Concrete texture - is my guess correct?


Needle-chuck Ninja
I'm aware of the neat technique used for creating water droplets using solvent base paints and sprayed water:
to get this result:

What I would like to know is how this concrete effect is done:

Is this just the reversal of the droplet technique? e.g a dark pigment is sprayed across water droplets covering them 90% and then a small ridge is created by spraying a white in a counter direction to the darks.

It's a beguiling effect and I'm curious to know how it's achieved.
There are a few ways to do it. What Andre said is a good start. You can also speckle the paint on then highlight the edges.
Looks like the grunge spray with the fine tip to me, unfortunately it is not available in the uk. But there's more than one way to skin a cat. A combo of speckling and either making or using a stencil, or finding some other material to spray through, and then highlighting one side would give the same effect, although is going to be more work, it's do-able.
The way I would do that texture is with an FX texture stencile then highlight the edge to get the depth of the holes
Thanks people. I looked at some videos of the grunge spray (is it glorified carpet mousse?!) and one in particular looked close to this concrete effect. What perhaps isn't apparent in my photograph is that the highlighted ridges appear around every crater no matter how small. To paint each individual highlight would take a very long time indeed which is why I thought it (the highlight) might be achieved by directional spraying similar to the water droplets. I'll try and find another pic in extreme close up to show what I mean.

p.s It's out of stock Squishy but apparently you can buy it here:
I think there's no need to buy any kind of something "very special". That foam you can get from cans for internal cleaning of cars. I have one made in the US:) Sorry, I haven't posted a picture.
The volume of the can is slightly bigger than "magical" fx can. The only difference, you'd have to search for spray heads as can for cleaning comes with one type of spray head, but it's possible to find and to use another head from other cans, certainly it that head fits your can. Having different heads you can experiment with the pattern it produces. Besides, you can make custom made head, I don't think there's something special there.
I also tried shaving foam. But again, you need to have another spray head, as in the case of shaving foam you just can not have any spraying at all, those using shaving foam know what I mean. I've sprayed this foam onto white paper and being removed after drying it leaves nothing on the surface. At least I've seen and felt nothing. So, you could experiment with it also.
It would be great from someone having Grunge FX can to put here photo of the ingredients of the can (shown on the backside). I could take a picture of my can and we could compare the ingredients of both cans to find out if there's any difference. I've paid for the cleaning can some kind ridiculous price compared to "original" fx can. I mean I've paid that price locally, so I think for people from the US it could cost even less, not saying the price for "fx" spray is not something I'd pay for, especially if you experimenting for yourself. One thing if client pays for it, another if you do.
Mind, that foams do not work with waterbased paints.
Highlights should be done by using scratching and erasing techniques, it's much faster and effective than using an airbrush for it. You will not have any colour shift and if the highlight is too bright, you can always dull it using your dark colour.
Thanks @C0y0te. Last time I asked they said they couldn't ship outside the US because of regulations with pressurised containers. But £25 is too steep for me when there's other (albeit) slower methods.

Mike Levalle uses it a lot on his live feeds, and he always gets asked about putting different nozzles on different products, and usually replies "try it, see what happens, then come and get the real deal" or something along those lines. Personally I don't think its the foam but the nozzle that's the difference.

If you're doing a paying job you can add the £25 to the cost, and will save time, apart from that doesn't seem worth it.
Paying 25 pounds sounds even more inspiring than paying 16 bucks for a can:) Certainly, if it concerns my wallet;)

I've taken some pictures and hope someone using grunge fx cans will take pictures for ingredients.

The pattern it can create. I've done some sprays without any training or smth. The pattern is achieved using can's original nozzle.

Some description.


Ingredients. As you can see it will work for us as grease remover besides effects it can give.

And the can itself.

As you can see, the volumes of the cans are 15 and 18 Oz (425 and 510 g). For this can I've paid (locally) 7 or 8 bucks, so it's not that much for my wallet, especially I've bought it for the experimenting.
It's possible to get original Grunge FX from the US, not an issue for me. But the price for cans and the shipping does not make any sense for me to buy them now as I haven't got any income from custom painting yet. Maybe in future I'd buy if the foam I have here will not give me the results I expect. I'll definitely experiment with those cans I have. I'm pretty sure the results are not expected to be useless.
