Exclusive to Assembly Apparel
At Assembly Apparel, quality isn’t just a goal — it’s a guarantee. That’s why every custom shirt we make is sealed with our exclusive DeepSet Finishing Spray™, a proprietary formula developed in-house.
What is DeepSet Finishing Spray™?
DeepSet Finishing Spray™ is a custom-blended finishing solution used on all our apparel after heat pressing. Designed to lock in color, soften the feel of the DTF, and help your prints last longer, this spray plays an essential role in how we deliver long-lasting and comfortable prints.
HOW IT WORKS
After your shirt is heat-pressed, we apply DeepSet Finishing Spray™ while the fabric is still warm.
This helps the formula bond directly into the fabric, allowing the ink or transfer to set deeper into the fibers.
It also reduces any shine or press box marks that can show up after pressing.
The spray softens the texture of the print area, giving it a smoother, more finished feel.
Finally, it helps seal the design so it lasts longer and holds up better through repeated washes.
It’s a simple finishing step, but it makes a big difference in the quality, comfort, and durability of every shirt we make.
Non-Toxic & Safe
We understand that you care about what touches your skin. That’s why DeepSet Finishing Spray™ is

Skin-safe
Free of harsh chemicals
There are no fancy chemicals in our mix — just simple, safe ingredients you can feel good about. In fact, every ingredient in our spray can be found at your local supermarket. It’s a straightforward solution that gets the job done — no gimmicks, no nonsense.
