Daniel Smith Masking Fluid – 1 oz Online

This easy to use masking fluid comes with a fine point bottle applicator (extra tips included). Masking fluid makes an impervious barrier to protect your paper and preserve white areas of negative space by blocking watercolor from flowing into areas where you don t want it, leaving crisp, clean edges. Dries to a caramel color so you can see it – when it s dried and you are ready, rubs off just like rubber cement!
