How to Install Stacked-Stone Veneer

You don't need any professional building or construction knowledge to install stacked stone veneers. These ready-to-install pieces that resemble more complex stonework are light, attractive, and attach to myriad surfaces. This veneer is usually attached to a fireplace or the exterior of a home, but you can use them for a variety of needs. Install your own with these steps.

Step 1 - Estimate the Amount of Veneer Needed

First, measure the length and breadth of the surface where you will be installing the stacked-stone veneer. Next, depending on the dimension of one average-sized veneer stone, estimate the number of stones you will need for your project.

For the corners, measure the linear distance of the edge and divide it by the length or breadth of the veneer stone to get an appropriate estimate. Then, purchase the total number of stones that you have estimated.

Step 2 - Prepare the Surface

Next, prepare the surface where you will install the faux stone. Using a waterproof paper, cover the area. Then, cover the paper completely with metal lath.

Covering the Metal Lath

Cover the metal lath with scratch-coat mortar. This layer should be four to eight inches thick. Scratch the plaster with a hand rake while wet to create a better grip for the stacked veneer to adhere to. Let it dry for 48 hours.

Step 3 - Lay the Stacked Veneer

To make it easier to install, lay the stone pieces in your work area. Brush the backside of the stones to remove any dirt or debris. Arrange them according to the design you want, and move on to the next step.

Step 4 - Fix the Stacked Veneers

Apply a layer of mortar on the center of the veneer and then, using a trowel, taper it toward the edges. The layer should be three to four inches deep, as anything more than this will make the veneer slip and slide. Use tile adhesive for a longer-lasting bond.

Step 5 - Set the Veneer

Now, fix each veneer according to your planned design. Starting from the bottom, hold the veneer in place and press it down with uniform pressure.

Using More Mortar

Use a paintbrush to put mortar in the joints. Clean the excess mortar using a wire brush or scraper. For the corners, use a grinder to cut the veneer to fit. If your stacked-stone veneer ever chips or breaks, you can repair it with many of the same tools from this project.
