How To Keep Canvas From Cracking

A common worry for both artists and art admirers is the eventual cracking of canvas paintings. This blog post aims to instruct you on how to prevent cracking, thus preserving the lasting beauty of your artwork.

What Causes Canvas to Crack?

The cracking in canvas artwork is primarily due to the drying out of oil paints, which can shrink over time and pull at the flexible canvas, causing cracks to form. This is particularly common in climates with low humidity or in artworks that are improperly stored or cared for.

Preventing Cracking in Your Canvas Artwork

1. Properly Prepare Your Canvas

The first step to crack-free canvas art involves properly preparing your canvas before you start painting. Priming your canvas with a quality gesso can create a smooth, non-absorbent surface that allows your paints to sit on top of the canvas rather than sinking into it.

2. Use High-Quality Materials

Quality matters when it comes to your art materials. High-quality paints and canvases are less likely to crack than their cheaper counterparts. While it might be tempting to save money on cheaper materials, this can often lead to cracking in the future.

3. Control Your Environment

Another significant way you can prevent cracking in your canvas artwork is by controlling the environment where your artwork is stored or displayed. Temperature and humidity can have a huge impact on the longevity of your canvas artwork. Try to keep your artwork in a place with consistent temperature and moderate humidity.

Code Snippet:

// Example of a simple humidity and temperature monitor using Arduino
#include <dht.h>;

#define DHTPIN 2     
#define DHTTYPE DHT22   


void setup() {

void loop() {
  float h = dht.readHumidity();
  float t = dht.readTemperature();

  if (isnan(h) || isnan(t)) {
    Serial.println("Failed to read from DHT sensor!");
  Serial.print("Humidity: "); 
  Serial.print(" %\t");
  Serial.print("Temperature: "); 
  Serial.println(" *C");

4. Proper Storage and Handling

The way you store your canvas artwork can greatly affect its lifespan. Avoid storing your artwork in direct sunlight, as this can cause the artwork to fade and crack over time. Instead, store your artwork in a cool, dry place where it won’t be exposed to the elements.


Preventing cracking in canvas artwork can be achieved through proper canvas preparation, the use of quality materials, controlling the environment, and proper storage and handling. By following these steps, you can ensure that your canvas artwork remains vibrant and crack-free for many years to come.
