Does Tempera Paint Crack – The Quick Answer:
To prevent tempera paintings from cracking, avoid using too much water when mixing the paint and allow each layer to dry completely before applying the next one. Store your paintings in a cool, dry place away from direct sunlight or extreme heat or cold. Use high-quality pigments and eggs when preparing your own tempera paints and handle them gently when transporting or displaying them.
What causes tempera paint to crack?
Tempera paint is a water-based paint that is made with pigment, egg yolk, and water. One of the primary causes of cracking in tempera paintings is the use of too much water when mixing the paint. When excess water is added to the mixture, it can weaken the bond between the pigment and egg yolk, causing the paint to crack as it dries.
Another cause of cracking in tempera paintings is applying multiple layers of paint without allowing each layer to dry completely before applying the next one. As each layer dries, it shrinks slightly, which can cause cracks to form if there are multiple layers applied on top of each other.
Additionally, environmental factors such as humidity and temperature changes can also contribute to cracking in tempera paintings. Exposure to direct sunlight or extreme heat or cold can cause the surface of the painting to expand or contract, leading to cracks forming over time.
Possible Causes:
- Excess water
- Multiple layers without drying completely
- Environmental factors (humidity/temperature)
Is it common for tempera paint to crack over time?
Yes, it is relatively common for tempera paintings to develop cracks over time. This process occurs due to natural aging and environmental factors such as humidity and temperature changes. However, proper storage and care can significantly reduce the likelihood of cracking occurring.
In some cases, using lower-quality materials may also increase the likelihood of cracking. It’s important to use high-quality pigments and eggs when preparing your own tempera paints and store them in a cool, dry place when not in use.
Factors:
- Natural aging
- Environmental factors (humidity/temperature)
- Lower-quality materials
How can I prevent my tempera paintings from cracking?
There are several steps you can take to prevent your tempera paintings from cracking over time. Here are some suggestions:
- Mix your paint with the right amount of water to ensure a strong bond between the pigment and egg yolk. Too much water can weaken this bond, leading to cracking as the paint dries.
- Avoid applying multiple layers of paint without allowing each layer to dry completely first. This will reduce the likelihood of cracks forming as each layer dries and shrinks slightly.
- Store your paintings in a cool, dry place to minimize exposure to humidity and temperature changes that can cause the surface of the painting to expand or contract.
- Use high-quality pigments and eggs when preparing your own paints to ensure that they are strong and durable.
Are there any specific types of surfaces that are more prone to cracking with tempera paint?
Tempera paint can be used on a wide range of surfaces, including paper, canvas, wood, and even stone. However, some surfaces may be more prone to cracking than others.
For example, if you’re using thin paper or cardboard as a surface for your tempera painting, it may be more susceptible to damage from environmental factors such as humidity or temperature changes.
On the other hand, thicker surfaces like canvas or wood may be less likely to crack due to their sturdier nature. It’s important to consider the qualities of different surfaces before choosing one for your painting and taking proper care during storage.
Susceptible Surfaces:
- Thin paper/cardboard
Less Susceptible Surfaces:
- Thick canvas/wood
Can temperature changes affect the likelihood of tempera paint cracking?
Yes, temperature changes can impact the likelihood of tempera paint cracking. Extreme temperatures can cause the surface of the painting to expand or contract, leading to cracks forming over time.
To prevent this from happening, it’s important to store your paintings in a cool, dry place away from direct sunlight and sources of heat or cold. This will help minimize exposure to temperature changes and reduce the risk of cracks developing over time.
Prevention:
- Store paintings in a cool, dry place
Does the age or quality of the paint impact its tendency to crack?
Yes, both the age and quality of the paint can impact its tendency to crack over time. Lower-quality paints may be more susceptible to cracking due to weaker bonds between pigment and egg yolk. Additionally, if you’re using older paints that have been stored improperly, they may have started to deteriorate, making them more likely to crack or flake.
To prevent this from happening, it’s important to use high-quality pigments and eggs when preparing your own paints and store them properly in a cool, dry place when not in use.
Factors:
- Age
- Quality
How can I repair a cracked tempera painting without damaging it further?
Repairing a cracked tempera painting requires careful handling and attention to detail. Here are some steps you can follow:
- Clean the painting with a soft brush or cloth to remove any loose debris or dust.
- If necessary, use a small amount of water mixed with egg yolk to fill in any cracks or gaps in the painting.
- Gently press down on the surface of the painting to ensure that the egg yolk mixture has bonded with the existing paint.
- Allow the painting to dry completely before handling or displaying it again.
It’s important to use caution when repairing a cracked tempera painting, as applying too much pressure or using harsh chemicals can cause further damage.
Steps:
- Clean

In conclusion, tempera paint has a tendency to crack when applied on certain surfaces or if it is not handled properly. However, with proper preparation and technique, the cracking can be minimized or avoided altogether.
Frequently Asked Questions about Does Tempera Paint Crack
How do you make tempera paint not crack?
To slow down and regulate the drying process of your painting without causing cracks, place it in a box with an opening at the bottom to allow air flow. Although it requires additional space, the likelihood of the painting cracking under the box is minimal.
What are the disadvantages of tempera paint?
One major drawback of using tempera paint is that it requires applying thin layers, which can be time-consuming. Additionally, it is often unable to achieve the rich color saturation that is possible with oil painting.
How durable is tempera paint?
Tempera paint, also called poster board paint, is ideal for art and craft projects due to its quick drying, durable, and easy-to-clean properties. It is unlikely to flake, streak, or crack, and is water-soluble. Additionally, the majority of tempera paint available is safe and non-toxic.
Is tempera long lasting?
Tempera paintings are known for their durability, with some surviving from as early as the first century AD. Egg tempera was the dominant painting method until the 1500s, when it was replaced by oil painting.
Is there a way to make tempera paint permanent?
Tempera paint is not intended to be long-lasting and resistant to light like acrylic and oil paints, but it can remain visible on paper and similar surfaces for about a year, though its colors may begin to fade. To prevent this, you can apply a fixative to the painting.
Can I seal tempera paint?
Despite the water-soluble nature of tempera paint, it is possible to make it water-resistant on canvas by applying a waterproofing or weather-proofing substance. A sturdy primer is necessary for this process, followed by sealing the paint with a specialized solution once the painting is complete. This will provide an extra layer of protection against water damage.
