How To Heat Set Acrylic Paint on Denim

But first, how do you know if it’s time to heat set your acrylic paint? There can be color transfer when using regular paints on clothing, especially dark colors like black or navy blue. This happens in any dye when one piece touches another and transfers some colors onto that item. Heat setting is a process where you let the paint and dye dry before touching the other clothes. This way, they don’t get more ink on them.

What you will need:

  • Disposable fabric
  • Iron
  • Acrylic paint

Step One – Preparing Your Surface:

Preparing Your Surface

The first step is preparing your item for painting by washing it with mild detergent and warm water. This allows the surface to have some texture to retain its shape better while being painted upon. If there are no instructions about washing your clothes, don’t wash them before you paint or dye them. This will make it more difficult for the paint or dye to stick. After drying completely, apply a thin layer of heat-set on the fabric.

Step Two – Heat Setting First Layer:

After applying a thin coat of heat-set, let it dry completely before painting your next layer onto the denim. This way, the paint will not smudge while being painted. You can use more vivid colors without worrying about the color transferring to other clothes or the color fading.

If you want your paint to dry quickly, wait at least 30 minutes. If not, the paint will take a few hours to completely dry. Sometimes two layers are needed for complete coverage, so wait until both layers are completed drying before moving forward with another one unless stated otherwise in your painting instructions.

Step Three – Finalize with More Layers:

After the paint has dried completely, you can add more layers of acrylic fabric paint onto your item to make it brighter or deeper. If you want a gradient look, use more than one color simultaneously. Wait for them to dry, and then heat set in between layers.

You may need up to three coats, depending on how deep you want the colors. After completing all your layers of colored acrylics, let it dry overnight before applying another coat of heat-set if needed. This will help seal in the colors even more so they don’t run while being washed. It is also an extra step that adds durability and ensures vibrant colors!

After your acrylic paint has dried completely, you can heat set the item again to make it even stronger. But how do you know when something is dry? Acrylic paints will be dry and ready for use if there is no raised sheen or sticky feel on top of it after about 30 minutes. If not, let it sit until this happens before using them again. Next, cut the paint with scissors to test how well a layer of paint is stuck onto an area. Cut into where the painted-on fabric meets nonpainted fabric without cutting too deep, so you don’t damage anything underneath! If none of your colors seep through, you are good to go and have a quality product!

Tips for heat on acrylic paint on denim:

# Use a baking tray or metal cookie sheet with raised edges. This prevents spills and keeps your work surface clean if you need to lay the fabric flat during painting, for instance, while doing more detailed design sections.

# The best temperature setting depends on how thickly you apply the paints to your materials. A higher temperature setting is required when using thicker applications of acrylic paint. If thin layers are used, lower temperatures can be sufficient for adhesion.

# Allow it sometime before moving them from their initial position after heating has been done because it will help the paint become more sturdy.

# You can use a heat press or iron with a medium to high-temperature setting for about 15 seconds after heating.

How do you heat-treat acrylic paint on jeans?
