Protect The Material
Clean and dry the board, then apply 303 Aerospace Protectant to your board according to the manufacturer’s directions. The 303 protectant will protect the material from damage caused by UV rays and exposure to the elements. It’s like sunscreen for your board. It protects it and keeps it strong and supple. 303 can be purchased on most retailers that sell inflatable kayaks, boards or boats.
If you have room, leave the board partially inflated (7 or 8 PSI) and store it in a basement or shed. If you have limited space, deflate the board and lay it flat under a bed or up on a rack. It’s easier on the seams if it’s not rolled up. If you have no space – don’t panic! Loosely fold or roll the board and store it out of the sunlight.
Regardless, store the board in a dry and cool place. Exposure to the elements will weaken the material over time. Ironically, sun and water are your board’s enemies when storing your board. UV rays, heat and mold are hazards that can cause the material of your board to deteriorate. If you must keep your board outside, cover it with a tarp in order to protect it from falling debris and exposure to the elements. And a word of warning, some rodents love to burrow into stored items and can cause massive damage when they do. So make that storage place a dry, cool, rodent-free area. Or get a cat to guard it.
