acrylic + cellulose paint ???

cellulose is 'hot', acrylic aint....to be honest never used it on cars, only for model making.

I know acrylic can be put on the top of others, but no the other way around....

What do you mean 'hot' ?

So why didn't you order Acrylic from the start, seeing as they don't have the full spec in cellulose? With this setup you are trying to paint a car with only half the paint.

Stephen.

I did ask why they supplied me with cellulose paint and they told me that this is the paint they use when they mix it themselves....

Strange that they have a Cellulose paint mixing system yet can't supply you with cellulose. We all know celly is being phased out but it can still be obtained if you know where to go.

You can spray acrylic lacquers over a cellulose basecoat if you make sure the base has sufficiently dried, usually overnight.

Stephen.

Thanks. I'll bear that in mind...

What about spraying cellulose paint onto an acrylic primer ??? Does the same apply?

Funnily enough, the acrylic primer and lacquer I bought in Halfords says on the tin that its fine to use with both cellulose and acrylic paint.....

As with most paints it is the solvent that will cause problems, not the paint itself, if you are careful you can bend the rules and get no after effects, given sufficient "flash Off" and drying time then yes you can apply cellulose directly over acrylic primer.

This will depend on the solvent, some are compatible, some are not.

I have painted cellulose directly over synthetic before today and this is definitely NOT recommended yet I got away with it due to rule bending even though the solvents were completely incompatible.

Stephen.

I didn't know that but then I haven't painted a car since 1967. I suppose it's because the solvents evaporate and then are an atmospheric pollutant?

I've a 73 MGB GT on which the paint is decidedly wanting, what preparation will I need to use one of these acrylic paints? What chance getting a colour match (Black Tulip BLVC23)?

Yep, its the high Volatile Organic Compound (VOC) which does the damage to the atmosphere, VOC was essentially a component required for the making of solvent paint types but recent paint development has produced low VOC paints which are typically water based which are becoming more commonplace. Cellulose is a high VOC so are some Acrylic paints however you can also purchase water based Acrylic so it can be a bit of a minefield when sourcing the right paint type.

I've found most paint factors can still supply cellulose as well as acrylic and twin-pack paint, it's probably best to ask at your local paint factor as to what paint setup they have which will determine what paint type they can mix in.

What preparation you require will depend on what's on the vehicle now, this could be any combination of Cellulose, Acrylic and possibly even twin-pack.

How old the existing paint is, you may be able to apply paint directly over an old original factory baked finish but not a previous re-spray.

What paint the present new paint mix is available in to determine any solvent incompatibilities.

Obtaining a colour match should be easy enough at any decent car paint mixing factor where they can alter the colour values to change a colours appearance to get an exact match.

Black Tulip (which is actually a red for those who don't know) is a standard straight non metallic colour still available in cellulose, your paint factor will know exactly what the available paint type is.

The British Leyland Vehicle Code (BLVC) 23 has been superseded to the newer Austin Rover Group (ARG.23) colour code, however your paint factor will also know this.

Stephen.

Thanks Steven.

Do I take it this would be my easiest route? If so I shall get some in stock. The car is original apart from a roof repair when a Belgian lorry driver forgot what side of the road to drive on, 6 months from new.

AJH

Sorry I should have said thanks Stephen!

AJH

Indeed yes, though it is actually listed as a RED.

If you intend to paint the whole vehicle you don't have to be fussy about colour matching, you can just simply order the paint online.

Stephen.

No prob, and I've been called worse things.

Stephen.
