Crackling Textures – Methods and Results

A Review of methods of producing crackled texture effects in paintings.

  1. Crackle Paste – A Golden product that requires a rigid substrate and thick application. Doesn’t work on Yupo or paper. Somewhat chalky.
  2.  Kroma Crackle – from Kroma Industries. Relatively new product. Thinner application and can be used on flexible substrate. Takes a long time to dry–even in the winter time with humidity low in the studio.  It is somewhat fragile when it starts to dry.  Can easily be limited to smaller areas. Dries to a chalky white color, with the darker color underneath as the cracks. Then it can be painted on top as desired, with either watercolor or acrylic paint.

    Kroma Crackle – after completely dry. Cracks vary according to the thickness of the application. A few pieces of the dry compound have brushed off in handling.
  3. Crackle Glaze – made by Poly Vine Industries. Designed to be used with flat Latex paint. Gives interesting cracked effect.  And looks good, and probably can easily be localized as needed and still look natural.

    Surface after Crackle Glaze used. On the left hand two thirds it was painted with a very light blue latex interior paint. On the right I used gesso, tinted a bit with blue India ink.
  4. Stamping – totally repetitive and no control over size of crackles. The stamp I have has rather large spaces.
  5. Organic based spray paint over water wetted substrate. Can be on a flexible substrate, but very unstable and fragile till coated with fixative of some sort. I have used this in multiple paintings on Yupo with good, quite subtle results. Generally limited to small areas. Not predictable size of cracks.

    Black commercial spray paint (in pressurized cans) over a wet surface of reddish acrylic paint.
  6. Dirty Pour – simulates crackling a little bit in some areas, but totally unpredictable and very hard to control in all aspects.
  7. Hand painting … very tedious and almost impossible  to get looking natural.

Conclusion: come back next time, hopefully in a few days.  In the meantime, thanks for reading, and if you have any questions or additions please comment. The link is just under the title.

Problems With Dirty Pours

People have complained about the smell of using Silicone spray in doing their dirty pours.  The solution is two-fold: Use an already liquid silicone oil, or make your own oil.  I have a 2 oz. dropper bottle that I take outside and spray the silicone from the pressurized container into the  bottle.  This eliminates the odor of the spray itself when using it indoors. Then I can just add 5-8 drops of this silicone to each color cup with almost no odor.

Here’s the way it looks:

Notice the tip of the tubing is a little less than half way into the bottle. This allows the liquid silicone to run into the bottom of the bottle and the propellant to come out without loss of the oil. Also note that I’m spraying into the side of the bottle.

Have you found any other ways of dealing with the odor of the spray?  If so please say in the comments.  Thanks.

Using Water Soluble Embroidery Stabilizer

Getting just the right amount of visual texture in watermedia abstracts is sometimes difficult, and probably time consuming.  I, in my always quest for something new to use in my painting decided to try some embroidery stabilizer that my wife had.  Now, I buy it it larger rolls (she doesn’t use it much anymore)  since I really like the textures I get when using it, and it also is great for using over a previous painting that never made it to the finished pile.

Here’s the process in pictures–as well as text.

This is the painting I’m going to re-work, showing the roll of Hydro Melt embroidery water-soluble stabilizer. Notice my very finest brush that I use for doing this. The stabilizer cannot be torn, so must be cut with a scissors.
Here’s the painting with the watered Gesso and stabilizer over it. The amount of gesso can be adjusted before applying the film.
Bright hot sun speeds up drying which otherwise will take 24-36 hours.
This is after the first layer of a dark maroon watercolor paint has been applied. Notice how some of the color and previous texture show, in addition to all the new texture from the embroidery stabilizer.

So here are the steps:

  1. With perfectly dry hands, cut a piece of the stabilizer to fit the painting. If your fingers are the slightest bit damp they will stick to the film and tear it when you pull your finger away.
  2. Apply a moderately small amount of gesso to the painting and spread around with a generous amount of water. The amount you have on your paper will determine how much of the painting shows through.  I’ve found that I quite often add too much gesso, and have to blot some of it off before applying the film.
  3. Apply the film, being careful not to curl or crease it before putting it down–takes some practice, but is usually easy to do. If I’m doing it on a large piece, I usually have someone help me, to hold up the other side.
  4. Once it’s down in the gushy wet gesso, I usually add some more water to the top as I’m brushing out the wrinkles and air pockets.
  5. Dry it.  Doing it outside on a bright sunny day speeds up this process. Otherwise just leave overnight.

