Through patented technology, AIRSTONE is light enough to glue directly onto drywall. This advancement simplifies installation, which saves time, money and headaches. These beautiful, individual stones have the look and feel of natural rock, yet are ultra-light weight and very durable. And AIRSTONE is so easy to install. Simply apply adhesive to the back of the stone and press to the wall. Now, anyone can add the beauty, texture and warmth of stone anywhere inside or outside the home. Note: For outdoor projects, AIRSTONE is ideal for adhering onto preexisting outdoor walls that are already weatherproof (i.e. brick, stucco, exposed concrete foundations, concrete block, siding, etc.). Also, AIRSTONE is also ideal for outdoor projects that are unattached to the home, such as outdoor kitchens, around pools, patios and porches, retaining walls, decks, columns, mailboxes, etc. AIRSTONE is not intended to be used as the shell of your home. Wood sheathing fastened to the frame of a house will settle, expand or contract, and if AIRSTONE is adhered directly onto that surface, adhesion problems or stone cracking may arise. Also note that AIRSTONE is not in itself a waterproof sheathing.
