Installation Guide

GenStone Pillar Panels will apply over any structural wood post up to 8”x 8”(actual size). Please measure the diameter
of your posts. A treated 4” x 4” post actually measures 3
½
” x 3
½
”, a 6’ x 6’ is actually 5
½
”x 5
½
”, and an 8” x 8” is actually
7
¼
”x7
¼
”. The idea is to build a box over your post measuring 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.

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).
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.
