To use Thinner for brush-on acrylics effectively, follow these steps:

How to Use Micro-Mark Thinner (Brush-On):

1. Start with a Small Amount
• Pour a small amount of the thinner into a mixing palette or separate cup.
• Never thin directly in the original paint bottle—this preserves shelf life and consistency.
2. Mix with Acrylic Paint
• Use a brush, stir stick, or pipette to combine 1–2 drops of thinner per brush-load of paint.
• Adjust the ratio based on how thin or fluid you want the paint to be.
• For base coats: ~10% thinner
• For washes or glazes: ~30–50% thinner
3. Test Before Applying
• Always test the thinned paint on a scrap or hidden area first.
• You’re looking for smooth flow without pigment separation or excessive transparency.
4. Apply with a Brush
• Use a fine or medium brush depending on the detail level.
• The thinner helps paint flow into crevices and over textured surfaces evenly.
• You'll notice reduced brush marks and improved blending.
5. Clean-Up
• Clean brushes with water right after use.
• If paint starts to dry on your brush, dip it in thinner briefly to loosen.

Tips for Best Results:

• Don't over-thin or you'll lose coverage and adhesion.
• Use a wet palette to keep thinned paint workable longer.
• Ideal for layering, edge highlights, or hand-applied washes.

This thinner is also available in an 8 oz size bottle at Micro-Mark Brush-on Thinner.
