It is advisable to use extra gum arabic when painting in layers with Winsor & Newton Designers Gouache. Make up a mixture of 10% gum and water and use this for thinning the colours. Use more gum arabic with any colours which smudge when dry care must be taken not to use too much or the colours will take on an uneven gloss.
