I picked up this old window in the spring of 2013. I was driving down the road by my son’s preschool on trash collection day when this window caught my eye. They propped it up against the mailbox in front of an antique colonial farmhouse beside the trash, as if the owner knew there was a possibility someone may consider it a treasure.

Before

Of course, I had to pull over! There were two broken panes of glass, and as I carefully avoided the broken glass to put it in the back of the car, I noted that it actually came from the barn they were renovating, weathered gray barn wood and all. Score!

If you aren’t lucky enough to snag a free window on trash day, thrift stores and salvage yards are a great resource. You can also shop for them online!

I had a few ideas for what to do with the window:

  • transform the old window into a chicken wire message center
  • paint the panes with chalkboard paint
  • add photos to the window panes
  • transform it into DIY window mirror wall decor

I suppose now it’s pretty easy to see which option I chose!

I have been wanting a window mirror for a while. As soon as the idea struck of transforming the window to a mirror, I immediately knew that’s what my barn window should become.

I have been dying to try out glass-effect spray paint, so I already knew my method for transforming the clear glass to a mirror-like finish. I also knew I wanted a slightly antique-look, so I used the method I describe below to distress the glass.

It was the details related to this window that made the project a little more complex, but definitely not impossible.

Replacing Glass in a Glazed Window

This was actually an authentic glazed window, and the putty that originally held the panes in was chipping away. I was reasonably sure that the chippy paint on the backside of the window was lead.

Before I could replace the glass, I somehow had to remove the glazing without disturbing the chippy paint. Since the edge of the glazing was so close to the chippy paint, this made me very nervous!

Sealing Potential Lead Paint

Zinsser Peel Stop turned out to be a perfect solution for this project. Before anything else, I sealed up the back of the frame with the Peel Stop, just in case. I could remove most of the glazing safely, without chipping off the paint. I left the glazing that had been painted.

The next step was replacing the glass in the two missing sections. I took my measurements and headed to Lowes for replacement glass. This was tricky, as the remaining window glazing made it difficult to get a perfect measurement. I ended up having to take the glass back to have it re-cut. In retrospect, I should have just hauled the window in there! Ultimately, I prevailed and could get pieces that slid under the glazing.

I painted the two cut pieces before repairing the mirror. The mirror-effect spray paint is very easy to use- just make sure you have proper ventilation! This stuff smells like nail polish multiplied. It also dries very quickly.

Since my new pieces of glass were less rustic-looking than the old glass in the window, I did some light distressing with a 25% vinegar 75% water solution and a paper towel. I spritz the drying panes with the solution. The vinegar/water removes the mirror-like finish easily, and I just dabbed with the paper towel to pick up the droplets. Then I added another coat of Looking Glass.

Prepping and Painting the Antique Mirror

I taped up the backside of the window mirror, using masking tape and masking paper. After I prepped it, I sprayed a coat of the looking glass paint.

As soon as it dried, I sprayed a second coat, then a third. The original panes were already very aged and rustic looking, so I didn’t need any of the vinegar/water solution. There were spots where the mirror-effect spray paint inexplicably beaded. I assume there was something on the old window that prevented it from curing. I just kept layering the finish until it was no longer possible to see the shadow of objects behind the glass. It’s still slightly translucent, but I am okay with that!

After everything dried, I secured the two new panes with glazing clips. I had wanted to do this step last, so the clips didn’t show through. Now the mirror-effect paint hides the clips!

The Result

I have to say, I am quite in love with this technique for creating DIY window mirror decor! The mirror looks like something you’d spend a lot on at an expensive home decor store, but for under twenty dollars (free window, $7.58 for replacement glass, 8.48 for the mirror-effect spray paint and $1.14 for the clips).

Notes

Replacement Glass: After finding your antique or salvaged window, measure for any necessary glass replacement. Have replacement glass cut at the hardware store. Arrange replacement glass on masking paper and apply multiple coats of mirror-effect spray paint in a well-ventilated area. Optional: follow distressing method below between coats.

Optional Distressing Method: to distress new or replacement glass, apply a 25-75 vinegar-water solution with a spray bottle. Simply spray on the solution to the mirror-effect paint before it's completely dry and dab with a paper towel. Apply another coat of mirror-effect spray paint after. Repeat until ideal patina is achieved.

  1. Hi Nina,

    I love this six pane window. I just printed out six botanical prints and they would look amazing using a window like this!

  2. Hi, I’m a little behind, I just saw this post and it is exactly what I was looking for. Can you tell me how you applied the vinegar/water solution? Can you also tell me what the ratio of the solution is? THANKS, love is idea.

    1. Hi Lynn! I put a half vinegar, half water solution in a spray bottle (can be found for $1 in the Target travel bottle section). I hope it turns out great for you! :)

  3. This is awesome! I’ve been working on my industrial dining room (with a bit of traditional mixed in) this weekend and need something for the wall opposite my feature wall. May give this a whirl!

  4. I am so excited with what you have done….I have several old windows that I also “picked up” and I need an embellishment in my laundry room and I am going to try this…..Thank you so much and Happy Valentines Day……. ♥

    1. Hi Alice- it is not completely transparent- I’m not sure that it would really work for that. Krylon does make a frosted glass spray paint I think, although I’ve never used it myself.

    1. It’s “mirror-like”- but not completely a mirror. It looks like a very old and somewhat beaten-up mirror that you would find in an attic :)

    1. You’re very welcome! Thanks for stopping by! Just an FYI- I ended up finding the spray at Walmart- my local craft stores had discontinued it!
