Guides & Downloads
The 90° inside corner piece is unique to the GenStone system. This panel eliminates the need to miter panels when you need to transition through an inside corner. Like the outside corner panel, this piece also creates the necessary offset pattern throughout the install. The positive shiplap edge runs along the left side of the panel and the negative shiplap edge follows the right side. Each shiplap is designed to provide a tight connection to panels joined to its right and left.

ABOUT GENSTONE! Read LessRead less about I HAD NEVER SEEN THIS PRODUCT BEFORE,








! I ordered a sample and once we had our hands on it, we were sold! It has now been installed and it looks absolutely beautiful! I cannot believe this is the same house we have lived in for 30 years! I will recommend this to anyone looking for an exterior upgrade to their home! Read LessRead less about It was time for an exterior remodel of


it a little bit then slowly trim snd file it to fit. I used a trim rasp to make small adjustments and it worked great.
I used PL premium on the back of all the panels. Since my application was on the exterior of the house but inside the porch the panels wouldn’t be getting any rain water so I did not use waterproofing silicone in every joint. I used exterior 1 5/8” screws to fasten the positive shiplap and used 1 5/8 exterior trim screws to fasten the lower area of the panel thru the face. I purchased 2 kits of color matched caulk in anticipation of having to fill in the screw holes when installed through the face but it was not necessary. I would run the trim screws in the mortar joints on a diagonal and place them in spots where you cannon see them. The bottom panels closest to the floor would get trim screws going upward in a mortar joint and as the rows got higher I would start running the trim screws downward in the mortar joints. You literally can’t even find them if you look for them.
Overall I was very happy with the product and install process. I added 10% to my estimated square footage then added a few more panels. I ended up having 1 full panel leftover after install. I would definitely recommend this product and would use it again. I cannot report the products durability because it’s only been up for a few weeks snd it is not exposed to the weather.
