2 Pack "going off" times?

[JamesMcbride]

had my first experiences of spraying 2 pack laquer last night when spraying the rear 1/4 of the vectra. i was really pleased with how it went on, and the fact that it leaves a glossy finish straight away... however... it still dosent seem to have gone off properly, it isnt tacky as such, but if you put your finger on it and press, it leaves a finger print (obviously i did this on a bit that definately wont be seen)

When i was spraying it i had heat lights on it and left them on for about 3-4 hrs after to let it dry, then left it in the garage over night. went home at lunchtime today (about 11 hours after i turned the heat off) and it had still not completely gone off.

I mixed the laquer with hardener at a ratio of 2:1 as per instructions...


any ideas?

is the garage warm enough??????

btw if your 2pack try using some dulux gloss thinned down with hardner and activator in

give a **** off awesome finish

[JamesMcbride]

it isnt heated over night, but whilst spraying it was pretty warm, i certainly worked up a sweat anyway lol and as i said, i left it with heat on for about 3 hours after spraying...

Was it winter hardener?

Try a hairdryer on a concealed area and see if it sets it.

[GlasgowRob]

try my thing with the dulux when u get a chance

dulux exterior gloss with 2 pack hardener and activator

awesome

[JamesMcbride]

cheers guys, ill leav it a few more days before touching it, im sure it will be ok... it isnt that cold in there, and ive moved it out into the sunshine for the afternoon, so that might help

[JamesMcbride]

where do i get the dulux from? i will give that a go next time i need to do some spraying which will probably be on the corsa, so it will be nice to get it looking really shiney

b&q m8

just normal exterior gloss

works a treat i know a few profesional painters that have substituted it for proper paints

[GlasgowRob]

oh and it gives an awesomely hard finish once its cured

[JamesMcbride]

and its clear? like laquer?

[alistairk]

nope Dulux is only in solid colours. I know a guy painted a Volvo 740 in Dulux house paint, thinned with PETROL because thats all he had handy and it looked really nice and glossy.

Can't tell you how durable it is as the car was banger raced the following weekend LOL.

My mechanic drove round in an old MK2 escort van with a RS2000 engine in it.

That was hand painted with Dulux white - lasted for years lmao

[JamesMcbride]

lol nutters, i dont doubt that it gives a good finish, however... i dont think they will do any of the colours i need as all my cars are perlesant paint

[GlasgowRob]

get b&q to mix sommat up for you then


should be a bit cheaper than a couple of litres of 2pack as well

[Barwick]

haha lush i'm doing that on my next run around if the paint is abit tired. Them big 5+ litres are about 15 quid or something aint they in B&Q?

[Reverb]

What kind of brush do you use to put it on? or can you use a roller?

[GlasgowRob]

no you mix it with your 2pac thinners activator and hardener and spray it on

[Mike007]

Just a note for anyone thinking of doing this - for any 2-pack to be durable the mixing ratio must be adhered to quite strictly as smallish differences can make a big difference to performance. Without knowing what hardener you are using and the resin make-up of Dulux there is no way you can just guess the correct ratio.

In answer to the original question - in my experience, only ultra high-solids 2-pack paints don't dry within a short-ish space of time if the correct hardener and thinner and ratios are used. These need to be baked usually to cure properly. I doubt you used ultra high-solid paint though because it costs loads more.

At a guess you have used the incorrect thinners/hardener for the temp you were using it in. Hopefully leaving it in the sun will have sorted it.

Was joking - you ever SEEN a brush painted panel? and i think the 'artex' effect hasnt come into fashion yet on cars

[Tim Poole]

did the paint go off and how long did it take

[JamesMcbride]

seems to be ok now, will compound the slightly hazey bits tonight and see how it comes out

[Orange Peel]

Someone who lived near me painted his old Volvo bright yellow using a sweeping brush. He also changed the oil in the street and left the old oil draining on the pavement!

They very evicted soon afterwards!

[Tim Poole]

what heater did you use - just wondering because i will be respraying mine very soon

[JamesMcbride]

i used 3 500W floodlights and had a fan heater on the floor as well to keep it warm down there... the panel was warm to touch

[Tim Poole]

cheers
