I'm no professional but when we sprayed my celica a few years back i remember it was only something like 30 mins untill the paint dried. I only really worked on the preperation so can't tell you what kind of thinners/paint ratio we used but if should definately not take a week to dry!
A little off topic but is that your 2 door ae92 of the FX variety in your avatar?

Acrylic should dry a lot quicker than that, where did the paint come from/ Are you sure it's not 2 pack without hardener?

It shouldn't take a week to dry. It should be touch dry in around thirty minutes, hard dry in 24 hours (for recoating if necessary) and cured for buffing some time after that (about two weeks minimum is good.
Is it like -20 degrees where you are?
How thick did you paint it (I see 50/50, but what size gun at what product/air ratio?)

Actually, if you're applying good at 1:1, the gun size is probably fine. Ignore this point.
The product/air mix is controlled by a screw in the back of the gun. The more you screw it out, the more product is drawn through the gun for any given air throughput. More product/less air will apply thicker/build faster.
The point is if the paint's too thick it'll take ages to set through. When it went on, did it seem thick? (ie. one spray clearly sitting proud of the surface of the last?)
Second idea: did you maybe lay a coat of paint on top of a half-cured prior coat? You should lay coats at intervals of no more than ~10min between sprays or a minimum of 24hrs between applications.
Hope this helps.

Also if the surface temperature of the panel doesn't get above 13 deg it will not dry quickly.
The spray tip size will dictate how much material passes through the gun, fine tuned by the knobs at the rear of the handpiece. They alter width of fan and air volume, some also offer control of paint volume.
A thick coat will always take longer to dry. So many thin coats at the right surface temperature is the answer. It should still harden and cure without any problems, but don't apply any different coats on until it has. That is if you are applying a two pak clear coat over it, it may crackle under the top coat.
Try thinning up to 150% thinners for faster drying, ( test patch) but the surface temperature is probably the more important thing here.

I always try to use flood light when painting as they seem to give off the right amount of heat as well as the obvious adavantage.
I was told that the drying time is directly affected by the hardener. I'm not sure if this helps but it's another veiw point at least.

Ive just recently painted my car with acyrlic and the mixture was not 1:1. It was 1 part thinners to 1.5 parts paint. Maybe your coast are to wet and its just gonna stay soft and not dry. Mine was touch dry in 10 minutes and you should be able to sand any problems bits 15 minutes after painting when using acyrlic.

Leighp,
Mate, you fears are looking accurate to me, it doesn't sound good.
I have written a tech article about spary painting acrylic on my site. Look under "Technical Info" from my main page.
http://users.chariot.net.au/~stmezz/celica.htm
A few points you need to know about acrylic. I usally mix around 70% thinners and 30% paint, so its thinned right out. This allows you to apply a nice wet coat to give a high gloss.
See my TA22 GT, (Simons Celica), I sprayed that beast in my garage.
You need a compressor of 8cfm minimum and idealy 10cfm to keep up enough air pressure. You should use a 1 litre pot, 2mm tip and around 300kpa air pressure for acrylic.
Each coat will dry in literally seconds. It should be touch dry in 2 or 3 minutes. Apply each coat within a few minutes.
After its done it will be dry quickly but you need to give it a few weeks to cure properly.
Make sure you are using acrylic lacquer paint and acrylic lacquer thinners otherwise it will not be good. I usually use PGP products which used to be Dulux. Very good paint in my opinion.
A complete car will use between 4 and 6 litres of paint and around 20 litres of thinners.
If it hasn't dried in a week, I would strip all the paint off and start again. Painting over that won't last. The minimum temperature you should paint at is around 18 C, below that and it will dry with a frosted dull affect. Max temp should be around 28 C, over that and the paint will dry too quickly. Also, don't paint in direct sunlight, it makes the panels too hot and paint dries to quick that way.
Good luck,
Simon

cheers all for the advice. i do recall that i had a heater behind the door for a little extra temp, and after a check last night it appears to have hardened up ok. I will look over it tomorrow (the 7th day of dry time) and due to lower air temps i am fairly happy with the results.
Simon where were u before, that web page is so good
mookie great idea with the flood light
again thanks all, keep all suggestions coming
NOW any panel beaters here? (pretty soon i will be a jack of all trades, mecho, painter, pano beater.........then a plumber and sparkie, tiler all thru toymods hehe.)

I did all the panel work on my car as well. I did a little bit about rust removal on my site too.
Let me know if you need any advice and I'll do my best to help you.
Cya,
Simon

guys wont dont you keep it simple and get it done in 2PAC???
no need to cut back and buff, dry over night, stronger pant better finish. i see everyone going acrylic and cant understand WHY??????
|
2Pac for the home user is NOT simple. Main reason is that that gear will KILL you if you don't have a full protective suit and positive air pressure mask. No paint job is worth your life!
If you want 2 Pac you need to pay someone that has all the gear to do it safely. Don't believe anyone that says a standard mask etc will protect you from 2 Pack because it doesn't. It will absorb through your skin and eyes. Remember kids, SAFTY FIRST....
If you have all the gear then 2 Pack is better than acrlic as you say. But for most that just want to do it themselves, you can get extremely good results using acrylic. If you saw my car I guarantee you wouldn't know if it was acrylic or 2 Pack.
Hope this helps,
Simon

i know all bout 2PAC, my closest friend is a panel beater/spray painter. they have a family buiness
now im trying to get a big head but i know its better & cheaper for me to go 2PAC cause it just cost me paint and a nught out for my mate paid by me.
iv seen acrylic jobs that DONT NEED cut and buff and your right you would never know the difference but im just trying to get an idea of why you guys dont go the pro way for it?

2PAC paint is bout $200-$300 for 4ltrs of paint, then there is the thinners, then the clear, clear hardener and thinners.
after you got the product you need the booth and spray painter. OH YEAH and its not good to sue acrylic primer and paint 2PAC on top, it can be done but not recommended
all up you would be looking bout $400-$600 in product, you can hire a booth from $150-$250. with the painter if you just want him to paint the car (you have it primered, rubbed back, masked up completely) they can take anywhere from $300-$500
after that you need to consider tow thee and back home of $50-$100
therefore it would cost anywhere from $900-$1500
yeah its alot of money but i recon its worth it

Generally acrylic isn't glossy off the gun, nor is it very strong with just the colour coats. You need to clear-coat it to make it glossy.

yes you can, you need clear and thinners
- OK since you have painted the car already the first thing you need to do is ensure the paint is smooth as a babies butt
- if not then rub it back with 800 or 1200 wet and dry (use 1200 if not rough at all)
- wax and grease it to get it clean again
- depending on clear bought depends on mixture required
- spray 1 light coat
- spray 2-3 good coats
- let it dry (again a week to be sure)
- cut it back and buff

Hey, that's cool. Best practice and what Joe Bob from Noble Park does in his ful-sik Gemini bro are two different things too.
Plenty of cars going around in bare primer waiting for the next pay check, but it's really not the best way to do it.
