Rozcienczanie farby (akrylowa Tamiya)

Witajcie, Mam taki problem. Chce rozcienczyc farbke (czarna akrylowa Tamiya XF-1) tak aby lekko przyciemnic kawalek modelu.

1) jesli uzyje Tamiya Thinner to pomalowany obszar bêdzie lekko blyszczacy - bedzie sie wyrozniac od pozostalej, silnie matowej czesci modelu.

2) jesli uzyje Vallejo Matte Medium to powstala farba zostawia zbyt gruba warstwe - matowosc jest zachowana (namalowalem ciemnawy naciek i wyrazne 'wystaje' on ponad powierzchnie farby dookola)

Jakiego uzyc rozcienczalnika aby farba nie nabrala 'grubosci' ani nie stracila matowosci?

Hmm...

Mr. "Flat Man" is at it again. :-)

I'm not sure how much help you'll get here on r.m.s posting in Polish.

And I see that you are still worried about the elusive "flatness" of paint.

Why not just do all the painting you need on your model, then spray the entire model with a flat clear finish? That will assure that the entire model has the same "flatness" level.

Yep Sorry. I tried to cancel this message but I guess I failed. And you are right - I am getting Flat Base and I'm going to test it :)

ps. it's not that I want entire model flat - it starts flat than by touching, brushing I get areas more and less flat. But this can be done only if the starting 'flatness' is flat enough. I hope the flat base will allow this 'de-flatting' procedure :)

pps. See? I got some help from You :)

Maciek,

I hope you know that Flat Base is not a clear varnish - it is a flattening medium that you add to Tamiya glossy paints to make them flat. If you paint your models with Flat Base it will turn frosty white... If you want to make flat varnish from Tamiya paints, get their Clear and add a drop or two of Flat Base to it.

For some uncomprehensible reason some Polish hobby shops owners sell Flat Base as flat varnish...

Pozdrawiam, Pawel

Complicated :) Thank you - I will also get the Clear. I will also try to use this Flat Base as solvent for by Flat Black - maybe this will be enough for me. I won't need to repaint the model with Flat Clear if my diluted paints won't loose their flatness (like they do when diluted in Tamiya Thinner)

BTW - I have Flat Varnish from Vallejo - but I don't like the trouble with applying it - it has to be done with single brush strokes otherwise something strage happens to the surface. And I don't mean the trouble with humidity and low temperature - these are easy to avoid. But I had to repaint my Pz IV after treating it with this Flat Varnish. It's good only for small surfaces that cam be easily covered with a single brush stroke.

I'm glad that I was helpful!

You have to realize a basic fact (we are going back to your Flat Black thread) that glossy paint is smooth and flat paint gets its flatness from the its surface being rough (on a microscopic level).

When you rub the flat paint with something, you are polishing out the roughness and that makes it less flat (or smoother or glossier). Also, when you touch it with bare fingers, some oils from your fingers get absorbed into the rough surface of the flat paint. So again, it becomes less flat.

Some flat paints (but not most hobby paints) are quite hard. For example, paint which is used to paint inside surfaces of cameras or lens housings. But even that very flat paint can be scratched and it will also absorb oils from your fingers.

So, if you really need your paint flat, handle your model gently while wearing gloves and make sure not to rub the flat painted areas.

Or, you can still mask off the area you want flat and spray them with clear flat (Dullcote) when the model is almost finished. That way, you won't be handling it much, so it'll stay flat.
