Ive used a hairdryer to heat up the adhesive. I know it is optional but I would highly recommend it. Also use the included thumbtacks to secure it specifically on each end of the door because that is where it will start peeling off over time.
I am very impressed with this product.
It is very durable and worked out well. I'm glad that I purchased this product as it really has fit the bill for what I needed it for.
I have had mine installed for about a month and a half and I haven't had any issues with it, it's still firmly stuck to the door, I didn't use the tacks that were included either, The one in my bedroom doesn't have any clearance issues, but the people that poured my garage slab made it very uneven and the one that's installed out there rubs the floor a lot and it hasn't come off the door yet either. I do want to add that I thought these were going to be a hard plastic, they are not they are rubber, which might seem weird at first but I assure you they work fine. 100% worth the money.
This product cut that draft and unwanted pest right out !!! Ty
Installed a few months ago~ Still working great and adhesion still sticking. Ive had ones that pealed off after one month.
