GenStone color match caulking is used to create a secure connection along the shiplap edge of the panels and corners. It is also applied to the contact point between ledgers and panels. Most importantly, the color match caulking makes concealing visible screw holes in the face of the panels and ledgers quick and easy. Simply fill the void with caulking, wait for it to dry and then blend the area with a GenStone paint kit to make the fastener hole disappear.
We recommend one tube of caulking for every 100 SQFT of GenStone you install.
