Tools and Supplies You'll Need

To complete your project you will at least need these basic tools:

  1. Finish Nails - use nails that are long enough to go through the Trim and firmly attach to the wall behind it. If the application is on the exterior or in a wet location we recommend exterior grade finish nails.
  2. Construction Adhesive/Glue - we recommend either PL® Premium Construction Adhesive, PL® Premium Advanced 3X Construction Adhesive (which has 3x faster bonding), or Great Stuff Pro.
  3. Hammer and nail set (if applicable)
  4. A saw for cutting the trim to fit – a circular saw, jig saw, band saw, table saw, or hand saw, it is your preference. Any woodcutting blade used with these saws work great and cut smooth and easy. (if applicable)
  5. Caulking gun for applying the Adhesive/Glue and Caulk.
  6. FauxPanels® color coordinated textured caulk (if applicable, and necessary)
  7. Touch-up Kit (if applicable, and necessary)
  8. Spaces/box extenderes


The Electrical Outlet Trim can be installed indoors, or outdoors, on any reasonably flat surface that is clean and is in structurally sound condition. The Electrical Outlet Trim should be installed prior to installing any FauxPanels®, so that the Panels can butt up to the Trim.

Note: These instructions cover the installation of the decorative outlet covers only. It doesn't address any specific instructions for what is needed to do the actual electrical work itself. We recommend you consult with a licensed electrical contractor for this.

Select which style of outlet you will be installing:

Installing Electrical Outlet (and/or Electrical Switch) Trim

Installation of decorative outlet covers begins with cleaning and preparation of the surface.

1.) Begin the decorative outlet covers installation by making sure the surface the trim will be attached to is clean. Wipe the surface with a rag. Use a wire brush on harder surfaces. Wipe clean the back of the Trim as well.

Acclimatize the Trim to roughly the same temperature and humidity as the installation surface for about 24 hours. Avoid storing trim in direct sunlight or close to heat sources.

Dry fit the synthetic stone trim to determine placement.

2.) Dry fit the Electrical Outlet Trim to insure a proper fit.

Properly gluing your decorative outlet covers keeps them from slipping or falling off.

3.) Apply two beads of the Construction Adhesive to the back of the synthetic stone Electrical Outlet Trim as shown.

Place the decorative outlet covers with a slight twist for a better glue contact.

4.) Apply the Electrical Outlet Trim to the wall. Use a slight twisting motion to help ensure good contact with the glue/adhesive and the wall.

Give your decorative outlet covers a stronger hold with recessed finish nails.

5.) Begin fastening the decorative outlet covers to the wall with the finish nails. Use a minimum of two nails. Finish nails should be very slightly recessed below the surface of the Trim. Use a nail set to recess finish nails. Use exterior grade finish nails if the Trim is being installed in high moisture areas.

Fill the nail hole on your decorative outlet covers with caulk and touch-up paint to conceal it.

6.) If desired, use caulk to fill the screw or nail holes. (You may want to use the paint from the touch-up kit to help conceal the caulk that has filled the nail holes.) The installation of the decorative outlet cover trim is completed.

Bring the electric box forward to line up with the synthetic stone trim

7.) Bring the Electrical box forward (using the appropriate spacers/box extenders as necessary) and install the outlet cover plate.

Caulk the outer edge of your decorative outlet covers before installing panels.

8.) Before installing the FauxPanels® up to the newly installed Electrical Outlet Trim, apply an ample bead of the Textured Caulk in the crease between the synthetic stone trim and wall.

Wipe excess caulk from around the synthetic stone trim as necessary.

9.) Install the FauxPanels® as directed in the appropriate FauxPanel® instructions. Before the texture caulk dries be sure to use a damp rag to wipe off any excess caulk that may have squeezed out from between the joint between the FauxPanel® and the Trim.

Installing Double Electrical Outlet (and/or Electrical Switch) Trim

For this you'll need two decorative outlet covers and matching textured caulk.

1.) For this you'll need two of the decorative outlet covers to cut to make a trim that will fit a double outlet and/or switch. You'll also need a tube of matching textured caulk to form the grout line between the two trim pieces.

Cut the two synthetic stone trim pieces into

2.) Cut each of the two Trim pieces into a C shape, keeping the legs of the C as long as possible without cutting into the miters at the corners.

Dry fit your two decorative outlet covers to check size and placement.

3.) Dry fit the two pieces together and lay your electrical cover plate on top to check for size. You'll want just enough space between the legs of the Cs to form a nice-looking grout line. If the legs are too long, carefully trim off a bit. Follow the rest of the standard installation instructions listed above to complete the installation.

Give your synthetic stone trim a clean looking grout line as a finishing touch.

4.) The finishing touch is to add the textured caulk to the seams where the synthetic stone pieces meet. This is very important to ensure a weather-tight seal.

Note: The same principle can be used to create Electrical Outlet Trims that will fit triple outlets, quadruple outlets, etc.
