Watercolour paper that has been kept for too long can have deteriorated sizing, and damage the paper to affect how paint and water behaves. <\/p>\n

Sizing for watercolour paper does not refer to the physical paper size, but to the substance that’s applied to the paper to affect paper absorbency. Paper without sizing applied will just have water soak through. Sizing is what turns paper into watercolour paper.<\/p>\n

Traditional sizing uses gelatin, but nowadays there are also plant-based, synthetic sizing or vegan-friendly sizing are available. Sizing can be done internally, externally or both.<\/p>\n

The most important thing to know is sizing can deteriorate when exposed to humidity<\/b>. In other words, try not to stock up on watercolour paper when you know you don’t paint often, or you can’t use up watercolour paper that fast.<\/p>\n


When the sizing deteriorates, paint would just sink and not move, and this make it difficult to paint. The paper will also create ugly texture, as shown above, and more examples here<\/a>.<\/p>\n

Restoring the sizing<\/h3>\n

There are products that can add sizing back to watercolour paper, such as the Daniel Smith Watercolor Ground<\/a>, but they will not be able to restore the paper back to original quality. <\/p>\n
