Note: Recommended adhesive for installation is Gorilla Glue.
Warning: precision-machined edges of Poly-Classic Craftsman column components can be extremely sharp. Use of appropriate personal protection equipment is required.

1. Measure overall opening from floor to beam or soffit (must have structural pressure-treated post or lally column for load support.)
|
|
2. Install blocking around load bearing post (use pressure-treated lumber). Final width of blocking must be same width as inside of column.
|
|
3. Install blocking around center and top of post to match step 2. (Center blocking is optional.) Blocking may be attached to deck/soffit instead of post if necessary.
|
|
|
|
|
|
|
|
|
4. Trim shaft pieces at least 1/4" shorter than opening height (from step 1.) Trim ONLY from bottom - top end is marked.
|
|
5. If you are going to use screws, pre-drill/countersink all panels. See joint diagram on next page to determine which edge to pre-drill.
|
|
6. Lay 3 panels flat and apply adhesive to center joints. (Poly-urethane glue is recommended. Follow manufacturer's instructions.)
|
|
|
|
|
|
|
|
|
7. Assemble 3 panels, using E-Z lock joints.
|
|
8. If using screws assemble 3 panels together using coarse thread galvanized screws (deck screws).
|
|
9. Or if you are not using screws, finish nail 3 panels together.
|
|
|
|
|
|
|
|
|
10. Place the partially assembled (3 panels) column around post and blocking.
|
|
11. Apply adhesive to final panel and attach to shaft using E-Z Lock joints.
|
|
12. Screw or nail final panel in place.
|
|
|
|
|
|
|
|
|
13. Screw or nail column to blocking ONLY ON THE BOTTOM. Do not attach at center or top (to allow for expansion).
|
|
14. Apply adhesive to mitred ends of base moulding (9 1/4" tall) and assemble around bottom of column shaft.
|
|
15. Fasten joints on base with screws or nails.
|
|
|
|
|
|
|
|
|
16. The TOP of the shaft should NOT be fastened to the blocking, and there should be at least 1/4" gap to allow for expansion (see step 4).
|
|
17. There are TWO methods of attaching the cap. First apply adhesive to mitred ends of cap moulding (7 1/4" tall) and assemble around shaft. Screw or nail joints.
|
|
18. Option 1: attach cap to soffit with construction adhesive and toenail to soffit. DO NOT ATTACH cap to column shaft if the cap is flush with soffit (allows expansion*).
|
|
|
|
|
|
|
|
|
19. Option 2: leave 1/4" expansion room above cap, and pin-nail cap to the column. Be sure pin-nails DO NOT reach the blocking inside!!*
|
|
20. Caulk edges of base, cap, and nail or screw holes.
|
|
21. Clean surface of column with cleaner recommended by the paint manufacturer. Paint with 2 coats of acrylic latex paint.
