The Mighty Marker TM-82 Tile Marker is the specialty paint pen contractors trust when ordinary art supplies or grease pencils wash away. Its high-solid, water-resistant paint bonds to glazed ceramic and glass tile even under the high-pressure water of a wet saw or water-jet cutter, so layout lines stay intact through every rip, plunge, and miter cut. A fine 1.2 mm bullet tip delivers crisp, vibrant marks perfect for tight grout-line templates, while the valve-action mechanism keeps paint fresh and prevents dry-out if the cap is misplaced. When the job is done, spray an ammonia-based glass cleaner and wipe. The no-ghost formula removes completely, leaving surfaces spotless for grout, sealant, or finish coats. Housed in a compact 4 ml barrel with a sturdy clip-cap, the TM-82 travels effortlessly from workshop to jobsite. Made in the USA, it is engineered for the rigors of construction, home improvement, and tile-cutting applications, marking accurately, resisting coolant, and cleaning off without a trace.
