🧴 What It Is

Kiln wash (or shelf primer) is a protective barrier applied to kiln shelves and furniture to prevent glass, glaze, or other materials from sticking during firing.

🛠️ How to Prepare and Apply

• Mix the dry compound with water to a creamy consistency, like pancake batter.
• Use a hack brush (wide, firm bristles) for smooth coverage.
• Apply to the top surface of kiln shelves only.

🔁 Coating Strategy

Apply 8 thin, even coats for optimal protection and durability. Vary the strokes to help fill gaps and avoid streaking:

| Coat # | Brush Direction | |--------|--------------------------| | 1 | Right to Left | | 2 | Bottom to Top | | 3 | Diagonally (↘️) | | 4 | Left to Right | | 5 | Top to Bottom | | 6 | Diagonally (↙️) | | 7 | Crosshatch pattern | | 8 | Final smoothing stroke |

🔄 Maintenance Tips

• Reapply kiln wash frequently, especially after glaze drips or glass fusing.
• Scrape off any stuck glass and recoat immediately.
• Store leftover wash in an airtight container—it can be rehydrated.
