Q. What does the PVA Glue label colours mean, e.g. Red, Blue & Black?
A. Hi B Johnson, thank you for your question. Red label is a junior version of Brian Clegg Black Premium PVA Medium, exhibiting some of its characteristics but with advantage of being fully washable when dry. PVA Blue Label is developed for younger children and specifically formulated to wash extremely easily from clothes, brushes, work areas and hair, even when dry. Black Label is a high quality craft and painting medium. Its flexible qualities and crystal clear finish when dry makes it ideal for mixing with paints without loss of colour intensity.
