How To Prevent Canvas Painting From Cracking

Are you an artist, art enthusiast, or someone who enjoys adorning their space with stunning canvas paintings? It can be disheartening to see cracks forming on your cherished works. But, with the proper understanding and methods, you can avoid this. This blog post provides guidance on preventing cracks on your canvas paintings.

Understanding Why Cracking Occurs

Before we delve into the solutions, it’s important to understand why cracking happens. Cracking, also known as crazing, commonly occurs due to factors such as the aging of the painting, inappropriate environmental conditions, poor quality materials, or improper techniques during the painting process.

How to Prevent Canvas Painting from Cracking

Here are some steps you can take to prevent cracking in your canvas paintings:

1. Use High-Quality Materials

Using high-quality materials is the first step in preventing cracks. The quality of the canvas, paint, and mediums used can significantly affect the longevity of your paintings. Cheap materials can result in cracking over time. On the other hand, investing in professional-grade materials can enhance the durability of your artwork.

2. Proper Painting Techniques

Proper technique is vital in preventing cracks on your canvas paintings. One important rule in painting is ‘fat over lean’, meaning each subsequent layer of paint should contain more oil than the previous one. This allows the upper layer to dry at a slower pace than the lower ones, reducing the likelihood of cracking.

3. Ideal Environmental Conditions

Extreme temperatures and humidity levels can cause your canvas paintings to dry out and crack. Maintaining a stable and appropriate environment for your art pieces is crucial. Ideally, the temperature should be between 60-70 degrees Fahrenheit, and the relative humidity should be between 40-60%.

4. Proper Storage and Handling

Ensure your canvases are stretched and primed correctly before you start painting. Avoid rolling the canvas too tightly for storage as this can result in cracking. When handling, always ensure your hands are clean and free of oils or creams that could potentially damage the paint.

5. Use a Protective Coating

Applying a protective coating or varnish can help protect your canvas paintings from dust, UV rays, and moisture, which can lead to cracking. However, ensure the painting is completely dry before applying the varnish.


Preventing canvas paintings from cracking involves careful attention to the materials used, the painting process, the environment, and handling. With these preventive measures, you can ensure that your artwork remains vibrant and crack-free for many years to come.
