A hot fix rhinestone AB coating is a type of decorative embellishment used in various craft and fashion projects. The term "AB" stands for Aurora Borealis, which refers to the iridescent coating applied to the rhinestone. The AB coating creates a beautiful shimmering effect, reflecting different colors when exposed to light.

To apply hot fix rhinestones with AB coating, you will need the following:

1. Hot fix rhinestones with AB coating: These are available in various sizes and shapes. Make sure they have a heat-activated adhesive on the back.

2. Hot fix applicator or heat press: This tool is specially designed to apply heat and pressure to activate the adhesive on the rhinestones.

3. Heat-resistant surface: Place your project on a heat-resistant surface to protect it from damage during the application process.

Here's how you can apply hot fix rhinestones with AB coating:

1. Prepare your project: Make sure the surface you are applying the rhinestones to is clean and free from any dirt or oils. This will ensure a strong bond between the rhinestones and the surface.

2. Arrange the rhinestones: Plan out your design by arranging the rhinestones on your project. This will give you an idea of how they will look before applying them permanently.

3. Heat up the applicator: If you are using a hot fix applicator, plug it in and allow it to heat up according to the manufacturer's instructions. The applicator will usually have different heat settings for different types of rhinestones.

4. Apply the rhinestones: Once the applicator is heated, place a rhinestone on the desired spot. Press the applicator firmly against the rhinestone for a few seconds, allowing the heat to activate the adhesive. Repeat this process for each rhinestone, making sure to leave a small gap between them for proper adhesion.

5. Let it cool: After applying all the rhinestones, allow your project to cool down completely. This will ensure that the adhesive sets properly and the rhinestones stay in place.

Remember to follow the instructions provided by the manufacturer of the hot fix applicator and the rhinestones for the best results. Additionally, it's a good idea to practice on a scrap piece of fabric or material before applying the rhinestones to your final project.
