    Q:Can you use this product for the corners on an outdoor hot tub when replacing the skirting/cabinet?
    by|Apr 3, 2024
    1 Answer
    Answer This Question

    A:  The corner will attach to any flat surface that is relatively close to a 90º corner. There is some flex in the panel as you fasten it to the substrate.

        Q:Are these the same as the GEN STONE Desert Sunrise Pillar Panels. Can I use these to wrap a nominal size 8 x 8 post 36" high
        by|Jan 17, 2024
        1 Answer
        Answer This Question

        A:  No, these will fit around a 17 inch column. We just redesigned our pillar panels to 24" rather than 48" tall as too many were breaking in transit. The new panels are available, just not on all retail sites yet.

          Looks great years later
          Installed this on front of house 10 plus years ago and still looks great. Front of house gets a a lot of sun and very minimal fading.

          Awesome to hear, thank you for being a brand advocate and taking the time to share your positive experience with our product, we appreciate it! We have a great use and care guide on our website that includes instructions on how to apply a water based concrete sealer that will bring the panels back to the exact same look as the day they were installed.

              One simple way to get that stacked rock look
              We bought an order of Genstone panels and pieces to accent our Alaska cabin. We just put the panels on the bar inside, and it made all the difference

                Very easy to deal with.
                The panels and corners are very easy to cut and finish. Installation is a piece of cake. To hide the screws on the front panels is very easy to do it. You don't have to be a pro on construction. Price is very affordable compare to real stones. I'm already planning some other projects with Genstone.

                Wow! Northern Slate was a great choice to complement the steel appliances. You must have made quite a few cuts, you did an incredible job with the finishing overall, wrapping the stone around each void is done perfectly. Thank you for sharing and for writing a review, looking forward to working with you on your next GenStone project.

                  We Love our GenStone Fireplace Surround!
                  We wanted to let you know how happy we are with the GenStone fireplace project. My wife and I are over 70 years old. Relatives and friends who’ve seen it are astounded at its authentic appearance and the fact we did the project ourselves in less than a day. After researching the dizzying choices of stone fireplace surround solutions we chose your GenStone Vanilla Bean product for many reasons: Installs Directly Over Drywall No Need for Mortar Affordability No 3rd Party Installers Suitability for, and ease of, DIY installation Attractiveness Authentic Appearance Durability Your representative followed up on my initial inquiry from your website and was exceptionally friendly, helpful, and knowledgeable. He answered every one of my questions and assured me the product was ideal for DIY installations like ours. After ordering samples we chose the Vanilla Bean color. He specified the exact amount of product needed and described how to cut the special tabs on the shorter pieces. He also explained how to stagger the edge pieces for a more professional look. Our shipment arrived in perfect condition, well-packaged to prevent damage. After practicing a few cuts with various saws on the sample product, I decided to use my Japanese pull saw for all installation cuts. Its thin blade and fine teeth cut straight and true, leaving no unsightly rough edges. I used my Dremel to rout out the end pieces to fit perfectly around our mantel. The project took about 8 hours to complete and was fun to do. What a dramatic improvement GenStone made to our living room!

                    We stuccoed our home a year ago and had some pop-outs added so we could add some stone. It took us a year to finally decide what product to use. We used the GenStone Northern Slate for our home and absolutely love it! We have had numerous neighbors stop and tell us that it looked beautiful. We couldn’t be happier!

                    Hi Roclynn, thank you so much for taking the time to share your project and review, it turned out amazing! Northern Slate was a great choice for your home, it looks perfect with the dark stucco. Thanks again and hope to work with you again in the future.

                      Love it! Couldn't be happier!
                      We used the Coffee Stacked Stone to cover the old ugly concrete foundation around our house and we couldn't be happier! It was easy to install and super easy to handle. The measuring tool on the website was perfect (except I forgot to add the corner pieces but a quick call to customer service remedied that situation and we had them a few days later and were able to complete the project quickly!) I highly recommend this product and this company - everything was first rate and top quality.

                        Homeowner Installation
                        This product is very user friendly, light weight, and looks like real slate/shale/sandstone. I prepared the wall, by removing the original siding, placing tyvek paper and taping the seams for about one hour. The next day, I installed the Genstone product (about 4 hours) to the porch walls with just 1 5/8" decking star screws and placing the sealant in the requested areas. See for yourself in the photos. Any homeowner can install this!

                          So Easy - Instant Upgrade!
                          I wanted to spruce up the kid’s playhouse and so I only needed a couple of sheets of the stone. It made it look instantly better. I just used a backsaw to cut the pieces- no special tools needed. I’ll attach a before and after so you can see.

                          Hi Amanda, thanks so much for sharing your playhouse project with us! This was the first time we've seen GenStone used in this way and now that you've shared these pictures, I'm sure it won't be the last time. Everyone on our team loves the playhouse, thanks again.