Things to remember after the stabilizer has dried:

1. When you add any water based paint on top the stabilizer will start to melt again, and it sort of makes a sticky gooey mess if you stay too long with too many brush strokes. It’s in and out quickly, and let it dry again before doing anything else. I like to add stamp  and template sprayed designs on top after an initial wash of watercolor.

2. It’s almost impossible to lift any color once it’s in there. When it is dry you can add something on top easily. This one got pretty dark, so I may have to add something on top to modify it.

I will leave the instructions end here, for completion at a next time. The last picture above awaits more development.  Try using the embroidery stabilizer to save a painting that you don’t like or hasn’t made it.  You’ll be surprised at what you can do with it.  If you do, let me know in the comments. I think you can upload an image there, too. (I’m not sure)  Anyway if not, you could e-mail it to me and I’ll add it to a further post.

Save your drips from pours

I did a swipe pour on a 20×16″ canvas. I didn’t keep it very level and a lot of the cells just ran off the side. Didn’t like the look of the canvas texture either.  I thought it might make a good background for a painting. Started adding things, first some straight lines, and then followed some of the lines in the original background with the same pen. Made a variety of lines, but it still didn’t seem to say anything. Went back to look at some of the freezer paper that had all the drippings/skins from previous pours, and found just the right colors. Since they were a couple weeks old, they peeled off the paper easily and I applied them directly to the background. They stick well when pressed down. Don’t leave them too long as they become permanently adherent.  So, now I’m not going to throw any papers away that have drips on them.

Here’s the result so far.  I’m going to add some more details to it with skins before it’s finished. I think it’ll be called High Wire Act.

Is Silicone Necessary?

A couple of people have asked me what does the silicone do, is it necessary?

The short answer is yes, for sure it’s needed, although sometimes you can get fair cells without it, by using alcohol instead of silicone.

How does it work?  I’m not sure, but I think it’s action is in rising to the surface through the layers of paint, causing them to layer on the outside of the silicone oil as it’s rising through the paint layers. It’s all based on the Specific gravity of the paints which goes where.

Here are two tiles, made from the same paint mixture–the first one didn’t have any silicone or alcohol added. The second had about 7-10 drops of silicone in each color.  I tried to add about the same amount of each paint.

No silicone added to any of the paint mixtures. Tan area are the tile showing through–possibly dirty (greasy) tile.
Same mixture of paint, with added 10 drops of silicone to each color before putting them together.

I hope this information has been useful to you. If you have anything to add or coment on please do so in the comments.

Demo at SWMWS meeting

At our regular October meeting of the Southwest Michigan Watercolor Society in Battle Creek this past Monday, the 1st of October,  I talked and gave a demo of acrylic pouring with media to dilute the acrylic paint and create cells using silicone. I used my usual Blick Acrylic fluid paints and PaintEasy. Also tried some old Lucas Acrylic paint that I had.  Some of it seemed to coagulate when I added RainX to it.  Did a couple of dirty pours and swipe pour. on a new material that Joanna Learner had brought–seems like a thick Yupo. Unfortunately it was not flat, so though the pour had great cells, a lot of them ran off afterwards.

Here’s the pics of the pours:

Swipe Pour-About 12×12. Notice how the cells are all run off all the sides. The few in the center have stayed the same.
This is the second pour I did–it’s on an 8″ tile and I was able to lay it perfectly flat. Will be interesting next month when we meet again what has happened to them.

 

Mini Pour Workshop

Yesterday was another workshop on Acrylic pouring techniques. We started in the morning with 8″ tiles. I did a quick demo using a previously used wood panel. Then I prepared full cups of five paints–white, black, red, yellow and blue.  Diluted them with water and PaintEasy, added some silicone, but ran out, so I used some RainX I had.

This is after it had dried some, but still has a long way to go. Can change a lot.

I did the pour on a sheet of Yupo  (26×20″ ) supported on a 3/4″ insulation board. Amazingly this stayed flat during the drying process. I put it out in the sun in the afternoon,  but didn’t have it perfectly level, so had a little running before it stabilized.  It is still beautiful, especially if you like bright saturated color. Later I tried a pour using some of the same colors   but added some metallic bronze as the predominant color, on a 1/2″ Foamcore board.  Remind me not to use them again.  Within a couple hours it wa shaped like a bowl and the metallic paint seemed to want to turn to mud. Boo hiss!!!!

