Hi guys,im losing a bit of confidence at the mo in regards to painting and need a little advice,im not a fully trained painter but have picked it up as i went along in the bodyshops ive worked in as a panel beater/allrounder,the shop im in now for last 6 or so years is a small shop but very busy one and i wanted to start painting more so i paint about 4 to 5 jobs a week of different size,now,some come out well and others have a bit more texture than i would like and its that i want to get rid of really,not sure if its gun set up or technique.i was using a sata 3000 rp but it was a 1.3 and felt like a hose really,smaller jobs were fine but larger ones i got too much texture again.now i have a supernova not hvlp,and was given a few tips which were to run it about 1.7 bar and wide open fluid which is about 3.5 turns out,its a large fan so i pull it in a bit and was told or advised to get a bit closer than normal. Any thoughts on this folks as im losing my confidence a bit,we use mipa basecoat solvent and either a clear called sprint or sometimes max mayer,also it looks ok when in booth but seems to dry in a bit the next day,not sure if i have had basecoat a bit thick maybe but some colours are hard to cover when mixed at 2 to 1 so i use it 3 to 1 .any tips on distance from panel and pressure to paint settings on either guns would be great.the boss who paints is allways too busy to give tips and guidance but his gun setup is weird and im not sure his set up would help me,he is self tought with no real training either but he aint bad at it.thanks carl.
i personaly don´t know a clear called sprint but it sounds like a fast clear , maybe it is more suited for smaller jobs like a couple of panels and you need to use a slower reducer for complete jobs , as there seems to be your problem.
It is also better to keep it to the products specs , if it says 2:1 then better use it like that , if a color does not cover in 2 coats than put it on in 3 coats , just watch your flash times that´s all , much better than playing with the chemistry side of paint wich is developed like that for a reason 😉
With a Sata rp it´s about 8inches distance , with hvlp about 6 inches and a 1.3 tip should be spot on for Max Meyer i believe , but i know it is good for most brands so that is not your problem.
You might need to play a bit with your speed.Cheers rob,yea its only used for 2-3 panels the sprint clear.but still getting too much texture,i think i maybe too close then as didnt know i should be 8 inches with the sata.i rekon i will try A,pull back a bit. B,move a bit quicker and give a bit less over lap.see how it goes. Will also try and keep it 2-1 on the base coat sides.
Any tips with the iwata supernova ? Its non hvlp.thanksGood advice so far and always mix according to tds,I would also check the tds for the clear you are spraying for reccomended fluid tip size.I disagree on 8 inches for the 3000 rp,the sweet spot is around 4 inches and close and fast 75% overlap with 30-33 psi,with wide open controls.Just doing this will help with the texture,the further away you hold the rp the slower you will go and you will get more material on the panel.If you go close and fast you will get thiner wetter coats with less texture.If you are in a downdraft booth a slower mix always works better for more than 2 panels and it will dry faster too.A slower mixture will go on thinner and wetter without the material build up vs a fast mix that you have to hose on to keep wet.I have been an rp guy for 13 years and have found close and fast works best with this gun no matter what clear you use.HTH and good luck :cheers
Thats great info jayson as i like to move quick just cant seem to get consistant results on the larger jobs,i didnt think about getting closer as thought it would be worse but will try it.ive been using a 50% overlap too so seems like i have over done it and that has caused the texture too,the problem in our place is its rush rush rush so i forget sometimes the little things i want to try out,i should write it down really the settings and techniques used and compare results.thanks again folks.
Hi jason i tried the 4 inches away and fast with less overlap on a trunk (bootlid) 2 x quarter panels( rear wings) and rear bumper today with the sata 3000 and a vast improvement to be honest,run at 2.2 bar about 30 to 32 psi,was a bit scarey at first but nice finish way less texture,bit on the trunk but not bad at all,will keep at it and hopefully get better with those settings.was way quicker too,thanks for the advice mate,carl.
Just to clarify you should be using MORE overlap not less 75% is a good place to start instead of 50% :cheers
You know, i thought about that today and came to think its more of a over lap surely !oh well i did more overlap anways.
On another note mate,i had 2 cars to paint today so had to use an old devilbiss gti ( not the pro ) for basecoat on one of them for quickness,and the siver on the one i did with that gun was a bit blotchy.i normaly set up gun at 2 bar and about 6 inches away and mostly they are fine but some do go blotchy and i have to play around to lose it.should i spray at say 1.7 bar with this gun and less overlap with silvers ? I use mipa solvent basecoat and the gun is 1.4 but it is a good clean gun even tho its about 10 years old,lol.
Not sure man,I used to use a devilbiss gti hvlp (north american version) and it was a pretty decent gun.I ran it wide open fan/material with 25-28 psi for base.I would use 75% overlap with slow reducer and a pretty good pace at about 6-8 inches or so,for the last coat dropping it a couple psi and increasing your distance another couple of inches and using a 50% overlap will help.Hey if the gun works after it is cleaned up who cares if its 10 years old,I use my 12 year old rp all the time :stoned
Hi jason just wanted to thankyou for your time and valuable imput,cant believe the difference i have got in my clearcoating with the sata by just getting in closer and wide open fluid at a bit more pressure,painted 2 silver cars today,the whole side of a mercedes and all the rear end of a ford focus and wow looks like factory finish with few polishing bits needed.i tried a bit less pressure on the second job around 2.1 bar and turned paint in a touch so almost 3 turns out from off and job looks amazing ! Cant thankyou enough as was gonna sell the sata !!!!!!! I know crazy,lol.
hmmm , going to try this too altho i have nothing to complain the way i do it now , there is always room for improvement 😉
Well its improved the way i clear for sure,just need to find the sweet spot with my other guns now lol.
Glad I could help,with rp’s close and fast is the only way :cheers
Jayson how many turns out do you get wide open on your 3000 ? I know there most likely all the same but i find if i turn fluid in a bit i get a slightly better finish. I have it about 3 turns out from closed.
I don’t own a 3000 anymore,I got rid of it but if memory serves me I would get 3 1/4 turns or so.The best way to set it is to open the knob all the way,now squeeze the trigger and turn the know IN,when you feel the trigger barely start to move STOP as it is now set.Sata reccomends all controls wide open and if this is too much you need a smaller tip.Try 33-34 psi wide open and let me know….
