Paper Stretching - Jackson's

Paper stretching is the process of soaking and securing watercolour paper so it stays flat while wet media is applied. This technique is essential for preventing warping, buckling, or cockling. It is important when using water-heavy techniques.

Artists typically use a board for stretching paper, gummed tape or paper stretchers, and a sponge to wet the surface. Once dry, the result is a perfectly taut surface that allows paint to flow evenly and predictably.

Stretching watercolour paper helps artists maintain a smooth, professional surface throughout the painting process. For work involving washes, gradients, or repeated layering, stretching ensures even results and prevents frustration caused by buckled or uneven areas.

‘Most watercolour painters have experienced the frustration of their paper buckling, causing the paint to flow everywhere except where they want it to go. Stretching watercolour paper makes it stay flat for the whole painting process.

The experience of painting on watercolour paper that stays perfectly taut and flat is a revelation to painters who have always fought with their paper.’

What are the Different Methods for Stretching Paper?

You can stretch watercolour paper using a wet method (soaking and securing it to a board with gummed tape) or a dry method with a paper stretcher. Tools like a sponge and boards are essential for each approach.

Can I Stretch Both Hot-pressed and Cold-pressed Watercolour Paper?

Yes, both types of watercolour paper can be stretched. The process is the same, but hot-press paper dries more quickly and may require more careful handling during the soaking phase.

How Long Should I Soak Paper if Using the Board and Water Method?

Soaking time depends on the weight of your paper. Lighter paper (under 200gsm) needs about 3-5 minutes, while heavier paper (300gsm and above) may need 10-15 minutes. Soaking expands the fibres and helps the paper dry flat when secured.

Is It Always Necessary to Stretch Paper?

Not always. Heavier paper (above 300gsm) is less prone to warping and might not require stretching. However, for artists working with large areas of water or on bigger formats, stretching watercolour paper remains a valuable preparation step.

A watercolour block is a pad of paper glued on all four sides, which keeps the paper taut while you paint, negating the need to stretch paper.
