Stone effect paints – Paints that look like other materials

Stone effect paints

Today we talk about post production, and more precisely of stone effect paints and other special paints.
When we think of post producing a printed object with a spray paint, we always think about the usual solutions. An antique silver, a gold paint, maybe a copper color. I liked it right away when I saw this stone-effect paint as a spray can, but my amazement is also increased when I found many other stone-effect colors available on Amazon.
And so I got the urge to try them on some scrap prints, to see their actual potential. I did not choose these 7 prints, I took them among my scraps, so they are not the best solution based on color, just a solution.

Obviously, this stone-effect paint is not only suitable for 3D printing, but for any kind of decoration. We could make an old plastic vase valuable, or use it to restore a wall, or any other application that you might think of.

Preparation for the laying of the stone paint

Before spraying the stone paint objects should be treated with a flat primer. I opted for a white primer. Depending on the effect of the stone paint you want to get you can also change the color of the primer, to make it darker (black) or give it a colored reflection (red, yellow, blue, green, etc.).

Selection of objects and colors

Here is the selection of objects on which we try the stone effect paintings:

Objects to paint.

Once decided I tried to match each object a color, and here are the combinations chosen with the color of the cap as an example:

At this point only the last step is missing, the painting.


Beyond the particular indications that I will give when we will talk about the specific colors, I can tell you that these stone paints seem to be composed of a transparent base with “pieces” of colors necessary to give the stone effect.
The job was not easy (I’m a beginner of painting). Unfortunately when I noticed a few more empty points and approached the bottle for a targeted addition the force of the spray moved the solid components of the paint and went to form a kind of crater.

So I suggest you try to pass several times on the same point trying to spray from a distance trying not to create voids.

Stone effect paints: Grey Alpine granite

Grey Alpine granite

This grey marble effect is one of the best colors tried. It is a grey matrix with small solid parts in dark grey, black, white and cream.
This set of colors makes the object realistic, rough to the touch. The matrix, a gray not too clear facilitates the overlap of the effect. So you can also use other colors as background, in addition to white.

How to paint. Stay at a certain distance from the thing you want to color, and try to make wide and slow movements, to make sure that everything is evenly distributed.

It is not necessary to give more than 2 times since the colored matrix, as already mentioned, is very thick.

Rating: 8. Easy to lay, great stone effect, what more could you want?

In this case a beige matrix with solid black and white inserts. If you scroll a little above and take a look at the cap of the color used, which should be an example of how the object should come you will realize immediately that there is something wrong.

In fact, the background white remains well present, despite having given 3 times. This means that the beige base does not exist as a color matrix, which is transparent, but only as a component, perhaps to a greater extent black and white.

Probably you can reach the effect of the cap after many times with this paint, and in the case of 3D prints distorting their details. On the other hand the effect is discreet also in this case. So usable but with some precautions. For example use as background the color we want represents the matrix of our stone!

How to paint. Stay at a certain distance, and try to make wide and slow movements, so that everything is evenly distributed. Use the background color we want to be the base of the stone.

Rating: 6. You get only a sufficient result without particular care.

Stone effect paints: black granite

What is this crap? You may be wondering… yes..
This particular vase has been ruined by this paint. The color is very thick and virtually zeroes out any detail. Moreover, it is not covering and to get a black uniform you have to give many times. This paint is probably suitable for colouring walls, fireplaces or other large geometric objects without details.

Little satisfied by this spray can that simulates black granite.

How to paint. I’m probably not the right person to explain to you how to use this material. I must have missed a few steps!

Rating: 4.  Although probably most of the responsibility is mine, for not understanding this material… surely has the fault of not being easy…and not for everyone. If you are skilled painters do not be discouraged, try it and comment with your successes!

Stone effect paints: Classic granite

How about this stone paint? Clearly different result from the previous one. Paint not overly covering, it took 3 hands, but exciting result! This corset, seen live, has all the air of being a granite object. The only flaw, it is rough to the touch and opaque to the view. Probably not by all this is considered a defect, and perhaps a further coat with a glossy transparent finish would be adequate.

How to paint. To use this paint stay at a certain distance, and try to make wide and slow movements, to make sure that everything is evenly distributed. It will take 3 times for the object to take the desired color without erasing too much details with a too thick pass.

Rating: 7. Amazing result however you have to work on it a little!

Stone effect paints: Granite

Granite vase.

Very similar to the classic granite, this granite differs for having a lighter matrix. We pass from the light grey of the classic granite to the white (very light grey) of this one. Very nice because, perhaps thanks to its colors, it perfectly simulates the granite. We distinguish “crystals” (here stains of color) black (miche), transparent (quartz) and white (plagioclase) immersed in a very clear matrix.

The resulting defect, however, is the poor coverage, to make disappear the yellowish of which the vase was made that was not completely covered by the primer I had to give it four times. Perhaps the peculiar figure chosen did not help, with all those ravines where the paint, especially this with many solid components is hard to get in.

How to paint. To use this marbled varnish stay at a certain distance, and try to make large and slow movements, depending on the background color may need more hands.

Rating: 6,5. Amazing effect, but too many times!

Stone effect paints: Marble

Marble effect.

From this image you can already understand that this marbled paint is not suitable for 3D printing. Certainly the model chosen was not one of the most appropriate choices for stone effect paintings. Especially because of the shape with recesses that do not suit the method used by this can.

The principle is based on randomly throwing a “drawstring” of black paint. This method could also work on large spaces, such as walls, or other rather large objects. Definitely not suitable for small 3D prints.

How to paint. To use this marbled varnish you have to stand far away, and make a very fast movement, both with your arm and with your finger, to spray little color at a time. If applied to really large objects, with fast and wide movements, maybe a series of movements in the same direction could really give the desired effect. Just be careful that it is sprayed a lot of paint each time, not a veil as you can think by squaring the cap of the same.

Rating: 4. Probably this marbled paint with a little practice might work, but it’s not suitable for home 3D prints.

Stone effect paints: Desert sand

I have to be honest, of all the stone-effect spray cans tried this is my favorite. First of all because by painting you understand that it has a unique consistency, in which the matrix and the solid parts, of the same color blend perfectly.

During the painting if you exaggerate leaving somewhere a drip that gives us the impression of staying shiny, this is completely reabsorbed by drying! And it gives us a fantastic sandstone effect!

Very satisfied with the effect of this paint!

How to paint. Stay at a certain distance from the object, and, through wide and slow movements, give several passes. Do not worry if in some point you leave more paint, drying will lose the glossy patina that this sand painting of the desert leaves at first. It is not necessary to give more than 2 times as the sand-colored matrix is very covering.

Rating: 9. The best. Easy to lay out, and a truly realistic effect!
