Testing Instagram Influencers’ Product Recommendations — Jasco Mask & Peel Liquid Masking Tape & Primer

Over the past few months, I’ve seen about ten DIY Instagram influencers recommending a product called liquid masking tape and primer. I’ve seen two different brands recommended, and the one I found locally is Jasco Mask & Peel.

The Instagrammers I follow rave about this product and how amazing it is, so when I was ready to paint the 15-lite door in the home gym this weekend, I picked up a quart of Jasco Mask & Peel from Home Depot to test it out and see if it lived up to the praise.

The product can be brushed or sprayed, but obviously, I needed to use a brush. The directions also said to apply a thick coat, so I didn’t try to be neat about it on the glass. Since the product can be used on the wood also (that’s the selling point — it goes right over the glass and the wood), I did try to be neat about the part that got onto the wood parts of the door. And I did find it a little difficult to get those areas smoothed out so that they didn’t show brush strokes.

It took me about 20 minutes to paint the liquid mask onto all 15 glass panes, and then I had to let it dry before painting the door. The product goes on white, and then dries clear. Once it’s clear, it can be painted.

Well, this is where convenience and ease of use of this product kind of waned for me. I began applying the mask at around 9:00pm, and I was expecting it to dry quickly (I was expecting an hour at the most) so that I could apply two coats of paint and be done with the door before I went to bed. But when I finally decided to turn in for the night at around 11:20pm, this is what the door looked like…

So after two hours of drying, only two of the 15 panes were completely dry. I have no idea how long the whole thing took to dry because I went to bed. That was frustrating, and definitely not what I had expected. I guess I’ve never heard any of those Instagram influencers talk about how loooong this stuff takes to dry.

By the next morning, it was all dry and clear (this door has frosted film on the other side, which is why you still can’t see through it even though the mask is dry and clear)…

So from that point, it was very easy. I painted the door with two coats of paint, sanding lightly with 220-grit sandpaper between coats. And then once the second coat was dry, I used a utility knife with a brand new sharp razor blade, scored around the edges of each pane, and peeled the mask off of the pane. I have to admit that I really enjoyed that process. 😀

Scoring and peeling all 15 panes was a pretty quick process. It probably took 15 minutes to do the whole door, and there weren’t any places where the paint bled under the mask like it does with tape.

So what’s my overall assessment of the product?

I like it. I’d give it four out of five stars.

I really do like the ease of use, and I like that it does a great job sealing that space between the trim and the glass so that there are no failures and no paint seepage like you get with tape at times. And I really did enjoy the scoring and peeling process at the end. That was very satisfying.

The only drawback was the drying time. I didn’t expect that at all. I expected it to take an hour at most. But when it was two hours later, and it was still not even halfway dry, that frustrated me.

But now that I know what to expect, I’ll know how to work around that in the future. If I’m planning to paint a door on Saturday, I’ll know that I need to apply the masking on Friday night before I go to bed. That way, it’ll be dry and ready when I’m ready to paint on Saturday.

Everything else about it was great! I do recommend it, and I think it’s a great product, just so long as you know what to expect with that drying time, and can plan around that.

Side note: I’m sure some of you spotted and are wondering about that gap between the door and the door jamb at the top of the closed door in the second picture in this post. It’s hard to believe, but when I hung that door and installed the trim, that door was perfectly flat against the door jamb from top to bottom when it was closed. And now, when the door is touching the jamb at the bottom, there’s a big gap at the top.

It’s incredibly frustrating, and it’s because (1) our house is on a pier and beam foundation that is constantly moving and shifting as the ground moves and shifts, and (2) we’re experiencing horrible drought conditions here, and have been since early last year. Our lake, which is the source of the city’s drinking water, is down so low it’s a bit scary, quite frankly.

And of course, the drought conditions affect the soil, which affects our foundation, which affects everything about our house. I’ve seen shifts and cracks and gaps in the last year that I’ve never experienced in our almost-ten years in this house. For a while, I almost couldn’t open the back door in the bathroom that leads out to Cooper’s yard. Then we got a good downpour, and the door became easier to open and close. But we haven’t gotten anywhere near what we need in order to restore the soil to pre-drought conditions so that the gaps and cracks close up. So for now, I live with it, which is quite the challenge for a perfectionist like myself. 😀

  1. A great review and trustworthy. When I hear ‘influencer’ I immediately think ‘car salesman’…the goal is to get someone to buy something. And you pointed out probably the only draw back which wouldn’t be one if the influencer had been complete with the recommendation. On your experience it is a product I would try and share your experience. I so appreciate your honestly with products and experiences. Thank you.

