Why Does My Wargaming Mat Smell and How to Fix It

Quick answer

A new wargaming mat's smell is usually harmless outgassing from manufacturing. Air it out for 24–48 hours or wipe it with a mild soap solution; if the odor persists after deep cleaning, consider returning it.

Why the smell happens

New play mats are printed on materials like heavy-weight matte banner or neoprene, then rolled and sealed in plastic for shipping. The trapped air allows volatile compounds from inks and adhesives to concentrate, which is why the smell is strongest when you first unroll the mat.

This outgassing is normal and not a sign of a defective product. It usually fades within a few days once the mat is exposed to fresh air.

If the odor remains strong after a week or returns after cleaning, it may indicate a material issue or a reaction with your storage area.

Diagnose and fix the smell

• Symptom: A strong chemical or rubbery smell when you unroll the mat for the first time.
• Likely cause: Outgassing from inks and adhesives trapped in the packaging during shipping.
• Corrective action: Unroll the mat in a well-ventilated area and let it air out for 24–48 hours. If the smell persists, wipe the surface with a soft cloth dampened with mild soap and water, then let it dry completely before storing. Test the mat in a small corner first to ensure the cleaning method does not affect the print.
• Stop or choose another option: If the smell is still strong after a week of airing and cleaning, or if it worsens, the mat may have a material defect. Contact the seller for a replacement or return.
