: Use a white laminate or light-colored plywood base. Opaque or dark materials will absorb the light and ruin the effect.
: The foundation is everything. Ensure your subfloor is rock-solid and level. Use shims to prevent water from pooling and test for "rocking" before securing the base with expansion foam or silicone.
For most homeowners, "Pure Onyx" refers to the solid-surface panels from The Onyx Collection . These are prized for being easier to install than traditional tile. 1. Preparation & Layout pure onyx install
: Most panels are installed over standard 1/2" sheetrock treated with a coat of latex primer. You don't need to mud the seams or fill screw holes, but the surface must be clean and dust-free.
If you are installing natural, translucent onyx stone (often used for backlit bars or feature walls), the process is significantly more technical. : Use a white laminate or light-colored plywood base
: Before applying any adhesive, "dry fit" your panels. Back panels go in first, followed by side panels. Check for "plumb" (perfectly vertical) walls and scribe the edges using wood-cutting tools if your walls are bowed. 2. The Adhesion Process
: Apply the manufacturer’s adhesive silicone in 2-inch diameter rings (about 3/8" thick) spaced roughly 8 inches apart. Run a continuous bead about 1 inch from the perimeter to support the edges. Ensure your subfloor is rock-solid and level
: To avoid seeing "hot spots" (individual LED dots), you must create a cavity between the lights and the stone. Pros often use a 12mm clear acrylic sheet as a support layer to diffuse the light evenly.
: Once you press the panel to the wall, briefly pull it slightly away. This lets air interact with the silicone to improve the curing process before you press it back firmly into place. 3. Sealing for Waterproofing
Because "Pure Onyx" often refers to both the popular bathroom wall systems and high-end natural stone slabs, this guide covers the critical steps for a successful installation for both. Part 1: Installing Onyx Collection Bathroom Panels
