How to Install a Stacked Stone Column Wrap

How to Install a Stacked Stone Column Wrap Many customers are extremely satisfied with how easy it is to install our columns.  Using just some simple tools, they are able to get them up in no time at all.  Below, we’ll show you how to install a faux stacked stone column wrap over an existing support post. Installing a faux stacked stone column wrap is easy. Installing a faux stacked stone column wrap over an existing support post is easy. Before we begin, here is the list of simple tools you’ll need:
  1. Exterior Grade Screws — use screws that are long enough to go through the column. We
recommend a narrow head screw (such as a #1 Roberson head trim head screw) to make touchup easier and less noticeable.
  1. Construction Adhesive/Glue — we recommend either PL® Premium Construction Adhesive, PL®
Premium Advanced 8X Construction Adhesive (which has 4X faster bonding), or Great Stuff Pro.
  1. A saw for cutting columns – 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.
  1. Tape Measure
  2. Level
  3. Caulking gun for applying the Adhesive/Glue and Caulk.
  4. FauxColumns color coordinated textured caulk.
  5. 2" x 4" lumber as needed
  6. Exterior grade plywood as needed
Installation Instructions: Make sure the column wrap is clean before you being installation.
  1. Be sure that the columns, the column cap and posts are clean and dry before you begin. Approximately 24 hours before the installation, expose the post, the column wrap, the lumber and the plywood to the same general humidity and temperature. Make sure not to expose any of these materials to direct sunlight, or in close proximity to heat.
Construct a sub frame for your faux stacked stone column wrap next.
  1. To get a secure and sturdy base for the column wraps, you’ll want to construct a sub frame. Make sure that this sub frame, along with the plywood, fits within the wrap’s dimensions.  To maintain a steady, upright connection to the existing wood post, this frame needs to be securely centered on the support post.
Apply the exterior grade plywood to the wood sub frame.
  1. Next, apply the plywood to the wood sub frame. This will serve as the surface that you’ll attach the column wraps to.  For proper sizing, make sure to dry fit the wraps to the structure.
Hint: leave a little extra room for the thickness that will be added by the glue that’s between the plywood and the column wraps. Apply a bead of glue to the perimeter of one of the column wrap pieces.
  1. On the back of one of the wrap panels, apply small beads of adhesive along the perimeter, about one inch from the edge. Then, in a zigzagging pattern, apply a little more adhesive to the back of the panel.  Make sure the beads of adhesive are no more than 4 inches apart.  Add a little bit of glue inside the fingers of the panel, which interlock.  Then apply a little bit of the textured caulk along the edges of the interlocking fingers, where they’ll join with the next section of the column wrap.
Apply the wrap panel to the plywood.
  1. Apply the column wrap to your exterior grade plywood. Gently press and twist the wrap panel onto the plywood, to ensure secure contact with the adhesive.  The PL® Premium Advanced 8X Construction Adhesive will help to keep the wrap panels in place on the plywood, giving you some time to get the other ones up.
Fit the interlocking fingers together.
  1. Repeat step 4 and 5 for every other section of the wrap. Be sure that the fingers securely interlock.
Make sure the wrap is level and the fingers fit together nicely.
  1. Make sure the interlocking fingers of the panels all fit together securely, and that the column wraps are level. Begin to fasten the wraps to the plywood all along the perimeter with screws, spacing them at approximately a foot apart.  In the middle sections of each panel, place additional screws about 1 per square foot apart.  It’s best if every screw is slightly recessed below the surface of the panels.  Make sure not to tighten the screws more than needed.Hint: Concealing screws in crevices, beneath protruding rocks, or grout lines will help to give the column panels a cleaner, more realistic look.
Wipe off excess caulk with a damp rag before it dries.
  1. Before the caulk dries, use a damp rag to wipe off any excess caulk that might have been pushed out between the two wrap panels. You can also use the textured caulk to hide the screw heads.

  1. If you are installing multiple rows of columns, you can now start the next row up. Repeat steps 4-8 for the next row of column wraps to be installed.
The cut out in each of the two cap halves allow them to sit around an existing support post.
  1. A "Two-Piece" Column Cap is featured with Norwich columns. This cap comes as two diagonal halves, which are split through the center, so as to help hide the seam.  The cut out parts in the halves of each cap allow them to be placed around existing support posts.  PLEASE NOTE: depending on the post size, additional cutting or shimming and caulking may be required.  The opening in the cap center is 6" X 6".  Proceed to Step 12.
If using a solid cap, no opening/no post, just proceed to Step 12.
  1. If you’re using a solid cap with no opening or post, continue to Step 12.
Apply glue to the tops of the column wrap sections and to the wood sub-structure to secure the column cap in place.
  1. To secure the column cap in place, apply adhesive to the top sections of the column wraps and to the wood sub frame. Set the cap in place, pressing down firmly. If using the two piece cap, glue the two halves together around the existing post. Then follow up with screws to hold the cap piece to the panels and sub-structure (toe-nailing through the bottom on a diagonal).
  1. Lastly, using the paint from the Touch-up Kit, paint the wraps, screw heads, and textured caulk as needed. Click here for more details on Touching Up Panels. Stand back and admire your handiwork. (In this project shown, additional wood was added to the structural support post to create a dramatic tapered look.)
When installing your columns, be sure to follow and obey all safety rules and recommendations set forth by tool manufacturers.  Always follow any, and all, local, state, and federal building codes. Always comply with any specified clearances set forth by the manufactures of stoves, fireplaces, furnaces, and any other heat sources, as well.
