How to make sublimation spray for cotton?

Do you want to sublimate your 100% cotton clothes, shirts, socks, or pillow covers?

The bad news is that you cannot sublimate 100% cotton items.

The good news is that you can apply a polyester coating to cotton and sublimate it easily.

The polyester spray is required for polyester coating on cotton.

Here is how you can prepare polyester sublimation spray:

Required materials 

A spray bottle (8 or 16 fluid ounces), polyacrylic clear matte, and a tablespoon

Total time required

Depending on your speed and the materials available, it can take 5-10 minutes.


Here is a step-by-step guide on how to make sublimation spray for cotton:

  • Measure the polyacrylic: For every 8 fluid ounces of water, you will need 2 tablespoons of polyacrylic.
  • Pour the polyacrylic into the spray bottle: Use a tablespoon to measure out the correct amount of polyacrylic, making sure it is level.
  • Fill the spray bottle with cold water: Once the polyacrylic is in the bottle, fill it up with cold water.
  • Shake the bottle: Shake the bottle well to mix the polyacrylic and water together.
  • Spray the solution on the cotton item: Spray the solution on the cotton item.

Once the spray has dried, you can transfer the design to the cotton item by printing the design onto the sublimation paper. The colors usually fade on the transfer paper. Once you apply heat through a sublimation heat press or an oven, the colors will be as vibrant as on a 65% polyester item.
