Jason, We sell EVA foam sheets that would fit your needs, but they are not smooth. Our sheets have raised dots. If you are interested in a free sample, please visit our website at
www.deckdots.com. If our product does not meet your needs you can visit
http://hydroturf.com/ They sell 40"x62" sheets for 59.95 + 20.00 for the self adhesive backing. Good luck
