Will Acrylic Texture Medium Crack on Unstretched Canvas?
If you want to work with different mediums to create different textures on a canvas, it’s fine until you have to roll them, as they can easily crack and spoil the overall design of your painting.
You might have to roll your canvas for shipping or storing, and so the texture medium you decide on, when working with the canvas, is essential to avoid this kind of damage.
There are a number of textures that can be used for different overall effects on the canvas, and these include pastes and gels.
When you start working with a canvas, you must ensure it is stretched as much as it can be so that it is incredibly taut within its frame to avoid cracking the texture medium later.
Different pastes are chosen because of the movements they leave on the canvas, as well as their ability to help prevent cracking once dried. These include modeling paste, which is a great favorite, as it can make magnificent peaks and troughs on the canvas, which creates an impressive design, and fibre paste, which makes a washy watercolor effect when painted.
Gels are thinner and can include string and absorbent ground, which is more of a paper-thin effect, which usually needs more than one layer and can build up a beautiful tooth on your canvas.
Heavy gel gloss is used as well to give peaks – it’s a great texture to work with because it’s so flexible and is a good medium to finish off with before using the acrylic paints on the canvas.
Let the canvas dry with the different textures over 24 hours, then lightly paint and allow to dry again.
Basically, you use these different textures in various layers to create the desired effect. You want for your canvas.
Between layering the different pastes or gels for the raised texture and letting them dry, you can paint the acrylic paints, powders, and glazes on to create the background color.
Allow time for drying in between each texture and paint application.
So try and ensure you:
Always work on a rigid, totally stretched surface
Use mediums with a flexible ability and do your own tests – your producing pieces of artwork which may need to endure the test of time, including different temperatures as well as being rolled and stored.
It’s a great idea to experiment with different mediums that you like – professional products are expensive but are far more endurable.
Therefore to ensure you only have cracks in your canvas where and if you want them, it’s a good idea to get used to the different textural mediums out there, before you work on a masterpiece.

STEP-BY-STEP PAINTING CLASSES
Questions and answers for using acrylic texture mediums:
1. What happens to a canvas if external, environmental factors such as temperature, aren’t taken into consideration?
Answer: Light, heat, and moisture can have a seriously detrimental effect on canvases which can cause the painting to crack, especially if shipped or rolled or not stored properly.
2. Once you have stretched your canvas, what should you treat the canvas’ surface with before acrylic paint is applied?
Answer: You should prime the raw surface of the canvas with titanium white, for example, as it seals the surface before you use different mediums to create texture.
3. What acrylic textures can you use on roll and ship or a raw canvas?
Answer – Modelling paste is popular if you are happy to have tiny cracks because as it has a rigid structure – if the canvas has been well stretched, it can take modeling paste as the paste can withhold cracks, which can add to the texture and overall effect.
Extra heavy gel - anything with gel in the title is going to be a more flexible structure, which is less likely to crack if the canvas is going to be shipped. Opaque and white – more plastic in its look, but this is a great medium to use.
4. Why is it not recommended to use a brush when laying down the acrylic textured mediums on your canvas, and what should you use?
Answer: You should avoid using a brush, especially a fine brush, as it can shed its fibers when layering the canvas with different texture mediums and instead use a palette knife. This is because the thickness of the pastes and gels used can help create various textures with a knife.
5. What should you use to create washy, watercolor effects on your canvas with mediums for acrylic painting and texture?
Answer: For a thin layer of absorbency, you should use layers of fiber paste – let it dry and then apply paint.
