I think rev got it in one. Clear coat plus cold air will give this resuit I done the same.

On the money guys, too cold causing the clouding effect which is actually solvent burn in the thinners, it is still posible to paint even in this cold weather, however it means turning gun pressure right down and applying covering clear coats in lighter coverage passes.

 

The best way to get around this problem in cold weather if you dont have any heat avaiable to warm the spray area is to apply low presure half coats of clear progessively allowing the clear to flash dry for longer periods of time between coats, once you are at a point that you have enough coverage, leave the job sitting for an hour, come back use a tack cloth to make sure no forign material has setled on the finish, then apply a flow (wet) coat which is at 3/4 normal pressure, allow this to flash for 15 minutes, then apply one final flow coat at the same settings, this should eliminate any dryness in the primary coats.

best way is not to paint if below 15deg or wait for warmer days.

 

if u have to few 500W halogen lamps from supercheap will also help a great deal they like $35 on special for twins.

 

other than that any heater for the house.

 

ive painted 2pk on bellow 12C outside temp. though using 2 halogens and a cheap fan forced 2000W house heater got my shed temp to not bad 18C. the shed size is 8x8m so not small.

 

if on the open just use the halogen at around 45cm away from paint work.

 

what i found since ive been painting is there is no such method to follow.

few basics and than its up to you to adjust everything for the current situation.

including the mixing of the paint its dependant on temp,humidity,pressure, sweep method etc differnt brand of spray guns .... so everythign gets thrown out of the window.

 

ive had similar temps similar humidty same shed same equipment and paint but could never have same setting for two different jobs.

 

what works for someone will most probably not work for you.

 

Like sirpent said u have to try very slow and very carefull if u never been in that situation before. experience comes out in situation like these to do a reasonable job.

 

im sure next time this wont happen to you.

 

now time to sand it back down and have another shot.

Well i sanded everything back even the color coats and will try again. Wasnt to happy with the color that came out (dull, could be the actual color or could even be the cold weather). So gonna try everything again when its a bit warmer or when i go and buy some of those lamps.

 

I was curious to see how it would turn out in its previous state so i sanded with 1200grit paper and cut and polished it and it came out alright. Rev recommended that i leave the clearcoat to completely dry for a week before i cut and polish it. So that is what i'll be doing next time. I'm actually enjoying it and learning from my mistakes so thats good, dont really much like the prep work ie. sanding but its all worth it when you put a fresh coat of paint

yep to cold
