SUSIE'S REPLY: Thanks for your question Carrie! There are several good liquid friskets aka masking fluids on the market today that won't harm your paper when removed. It is important to remember that masking fluids or liquid friskets should not be left on the paper for an extended period of time. Your type of watercolor paper needs some careful consideration too. Some watercolor paper's surfaces are softer and will not hold up to the wear and tear masking sometimes requires.
In my classes I use several masking fluids when painting my greeting cards. Each type serves a different purpose. These are all available online or in local art supply stores.
Pebeo Drawing Gum is a gray color which makes it easy to see when applying. It has a very thin consistency which helps to make some fine lines. Contains latex.
Daniel Smith Masking Fluid is milky in the bottle and dries clear to amber in color. This makes it easy to see and helps to determine the values when painting over it with darker paints. This manufacturer advertises that it can remain on the paper for a month or more after application. I find this to be true. Contains latex.
Incredible White Mask is a high-quality, non-pigmented liquid frisket is ideal for watercolor masking. It dries to a neutral cream color that shows through dry paint, so that you can see exactly where you've masked. Slightly thicker in consistency. Contains latex.
Winsor / Newton Colorless Art Masking Fluid a removable colorless liquid specifically designed for soft sized papers to avoid staining. Contains latex. Wash brushes immediately after use.
Blick Liquid Frisket Tinted orange color makes it easy to see. Works best on sized paper, and should not be used on wet paper. Remove the frisket by peeling or rubbing with a soft eraser. Ideally, it should be removed within 24 to 48 hours to achieve the best results. Contains latex.
Masquepen Art Masking Fluid The pale blue water-based latex solution is easy to see, apply, and peels away from paper without harm. Easy to see when wet or dry. It comes in a squeeze bottle with a needle tip making application simple and effortless. Contains latex.
Molotow Grafx Art Masking Liquid Pump Markers these ready-to-use, refillable markers contain a water-repellant masking fluid that applies cleanly and rubs off easily, leaving no residue. Molotow's patented pump delivery system assures precise, mess-free application and sharp edges. Latex free. A must for the plein air painter! An empty marker is also available to fill with other masking fluids.

Masking Fluids prevent
the paper from absorbing color. Use a watercolor mask before you apply a
wash to protect areas that you want to remain white. Peel away the mask
when it is no longer needed.
Most masking fluids use natural latex or a synthetic compound with very similar characteristics. Some may contain an artificial colorant so that you can easily identify the areas you have masked.
