Installation Guide

GenStone Pillar Panels will apply over any structural wood post up to 8”x 8”(actual size). The post
must measure 8”x 8” (outside box measurements) by the height you want to make the stacked stone
pillar. GenStone pillar panels are 48” tall and may be cut to make a shorter stacked stone pillar, or
stacked to make a taller pillar. We recommend you use treated wood for the building of the boxes.
5.50” x 5.50” SQUARE POST EXAMPLE
Rip the 3½” side of a 4’ long 2’ x 4’ board lengthwise to make 2 each 1
¾
” wide strips 48” long. Cut
that strip into twelve 3
½
” pieces (shimming strips). Temporarily place one of the GenStone pillar
panels up against the post and mark the post with a pencil delineating where the top edge of the
pillar is to be positioned. Then attach a ring of 4 shimming strips around the bottom, center (24”), and
top (48”) of the post.
Make sure the top ring of pieces is lined up below the line on the post. The pieces should be screwed
or nailed (pre-drill if necessary) to the post with the ripped edge against the post. Please use 2
fasteners per shimming strip. Finally, cut two 8”x 48” strips and two 7” x 48” pieces of 7/16” OSB
or ½” treated plywood. Attach the four pieces of sheathing on the post with nails, staples or screws
into the shimming strips. Start with the 7” pieces on opposite sides then nish with the 8” pieces on
opposite sides. The 4 GenStone Pillar Panels should be attached to the box using a S-shaped bead
of construction adhesive appropriate to use with foam and wood. (PL300 or equivalent) Then hide a
series of 8-10 trim head screws (per side) between the stones, holding the panels to the box.
3.50” x 3.50” SQUARE POST EXAMPLE
The instructions are almost the same as for the 3 ½”x 3½” except you will substitute twelve 5½”
pieces of treated 1’ x 2’ or 1’ x 3’ (¾” thick material) for the rings around the post (wide side of these
pieces against the post).
