Tools and Supplies You'll Need

You can install Norwich columns easily using tools found in almost everyone's toolbox. To complete your project you will at least need these basic tools:

  1. Exterior Grade Screws — use screws that are long enough to go through the FauxPanel and firmly attach to the wall behind the FauxPanel. We recommend a narrow head screw (such as a #1 Robertson head trim head screw) to make touch-up easier and less noticeable.
  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. A saw for cutting panels – a circular saw, jig saw, band saw, table saw, or hand saw, it is your preference. Any woodcutting blade used with these saws will work great and cut smooth and easy.
  4. Level
  5. Caulking gun for applying the Adhesive/Glue and Caulk.
  6. FauxColumns® color coordinated textured caulk.
  7. 2" x 4" lumber as needed
  8. Exterior grade plywood as needed


Below are directions on how to install Norwich faux stone post wraps.

1.) Before you start, make sure the surfaces of all column wraps pieces, posts, and column cap (if being used) are clean and dry. You’ll also need to acclimatize your faux stone post wraps, post, plywood and other lumber to roughly the same temperature and humidity for about 24 hours prior to installation. Do Not store any of these materials in direct sunlight or close to heat sources.

Create a base using lumber to anchor your installation and provide the best look.

2.) To ensure a secure and well-anchored base for your column wraps, you’ll need to construct a sub-frame. This structure (including the plywood) will need to fit the inside dimensions of your column wraps. You will also need to center this frame on the existing support post and securely shim to maintain a solid and plumb connection.

Lumber and plywood create a substructure to better affix your faux stone post wraps.

3.) Apply exterior grade plywood to the sub frame to serve as a surface for installing your faux stone post wraps. Dry fit the column wrap pieces onto the structure to ensure proper sizing.

Hint: Leave a small amount of extra room for the thickness added by the adhesive that will be used between the panels and the plywood.

Apply glue or adhesive to your column wraps as shown for a strong hold.

4.) Apply a bead of glue/adhesive along the perimeter of the back of a column wrap piece roughly an inch from the edge. Additional glue/adhesive should be applied to the rest of the panel back in a zigzag pattern with beads of glue/adhesive no more than 4" apart or so. A small amount of glue should be added to the inside of the interlocking "fingers" of the column wrap. Then add a small amount of color matched textured caulk to the edges of the "fingers" where they'll join with the next section of the wrap.

Install the faux stone post wraps to your sub-frame with a slight twisting motion.

5.) Affix the faux stone post wrap panels to the plywood. Use a slight twisting motion to ensure good contact between the glue/adhesive and the plywood. The PL® Premium Advanced 3X Construction Adhesive will help to hold the individual pieces in place on the plywood during installation and give you some working time to put the other column wrap pieces up.

Make sure to interlock the column wrap fingers properly for a seamless appearance.

6.) Fit the interlocking "fingers" together and repeat steps 4 & 5 as needed for each of the other column wrap sections.

Level the column sections and then add screws as instructed.

7.) Make sure the constructed column wrap is level and the fingers all fit together nicely. Fasten the panels to the plywood with screws all around the perimeter at roughly one foot apart or less. Additional screws will be needed in the middle of each section at a rate of about 1 screw per square foot. All screws should be very slightly recessed below the surface of the panels.

Do Not over tighten the screws.

Hint: Placing screws under protruding rocks, in crevices, or grout lines will help conceal them and give a cleaner, more realistic look.

Use a damp rag to wipe away any excess caulk that may have squeezed out.

8.) Before the textured caulk dries, be sure to use a damp rag to wipe off any excess that may have squeezed out from between the joints of the column wrap pieces. Additional textured caulk should be used to conceal screw heads as well. Click here for more details on caulking panels.

Continue as necessary if your column designs are taller.

9.) If you’re installing multiple rows of faux stone post wraps, you can start installation on the next row up now. Repeat steps 4-9 for the following row(s) of column wraps to be installed.

Note: The column panel pieces were designed to butt up to each other bottom to top. This joint should also be caulked for a tight seal with a seamless look.

Split column caps can be used to give a final touch to your column wrap designs.

10.) The two piece column cap comes in 2 diagonal halves. The half sections are split along the diagonal to help hide the seam by following the original crease of the cap. The cut-out in the two cap halves allow them to fit around an existing Porch Support Post.

PLEASE NOTE: Either shimming and caulking or additional cutting may be required depending on the Post size, Cap center opening is 6" X 6". Proceed to Step 12.

Solid caps help finish up faux stone post wrap designs without an extended post.

11.) If using a solid cap (no opening/no post), you may proceed to Step 12.

Secure column caps with a bead of glue around the top of the column wraps and frame.

12.) Apply glue to the tops of your column wraps and the wood sub-frame to secure the column cap in place. If using the two piece column cap, glue the two halves of the cap together around the existing Post. Set the column cap in place, pressing down firmly. Screws should be used to hold the cap together and/or held securely to the wrap pieces and sub-frame.

Now you're done with your column wraps installation.

13.) Finally, use the paint from the Touch-up Kit to fix up your faux stone post wraps, hide screw heads and blend textured caulk for a more seamless look. Click here for more details on Touching Up Panels. Stand back and admire your new faux stone columns.

Note: In this project shown, additional wood was added to the structural support post to create a dramatic tapered look.
