Ready to give foam crown molding a chance in your home? Gather your materials and use these quick and easy installation instructions to help you get started on your new project:

Step 1: Paint First!

The foam crown molding will come in a color that will more than likely not match your home’s décor. You will need to prime and paint it first before you install. Give it time to dry before installing the foam crown molding.

Step 2: Corners Come First

Start with the corners of the room for installation first. No nails, hammers, or stud finders needed for this step! Simply place the adhesive on the back of the foam crown molding and press it onto the wall and into the corner!

Step 3: Measure the Gap

Take your tape measure and find the distance between the two corner pieces. Cut the foam crown molding piece to the desired length based on your measurement.

Step 4: Fill in Your Seams

Using the spackle you have in your toolkit, go back to each seam around the room and fill it with spackle. Then, sand it down so that the surface is nice and flat. After you sand the seams, apply one more coat of paint. Let dry.

Step 5: Caulk Away

The last step requires lots of caulking! Go to the top of the foam crown molding and caulk the horizontal seam. Then, move to the bottom horizontal seam. Make sure to wipe away any excess caulking that may be left using your flat knife and rag if needed!

Many homeowners who were around in the ’70s and ’80s have a strong aversion to the use of styrofoam in their home (or in their lives at all). This is because back in the ’70s and ’80s, styrofoam was known for emitting gasses or causing environmental issues by simply existing.

Today’s technology has redesigned the way styrofoam is made and it no longer includes the CFCs of those earlier times.

Now, the foam crown moldings are made from the same styrofoam that is found in your cooler, coffee cups, and many other places around your home! You can rest assured that this foam crown molding will do nothing in your home except provide a beautiful appearance for your guests!
