So What's Different About Installing ESD Tile?
The first line of defense in preventing this damage is to install static protective permanent flooring, and require employees to wear conductive heel grounding-straps or footwear. This system minimizes static build-up on personnel, and carries any charges to electrical ground through the floor.
Installing ESD tile is similar to installing vinyl composition tile (VCT). However, the differences are important enough that they may affect the tile's electrical and physical performance.
With reactive-epoxy adhesive, it's important to finish laying tiles over any exposed adhesive. If the adhesive cures and you later apply a fresh coat, the hardened trowel ridges of the previous coat will cause any tiles laid over the same area to lie unevenly and adhere poorly.
Drop each tile into place and press evenly and firmly. If any adhesive oozes up between the tiles or onto the surface, wipe it off immediately with a soft, clean rag and warm, soapy water. If allowed to cure, the adhesive will be hard to remove. Its black color can ruin the appearance of light-colored tiles.
Roll the finished section in two directions. After the tile has set for 20-30 minutes, roll the section twice with a 150-pound roller, first in one direction, and then in a perpendicular direction.
Lift an installed tile periodically to check the adhesive coverage. The goal is to cover 100% of the tile back with the adhesive. When the tile back is completely black, you know the spread rate is about right, and that the rolling was done at the right time. Proper adhesive coverage affects both the bond and the floor's electrical conductivity. This quality-control step is essential to successful installation.
If installed with reasonable care, and according to the manufacturer's instructions, the finished floor will do its job of reducing static and provide an attractive, durable surface.
