[## How Rock Is Sold At Mid Valley Rock, natural stone arrives on pallets and is sold by weight. A Weighmaster records the weight of your purchase less the pallet, and we quote prices by phone or at the yard instead of publishing them. Read the guide](https://midvalleyrock.com/rock-talk/how-rock-is-sold/)[## Flagstone Thickness Guide Thinner flagstone, around 1 1/4 inch, should be hard set with mortar over concrete. Flagstone 1 1/2 to 2 inches thick is strong enough to soft set on sand and decomposed granite, which makes it the usual pick for small patios and walkways. Read the guide](https://midvalleyrock.com/rock-talk/flagstone-thickness-guide/)[## How Much Flagstone Do I Need? Measure the area in square feet, add a little extra for cuts and fitting, and bring the number to our yard. Because flagstone is sold by weight and coverage changes with thickness and density, our staff convert your square footage into a weight for your quote. Read the guide](https://midvalleyrock.com/rock-talk/how-much-flagstone-do-i-need/)[## Soft-Set vs Hard-Set Flagstone Hard-set flagstone is mortared over a concrete slab for a permanent surface. Soft-set flagstone rests on a compacted, water-permeable base with sand and decomposed granite in the joints, and it needs stone 1 1/2 to 2 inches thick. Read the guide](https://midvalleyrock.com/rock-talk/soft-set-vs-hard-set/)[## How to Seal Flagstone Seal flagstone only when it is completely dry: wash it, let it dry 5 to 10 days with sprinklers off, then apply two coats in the cool early morning, the first north to south and the second east to west. Read the guide](https://midvalleyrock.com/rock-talk/sealing-flagstone/)[## Wet Look vs Natural Flagstone If you love the deeper color your flagstone shows when it rains, a color-enhancing sealer can give it that wet look, and resealing over time keeps it. If you prefer the soft, dry color, leave it natural or use a matte sealer. Read the guide](https://midvalleyrock.com/rock-talk/wet-look-vs-natural/)[## Installing Flagstone with Gator Dust Gator Dust must have a gravel base 2 to 3 inches thick, and Anna recommends 1 inch of sand over the gravel. Set the flagstone, sweep Gator Dust into the joints, and follow Alliance's instructions for wetting it.

Some stone does not hold up to pool chemicals or constant exposure to water, so tell our staff how the rock will be used and we will guide you to a suitable stone. Read the guide](https://midvalleyrock.com/rock-talk/choosing-stone-for-water-features/)[## Can You Mix Different Stone Types? Yes. You do not have to use one stone for your whole job, and different kinds of stone often complement each other and make a project more unique. Our staff will suggest combinations that work and tell you which ones we would not recommend. Read the guide](https://midvalleyrock.com/rock-talk/mixing-stone-types/)[## Planning Your Visit to the Yard Bring tape-measured square footage, your landscape plan if you have one, and a photo of your house, and arrive at least 45 minutes before closing. With those, our staff can suggest stone and give you a quote for your choice. Read the guide](https://midvalleyrock.com/rock-talk/planning-your-yard-visit/)[## Boulder Sizes and Weights Mid Valley Rock's boulders range from about 6 to 8 inches across, weighing roughly 30 pounds, up to about 4 by 4 feet, weighing roughly 4,000 pounds. Small ones can be moved with a rented dolly; the largest need delivery by flatbed and forklift and often a crane. Read the guide](https://midvalleyrock.com/rock-talk/boulder-sizes-and-weights/)[## Flagstone vs Pavers Both make excellent patios and walkways. Flagstone is natural stone with irregular shapes and one-of-a-kind color, while pavers are manufactured units with uniform sizes and a consistent, orderly pattern; the right choice depends on the look you want and how the space is used.
