Is this orange peel or dry spray?

[Edward Yemm]

Now I’ll try spraying from side to side with the 1:1 mix and lower my air pressure a bit. Then I’ll have a go with 120% thinner.

 

[Edward Yemm]

The gunman on YouTube did a video where he shows different mixtures, pressures and spraying distances for different finishes with 2k clear. I’ll play around until I get less orange peel for a start.

i normally paint with as low a pressure setting as i can get away with ,,,

 

[Edward Yemm]

I’m putting too much material on now. I’ve turned the pressure down to 27 lowest and 31 highest. Runs galore. I think part of my problem may be that I’m moving too slowly trying to build the paint up or I’m getting too close. I’ll try again. This time moving a bit faster.

 

[Edward Yemm]

Hmm? Not a massive difference so far. One I sprayed too slow and got runs. The other I moved the gun a lot faster and put on a far lighter coat. Still with lower pressure and still at 1:1. Both photos are of the basecoat as it was still wet. Temperature 18. Humidity 54%

Are you trying to get the basecoat to flow? If so you're putting too much on, basecoat should just go on lightly and build up the coverage with extra coats as far as I know.

No. Just trying to get coverage. If I move the gun fast or slow I’m still getting more or less the same result. I’m overlapping 50% as required.

How many coats? For me when spraying basecoat I'd still be able to see some of the primer through the first pass.

2 coats.

 

[Edward Yemm]

I’ve got to the bottom of it now. It’s not the basecoat that’s the issue. The following are all 1K lacquer sprayed over the base. Some of the base was mixed at 120% and sprayed in 22 degrees. Paint warmed up as well. Other base was sprayed at 18 degrees 1:1. Pretty much the same result. Acceptable finish, or at least one that will cut flat if preferred.

And then on another panel. This rubbish. I was moving my gun way too fast when I did this clear. The slower I got the better it got. Now I know that I must practice my clear coat technique. I know I should be aiming for 75% overlap instead of 50%. I’ll keep practising until I can get it on smoother all the time. I think I need to make a boarded section with an extractor fan and a filter and hang it down from a slightly opened garage door so it seals and I’m getting the overspray out of the garage so I can actually see what I’m doing. I think I will buy some battery operated lights and put them on the sides of my garage wall as well because at the moment I’m relying on over head flood lights and a head torch. I can’t afford to buy a non arching paint spraying extractor fan. Ill have to get a standard one. I’ll just do what I do with my hoover. Make sure it’s turned on before I start spraying. No start up arc. No explosion.

 

[Edward Yemm]

At the bottom of the panel where I could see the least, the finish is shocking.

 

[Edward Yemm]

Yep. Think I’ll fit a couple of lights to the wall. Too many shadows.

 

[Edward Yemm]

I’ll also have to start test spraying my clear. Making sure I’m getting a wet flow out with 1 second trigger. Don’t know why I haven’t already. Perhaps I need to turn my fluid out another turn or two for the clear. I’ll keep on practicing now I’m wiser to the problem.

If the vacuum has a brushed motor then lots of potential sparks. Do you have to thin the clear? Spraygun setup should be different for the clear than the basecoat

Maybe some sparks but switching it on before I fill the room with overspray hasn’t killed me yet. The 1k is ready for use. The 2K I used on the car is recommended 10% thinner. Next time I use it I’ll ignore that and use 20% like the gunman did. I don’t know how to set up a gun for clear if I’m honest. How do you do it? Thanks.

If mixing you really need a viscosity cup and thin it that way to manufactures recommended value especially if not spraying full time

I’ve got some viscosity cups on order. There’s no information about viscosity as far as I can see. Just mixing instructions on the can and a health and safety data sheet online. Technico coatings. Bit vague on their information. How do you set up your gun for clear? Wider fan than hand span? Fluid wound all the way out just before the spring pops out? My fluid on base was 2.5 turns out from closed.

 

[carbon]

Use the same method as you did for basecoat.

It may be ok when you have the same ambient temperature as he has in Australia
and a heated booth. But not sure you will get the same results in a garage in the uk
