Custom-mixed paint colours
« on: March 03, 2017, 07:29:45 PM »

 Hi all,

Does anyone know where I can get acrylic paint (suitable for models) custom mixed to specific colours?


I know the British Standard colours I need for my model boat and found several companies on-line that custom mix aerosol paints to any colour, in any finish from high gloss to matt and in paint types of Cellulose, Acrylic or Synthetic Enamel, so I ordered my paints from www.cjaerosols.com in Satin Acrylic.


Most were ordered as aerosols but I got the green for the decks in a 500ml tin so that I could use a brush to paint those hard to get to places as the build progresses.


When I opened the tin, I was beaten back by the smell of solvent which I later found even melts the plastic (styrene) that most my model boat is built of (except the hull which is fibreglass). I can get around that by first applying a couple of coats of primer, but the paint is quite thick and starts to dry in seconds. I’ve experimented with thinning it with cellulose thinners but it’s still not great and it's difficult to avoid brushmarks. If I end up buying an airbrush, I suspect this paint may also be too thick.


It seems in this case, “acrylic” doesn’t mean "water-based"! Can any of you offer advice or suggest where I can get the right type of paint mixed to order?


Thanks in advance.


PS: My model is of the 1970’s cross channel ferry “Free Enterprise V” from an excellent kit supplied by www.linkspanmodels.co.uk
If you’re interested, I’m documenting the build on Facebook. Just search for “JP’s model boats”.

Right then....try halfords for starters but you really need to know what the car colour that is closest....ANY motor factor that sells Automotive car paints should be able to mix you the correct colour.....Troll through Ebay and there are plenty of shops on there who can mix coulours for you ...if you can't get anything then Pm me and I can get them done  for you.

Thanks Stavros,

It's not getting the right colour that's the problem, it's getting the right type of paint in the right colour... The paint I bought is automotive paint, just like you can get in Halfords or any motor factor, but these paints seem to be solvent-based and quite thick whereas model builders acrylic paints such as those from Humbrol and Tamiya are water based and easier to work with.

Th point being is that any car based aerosol is a lot thicker than the watery type that are Humbrol and Tamya paints....Paint from car aerosols can be as thick or thin as you want......simply build up the layers Slowly thats what you need to do....As I don't use Humbrol or Tamya paints then someone else might be able to help as I don't know where you ca get them in the Water based paint,maybee you need to buy yourself and air brush and spray them on that way...Who knows,Maybee someone on here knows where you can get some Water based aerosols from...Sorry I cant be of help

Thanks Dave

I guess I was on the right track then by just thinning the paint down. I think I might just buy myself an airbrush and learn to use that in a very fine spray instead of using a brush.

Cheers,

Hi John

I've decided to do it in the original early '70s pale green Townsend livery for now and maybe in time, if I get bored with it I may repaint it, first in Townsend Thoresen orange and eventually even in P&O blue...

In that case you real need to plan and map out your paint plan .By this I mean . Take each livery work out what you need. Eg for TT orange ,Red oxide . TT orange ,White deck green ,pale funnel green .
Work out what is available in each colour ,eg acrylic ,enamel ,car paints etc . You should real stick to one type of paint to avoid reactions .
Car sprays are great but a paint to paint in corners on a deck. On Celestine I found a car paint green and a Humbroil acrylic that are all most the same shade so I can touch up.
You have to be so care full with diffrent paints to avoid reactions


John
PS speak to Carl as I think he knows were to get TT orange . I will need some next year

If using car paints like Halfords then you can just spray some into the can cap and use a brush to touch in any unsprayed areas, it blends in very well and is also useful for covering up unintended blemishes.

You can do that . But spray paint does not like to be brushed . I is very hard to get a good finish . And a car touch up pen in the same shade is even worse . Been there done that .

It's OK John, I already have all of the right British Standard colour codes for the model. When I built my first ferry model "Super Viking" back in 1978, I wrote to Townsend Thoresen to find out the correct paint colours! Let me know when you need them and I'll send you the list.

I've hear about the issues with mixing different types of paints which is why I'd like to stick with one type, but I'm a stickler for accuracy and the only paints I can get to the exact colour are automotive paints, hence this post. It looks like I'm going to have to stick with this type of paint and get used to it.

I've not had any problems with doing that but you do have to have a very delicate touch, the idea is to 'lay' the paint on the surface in a single pass. If you try to brush it out then the solvent can interact with the existing finish and produce drag marks. As with many things, it's just a question of technique.

