General
Willki stone is a premium mechanically fastened stone veneer siding system that faithfully replicates the appearance of natural stone, without the high cost or complexity of traditional masonry. Made from lightweight concrete, each 32 x 9-inch panel covers an area of 2 square feet. Versatile and durable, Willki stone is suitable for both indoor and outdoor applications, offering a well-ventilated, sustainable architectural finish with a refined aesthetic.
Willki architectural stone panels combine exceptional beauty, quality, and innovation. Their integrated corners and reversible design significantly reduce installation waste, while the EziKi anchor key system creates a 0.5-inch air space behind the panels for optimal ventilation. Made with over 70% recycled materials, Willki Stone is a sustainable, durable, and versatile solution for any siding project.
Unlike natural stone, which requires mortar, adhesive, and the interventions of a mason, Willki panels are mechanically fastened directly to the wall using the EziKi anchoring system. This system supports each panel without adhesives and requires only a starter strip for the first row. The EziKi keys also create an air gap and make stacking the panels fast and clean, making installation accessible to skilled homeowners, siding installers, and general contractors.

Installation
Yes. The EziKi anchoring system was designed for a simple and efficient installation without needing masonry experience. Only 6 common tools are required.
The system is accessible to skilled homeowners as well as siding installers, carpenters, general contractors, and other building professionals.
Before starting, it is essential to consult the installation guide and videos to ensure the best results.
No. Willki panels are mechanically fastened thanks to the EziKi anchoring system, requiring no glue or mortar. Only 6 simple tools are needed.
Willki stone panels are suitable for both exterior and interior installations on most substrates, including plywood, concrete, and furring strips.
For interior installation, ensure the panels are mounted on a rigid surface—like ½-inch plywood or 7/16-inch OSB—securely screwed into wall studs to properly secure the anchor keys.
Yes. Willki panels, measuring 32 inches in length, can be installed on wooden or metal furring/strapping spaced 16 inches on center.
Willki panels can be installed on an ICF system only if the EziKi anchor keys are fastened into a solid structure (e.g., integrated studs or added wood strapping) and not directly into the foam. Since each ICF system varies, we strongly recommend contacting us to confirm the correct installation method for your project.
No. Willki panels are lightweight and do not require a footing, lintel, or foundation support. The system is self-supporting—each EziKi key bears the weight of the panel directly above it. To get started, you only need the starter strip to securely support the first row.
This system is therefore ideal for renovation projects without an existing foundation or footing.
It is recommended to add 4–5% to your total surface area to account for cuts and fitting adjustments. Thanks to the reversible design of Willki panels, waste is kept to a minimum compared to other systems.
Willki uses multiple panel models, all of which are reversible, to eliminate visible repetition. In addition, each panel features a painted accent integrated into the concrete matrix, giving depth and uniqueness to every installation.
Two anchor keys must be installed to secure each panel. One anchor key only can be used if the panel length is less than 10 inches (254 mm).
No. The ends of Willki panels are textured to mimic the look of a stone corner. Simply stagger the panels as illustrated.
For a detailed explanation, watch our corner installation video.
Simply stagger the panels as shown. For best results, use interior panels marked with an “I” in the groove end, ensuring a clean and tight joint.
For detailed guidance, refer to our corner installation video.
Yes, to meet building code requirements, a weather-resistant barrier (WRB) meeting ASTM E 2556/E 2556M standards is necessary for exterior applications.
For the final row, you may need to cut the panels lengthwise to fit the height. Since an EziKi key cannot be installed at the top of a cut panel, simply screw the panel through one of the stone joints. Use the included spacers to maintain the air gap behind the panel.
See our last row installation video for step-by-step instructions.
Yes. Being made of lightweight concrete, the panels are easily cut using a hand grinder, miter saw, or table circular saw with a diamond blade.
Yes. Willki panels are made of fire-resistant concrete, making them safe for use around indoor fireplaces.
However, always follow the fireplace manufacturer’s clearance guidelines and local fire safety regulations before installation.
