Hello,
I bought this net to keep out mosquitos from our undercover outdoor area. It has super sticky glue on it but it peeled off the next day. I think it's a cement rendered wall (please correct me if I'm wrong). I tried drilling screws on the top but it's not going in. I also tried using a nail but it just bent (was thin but wasn't able to get through at all). I'm thinking there's a heavy iron bar behind it to hold up the balcony above.
Anyone have any ideas on how I can hang the net?
