Fineline™ Applicators Masking Fluid and Resist Fluid are one of our most popular products because it is so much better than the traditional method of applying masking fluid. Masking/Resist Fluid typically comes in a jar where you have to use your brush to apply the product. There are 2 problems with this method. 1. Because the masking fluid dries quickly, your product will degrade quickly when open. 2. The masking fluid can destroy your brushes if used for long periods of time. 

Fineline™ masking fluid is far superior to the traditional application due to the non-clogging cap-wire closure system. This allows for precise placement of the product without the mess, wastage, and clogging issues.  It flows beautifully out either the 18 gauge standard tip or the 20 gauge fine tip. You can also adjust how much masking/resist fluid comes out of the bottle depending on how hard you squeeze. Fineline™ Masking Fluid is also one of the only, if not only, liquid latex masking fluids that can be used safely by individuals who are allergic to natural latex rubber.

Depending on the type of effect that you are wanting to achieve, you may start with a white background, coloured, or pre-painted. Here are some steps to get you started.

Step 1: Choose your surface and make sure it is dry. (watercolour paper, cardstock, canvas, pottery, wood, glass, etc)

Step 2: Apply the masking fluid to where you want. Be sure to place the cap-wire back on when not using it. 

Step 3: Allow masking fluid to dry completely. The time it takes to dry depends on the weather and how much is applied. You can speed up the drying process if you place your work in the sun or use a hair dryer. 

Step 4: Apply the medium you want over the masking/resist fluid. Some suitable mediums include: watercolour, ink, dyes, ceramic glaze, acrylic paint (be sure the acrylic paint isn’t too thick over the masking fluid). 

Step 1, 2, and 3

Step 4

Step 5: Leave and let dry, keeping in mind the longer you leave it, the more difficult it is to remove. 

Step 6: (optional) You can keep adding masking fluid/paint to add layers and depth to your work.

Step 7: The moment has come to remove the masking fluid! With clean hands, simply apply a bit of pressure and rub off the masking fluid. Depending on the surface you are working on, you may want to use tweezers or use some dried extra masking fluid to help coax the masking fluid away from the surface.
