Customer Reviews for FastMasQ 1 qt. Liquid Masking Tape Interior/Exterior Primer

Love it when a product works the way it is supposed to. I used this to paint several wood french doors and it made what would be a tedious job so easy! No using a ton of blue tape (that always leaks,) no scraping the glass of paint residue (not supposed to do that on the tempered glass in my doors, anyway.) I viewed a ‘This Old House’ Youtube video, and followed the method the professional painter used. Do one coat of this product, allow to dry, do a second coat, dry at least 4 hours, then apply your paint. Use a sharp blade (use a slanted, snap-off tip blade and snap off the tip every few panes to keep it sharp,) to score around the panes, carefully, then peel off the dry ‘sheet’ of product. Nice, clean edges around the pane. The only issue I can see would be operator error (i.e. not coating well, not doing 2 coats with proper dry time, not being precise when scoring around the edges.)

This product works so slick! We have an 1889 house with very old windows that are individual small panes of glass. To tape these all off would have been a nightmare and could possibly have broken the very old glass. We painted this on the glass and went about painting the skinny wood frames. When we were done, we took a razor blade and scored around the edges and this product pulled right off with no paint left behind. I highly recommend this product. It is a little costly but it is worth every penny!

I had two decorative windows with a diamond mission sash I needed to paint. This stuff was excellent. I got vey clean lines and the painting was a breeze. I am going to use it for my French doors next.

Did exactly what it’s advertised to do. Covered glass during priming and painting and was removed leaving clean glass

Saved tons of our time. Our neighbours suggested to use it and we are not disappointed!! Great as advertised!

This stuff worked great!!! I used it when I painted a set of French doors in my office. It saved me the trouble of taping off 40 little window panes. Everything came off clean, no paint on the windows. It was amazing. I'll definitely use this product again.

Easy to use and did an excellent job.

As long as you apply a thick coat, it peels off glass very easy.

Excellent. I had two sets of french doors, a total of 40 panes of glass, to edge on two sides, so that's 80 panes. each pane has 4 sides so that's 320 pieces of masking tape. Good grief. I painted the the liquid tape on as if it was the primer; did all 80 panes in about 2 hours. Came back two days later put on final coat. Two days later I edged each pane with a sharp knife and with a scraper lifted all the liquid tape film off the glass. No problems whatsoever. Great product.

Very pleased with this product. Goes on and comes off super easy and leaves the glass pristine underneath. Saved me a ton of time on prep for my french doors and the finished product has very clean lines.

Made the whole process of painting our French door so simple. Clean lines with no running. The door looks better now than when the professional painters did it.

Liquid Masking worked just as it said . No fuss and no mess. I have already recommended this product to friends.

Worked great my door windows. Used two coats before painting window frames. I thought at first it wasn't going to work, then shoot dang, peeled off like a nice little film after scoring around the edges.

I needed to repaint our French doors but couldn’t fathom taping off 24 little windows. I discovered this product and it was amazing. Works exactly as it says.

This was fantastic for painting the trim around transom windows and french door glass. Saved time with a great result!

I never worked with anything as satisfying as this product. It couldn't be easier to apply and after you are done to remove, great product!

This stuff really works. I didn’t use two coats and I bought two cans. I barely used half a can if that!! After I painted, it did exactly what it was suppose to do. Great stuff

Follow the directions exactly relative to temperature, application (two coats are a must,) and removal time and this absolutely works like a dream. It's amazing. I am not a pro (barely qualify as a regular DIYer) and don't have the steady hand to cut in so for me this was infiinitely better and cleaner than tape masking. I was painting small windows on several bookshelf door units. True, the product is not cheap, but it was worth it for the end result. I can understand the dry time and expense wouldn't be cost-effective for pros.

My first experience with any similar product,so nothing to compare to. And my glazing and painting technique was likely not professional. Nether the less, I found it performed much better with two coats, and had to let it dry much longer on second coat. Even then, it pealed Not as cleanly and trouble free as I would have hoped for. Will try a different brand next time.

It worked as advertised! Only tip I’d say is to peel it off in the cool of the day. Tried to peel it I the heat and it was a mess. Tried the next morning and it was easy. Great product!

This stuff makes painting along window tines or mirror frames, etc fast and easy. I recommend 2 coats and after the dry time, paint and then use xacto knife or similar to cut along the paint edge, peel back and you have perfect edges. Peel slowly in case you didn't cut completely through. It is awesome stuff!

Painted on around faded logo on camper. Spray painted logo. Would not peel off! Stuck to camper fiberglass.