  2. Thank You for the post about the Jasco Mask & Peel. I’ve never realized there was such a thing. I really like a clean crisp line when I paint and it is really hard to get with tape.
    I wonder if it took so long to dry because it was an outside door and was cold? Maybe it won’t take so long in warmer weather and inside walls? Anyways… I am loving how your home gym is turning out!!

    1. This is actually an interior door. This is the door between our home gym and bathroom. We keep our thermostat between 67 and 69 at all times, so I don’t think the temperature was a factor.

  3. I’ve seen that product before too, and I would choose it in a heartbeat over taping or trying to just be precise. Yours turned out great!
    Re:foundation moving, we added foundation drip irrigation all around our house on a regular schedule to run and it has made all the difference. We are in N Texas where it also is a really huge problem. It’s worth the expense in watering because repairing foundation problems is soooooo expensive.

  4. So glad you reviewed this. I almost bought it several times, and then read some review and was afraid I would hate it. I almost think I remember someone complaining about the drying time. I guess as long as you plan on that it would not be a big deal. But, coming from you, it is a really good review, and I will try it next time. Thank you!

    1. PS) I looked at an older review you did for the little (battery) light for over art work, just recently. Not sure why I saw it now, but I’m happy I did – those lights are so nice but there is never a plug nearby, and I would hate a cord anyway. Keeping that review for future needs as well.

  5. Thanks for trying that product out and showing us! BTW what do you do when paint gets under the tape? That happens to me all the time and I end up having to use Clorox wipes while the paint is still tacky, to clean up the mess and it takes about as long as the painting does.

    1. It depends on what I’m painting. On a door like this, I’d just let it dry and then use a flat razor/scraper to remove the paint from the glass. On most projects, I avoid the bleed under the tape by sealing the edges with paint first. I share more about that here: https://www.addicted2decorating.com/stripes-in-the-hallway-how-to-paint-perfect-stripes-on-the-wall.html

      If that’s not possible, I just spend some time touching up any areas where the paint bled under the tape. It’s a pain, but I’m too much of a perfectionist to leave it.

      1. Hmm, so the benefit of using this is that you don’t get paint bleeding under it? It sounds like a very interesting product, but I’m a bit confuse about how is it better? If you have to mask the wood, in this example, to apply it, how does it make a difference? Or is it very thick or something and easy to apply without touching the surface to be painted?

          1. So how were able to paint the wood when the liquid mask was on it? I feel I am missing something. I am not very capable when it comes to diy but this sounds like something that would be helpful. Did you simply just peel the mask off the wood part when you needed to paint it?

            1. When it’s brushed onto wood, there’s no need to remove it. It just acts as a primer. Once it’s dry, you paint right over it. It only gets removed from the glass.

          2. Aaah!!! When you said in your post that it can go on wood, I thought to be used as a masking layer again! Ok then, if it can sit on the wood and be painted, this sounds amazing!

  6. When painting around glass, isn’t it just as fast and easy to paint with NO tape, and then use a flat razor scraper to clean off the glass? It’s especially easy when you scrape the paint off when it’s dry, but fresh.

    1. Sandra, I agree. My first house was from 1933 and had french doors and windows with many tiny panes. I found it no problem at all painting the trim and then removing any excess around the edges, in fact I enjoyed it.
      And much cheaper than buying a gallon of a product! This method seems way more time consuming.

  7. I’m so glad you tested this, Kristi! I had seen it raved about, also, and was considering buying it to use on my french doors when I paint them. I totally trust your judgement, so get some I will! And good to know about the drying time! Thank you! xo

  8. What a great product, thanks for giving us your review. I would like to know how far your thing a quart will go because I see this stuff isn’t cheap.

  9. Thanks for the product review. I never try a product recommended by an “influencer “, really I regard those as just an advertisement. But your honest review is next level!
    We live in Vermont and our house experiences “frost heaves” every year. We cannot open our outside basement door at the present time, but give it a month and it will be just fine. 😂😂
