Materials Used For Reverse Decoupage On Glass

Steps For Reverse Decoupage on Glass Windows

Step 1: Prepare the Window

The first step in this process is to prepare your old window. Use a metal putty knife to scrape off any old paint and caulking from the glass. This step is crucial as it ensures that the glass is clean and ready for the decoupage medium. Once all the old paint and caulking are removed, clean the glass thoroughly with rubbing alcohol to remove any residual debris and dust. If there’s any flaking paint on the window frame, sand it smooth for a polished finish.

Step 2: Apply Decoupage Medium

Now that your window is clean, it’s time to apply the decoupage medium. Note: Since we are doing a reverse decoupage technique, you will be applying the medium to the back side of the window; the side you just scraped and cleaned. Using a sponge brush, apply a generous layer of Paint Couture’s matte decoupage medium about three to four inches down the glass and all the way across. We’re not covering the entire glass just yet; we’ll work in sections.

Step 3: Lay the Decoupage Paper

This is where the magic begins. Place your decoupage paper upside down on the back side of the glass. This may sound counterintuitive, but since it’s a reverse technique, the front of the paper will be visible from the front side of the glass. Align the paper carefully and use your hands to flatten it, ensuring it’s straight and wrinkle-free.

Again, work in sections, applying the decoupage medium and then laying the paper. Don’t worry about getting all the wrinkles out initially; just focus on positioning the paper correctly.

Step 4: Seal the Paper

After the paper is adhered all the way down on the glass, apply another layer of decoupage medium. You do not have to work in sections for this part; just make sure you get nice coverage. This is just like you would do in a traditional decoupage project; which helps to seal it properly. Now, to remove any wrinkles, place Saran Wrap over the paper (working in sections ) and then roll a brayer over it. This technique not only smooths out the wrinkles but also pushes out excess decoupage medium to the edges, which can be cleaned up later. Oh, and don’t forget to brush on one more coat of decoupage medium after removing the Saran Wrap.

Step 5: Paint With White Paint

Now that our medium is dry, it’s time to enhance the vibrancy of the decoupage paper. Grab your white paint and give the entire surface a uniform coat. This step is crucial because using a dark-colored paint can make the colors appear dull. By painting with white, we ensure that the colors really pop! Oh, you can go ahead and paint the window frame white as well. Allow everything to dry thoroughly.

Step 6: Turn Window over and Paint Frame

Now it’s time to flip our window over and paint the front side of the frame. I recommend using two coats of DIY Paint’s Layered Chocolate, a beautiful dark brown color that complements our sunflower design perfectly. The great thing about this step is that you don’t have to be overly cautious about getting paint on the glass since it can be easily scraped off later. And hey, if you need to speed up the drying process, whip out that trusty heat gun!

Step 7: Wax the Frame

To add that extra touch of elegance, let’s wax the frame. Start by applying a layer of clear wax. This step is essential because it allows us to manipulate the colored wax more easily. Once you’ve applied the clear wax, go ahead and add a layer of gold wax (DIY’s Golden Rule) for a subtle shimmering effect. This combination gives the frame a rich and elegant look that beautifully complements our decoupage paper.

    Step 8: Add Reflective Glass Chips

    Let’s add some sparkle! Clean the front side of the glass with rubbing alcohol to remove any fingerprints or smudges. Now, arrange the reflective glass chips (bronze and green) around the design as desired. These chips add an extra layer of interest and texture to your window, making it truly eye-catching.

    Step 9: Pour Epoxy Resin

    Time to seal the deal! Mix the epoxy resin according to the instructions, making sure you have equal parts of A and B. Stir the mixture for at least three minutes, scraping the sides and bottom of the cup. Now, wearing your disposable gloves, pour the resin over the glass chips, starting with a drizzle over the chips and then spreading it evenly over the rest of the window. Using your gloved hand, spread the resin evenly around and use a heat gun to pop any bubbles that form. If needed, repeat this process to achieve a smooth finish.

    Tip: For my first coat of resin, I mixed up three fourth’s of a cup which was not enough. There were a few dimples on the surface when it cured, so I then mixed up a cup and a half (12 oz.) and re poured. That seemed to be the perfect amount for a nice, smooth finish.
