• Apply evenly and allow the primer to dry completely — the colour will change from opaque blue to clear blue when dry.
• Drying time is typically 1–2 hours depending on surface and environmental conditions.
• Do not dilute the primer with water — use it as supplied.
• On very porous surfaces, a second coat may be required after the first coat has dried.
