A: Hello. Thank you for reaching out to us. Sharpie Wet Erase Chalk Markers can be used on laminated paper, and the ink will wipe off with a damp cloth. If the laminated sheet is out in the rain for a few hours, the writing may start to wash away since the ink is water‑based. It won’t stain the laminate, but it likely won’t stay fully intact in wet weather. For outdoor use in rain, Sharpie Permant Markers would hold up better. If you have any more questions, please reach out to us via our Contact Us form on our website. We’re available Mon.-Fri. 9am - 5pm Eastern Time. Thank you! Sharpie® Consumer Care

A: Hello. Thank you for your question about the Sharpie 5-Pack Wet Erase Chalk Markers, Medium Point. These markers are designed for use on non-porous surfaces such as glass, mirrors, whiteboards, and traditional chalkboards with a smooth, sealed finish. If your painted chalkboard wall has a porous or matte surface, we do not recommend using wet erase markers, as the ink may absorb into the paint and be difficult to remove. For best results, use these markers only on a smooth, non-porous surface or test a small, inconspicuous area first to ensure easy cleanup. If you have any more questions, please reach out to us via our Contact Us form on our website. We’re available Mon.-Fri. 9am - 5pm Eastern Time. Thank you! Sharpie® Consumer Care
