All About Stone Veneer
Thanks to lightweight veneers, it gets easier by the day to dress up a room or the whole darn house
Mother Nature has been producing granite and river rock for millions of years, of course. And mankind has been experimenting with stone veneers since the Romans built the Coliseum. If you're not an emperor, though, adding such geologic wonders to your home's decor has always been a challenge. It once cost a small fortune to truck a few tons of rock to your front door. Installing it was labor-intensive. And, well, the DIY-friendly faux stone just didn't measure up to the real thing.
That's all changing, however. Natural stone can now be carved into thin slices that are light enough to transport almost anywhere. And cast, or faux, stone has received a major infusion of authenticity. Today, it's made from a concrete mixture that features a dozen or more pigments seamlessly blended together in molds produced from the contours of real stones. And by vibrating those molds during the manufacturing process, the final product is infused with color that runs throughout.
As a result, stone veneers are rapidly making their way into virtually every room in the house, in a sweeping range of styles. You'll find them popping up outdoors, too. From backyard kitchens to bathroom walls, rustic fireplaces to stylish dining rooms, lightweight veneers are remarkably versatile. Just take a look. You're bound to find something that suits your taste.

What's it made of?
If Mother Nature didn't create it, the stone is a mixture of portland cement, lightweight aggregate (such as pumice), and iron-oxide pigments shaped in a mold.
What's it cost?
Real stone can range from $7 to $19 per square foot. Cast stone will cost you $1.25 to $8. Expect to pay about $10 or more per square foot either way for a pro installation.

If you've laid tile, you can handle most projects. Installing veneer on the exterior of a house is best left to a reputable expert.
How much care does it need?
A light dusting or a rinse with a hose is often enough. If need be, nicks in cast stone can be retouched with a color repair kit. To remove crystalline deposits, known as efflorescence, from cast stone, use a mild mixture of 5 parts water to 1 part white vinegar.
At first glance, it's not easy to spot the impostor in the pictures above. (Hint: Look at the one on the left.) But there are a few key differences between cast stone and its natural-born relative. Artificial stone is less expensive, significantly lighter, and quicker to install. But one good bump can reveal its weakness and spoil the facade. To be safe, keep a few extra pieces of veneer handy in the basement. Natural stone is simply that—rock that has been cut into a veneer ¾ inch to 1¼ inches thick and has all the shading, color, and flaws that come with eons of geologic pressure. It's more durable and more versatile, but it also costs more to purchase and takes longer to install.

Veneer comes in corner pieces and flat pieces. The corner pieces are sold by the linear foot, the flat ones by the square foot. Using the dimensions of the project space, figure out how much of each item you'll need. Be sure to subtract the areas filled by doors, windows, fireplaces, etc.
Before you begin, check with a building inspector about local code requirements.
Prior to installing the stone, map out a design on the ground. Be sure to choose veneer from different boxes to vary the shapes and colors.
Install the corner pieces first, then work your way down from the top. This will prevent mortar from staining the stones below.
If you discover a mortar drip on one of the stones, wait for it to dry before brushing it off with a whisk broom. Smears can permanently stain the stone.
When possible, hide edges that you trimmed by pointing them up or down, above or below eye level.
Besides sealing out moisture and insects, grout helps set the tone for a project. It all depends on how much, if any, you use. Consider these options
The stones are placed roughly a finger's width apart, leaving space for the grout to be piped between them. When the grout begins to dry, the joint is "raked" to create a concave look with consistent depth.

For a more rustic look, the grout is piped until it inches above the face of the stone. At job's end, the joints are wider and less uniform.

Layering the veneer like puzzle pieces eliminates the need for grout. Keep in mind, though, that this also takes away a line of defense against the elements.

Unless you're a professional mason, it's wise to heed the manufacturer's suggestions. In general, type N mortar and the stickier type S give you the flexibility to place and adjust the veneer, but various additives can influence the set time, the water resistance, and the bond strength between the mortar, the stone, and the substrate. While considering the choices, inquire about color options, too. Many suppliers offer pigments that help you shade the mix to match the stone.
