Paint reactions

Folks I need your opinions on the paint reaction i had this afternoon.

Clouding 3

It was done with Halfords rattle cans, so I have no infulence over flow rates or air consumption.
The workshop was warmed using IR heaters.

I still have ended up with dull almost milky pathes and some shiney areas.

Your views please and more importantly what can i do before applying the lacquer?

Regards Dan.

Was the air in the garage damp? . Some airosol cans can be a bit hit and miss. Very often too much thinner in the can will give a poor shine. Best to use a proper gun and compressor. I used a cheap Aldi kit with great results. Cost about £65. You may get a fellow builder to lend you his kit for a small fee.

The milky bits are caused by moisture in the air as a rule. When using rattle cans I place the can in a bowl of hot water I also ensure that the panel being painted is warmed up. You should be able to tcut most of it out

OK a follow on question. If I use a cutting compound (T Cut/G10) what steps would be needed to stop it reacting with the lacquer?

Dan,

Sorry to hijack your thread, but how many cans has that taken?

Chris


scutter - 31/12/12 at 04:28 PM

4 halfords cans would do it. I used 3.5

Not sure on the lacquer.
At Dan.

They look good other than the cloud. I was thinking of wrapping mine but I think paint is probably the way to go.

I hope you get the paint problem sorted anyway mate.

it is cold and damp that makes it cloudy ,heres a tip put you cans in hot water for 5 mins (i use boiling from my kettle heats the paint and gives them a lot more power been doing it for years and not had one blow up yet lol)
also if you wet over it is it still cloudy?

I wouldn't even try to spray in the current weather conditions in a normal garage.

One thing have found through experience is that Hycote "Double Acrylic" rattle cans are a much better than anything Halfords sell, the cans are tiny only 150ml but cover more area than the large cans. The paint in them is fantastic it covers better than any aerosol I have used and dosen't run.

I agree with Trident wouldnt even consider spraying on a a day like today it'll just bloom which is what its done by the looks of it, go over it withh 1000s grit wet or dry wet wait for a better day and give it another coat or try compounding it out.
Cheers,
Bob

Cold drafts do that to paint, have a fan heater blowing on it from as slight distance. I'm spraying out in the garage now and it's damp here too but the heater is keeping it good. Don't put too thick a coat of lacquer on at one time as it will also cause it to go milky. Halfords paints are quite good but don't mix them with other brands as they can then react.


will121 - 31/12/12 at 07:00 PM

Also I would say heating garage with IR lamps to spraying might not help as they don't really heat the air just objects, better of with convection/fan heaters and pre warm the paint can.


splitrivet - 31/12/12 at 07:02 PM

Base coat blooming is get roundable, whatever you do dont use clear in cold damp conditions or you'll regret it big style and have to start from scratch.
Cheers,
Bob


Peteff - 31/12/12 at 07:54 PM

If you are treating that as a base coat don't cut or rub it just spray a few good coats of lacquer over it and cut the lacquer back to a shine. Base coat is only supplying colour and should not be shiny anyway. Read your instructions though as some should be lacquered within an hour of application to get a good bond or your lacquer can peel off.

I can count on one hand the number of positive painting experiences I've had. Here goes my take:

If it's too humid (like it is in your winter, and here in our summer), you need a small booth (cardboard boxes taped together if necessary), and a heater to rid the air of the humidity. Heat the cans in water first, as already suggested. Even if you use very light coats, and sand up to 2000 grit later, you will find it goes milky due to the humidity. It can drive you completely mad.

Do wear a mask; if nothing else, the stuff you breathe, puts one in a foul mood!

Good to see you getting in touch with your feminine side Steve.

For info the G10 removed the marks quite well, just lacqeur to apply now.
Being water based the G10 sould just wash off!!!

G10 worked wonders. final coat on and a little polish they now look like this.

Very nice job with rattle cans, well done!

Just a little tip learnt when stumbling through my first paintjob, running a dehumidifier in the garage for a couple of days before painting does wonders for the finish.


fullpint - 5/1/13 at 05:09 PM

Come out looking mate.. Bet you are chuffed with the results..
Look forward to seeing the body done

It's been 2 colours since SVA, I'm not painting it now. Hmmm mind you would save on the polishing.

It's bloomed .. cold paint on cold surface . Ait cans in hot water prior to UAE and squirt on something to get flowing.


RK - 5/1/13 at 05:49 PM

That came out great! Congratulations!


ChrisLeary - 5/1/13 at 06:17 PM

They look fantastic Dan. Nice one.

Cheers folks, just awaiting the sheet of stainless to turn up to make some stone guards from then they can go back on.
