Hi Angwick, thank you for your interest and question with Way Basics. All Way Basics products are made from zBoard paperboard which is paper based. The exterior layers of the board are treated with a water resistant material just like other finished wood veneers. If water gets on the zBoard surface, it will dry (though of course it's best if you wipe it up like all spills). You'll want to keep water away from the furniture's edges and corners where it's a little more vulnerable to moisture. We don't recommend using Way Basics outdoors because constant moisture and/or humidity will damage the material in the long run. Let me know if I can be of any further assistance. Have a great week ahead!
