for hardener and another $30 for reducer

Some of them DO!!!! Sorry, due to the night time sound was off and I didn't know about :facepalm: :D

Re: Becoming a spray painter?

I've my boat painted by Wood&Glass technique - rasto with hardener, it's came out just like showroom quality. If you follows all Wood&Glass instructions and have spray gun setup right - satisfaction guaranty.
BTW. I'll advise you to wear welding mask in painting process at sunny day. It's soooo shiny.

Oops, I guess this will just have to be a place holder ......

Now, where were we?

Paint, yeah, paint.....

I'll toast to that:

What I think I like the most is his close attention to proper mix ratios. This makes it so much easier to duplicate your efforts on the next batch.

Re: Becoming a spray painter?

Guys let's not get too carried away with this as I've PM'ED them and requested the link be removed as I 1st of all found it very offensive with little humor and the number of safety practices that are ignored is shameful.

 

[Woodonglass]

Re: Becoming a spray painter?

Yep, Totally agree!!!^^^^ Would NOT want it on my Thread either!!!! They can remove ALL my comments as well!!!!!

Thanks guys! It's not that I dislike colorful language or videos of people acting like morons but one just never knows who may come across this material in an open forum such as this. Again thanks for understanding and submariner thanks for removing the link.

Re: Becoming a spray painter?

Now that we have any newcomers completely confused let's move on.

The past couple days has been to hot to really do anything so yes I did watch some good youtube videos on painting. I found House of Kolor very interesting with their vids. Don't know that I will ever progress that far but I'm starting to understand what you guys are talking about with automotive paints. Even watched a couple of vids on how to put up a home made spray booth. Might be something to think about in the future also.

While at work last night was thinking about the cabinet boxes that will be next. I can get Rusto primer by the gallon for next to free so I'm going to try that next on the boxes. Any tips on thinning or tips on spraying the insides and shelves with the primer before I make a mess?

Besides just more practice and gun time I think it will help when it comes time to paint the interior of the boat as there are some inclosed areas that might be problematic when that time comes.

I think that vid was supposed to be a farce .. If not then it should be considered a farce lol. I didnt even have the volume on and thought to myself that the Title should be "How NOT to paint".

Back on track here ..

Absolutely one think you should do is contact Rusto support for the materials that you plan on using. They are very helpful.

YD.

Careful with those bigger sealed homemade booths and auto paints....can go kaboom..unless you want to spring for some explosion proof lights and fans...most dont blow up, but some do...and without supplied air, ppl pass out in them when painting alone.
