Product Description

Jasco Liquid Mask & Peel is a liquid tape and primer that's faster and easier than using painter's tape. Use to paint window frames like a pro without using masking tape. Save time and make a hard job easy! Brush on glass and trim, paint trim, then razor and peel. For Pro's and DIY'ers, Jasco is the premium brand of solvents, thinners and removers to deliver the highest quality for a variety of products. DIRECTIONS FOR USE: Shake or stir well. Clean glass and trim before application. Brush or spray a very thick coat onto glass and edge of trim – (it primes the trim, too.) Wait until it turns from white to clear when dry – a hair dryer or fans can be used to speed up drying time. Apply oil-based or latex paint to trim. Score along the edge of trim with a new razor blade. Using a scraping tool with a new blade, lift the dried Mask & Peel off the glass. Peel within 2 weeks.

    WOW.. Works great!!
    Clean windows, apply with a 2 inch brush, let dry full day, paint areas, let dry. Lightly score around window area.
    Use a safety edge razor blade, lift one area. Gently pull paint away like mozzarella cheese. Anything that’s left behind. Can be come off with the razor blade and it’s perfect all thumbs up product.

    First time using this mask off and painted over 5 foot windows in my living room before using a paint sprayer sprayed right over the windows in the windowsills and not a drop of paint on my windows love love love this product and I can’t believe I’ve never used it before. After drying it just peels right off like almost like a latex it’s amazing!

    Great idea. Difficult to apply thick enough for easy peel if windows are upright. The product tends to run when applied with any thicknesss. I used on a paned door with the door upright. It would have been as easy to scrape the paint off, as to scrape the mask film off. I won't use again.

    This product works well. Definitely be generous when applying. Takes a little time but less than taping

    Reviewed in Canada on January 3, 2025
    Bought this to use when doing our doors with 21 separate window panes each. Multiply that by 4 doors, both sides - this was a life saver.

    Works great and saved tons of time. Pack it on and let dry to clear - paint away then peel it off. Such a breeze.

    Reviewed in Canada on December 20, 2024
    Cuts painting time because instead of masking window, you just paint this on the glass and allow to dry, that way when you paint you door and if you happen to get paint on the glass you can just peel it off with a razor blade when you have completed your paint job.

    4.0 out of 5 stars Masking Liquid works well
    Reviewed in Canada on November 17, 2024
    This masking liquid make painting window sashes much easier and leaves clean lines. You need 2 coats of the product. Let the first coat dry and apply the second. Allow several hours to 2 weeks to remove, weather dependent. Use sharp utility knife to cut the edge and a razor paint scraper to start the peeling process. It is time intensive to paint window trim. This saves time, but it still takes a while. Great results though.
  • Chris
    5.0 out of 5 stars Great product
    Reviewed in Canada on April 8, 2024
    This works perfectly if you follow the directions. Those with poor reviews did not apply it correctly. You need to put it on thick, if not it will not peel off and you will be left needing to scrape it off and will be much more difficult than just letting your paint get on the glass and scraping it. You are supposed to get some of it on the frame as well so it completely seals, you can paint over what got on the frame just fine. Once scored with a knife you can then peel it off the glass. It leaves a very clean edge. One tip, although you want to apply it thick don't leave blobs of it right where the glass meets the frame as it will dry with that blob there and after painting when you score you will likely score off the blob which has the paint and therefore will expose the previous finish. You can see one of these blobs in the corner of the middle pane of glass in the attached picture. Just make sure to pull back that blob from the edge without making it to thin and you will be fine. Foam brush worked well to apply.
