How To Create A Mitered Corners

Antico Elements` Stone Panels are designed to interlock on all sides to create a seamless look.
When it comes to corners you have two choices:

-Use our Outside Corners, which are very easy to install,

Using our corners


-Cut a panel in the middle and wrap it around the corner.

Using our Panels to create a corner

The instructions below are for the second option. Here is how you can cut and miter our panels to create a beautiful corner.

Tools needed: ( same as wood cutting tools )

• Measuring tape and pencil
• Table saw, circular saw, miter saw,  jigsaw, etc. You can use any blade designed for wood. Our material is very friendly.
• Nails or screws ( exterior grade if used outdoor)
• Hammer (or screwdriver/drill if using screws)
• Level
• Construction adhesive, E.G: Liquid Nails or PL.
• Safety Glasses

As mentioned above, the ideal saw for this particular project is a table saw BUT you can also use a circular saw with a straight edge.
The two important things to consider in order to create a professional-looking corner are:
1- You must miter the edges of the panels that will intersect at the corner and,
2- Both sides of the corners should come from the same panel so that the stones will line up.

Start by measuring where to cut the left side of the corner on a panel. Remember that you should always measure and mark the back of the panels.

Cut the left section so that the back edge will line up with the corner on the wall.
Cut the right section.
You should be left with a triangular piece.

Cut a panel in two.

The edges that will intersect at the corner need to be cut at 45 degrees.

The best way to secure the panels is by placing a few beads of construction adhesive ( E.g. Liquid Nails or PL ) on the back of each panel AND where the panels overlap and interlock, then use some screws.
Make sure to blow off all the dust from where the adhesive will be applied.

Apply adhesive.


Install the two halves of the panel to create the corner. Use construction adhesive behind the panels and at the corner joint. Secure with some long and coarse screws (we do not recommend using nails for this type of installation) making sure to minimize any gaps at the front edge of the corner. If you see that the two halves touch at the back of the joint, leaving a gap in the front, then you should adjust the angle of your blade/saw. You should use plenty of adhesive so that when the screws are installed you will see lots of adhesive squeeze out. Do not clean it off at this stage. Let it dry overnight and cut it when it hardened, along with any panel material that doesn’t line up with the other piece.

Glue and screw the two parts together.

Using a file or sandpaper smooth out the edges and excess material. If both sides of the corners come from the same panel you should have very little to sand.

Smooth out the edges

If necessary use some texture caulking (or caulking mixed with sand) to seal the gaps, to cover exposed material, and cover screw heads.
Our Touch-Up Kit can be used to cover the caulk and the sanded areas by matching every color of the stones. Click HERE to view the instructions on how to use our Touch-Up Kit.

Continue installing the rest of the panels, left to right, and repeat the above instruction for every corner.
For inside corners, you can use a similar procedure and by mitering the panels with the opposite 45-degree angle.
If installing multiple rows of panels remember to start the next row with a half panel to avoid lining up the vertical seams in the same place.
Install our Top Sills if necessary. They add a very nice finished look.

Install the rest of the panels.

Once all the parts are installed you may caulk all gaps to prevent water from sliding behind the panels.

Mitering an Inside Corner

Creating a mitered inside corner is a similar process to the outside corner. The main difference is that when making a miter cut on the face of the panels, you will remove some stone texture so many stones from the two pieces will not line up. This will require some more caulking and touch-up paint.

The ideal tool to create a mitered corner is a table saw, but a circular saw can do a good job as well.
Measure the size of the first piece on the panel and make the first cut.
The second piece of the panels will need to be cut again by flipping it upside down.

Miter-cut panels

Make sure to keep the two pieces of the same panel together, to reduce the mismatch of the stones.

Now, glue the two panels where they connect and use some screws to secure them.
Glue and screw them to your wall.

Glue and screw the pieces together

You will notice that at the intersections of the two pieces some of the stones will not line up, as they usually do in an outside mitered corner.

Fill in the gaps

The best way to resolve this issue is to blend in the stones from the left and right panels. Use a generous amount of caulking to fill in the gaps. As the caulking starts to dry, take a wet brush and gently dab on the caulk to remove its glossy look and to create some texture.
Once the caulk is try, use our Touch-up paint kits to add the proper color to each stone.


Congratulations! Your job is done and you can now enjoy an incredibly realistic stone look.
