Coverage
Approx. 40 m² at one 6-micron coat.
Additional coats can be applied wet-on-wet to build thickness and increase durability, with coverage decreasing as more layers are added.
Recommended usage is about 12.5 ml/m² per layer.
Apply one even layer by wipe application, or spray additional coats wet-on-wet with an HVLP gun.
Let it cure fully.
Important Prep Notes
Apply only to a clean, fully dry surface. Keep relative humidity below 70% during application. Full cure takes about 5 days. Once fully cured, the coating can only be removed by sanding.
