I bought some industrial strength low profile velcro in order to make wall mounting stations for a fan. The fan (about 8 lbs) slides onto hooks screwed into 24"x7" pieces of 1/2 inch thick MDF. The loop side of the velcro is stuck to the back of the MDF in two ~23 inch strips at the top and bottom, and the hook side is stuck to the wall.
I put these up in two places and let the adhesive sit for 24 hours before using them. On one, the MDF-adhesive bond started failing after about 12 hours of holding the fan, and on the other, the MDF-adhesive bond started failing after about of week of holding the fan intermittently.
How can I prevent the adhesive from peeling off the MDF? Would super glue stick better?
