Holbein Sizing Liquid is an artist-grade sizing liquid used to reduce the absorbency of paper. Dilute it with warm water and apply it with a broad brush.

Priming with these products transforms supports not usually used for watercolor, such as canvas, painting boards, and wood, into suitable grounds for watercolor painting. Available in coarse and fine textures.

Susan Scheewe Wax Resist Sticks are a versatile tool for watercolor artists who want to retain the background color (or underpainting details) of a watercolor painting. They also are ideal for creating shapes or patterns, and for adding special effects such as sunlight, water, texture — even words.

Apply the medium directly to paper and allow it to dry before painting. The preparation then allows dry washes, including staining colors, to be more easily lifted from paper with a wet brush. Ideal for making corrections.