Colin, John

This was the very point of my post... I can get any colour I like mixed to order in solvent-based automotive acrylic paint, but it doesn't like to be brushed on, certainly not neat... you have to thin it first and it's a pig to work with as it starts to dry in seconds and tends to leave brush strokes.

I guess you're right Colin, it's a matter of technique. I've only just started doing this, so I guess I'll get the knack of it eventually.

Certainly being able to get the paint made to order in any colour is a great advantage, so I think I'll stick with this type of paint and just learn to use it as best I can...

if you were to go down the route of enamel for the whole lot then you can get them custom made . You can air brush enamel paints but I am not  a fan of them . Much prefer acrylic paints . If you want me to I can ask Mike at Howes were they get there paints done and how much .

Being able to wash brushes in water is the obvious advantage of acrylics as I see it, but I'd be interested to know why you prefer acrylic to enamel and what you feel are the pros and cons, John.

I'd certainly be interested to know where you can get enamels mixed to order, but if anyone reading this knows where you can get acrylics mixed to order that would be good.

If you are overcoating/overlapping existing paint then one of those cheap flat nylon artists brushes can be very good. Spray the paint into the can cap and it will be quite runny. Dip the brush in and just kiss the surface once with it when you apply the paint. Don't put too much on. If it doesn't quite cover then have another go but only when it has dried. The technique is only really good for small areas but it does usually work.

I have never been very good at painting myself but with age comes patience and that seems to be the key to it! (plus don't try to mix different types of paint - the results are unpredictable!)

good old google and i found the supplier that they use to do the Railmatch paint in the enamel range.
https://www.hmgpaint.com/


You have found the main one . cleaning is so much easier .  differently with an airbrush
I fine acrylic dries a lot quicker than enamel so in an evening I can get two coats on a fitting if I use acrylic.
On Celestine i had to do the orange hi zis above the bridge . to say humbroil enamel is crap is an understatment. Some people may love them far play . Me wont touch them . Have a look on the net there enough comments about the over price chines poor paint that Humbrol sells

I think Humbrol paints are now manufactured in the UK again following the quality control problems when they were outsourced to China but there may still be stocks of the Chinese stuff around.

Just touching base here......  Hi JP - onto the painting stage already eh?  These types of ship can be a beggar to paint and I have been giving a lot of thought as to the sequence of painting the Norland lately as that is a job that is rushing over the horizon.
 
For the prototype Free Enterprise, we used regular Halfords automotive paint off the shelf - red oxide below the waterline and Fiat 'Capri Blue' for the P&O colour.  Halfords white primer for the white superstructures seemed to go on well.  The decks were Humbrol enamels painted by hand with a GOOD flat artist's brush (much less masking needed that way). 
 
Just read the 'small print' on the Halfords can I have here (the blue) and it says it is 'an advanced acrylic based formulation'.....but it clearly uses a solvent as the 'carrying medium' to carry the paint from the can to the surface and then this solvent evaporates off leaving the paint dry. (STAVROS - I guess that is what the solvent is for???).  It expressly says to use thinners to clean the nozzle...... So I don't think it is water-based at all.
 
The whole model was then covered in a sprayed coat of satin varnish.

Thanks for your input Carl.... Painting the hull and superstructure is a long way off yet and I've already got the spray paints for that from cjaerosols.com.
My immediate requirement is to paint the enclosed and "hard to get to" deck spaces that will be too difficult or even impossible to do once the model is completed. Some bits of this can only be done with a paintbrush.

Even if I spray paint the decks before fitting them, there will be some touching up to do wherever I've used glue or filler or done some sanding. The solvent-based automotive spray paint I have is not well suited to being applied with a brush, so here's my dilemma: Should I...
  • Spray decks in advance with my automotive paint to get a good overall finish, then use the same paint with a brush (despite it being very difficult) to touch-up the glued/filled/sanded joins. If I go down this route, would the painted surface still be adequate for glueing the superstructure/bulkheads onto?

    or should I...
  • Paint the decks with a brush using either enamel or acrylic and then spray with satin varnish later, as you did. I think the closest Humbrol colour is#3 Brunswick Green (please confirm), but that's only available in gloss and I want a satin finish. So if go down this route, is it OK to spray satin varnish over gloss paint? Perhaps I could lightly sand the gloss finish to flatten it and get rid of brush stroked before spraying on satin varnish...
What do you thoughts on this? Perhaps it's worth me trying some of these ideas on a sample off-cut of styrene sheet and then decide...

Carl white primer is ok for prep work but has a low pigment . I would go for Halfords appliance white . High pigment and a very white finish
