157026 80-400-4 H20 Masking Liquid, 1 Quart, Clear

This stuff is great! Easy to apply and to remove. Just as advertised and makes the job so much easier!

This is an incredible product. It really deserves a 10 star - no lie. I bought it for a house we are flipping where the windows are brown from 1960's and we had to paint every window in the house with several coats of both KILZ and also paint. I needed a fast way to apply this product and get to painting so this is what I did to save time. I poored it in a plastic pan liner. I used a $2 rectangle shaped applicator from home depot that has a foam handle and has a soft bottom that is soft. I applied this product to each pane fast with a UP, LEFT DOWN, RIGHT, UP LEFT DOWN RIGHT 2 or 3 times around each panel not really making it perfect if it went on the wood a little. I did make sure I added too much not too little. Applying first coat and waited 45 minutes with fans on and applied a second coat - a HEAVY coat just heavy enough that it wouldn't run. I only applied the second coat to the outside border not to the center of the glass area so much. The next day I sprayed the glass and frame over the day with several coats and the day after it was time to remove. I cut with a razor blade box cutter a clean simple perfectly scored 4 lines on the outside edge so that when I pealed it off it would be exactly where I wanted it to peal and it worked perfectly. It is important to score the corners perfectly where you want it to peal away. NOT only does it work perfectly but it cleans the windows also which was huge perk for me as these were gross. Now, I had a not so brilliant idea to use elmers glue to see if it would work as well and let me tell you NO it does not work at all. We ended it scraping it all off the hard way and it was terribly stuck on the glass so take our lesson and do not try that ! I bought 2 quarts and it did the whole house, 2 heavy coats on all glass panels as explained above. Hope this helps others. This saved me SOOOOOO much time on this project and the finished perfectly cut lines made it look so nice when done. The extra that I did not worry about getting on the wood just painted perfectly and is not noticeable in the end.

I am not the best painter, but this product makes everyone that much better. My cousin told me about it. I used to tape and paint would always seep under making my windows look horrible. This time for my sidelights and transoms it came out perfect. It is easy to apply. You just paint it on your Windows and trim, let dry and then with a blade trace out the edges and peel. The can I thought was expensive, but you only use a little, so I can do do many more jobs in the future with it.

This works as intended and saved me a ton of time. I will say that it doesn't perform as well on previously painted edges. It's rubbery/siliconish in nature, and doesn't adhere well to those surfaces, so RE- painting can be more of a challenge than new paint. But it does do what it says and beats masking tape. I would probably only use it on masking intensive jobs like French doors. Otherwise, tape is just as quick and reliable. Would recommend.

great, made painting our window trim easy, it is harder to peel off in the cold, but scraping made it come off easy, in the heat it peeled off no problem

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!

Works great! I love this stuff. It’s so much faster than taping and there is no bleeding underneath like tape. Also I was able to get it to work on textured glass by using 2 coats. Well worth the cost, works on textured glass and extremely easy to use!

FROM A PAINTING CONTRACTOR: I spent a WHOLE DAY testing this product in MULTIPLE scenarios on my project and learned a LOT. Here's my results... 1. Using only one coat with one coat of paint over the top... did not work well. Came off in smaller strips. 2. Using 1 coat with two coats of paint over the top... worked a little better but really not great. 3. Using 2 coats with one coat of paint over the top... worked about the same as #2 above, maybe slightly better. 3. Using two coats of this plus two coats of paint... worked pretty decent, but NOT awesome... most came off in 1-2 pieces but still had to scrape a little around the edges. 4. Using THREE coats of this plus two coats of paint... worked quite well... most came off in 1 piece. Also tested it on... 5. Old (early 1900's) glass - worked ok but definitely needed full 3 coats 6. Newer glass (from 1980's) - worked better. 7. Dirty glass - seemed to stick a little to hard water spots on glass but altogether worked pretty well. 8. Clean glass - seemed to help it come off a "little" easier. SUMMARRY... This product ONLY works well when you use 2-3 coats of it PLUS two or more coats of paint OVER it. It DOES NOT work well if you use less than this. IMPORTANT NOTES: 1. IT WILL STICK to old paint on glass making it not come off too easy on those areas. 2. DO NOT let this stuff touch your wood or surfaces you want to paint on ANY EXTERIOR painting. It WILL NOT BOND and your paint job WILL PEEL OFF MUCH FASTER - ESPECIALLY on exteriors - like the next winter. 3. I learned this product is worthwhile ONLY if you TAPE the perimeter of the glass, then paint the centers, or... if you don't care about the quality of your exterior paint job and are ok with it peeling off soon around the edges of the glass (then you don't need to tape the perimeter of the glass). 4. FOR PROFESSIONALS: If you are pretty quick at masking, it is NOT much faster than masking (if you want to avoid getting it on the edges much). If you are doing low quality work and don't care that it WILL NOT bond to the wood or old paint at all, and will flake off later, then you don't need to pre-tape. If that's the case, then YES... this is faster than masking, especially for new construction interior glass that is clean. BUT I ALSO TRIED THE OTHER PRODUCT (Jasco Liquid Masking), in ALL the same scenarios above... and it was HORRIBLE... took MANY hours to scrape it off a few panes of glass. NONE of the scenarios worked well. It practically bonded to the glass. Good luck.
