A last hazard is condensation. When humid air meets a cold surface, water will form on that surface. In a porous tile material, or a porous substrate, this moisture may interfere with proper bonding or rubber and epoxy type compounds. Whenever possible, the tile should be brought indoors overnight, allowing it to come up to room temperature. This eliminates one source of condensation.
Alcohol absorbs water and rapidly evaporates, taking the water along with it.
Cleaning with alcohol also helps to ensure a clean surface, for a good bond under any conditions. By following these simple precautions, you can be assured of a top-quality job every time. Moderate heat, moderate moisture, and getting your materials indoors, on-site before the work begins will prevent problems before they start. Remember, if you are not comfortable in the work area, it probably is not fit for good tile work, either.
