Hi all we use solvent base coat at work still but today i repaired a new fiat 500 and our scheme couldnt mix it so i ordered it in from our local paint suppliers.when it arived it was water based so was a bit worried as never used it before,as it happens i was quite impressed with it,coverage was great and 2 coats was enough to cover the primer then a half coat to blend,it seems to cover break throughs in the primer easy too and hardly any overspray dust too.i just used my air line blower to pass air over it to dry and worked well.
What is the best way to clean paint gun after normal tap water ? Cheers.
Ps i think it was lekler water base,any one have a lekler mixing scheme and whats your thoughts on it ?
I just switched Fromm ppg deltron 2000 to ppg envirobase it has been a great switch
Great color matches,covers better than solvent blends great and I have had no problems at all spraying metallic or solid colors,
For cleaning the spray guns I bought aquabase plus. P980-8212 water gun wash works great
Also if you want something smaller Sem sells an aerosol can waterborne gun cleaner.
After using tap water for cleaning your spray gun spray some acetone,then some lacquer thinner.
.after using ppg’s
Envirobase ,I would never go back to solvent….
ChrisX2, It really is good stuff, it might be a little more cost than solvent but imo well worth it, I use waterborne gun wash mixed 1:1 with tap water, works fine.

I’ve used a Lechler scheme in the past and was pretty impressed with it. I personally prefer DeBeer at that kind of price point but there’s nothing wrong with Lechler 🙂
We started to use PPG Envirobase this year and after a lifetime of Spies Hecker solvent based i just love the PPG Enviro stuf.
A friend of mine uses Nexa , also a PPG brand , and i like that a lot too , but since a while my neighbour paintshop uses Max Meyer , wich is also a ppg brand but on the cheaper side of the scale and i must say that it does look good , it´s not PPG but it can compete with most brands out there.
If you look for e cheaper alternative then i would give this a good look too.It is a bit funny when you put a coat on and it looks like its a different colour completely,then as it dries it goes to the colour it should be.
Say if a bit of dirt landed in the base coat or say the air line touched wet basecoat how is it delt with ? Can it be flatted out like solvent can ?Thanks for all your imput,any more on water base please throw them in the pot as would like to learn more on it,cheers carl.
I’ve used 4 brands of water base. All are quite different. Some of them are easy to sand and repair minor issues in the booth. With others it can be difficult or not possible.
Its very hard to comment on waterborne overall as everyone is so much more different than each other than the differences between solvent lines.
for denibbing waterbased we use these 3M discs : Paint Preparation Pads 150mm p/n 50590 , 1000grid – p/n 50951 , 2000grid.
You can stick them on a handpad.
hope this helps.
Do you do the denibbing dry or wet ? Also you can sand a nib out of solvent base paint and struggle to cover the sand marks if its a silver job,does water base have this problem ?
well , when i just started with waterbased i had to denib a bonnet and without thinking i used some water , not the smartest thing to do i can tell you.
It´s waterbased and you can tin it with water so no , denibbing waterbased needs to be done dry as far as i know.The filling in is much easier with waterbased then with solvend in my opinion and you always need to take care of not putting in deep scratches , therefor i always start of with the finest grid possible and make sure i keep it clean.
I believe that Jimmo has some nice explanitory vids about this on his channel ( one picture says more than a 1000 words so a vid should say it all 😉 )
This is his youtube channel ; http://www.youtube.com/channel/UCywKecHrSNa5bnSLc8IBrvg
I did tickle over it a bit with some 2000 but with very little water as habbit really as i do this before last coat of solvent base to smooth over any little fibres or tiny nibs in the base,as said its just habbit now,lol, sometimes a slight halo can occur so a little flat with 2000 damp before last coat sorts it .
Thanks for the link mate i will have a look at those.
