Pebeo Easy Peel Liquid Latex Masking Fluid - Drawing Gum - Dries Quickly - For Ink - Watercolor - Gouache Painting & Illustration - Fine Arts & Crafts Supplies - 45ml Bottle

I ran this through an ‘endurance’ test today. I used three different types of applicators - one was a ruling pencil (a very cheap one) and two were silicon ‘brushes’ (also cheap). Bottom line was this mask will be an indispensable part of my toolkit. Detail:I made thin lines with the ruling pencil and thick lines with the ruling pencil and with the silicon brushes, and swooshes with the silicon brushes. Ruling pens require frequent refilling but the mask didn’t seem to be more likely to bleed at the places where I had to refill my ruling pen. I did curves and straight lines. I did little dots and circles. Once the masking was done, I let the mask dry for about 90 minutes before applying in different areas water color, water color pencil, and colored pencil and mineral oil blender. Mineral oil in my test didn’t negatively impact the mask one bit.Bottom line is that this mask passed every test.I was happily surprised that the mask did alright with colored pencils. I was a bit careful in my pencil strokes though, because I think the pencil EVENTUALLY would remove at least the edges of the mask, but in my test it didn’t happen. Not even a rubbery nubby! I didn’t color a lot with pencil over the mask, but I wasn’t as careful as I could have been. Not one edge of the mask came up with the pencil work. That’s amazing. Let’s call my level of caution with the colored pencil ‘careless light’ (as opposed to ‘wantonly wild’ or ‘fearfully timid’). Light pencil pressure didn’t seem to mangle the mask in my test.I waited with mask removal until about five hours from mask application. The mask removed super easy with a rubber/gum eraser (also purchased on Amazon). In fact, once I started removing the mask with the rubber/gum eraser, I could pull off long pieces of the rest of the masked line without even using the rubber/gum eraser. This seems to be a strong mask if it turns into something strong enough to pull off in one piece!Even though I used lots of water in some of the watercolor, and mineral oil with the pencil, there was NO BLEEDING either above or below the masked lines. I purposely did one side yellow and the other blue just to see if I’d find any green - there was no green! I used so much water that the watercolor bulged up to the line, but no bleeding. That’s fantastic!Cleanup of the tools I used to apply the mask was pretty easy - and my application tools super cheap.I like the blue tint in the mask, makes it easier to work with. Also makes removing the mask a true ‘reveal’ - the difference is quite fun!Definite recommend. Enjoy!6-30-2022 UPDATE: I applied quite a bit of masking fluid using a ruling pen on one page of Canson XL Bristol paper. I estimate the masking when all added together covered roughly 40% of this 9”x 13” piece of Bristol paper. After the masking was all applied, I ran out of time and so did not add color (Caran d’Arch water color pencil and Prismacolor Premier color pencil) until the next day, so the mask was on the paper for more than 24 hours. It worked without any bleeding (either on top or below the masking fluid) and amazingly removed easily (with my fingers) without damaging the paper, and left absolutely no residue at all on the paper. I’m also surprised how much masking fluid is left in this little jar after this project! A++++ 5 stars :)Hope this is helpful info for you :)

I love this liquid frisket for preserving whites in my watercolor paintings. With a ruling pen, it's easy to apply and it lift easily when dry.

I’ve had bad luck with masking fluid in the past but this one worked beautifully! The smudge on the lower right was due to my impatience in waiting for that area to dry completely. As you can see, it did an excellent job of masking out the area that I applied the fluid to. The liquid was not dried out, the bottle was full, and it appears to be brand new and in perfect condition. Like any masking fluid, it does have a bit of a smell to it. I’m prone to migraines & it wasn’t an issue for me personally because it’s not strong unless you put your nose up to the bottle. There’s no residual smell once it’s applied. It was very easy to remove with the tool I bought here on Amazon, which I plan to review next. Hope this review is helpful. Happy painting!Edit: Two years later, my bottle is still in perfect condition. It never solidified on me. Don’t be afraid to try it, it works and is a quality product. I also love the blue coloring because it shows up so that I can see what areas I’ve applied it really well. It works as well on cheap paper as it does on Arches. Very happy with it & rebuying soon as my bottle is getting low.

Works well and didn’t rip up the watercolor paper I’ve used it on

The only masking fluid I use. It applies easily and comes off just as easily. The blue color makes it easy to see small places it might have been used.

It came off with an eraser but the thinner it was applied the harder it was to remove.

Worked great! I was able to mask subjects and water splashes and apply broad brush washes for water and sky.

Very easy to use! So happy with this purchase. The quality is great and the price is reasonable. Dries very quickly and it is easy to peel off.