Here’s a couple of the student pours.

One of Carrie’s pours. She did three others in the same color scheme.
One of Linda’s Pours
She used an unconventional approach. After failure of her first pour on this tile (mud), she poured some pure colors on top, and then heated it. What a nice tile she has–surprised us all.

 

 

The Soo Experience

Just got back from a great experience painting with Helga Flower.  (http://www.helgaflower.com/HFBiopage.html   and  https://www.facebook.com/helga.flower.9)

We played with pouring techniques. She had a piece of thick foamcore board 30×20″ and I decided to try a swipe pour.  Mixed up a about three hundred ml of red, yellow, black and white paint with PaintEasy, water and silicone.  Everything worked well, and I stabbed into the painting with the edge of a piece of Yupo I was using for the swipe.   Only problem that happened was the bending of the Foamcore from the wet media. All the beautiful cells in the lower part didn’t stick around. But, it’s still nice.  I’m thinking Yupo may be better for doing large pours because it doesn’t curl when  wet.

This is a piece about 9×12 of Yupo that we did a preliminary pour with. It did not curl at all, and didn’t loose any cells over the edge.

This picture was taken just after completing the pour.  I had to take it a quite an angle to prevent glaring from the overhead light.

The main star of the show was this piece–30×20″

Again, tremendous glare from the above light, so it’s a little distorted and  I got a dark spot (shadow) on the lower right.  Helga’s picture later is much better.  (She has it posted on her Facebook page.) Since this was on 1/2″ Foamcore board we didn’t think it would bow out, but it sure did, and it lost a lot of the cells on the bottom and in the red area.

We used a formula of 2 parts paint and water mix (the paint I was using was old and quite thick, so I diluted with water to normal fluid acrylic thickness),  and then mixed this two parts to one part of PaintEasy.  [Or approx 30% PaintEasy and 66%  fluid acrylic paint.]  PaintEasy is another product that is much thinner than Floetrol, so less water is needed for the final mixture.

Some other pictures from our Soo adventure are here (click on the picture below to see all the others.)

Thanks for looking.  Comment?

Pollination

Finished a smaller piece yesterday. Again, this one has had not quite nine lives. But, each layer I’ve added adds to the whole.  This one has had water soluble embroidery stabilizer applied over a couple of failed layers.  I really will take some pictures of that process and explain it in a future post. Just don’t have the proper documentation right now.

Here’s the piece–I’m calling it “Pollination.”  Some of the previous layers show through–only  if you know what those previous layers were.

Afternoon Pours

This afternoon I mixed a good amount of paint for pours. I used Dick Blick student grade fluid acrylics. They are quite old and were a little thicker than when purchased a couple years ago, so I mixed a little water in also.  I mixed all 5 paints the same way.
1. 60 cc. of paint
2. 30 cc. of PaintEasy
3. 4-5 cc of water as needed to thin it down to what I estimated the original viscosity of the paint was. I used, Titanium White, Ultramarine Blue, Magenta, Chrome Yellow (Probably a Cad Yellow-looks like it) and Mars Black.
4. Added 10-14 drops of Silicone. The silicone I use is from a spray that I spray in a larger bottle and then add to a dropper bottle. This technique keeps from getting all the chemicals in the spray indoors, as I can spray it in the bottle outside.

Here are some pictures of the pieces I did. First though my setup.

This shows my setup for the pours. The table in the distance is for collecting the completed pieces. It is very level.
This was my first pour today. White, yellow and red. Added a couple drops of red and black afterwards.
Swipe pour on a piece of hardboard that had been sealed with Gesso, and then i sanded the Gesso.
Was running out of white, so mostly yellow and black and some blue and a couple drops of red and white.
This was the last pour I did from that same mix of paint. Only had a few drops of white, lots of black and a little red and blue in the mix. This actually is an 8″ tile, but distorted because of the angle I had to take it to avoid reflections. I corrected it some, but didn’t want to loose any of it. I’ll get a better shot when it’s dry.
This is a shot of multiple drips from multiple pours this afternoon.

You can see from the last two that white is NOT necessary in every pour.  You can get cells without the white,  and I think they’re even better than with white.

Please add your comment or questions about my techniques.
