Zig Posterman waterproof markers feature an opaque liquid chalk ink that will not wash off with just water. They are perfect for lettering and designs that may be exposed to moisture or left outside. Use these markers on your chalkboard labels, outdoor signs, black and whiteboards, store windows, cars, and much more.
The markers’ waterproof ink means it will not wash off with just water. To clean the ink, use a cleaner with ammonia, like Windex or kitchen cleaner. Allow the surface to fully dry before reapplying markers.
Waterproof markers are easy to use. Shake the marker well before opening. Prime the marker by holding it vertically against a scrap material and pushing down. This will depress the tip into the barrel, allowing it fill. Hold for approximately 10 seconds and release. It may take several tries to allow the ink to flow. Once filled, the tip may need to be refilled occasionally. Use extra care not to prime the marker at an angle; only push straight down on the marker.
