Saunders Waterford 638gsm Watercolour Paper – 100% Cotton, Extra Heavyweight, 55x76cm (Pack of 10 Sheets)

Experience the ultimate in watercolour paper performance with Saunders Waterford 638gsm – an extra heavyweight, 100% cotton paper made by St Cuthberts Mill using traditional cylinder mould techniques. Endorsed by the Royal Watercolour Society, this luxurious paper is designed for artists who demand maximum strength, absorbency, and archival integrity.

At 638gsm (300lb), this is the heaviest grade in the Saunders Waterford range, eliminating the need to pre-stretch. It withstands the most aggressive techniques — heavy washes, repeated lifting, scrubbing, and layering — while maintaining surface integrity and shape.

Made from 100% cotton, and gelatine-sized both internally and externally, it delivers excellent surface strength and paint flow. The paper is acid-free, pH-neutral, and calcium carbonate buffered to ensure museum-quality longevity and resistance to environmental damage.
