Lighter weight papers (300g/m² and lighter) may benefit from soaking and stretching to avoid the paper cockling (buckling) when applying washes.
Avoid exposing the paper to detergents, as these will affect the paper’s absorbency. The paper’s surface is most vulnerable when wet, and should be handled with care.
Masking Fluid shouldn’t be left on the paper for too long, it becomes harder to remove the longer it’s left, making it impossible to remove without damaging the paper’s surface. Bockingford does not have gelatine surface sizing, so isn’t as robust for masking fluid use.
Understanding the 3 surfaces or textures of watercolour paper
Rough – A pronounced, varied texture, great for a textured loose feel.
Cold-pressed (NOT) – It’s the paper texture in-between rough and hot-pressed paper, having a slightly textured surface this paper is sometimes called NOT.
Hot-pressed (HP) – Watercolour paper with a very smooth surface and almost no tooth. Good for painting detailed paintings and creating very smooth washes.
The Not stands for “Not Hot pressed”
