i think the water based paint has a hardener which would make it 2 pack,
Supposed to be a bit dodgy for home use, needing breathing equipment etc
In the last few years the paint industry is being forced over to water based paint.......forceing my paint supplier to stop selling 2 packs ect.
So the question is why doesn't BOOTS the chemist get forced to change the paints they sell!
Sure we buy paint in a few litres at at time but thats it we spray one or two cars a year.
All those little pots of paint must add up to a lot more of the stuff.
Further more I think the stuff in the little pots is a lot more volatile than my paint.
It stinks the whole house out in seconds and its such a small amount.
What do you think?
buy your paint from boots then!
ironically if your painting a 1000 chairs and tables you can buy as much two pack paint as you want .
em...excuse my ignorance, but surely if you use water based paint it dissolves quite easily...in water. not much help on a car in britain.

I think it's was cellullose that's being stopped although if you need it to paint 'classic cars' it can still be ordered, or so
i'm told by my friendly supplier

First of all have to correct some totally wrong points here.. water based paint is not two pack - you can't have a solvent hardener in a water
based product!
Second, for the last 10-15 years motor manufacturers have been painting cars in water-based paints and two pack solvent clears on top (exception being
USA)
These are far, far, far superior to solvent base coats. They are highly stable, better match and cover very smoothly. The metallics don't move
when you apply the clear unlike the old solvent bases. I still don't understand why people always want to paint in solvent and clear or cellulose
rather than use these products. If you can prep and spray correctly the finish is so much better. Plus you don’t flat the paint coats, only the
lacquer and you use much less product.
Thirdly, they can be sprayed at home safely with a suitable standard mask. No need for positive air-fed. Also as long as you specify non-isocyanate
you can use high gloss super clear two pack lacquers over the top for a finish to match that of any car manufacturer. I paint Astons, Porsches,
Bentleys and Ferraris with these and you cannot tell where the new paint / lacquer is (this is usually not edge to edge by the way so is critical).
Now then back to your question Mango..
its because its down to the amount of product expelled into the air by the user. The EU measures it in tons, so you can see who they are targeting.
Bodyshops would fail automatically and hence have to use booths (as well as for baking of course) whose exhaust air is often quite literally cleaner
than that which is drawn in. Individual pots of paint obviously can never exceed these limits on their own as a one off.
Interestingly for those of us in the Smart repair area of the refinishing industry we are also required to meet these requirements but don't
produce enough pollutants per annum to exceed them so don't need to use filtered booths. However, if we were to use non-isocyante paints you need
a 14 metre exclusion zone and a 30min clean down time afterwards. There are great penalties if you don't do this.
Changing over to water-based paint is part of the overall master plan to reduce the level of pollutants. They don't have the VOC's (the
pungent smell) that you get with solvent based paints and which is strictly monitored too.
We all have to deal with the legalisation, but I for one would never go back to solvent paint. Occasionally though we have to paint RAL paint codes
onto trucks, farm machinery etc. Always prefer to get back to the water-based.

Wow! A nice bit of info there matey. Cheers.
Now can I bring the subject back down to my level? Can I paint my car with Eggshell Emulsion and paint it on with a cabbage?
