Daniel Smith Watercolour Masking Fluid is easy to use with the bottle applicator, 5 applicator tips are included. Daniel Smith Masking Fluid makes an impervious barrier to protect your watercolour paper and preserve the white areas by blocking watercolour washes from flowing into areas you don't want leaving crisp, clean edges. Masking Fluid applies as an off-white colour and dries to a transparent caramel color so that you can see it while working, and still be unobtrusive while working on your painting. Easy to remove when Masking Fluid has dried with a rubber cement pick-up or even with your clean fingers. Be careful though, about leaving oils from your fingers when rubbing off the dried Masking Fluid, oils from your fingers can interfere with new applications of watercolour. Once the Masking Fluid had been removed, either keep the white areas white or add fresh watercolour onto the preserved white area to retain maximum watercolour luminosity.
- Don’t shake the Masking Fluid, that will cause air bubbles that will get into the applicator tip and transfer the bubbles into your Masking Fluid line. DANIEL SMITH Masking Fluid does not need shaking because latex mixture does not easily separate
- Keep Masking Fluid upside down in a small glass when working with the Masking Fluid in between actually applying it. That way if there are any bubbles, they remain at the top and don’t get into the applicator needles.
- Be sure to thoroughly rinse out the applicator tip immediately after using to prevent clogging when it dries. A good tip for rinsing out the applicator tip once you have a 2nd bottle of Masking Fluid: Is to save the empty bottle, rinse it out and fill with clean water, then place the just used applicator tip on the bottle applicator and flush out the liquid Masking Fluid by squeezing the bottle.
- You can also use a paint brush instead of the 5 tips that come with the Masking Fluid. Do not use your good brushes because all brushes will eventually get clogged up with dried Masking Fluid. Be sure to immediately rinse brush well with water.
- To remove Masking Fluid, use a Rubber Cement Pick-up rather than your fingers so you don’t soil or get oil from your fingers onto your watercolor paper.
