Making Acrylic Paint Crackle

How To Make Acrylic Paint Crackle?

Cracking is defined as a surface line or cracks along which something has split without separating into distinct pieces.

Paintings can be made to have a crackle appearance, which is a beautiful and enjoyable method to play with acrylic paint. You can express yourself more fully through various media.

The ideal tool for giving your painted surface an aged appearance is crackle media. Simply apply acrylic paint to the surface first, and then cover it with the crackling medium. Before applying sealer or further layers, wait for the crackling paint to cure completely.

If you don’t give the crackle medium enough time to dry, the underlay will not fracture. By adding additional layers of crackling medium, you can make the cracks larger or keep them small by only using a thin layer.

Crackle media is an indispensable tool for any daring painter or artisan since it gives your painted surface a patinated or grainy appearance.

How Can A Cracked Acrylic Painting Be Repaired?

There are different approaches to restoring damaged artwork:

  • Repainting after scraping or sanding
  • Filling
  • Letting it be

The ideal technique for your artwork may vary depending on what caused the cracking. Each technique has some subtle differences. Paintings made of acrylic often break for a variety of reasons.

It’s crucial to comprehend the origins of the cracking even if the techniques of scraping, repainting, and filling are suitable for the majority of causes of cracking. This assists us in determining the optimal repair technique as well as in preventing further breaking.

1 – Repainting After Scraping Or Sanding

Scraping, sanding off, and repainting a painting may sound overly dramatic, but occasionally, if you truly want to save this artwork (or merely the canvas), you should think about sanding off (or scraping) the cracked portions of the painting.

Sanding is your greatest option if you need to fix some minor, cracked areas in your painting.

Scraping is your best bet if you want to get rid of all of the cracked acrylic paint from the canvas so you can save it and paint it all over again. Sand or scrape our painting before repainting and varnishing it.

In addition to removing layers, sanding may also be used to make amazing effects and textures!

Sanding is not the same as simply filling a crack, so be careful of that! If you want to repaint or add a new coat, or if you see significant cracks, bubbles, or lumps.

2 – Letting It Be

All works of art are exquisite! It might even be advantageous if you pour or paint in marble, old-style, or abstract acrylic. You might always claim that you did it on purpose.

Also, keep in mind that many well-known paintings in art museums all around the world contain flaws that simply add to their appeal.

Try asking your friends about your painting without letting them know if it has any cracks if the “leaving it be” option irritates you. 80% of people will give you an honest assessment of your artwork, and the majority will say it is perfectly acceptable. Cracks will only be pointed out by you and nosy artists.

3 -Filling Cracks With Paint

Pouring cracks is the simplest method of acrylic painting repair and is excellent for both amateurs and professionals.

Instructions for patching flaws in acrylic paintings, in detail:

  • Make sure there is enough light and that the surface is clean. Use acrylic liquid paint. It would be ideal if you remembered exactly which paint you had previously applied to this area.
  • With your fingertips or a towel, rub the paint within each crack. The easiest way to apply paint is with your fingers since you can feel where to add additional paint and whether it needs to be thinned out right away.
  • Depending on the extent of the cracks, you can also fill them with paint using a paintbrush, a spoon, a child’s plastic medication syringe, or a zip-top bag with a little corner cut out. Because the paint will shrink as it dries, be sure to put just enough to cover the crack.
  • After rubbing or filling the crack as much as you can, wipe away any extra paint with a cloth and try to rub the paint in even further.
  • Check to determine if the fill was adequate once the paint has dried. You can go back if you think it wasn’t sufficient.
  • Be careful that if the fracture is deep, it may be difficult to completely cover it up, but the filling will significantly enhance the painting’s appearance.

The Causes Of Acrylic Paintings’ Cracking

Your acrylic paintings’ cracking problems are caused by a small number of extremely understandable and simple-to-avoid causes.

Acrylic pouring experiences cracking, but acrylic paint may also experience it. The main cause of cracking is that you apply too much paint to the canvas too rapidly, which interferes with the drying process. It’s crucial to remember that cracking frequently results from several elements acting together.

Inferior Paint

It’s true that occasionally you are more likely to assume that cracking results from inferior materials. It may very well be the case, but hold off on blaming your paints, especially if you are aware of their prior success.

Many forum users still rely on inexpensive paint to get good results.

Too Many Layers Or Too Much Paint

The likelihood of a canvas cracking increases with the amount of paint used. This is especially true if other elements, such as poor paint quality, are causing these changes to occur more frequently.

Poor Canvas

The most frequent canvas-related problem is improper stretching of the canvas, which causes cracks during the drying process.

Poor Timing

Due to variables, poor timing can result in cracks in acrylic paintings. Since the layers dry at various rates, there is not enough curing time between layers, especially dense layers.

How is the acrylic cracking effect created?

To use the crackling medium properly, layer it under the top coat of paint you want to crackle and let it cure for at least two hours. The media produces well-defined fissures and dries clear and glossy. You can create both thin and thick cracks depending on how much media you apply.

What causes the paint to crackle?

Bubbles are one of the causes of paint that are peeling or breaking. Paint has the ability to entirely fracture after it bubbles. Paint can bubble when moisture, heat, or both are present. Make sure the wall is absolutely dry and cold before applying the first coat of paint.


If applied sticky while painting, acrylic can be used to create a crackle effect on vinyl surfaces. To create this desired effect, a flat top coat made of latex or acrylic may be applied over the adhesive.

A single brushstroke will provide a better crackle effect than several ones, yet multiple strokes may completely eliminate it. Be aware of how your application may affect the final result; if acrylic is applied too thickly, it may become brittle and less flexible.
