Rosetta Grand Flagstone
Natural Sophistication

The look of large natural flagstone without the hassle of fitting all the different pieces together. Rosetta Grand Flagstone is the perfect solution for creating a natural look in your outdoor living space. It maintains the attractive texture and scale of large natural flagstone but can be laid in an easy-to-install pattern. Each slab’s thickness is consistent, making for a quick install and is perfect for patios, pathways, pool decks, outdoor kitchens and more.

When installing Grand Flagstone, make sure to include a 2-5mm gap between each slab. This will provide enough room for the jointing sand and make installation easier.
