Apply a thick, even coat using a medium pile roller, using a brush for edging. Load roller evenly and generously, ensuring paint is not spread across more than 0.5m2 per roller load. If areas have been missed during application, these may be touched up rather than overcoating the whole area as the paint will dry to match the original coat. Leave a minimum of 4 hours before touch up. Failure to apply correctly may result in a second coat being required, particularly if overpainting a darker colour with a lighter topcoat. Do not apply in very damp or humid conditions or in extreme temperatures.
