    • Great Masking Fluid
Style: 2.5-oz Bottle Color: Art Masking Fluid
Goes on easily and rubs off just as well. Performs as expected, very nicely covering areas to remain white in watercolor painting. Dries quickly.

    • Awesome product!
Style: 2.5-oz Bottle Color: Art Masking Fluid
OMG! Love this product! I had previously bought a cheaper masking fluid that was in a squeeze bottle. Horrid on all types of paper. I tried this brand on cheap practice paper as well as good cotton paper. One was only left a few hours, and another overnight. Both removed with just rubbing with my finger. Didn't need an eraser. I do suggest buying the tool to apply. Better than gumming up a brush and works in small areas. ... show more

    • Works for me
Style: 2.5-oz Bottle Color: Art Masking Fluid
Works well for me. This is the only brand I’ve tried, and it masked well and was easy to remove. It has a yellowish tint which heels to show where you have placed it.

    • Great idea
Style: 2.5-oz Bottle Color: Art Masking Fluid
Awesome product. Still learning how to use it. Seems to dry fast, faster than I thought. The only thing is that it can pull some of the print off and tear the paper some. Otherwise, I really enjoy it.

I’ve used this masking fluid for years, and it has never let me down. Recently, I tried switching to a different brand but eventually went back to this one because it works perfectly for me. After drying, it doesn’t let water through, and I don’t have much trouble removing it. Just keep in mind that it has a strong smell, though not overwhelming. Here are some tips I’ve learned over time, if it helps anyone: - The best way to apply this or any masking fluid is with a silicone tip. It’s soft and allows you to spread the fluid evenly. Using brushes can damage their bristles, but if you choose to use one, select an old brush or one you don’t mind getting stained. Be sure to wash it immediately after applying the fluid to prevent it from drying on the bristles. - Since this masking fluid has a beige-yellowish tint, the longer you leave it on, the more it can stain the paper. - It can be removed relatively easily with your fingers or a curved tool that won’t damage the paper. Always be very careful, especially with 100% cotton paper, as it’s more delicate (and expensive!). It’s a good idea to test the masking fluid on a separate piece of paper before applying it to your final work. ... show more

    • yippee to this masking fluid for watercolor!
Style: 2.5-oz Bottle Color: Art Masking Fluid
I’ve never used masking fluid before, and it’s a game changer! Instead of trying my hardest to keep white areas clear of color, this covers areas while painting, to be peeled off after, and voila, beautiful white paper underneath without hassle. I use a small dotting tool to brush the fluid over the paper on areas I want to keep white. You can also use this product over dried watercolor painted areas to preserve while painting over it. overall recommended for artists, if you haven’t tried masking fluid yet, I suggest you give it a try ... show more
