Our 90º corner panels are designed to work together horizontally and stack vertically. Each corner panel provides 23 inches of vertical coverage and will fit seamlessly around a 17 inch square post. If your post is less than 17 inches, furring strips can be used to extend a smaller post out to 17 inches before attaching the panels. If your post is 8 inches or smaller, we recommend our pillar panels.
The 90º outside corner piece eliminates the need to miter panels when your installation demands a transition into another wall. This piece also creates the necessary offset pattern throughout the install. The positive shiplap edge along the left side of the piece allows panels joining from the left to slide under the corner. The negative shiplap edge on the right side provides a reliable connection to any panel installed to its right.
Designed to fit seamlessly on top of four 90º corner panels, the GenStone Column Cap is 23 inches square and provides a modern but rustic finish to your column. Each cap can be easily attached to the column using adhesive and deck screws. Fastener holes can be concealed with color match caulking and paint kit.

Simply Measure, Cut and Attach
The GenStone system was designed for the average do-it-yourselfer. GenStone projects require only ordinary hand tools and most projects can be completed over the course of a couple of hours. Each panel can be cut to size easily with a hand or power saw and attached with screws and adhesive.
More Attention to Detail
Every GenStone panel is cast from real stone or tumbled brick to ensure authentic shapes and texture. All panels receive 12 coats of meticulously hand painted details, which results in little to no repetition.

We offer two types of caulking, Big Stretch white caulking (one tube every 100 SQFT) and Exact Match caulking (one tube every 400 SQFT). Big Stretch is used along the shiplap edges of the stacked stone panels and in the areas where our brick panels connect. It is also applied where ledgers meet the substrate and where panels connect to ledgers and trim.
Exact color can be tinted with a paint kit and is used to conceal visible fastener holes in the panels, ledgers and trim.
One paint kit for every 400 SQFT of GenStone installed is recommended for all exterior and interior projects. Paint must be used on all raw exposed material revealed by a cut as exposed raw material will yellow in the sun if left unpainted. Paint is also used to perfectly blend caulking used to conceal fastener holes.
We also suggest purchasing one dedicated paint kit for every one tube of Exact Color caulking. This dedicated paint kit will be used to tint the caulking.
For exterior installations over wood and some stucco substrates, 1.625" non corrosive deck screws should be used to attach the panels while 2.50" non corrosive deck screws are recommended for ledgers. For concrete, brick and most stucco substrates, Tapcon concrete anchors are the best fastener choice.
Drywall screws can be substituted for deck screws for all interior installations over drywall. Tapcon screws should be used for interior projects over brick, concrete or other rigid substrates.
