Clean the ground thoroughly to remove floating dust and debris, ensuring the surface is clean. Use measuring tools to locate the center of the room and draw a center crossline, ensuring the crosslines are vertically and equally divided.

Lay copper foil strips on the ground according to the specified dimensions to form a grid. Apply conductive adhesive at the intersections of copper foils to ensure conductivity. Use a megger to measure the resistance between adjacent copper foils—the resistance must be less than 10⁵Ω. For every 100 square meters, at least 4 grounding points must be reserved and connected to the ground wire. The copper foil strips must be straight, without curling or interruption, and the foil connected to the grounding terminal must be left with sufficient length.

Reliably connect the reserved copper foil grounding points to the earth ground to ensure the entire grounding grid is effectively grounded. For areas within 100 square meters, at least one grounding terminal shall be provided; for every additional 100 square meters, add 1-2 grounding terminals. When laying near the terminal, first extend the copper foil strip connecting the terminal and firmly connect it to the terminal.

Use a scraper to evenly apply conductive adhesive on both the ground surface and the copper foil grid. Allow it to dry for 20-30 minutes until it is no longer sticky to the touch. Apply conductive adhesive once on the underside (black side) of the anti-static mat as well. The adhesive application rate is approximately 0.33kg/m², using a triangular notched trowel.

Begin laying when the conductive adhesive is tacky but not fully dry. Start from the center and work outward piece by piece, tapping with a rubber mallet as you go to ensure full adhesion between the flooring and the ground. Maintain a gap of 1.5-2.0mm between flooring pieces. Ensure that the copper foil passes through the middle of the underside of each flooring piece and does not pass through the edges. After laying, roll the entire surface with a 70kg roller to ensure flatness and compaction.

After the flooring is laid, use a grooving machine to cut V-shaped or U-shaped grooves along the floor seams, with a groove width of approximately 4mm. Adjust the groove depth according to the floor thickness (for 2mm thick flooring, the groove depth should be 1.3-1.6mm). Place the welding rod into the groove and use a plastic welding gun (800-1000W) for thermoplastic welding, controlling the gun temperature between 400-500℃. The welding speed should be approximately 3.8 meters per minute, ensuring full and consistent weld seams without missed or weak welds. After the welding rod cools, use a scraper to trim the excess welding rod flush with the floor surface.

Clean the floor surface thoroughly after construction. Use a megger to test the surface-to-ground resistance of the flooring, which should be between 10⁵-10⁹Ω. Inspect the surface to ensure there are no bubbles, peeling, or weak welds. Apply an anti-static wax protective layer. The floor can be put into normal use after 48 hours at room temperature.
