I also use gloss medium when I want my artwork to have a bright, shiny finish. It gives my paintings a more polished look and helps colors appear deeper and more vibrant.

My Buying Guides on Gloss Medium For Acrylic Paint
What I Look For in a Gloss Medium
When I shop for a gloss medium for acrylic paint, I first check how well it enhances shine without changing the color too much. I want a medium that gives my work a smooth, professional finish and still keeps the paint easy to work with. I also pay attention to whether it increases transparency, because that matters when I want to build layers or create glazing effects.

- Glazing layers
- Increasing transparency
- Improving paint flow
- Creating a glossy top layer

Final Thoughts
In my experience, a good gloss medium can make a big difference in how acrylic paintings look and perform. I use it to improve shine, enhance color depth, and make my paint easier to handle. When I choose carefully, I get better results and a finish that feels more professional.
