Measuring and Marking:
Ifyouplantouseacircularorhandsaw,itisbesttomeasureandmarkontheback,atsideofthepanel.Usealevelorotherstraight
edge, pencil or marker, and a tape measure to mark the cut line. If you plan to cut using a table saw, it would be better to mark a
pointonthepanelsurfaceandusetheatsidedownonthetable.Sealallcutedgeswithcolormatchedcaulkortouchuppaintto
protect from UV.
Cutting and Trimming:
Afterfollowingthemarkinginstructionsaboveyouarenowreadytocut.Touseacircular
saw, cutting along the mark on the back, you will need to protect the face of the panel as
youholditinplaceonasmoothattable.Placingthepanelatsidedownonthesawworks

such as hose bibs, electrical plates, or lights mark from the back and then cut out using a
keyholesaw,jigsaw,oraholesawonadrill.BecauseGenStoneproductsarehandmadeand
go through a manufacturing process there are occasionally minor blemishes at the edge of
thepanels.Theseareeasilycorrectedbyslighttrimmingwithautilityknifeorbysanding.
Someinstallationsmayrequireanewnegativeshiplapedgebecutintoaside.Thiscanbe
done with a table saw, a router or router table, or if neither of these is available a circular saw
preferablywithaguide.Useapaneltodeterminetheheight(onatablesaw)ordepth(with

of material out of the corner. A router or router table can also be used to remove this material
leaving the new negative ship lap edge.
Application and Prep:
GenStone products are
designed to be applied to a
variety of substrates. These
include concrete wall, CMU
(cinder block), brick, hard
stucco, cement backer boards,
OSB, plywood, at board
siding,anddrywall.Regardless
of the substrate, the surface
should be clean and free of
debris or loose pieces. If your
application includes adhesive on the back side make sure that the substrate is free from
residues, oils, or any other substance that would cause poor bonding. It is imperative to use
ahighqualityexteriorgradescrewwithadequatecompositionorcoatingtoattachthepanel.
GenStonepanelshavebothapositiveshiplapedgeandanegativeshiplapedge.Thepositive
shiplapedgeistheedgethatprotrudesfromthepanelformingalip.Thenegativeshiplapedgeisanundercutinthepanelforming

It’s best not to sit panels in the hot, direct sunlight for longer periods of time prior to installation as this may cause expansion.
