I have a Sierra Designs tent that is about fifteen years old. The inside surfaces of both the floor and fly have become sticky. I stored the tent in a closet on the upper shelf the entire time where it is very warm much of the time, so I guess the stickiness is from the water repellent finish breaking down. If the finish breaking down is the cause of the stickiness that doesn’t mean the material has degraded in any way does it? I pulled on the material pretty hard, and it seems durable still. I washed the tent and fly a few times which did nothing. Is there anything I can do about the stickiness like spray something on the material that will cover up the stickiness and create another coating? I know I can replace the tent floor with silnylon or whatever, but the stickiness isn’t irritating enough for me to do that. Thanks for any replies.
