Q. How can I prevent cracks in my paintings? Any suggestions?
A. Acrylic paintings can crack for many different reasons.
The following is a list of the 3 most common reasons as to why this could happen:
Option 1: Regular VS Flexible Modelling Paste
If the cracks are a result of using a product like Liquitex Modelling Paste, check your label: Does the label read Modelling Paste or Flexible Modelling Paste?
If you are using Modelling Paste you will get cracks. If you are using Flexible Modelling Paste you will not get cracks.
Regular Modelling Paste was meant for a hard surface. Like wood for example. Once you put it on a flexible stretched canvas, the movement of the canvas causes cracks.
Option 2: Modelling Paste VS Plaster
If the cracks are a result of using plaster, please read this previous blog post: Modelling Paste VS Plaster.
Option 3: Temperature
Heat - Using a hairdryer to speed the drying process can cause the acrylic paint and medium to crack. I suggest that you allow the painting to air dry.
Cold - When the temperature dips bellow zero, I suggest not leaving your paintings in a garage or in your car. This can also cause cracking and it may even cause the texture medium to crack and fall right off.
