Is Your Tile Installation a Victim of Bad Lighting?
Critical lighting can make even the most skilled tile installation look flawed. The podcast Tile Happy Hour emphasizes that lighting can drastically alter the appearance of tile work, highlighting imperfections and casting unwanted shadows.
What is Critical Lighting?
Critical lighting occurs when light shines on tile surfaces at a sharp angle, almost parallel to the surface. This effect, often unintentional, exaggerates even minor inconsistencies in the tile work.
Why Does It Matter?
• Aesthetic Concerns: Critical lighting can create shadows that make the tile look uneven or poorly installed.
• Installation Disputes: Owners or inspectors unfamiliar with critical lighting effects may incorrectly blame the tile contractor and demand costly replacements.
What Can You Do?
1.Lighting Placement:
◦ Avoid "wall wash," "graze," or "cove" lighting that is close to the wall.
◦ Position lights at least 18 inches away from the tiled surface to minimize shadows.
2. Substrate Flatness: Ensure the substrate is flat before tiling to meet industry standards. Uneven substrates can worsen the effects of critical lighting.
3. Tile Selection: Be aware of tile tolerances for warpage and wedging. Select tiles that meet ANSI A137.1 standards for flatness.
4. Grout Joint Width: Wider grout joints can help to soften the effects of critical lighting.
5. Communication: Discuss lighting plans with the owner, architect, and designer before installation.
6. Pre-Installation Mock-Ups: Creating mock-ups with the intended lighting helps to visualize the end result and address potential issues early on.
7. Inspection: Inspect finished tile work from a normal viewing height and distance, using intended lighting. Avoid close-up inspections with flashlights.
