Measuring and Layout — FAQ
Can tile setters use these lasers outdoors?
Green lasers work outdoors up to 30 feet in shade, but bright sunlight requires a laser detector. For exterior tile work like patios, choose the KEZERS model with included receiver.
How often do these lasers need recalibration?
Professional tile setters should check calibration every 6 months or after significant drops. Most units hold calibration well, but verify against a known level before critical layout work.
What's the difference between 3x360° and 4x360°?
3x360° provides one horizontal and two vertical planes—enough for most tile work. 4x360° adds another vertical plane, useful for complex multi-room layouts but overkill for standard jobs.
Will the laser damage polished marble or glass tile?
No, laser light is low-power and safe for all tile surfaces. However, the beam reflects brightly off glossy surfaces—use this to your advantage for alignment, but wear safety glasses.
How do I clean thinset off the laser housing?
Let thinset dry completely, then brush off with a stiff brush. Avoid water around charging ports. IP54-rated units handle damp cloth cleaning, but never submerge.
Are these lasers accurate enough for large format 24x48 tile?
Yes, all tested lasers maintain ±1/9" accuracy at 30 feet, which translates to less than 1/32" error over a 4-foot tile—well within industry standards for large format installation.
