Mont Marte Masking Fluid Premium 120ml (4.06 US fl.oz), Masking Fluid for Watercolor Painting, Keeps Areas Free of Color And Edges Crisp, Resists Watercolor, Ink and Pouring Paint

This Masking Fluid is great. A little odor, as with all of them, but it works just like it's supposed to.

Ii was quite happy with this item and would purchase it again

Easy to apply and peel off. But if I apply over a painted area it peels off the paint too. May be it’s normal I just didn’t know about it. But really good for price.

This product is easy to apply with a paint brush (suggest working a dab of dish soap into brush prior to avoid the masking fluid to clump and stick in brush). Removes easily (make sre paper is dry)

Quality is very good- easy to apply , dries in about 3-5 minutes! Love this grout restorer pen!

The best way to use this is to go to a dollar store and buy super cheap children’s paint brushes, that way each time you use a brush you can just throw it away. If you let it dry on the bristles, you can use it again to get very fine lines in the painting.It’s important to make sure the lid is on tightly after use otherwise a skin will form across the fluid.The bottle may look small, but it lasts very long time and it was a very good value.

It’s ok to use, just don’t forget to use a crappie brush because it does ruin them if very time. It goes on clumpy and has an annoying smell, but aside from those issues, it does the job.

I am now learning about the masking fluid. It will block off a section of your watercolor painting. It will prevent the colors not to bleed together. It smells awful but the masking fluid does an excellent job with blocking off any watercolor bleeding.
