Available 157026 80-400-4 H20 Masking Liquid, 1 Quart, Clear, 32 Fl Oz (Pack of 1)

I'm using this product in conjunction with my cheap laser engraver and sand blaster. It works best on metal. I paint the liquid mask onto metal, then cut out a design from the mask with my laser engraver and then hit the part with my sandblaster and aluminum oxide blasting media. It does a nice job. I can get good looking results. The mask holds up long enough to get nice, even, frosted looking sand blasted designs. The mask doesn't hold up long enough to do deep relief blasting though. But that's asking alot. The mask then pulls off the surface easily. I know other people do the same thing with smooth, coated wood. I haven't experimented with wood or plastic much yet.

Absolutely LOVE this product. 10/10 such a time saver

I seldom write reviews, but I'm such a big fan of this product that I had to.I had to paint both sides of two doors and a clean paint job is very important to me. Each door had 10 glass panes, so I was looking at masking 40 panes of glass across both doors to get the straight lines that I wanted. That sounded beyond tedious with painters tape, so I went looking for alternatives and found this masking liquid.Applying the product was easy. After light sanding of the existing paint, I wiped it down and then applied 2 coats of the masking liquid around the edge of each pane using a cheap paint brush. I tried a single coat as a test, but found that it didn't remove as easily as I had hoped. The second coat of masking liquid completely resolved that.The masking remained on the windows for 2-3 weeks as I worked through primer and multiple coats of paint. When the project was completed, I set about removing the masking and couldn't be more pleased with the end result. The paint lines around the glass are completely straight and the masking removed easily from each pane in one piece. It did leave a slight residue on the glass, but that was removed easily with glass cleaner.In the end, this product saved time, provided great results and was significantly easier to apply than painters tape. Highly recommended!

The media could not be loaded. It works better if you do two coats or more. I only did one coat and it was a little hard to remove but not too bad. See video

I used this to paint three very large (at least 8ft tall) glass paned doors. Each door has 12 glass panes. It took me about 30 minutes to apply it to all of the glass. I used a Wooster paint brush from Home Depot to apply it. Dries to the touch in 30 min and ready to paint your surface in 2-3 hours. I used a Sherwin Williams latex paint for my surface. Once my paint was dry, I used a metal butter knife from my kitchen to score the film and peel it off. Worked great! Took some practice to get a feel for how much pressure to apply to the knife. But, it’s a really easy and effective product. It’s also very low odor.Oh, and I spilled over half of it on my engineered hardwood floors, but it all came off. I used towels and a mop with warm soapy water and it came up easily.

The media could not be loaded. Will never use this again. I have these windows with a LOT of panes. I thought the masking liquid would be quicker and easier than taping every window. Now, yes, application was much quicker but taking this crap off is the most tedious thing I have ever done. I followed the directions exactly. Used a razor to cut around the edge. Problem is, this product is like a stretchy latex, so the razor just kind of skips along and doesn't cut cleanly. So if you can see from the pictures and video, it leaves these little pieces of stretchy glue stuff that won't peel off in a strip. It would have been quicker for me to paint this window with no masking at all and scrape the paint after. Never again. Excuse me while I go pull off a million pieces of latex off my window for the rest of the night.

This stuff works great saves a lot of time , cheaper than tape and masking paper it's the cats meow love this stuff. Well buy again

I had heard so many people rave about this product. We have been remodeling our late 1800s farmhouse for what seems like forever. I am finally doing the interior doors and am now working on 2 which are glass paned.I have been painting everything and my skills are getting super on point. This includes what tools, brushes, sheens, and prep items I need or love or hate. I wanted an easy way to paint this door and not fiddle with the glass panes, so I figured I would give this product a go.It was a breeze to paint on it dried super fast. I was super jazzed about that. I cleaned, prepped, and primed the door and didn't worry too much about the panes, as this was on them. I did my few coats and tonight I began to remove the mask.I was so disappointed. It was tough to remove, was super sticky, and left residue. Now...did it keep the paint off the glass? Absolutely!! But the clean up was tough and it required me using a very sharp utility knife to work through. Sadly, I ended up slicing the wood in a couple spots, which i can hide, but still bummed me out.I think I would use it for less visual items, such as an exterior window or a window on an upper floor, etc. I have to do the other side of the door tomorrow and I am going to use painters tape and just be careful. I know the clean up will be a bit more involved, but I wasn't impressed enough with this product to use it again.All in all, it did what it said it would do, which was keep paint off the glass. But, for me, it wasn't worth the aftercare.If you do use it, I hope it goes better for you.
