Hahnemühle Expression is a natural white paper for all wet painting techniques. It consists of 100% cloth - i.e., cotton fibers - and therefore belongs in the same league as particularly high-quality papers. On its glued surface, colors appear brilliantly; wet colors are absorbed only slowly. Therefore, for a short time, you can remove it and correct it again. The matte watercolor paper can withstand frequent erasing and its pick resistance ensures that paper fibers do not detach from the surface even when wet. You can remove masking media and scratch crepe without residues even after a long time. Its surface is matte, so only slightly irregular surface delicate representations and fine details come into their own. If you work wet-on-wet, the colors are radiantly even and more controlled than on rougher papers. The block is glued on all four sides so that its remains flat even when wet. But don't separate the painted sheet until the colors have completely dried.
