That's what we thought until we completed a 6x14-ft. entry patio in less than one day. This same project would have taken at least two weekends at the very least if we had poured a slab, waited for it to cure and then set each stone in a mortar bed. We also escaped without a single sore muscle or scraped knee. All six colors are used in the prefab patio panels, though you can also order specific color combinations. Square and rectangular slate tiles are adhered to the polystyrene with a flexible waterproof adhesive.
Durability is also part of the package.
Its thickness also provides a cushioning effect beneath the hard slate. Either way, panels are shipped directly to your home along with all the necessary supplies, including rubber spacers, foam backer rod, tubes of sealant and installation instructions. Your first step is to build a perimeter border to establish the size and shape of the patio. We used pressure-treated 2x4s set on edge, but 4x4s, plastic edging or brick pavers will work too. To build a 2x4 border, start by screwing together the four boards to form a perimeter frame.
