Dr. Ph. Martin's FRSK10OZLVL1 Martin's Frisket Mask Liquid (Level 1) Masking Fluid, 1.0 oz, Clear, 1 Bottle

The quality of this product is very high. It’s easy to apply, dries quickly and provides an excellent barrier. It’s easy to remove when dry. Really happy with my purchase.

I enjoyed using this! It’s stinky but does the job 👍 I used it sparingly and at first I thought it wasn’t going to work but even the super thin little bits sealed the paper perfectly ! I just used my finger , rolled it off and viola , done 👍

This mask liquid works well. It's great to protect areas when watercolor painting. My only complaint is that sometimes when it's being peeled off, it tears the paper. Usually this is only minor and can be covered, but it's definitely ruined a couple pictures when it tore off huge sections. Just be careful when peeling it off!

Works like it should. Only problem if using on water color paper it can tend to tear paper by lifting layers. Also use a junk brush to help spread because if you only use the dropper you will use too much product. The way to get the masking fluid off your brush afterward is use a product called goof off and a throw away cup ... just put the junk brush in the cup then spray or drip the goof off over the bristles where the masking is glumed up on and it will instantly remove the goopy masking. If you don’t use apply goof off or goo be gone then just throw away the brush. It runs out rather quickly. Use for a short duration because the longer it’s on the paper the more it adhears and it’s hard to remove.

I'll definitely be using it on my watercolor pieces and maybe even my marker pieces just to stay in the lines better. I did make the mistake of using a good brush though and will not make that mistake again😅

The stuff itself works great. Only issue was the dropper didn't work right off the bat.

I’ve used various friskets over the years. This one masks an picks up well. However, despite keeping the bottle tightly shut, it hardened into a messy, unusable blob within a couple weeks. I tried diluting it with distilled water, but no luck. I’m going to continue shopping for a viable frisket. This isn’t it. Shame, as I like the Dr. Martin’s line in general.

I've been very happy with this masking fluid. I've used it along side of several different types of inks and watercolors on both hot and cold pressed papers. I've not experienced any issues with bleedthrough or leeching under the masking fluid. I've been able to leave the masking fluid on paper, and thankfully the fluid does not cause any tears once it has dried and is removed, even after extended periods of time.
