Using this specific product

Before you start

- For clay pottery, pay particular attention to the exact variant, preparation and environmental conditions.
- At manufacturer-stated conditions; temperature, humidity and film thickness can change drying time.
How to check readiness
Check the real material or treated area at the slowest location before the next step. Confirm the surface is dry and ready before continuing. Lift or move the item gently and avoid twisting the bond or pressing finished faces together. Allow 24 hours or complete firing/cooling before paint, glaze or finish.
