Faux River Rock Panels Installation

Antico Elements` Rock Panels are designed to interlock on all sides to create a seamless look. They are designed for Indoor and Outdoor uses. Even though the installation is very simple, make sure to read the instructions in order to avoid problems and gaps.

River Rock PanelsBefore installations:
Always try to keep the panels leveled. The walls should be dry and free of dust. We strongly suggest the use of the fasteners and plenty of adhesive where the panels and lips overlap.
Important: When using the product outdoor make sure to store the panels in a cool area before installing them. If they are left in a hot place it may cause a small degree of shrinkage when the temperature outside drops.

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 and masonry screws for brick, concrete, etc)
• Nail set
• Hammer (or screwdriver/drill if using screws)
• Level
• Framing square
• Chalk line
• Construction adhesive, E.G: Liquid Nails, PL, etc.
• Safety Glasses

Our products can be installed indoors and Outdoor, directly over framing, drywall, brick, or concrete.
-For indoors all you need is adhesive and wood screws.
-For outdoor you might need an outdoor-grade adhesive and galvanized screws. Some caulking may be needed.
-For brick, concrete, cinder blocks, and similar you will need masonry screws, like “Tapcons”.

Installing parts:
Note: Your order will contain a mix of panels A and B. These have the middle stones arranged with two different patterns to avoid a repetition in the panels. Make sure to mix them when installing them.
It is always a good idea to temporarily layout the panels around the project to plan which / how panels will be cut and which will not.

Position The Inside Corners
Prepare The Outside Corner

In your project, you may have inside (e.g. corners in a square room) or outside corners ( e.g the corners in the image above) to deal with. For the outside ones, we have Outside Corners already made. For inside corners, you will need to use the Grouted Panel and Individual Rocks, described in more detail below.
If you plan to use our corners, start by installing them TEMPORARILY before the panels, making sure they are perpendicular to the floor. For now, just use a couple of nails/screws and NO adhesive.

We recommend that you install the panels from left to right. For better results mark some horizontal chalk lines on the wall to keep your panels leveled.
Position the panels so that the horizontal 48″ lip is at the top and the horizontal notch at the bottom.
If you start the project by butting the first panel against another wall, the left side of the first panel should be trimmed, removing the protruding stones and creating a straight edge.
Apply a few lines of adhesive in the back and ( important ) where the panels overlap / interlock and fasten the panel to the wall using screws. We suggest using at least 8-10 screws per panel.

If you install the screws below a stone, rather than in the middle, it will be easier to conceal them. To completely conceal the screw heads you can apply any color caulk and use our Touch-Up Kit to match the stone colors.

First Row
Install The First Row Of Panels

Continue with the rest of the panels of the first row.
In most cases, when reaching an inside or outside corner, you will have a gap between the last panel and the corner. A full panel will be either too short or too long. For this reason, we have created a Grouted Panel and Individual Rocks.
In some cases like fireplaces, one corner and one panel will be longer than the face of the fireplace. In this case, we suggest miter-cutting the right side of the panel to create the turn or place the full panel in the middle and create left and right corners with our Grouted Panel and Individual Rocks.

Cut a section of the Grouted Panel to fit between the last Rock panel and the corner.

Please consider that the grouted panel has a tongue-and-groove system. When cutting the grouted panel take a minute to choose which side to use.

Once the grouted panel is installed you may start installing the Individual Rocks on top of it.

If you need to install multiple rows the steps are the same as above.



We do not provide the pre-made inside corners. Instead, we suggest the use of our Grouted Panel and Individual Rocks. Even if we had the pre-made corners you will most likely need a piece of the grouted panels and rock.

Spaces between panels and corners
Spaces between panels and corners

Start by filling the empty spaces between panels and corners with the Grouted Panel. These pieces can be mitered to align better at the corners.

Once the gaps between panels and corners are filled with parts of the grouted panels and they are properly caulked to prevent any water intrusions you may begin arranging the Individual Rocks.

You may also use our Concrete or other color sills to cap the top edges of the panels or use them as an end piece (vertically)

Installing The Top Sill


If you do not plan to install the Rock Panels all the way to the ceiling you may use our Trim Sill – Ledge Trim to cap the top edge of the panels. These trim can also be used on the side of the panel, in case you decide to stop the panel in the middle of a wall.
Install the Top Sills in the correct direction making sure to locate the unfinished edge and place it against the wall. The bottom front edge should be finished. If the sill is not touching the wall it should be turned around.
To create a better seam between two sills, the sills should be mitered where they meet at the corners, as you would do with a picture frame.

In most cases caulking the seams should not be needed but you can apply any exterior grade caulk and use our Touch-Up Kit to match the stone colors.
