## Questions & Answers

**Q: can I double one on top of the other to cover a larger gap? If not, please rec a product that covers a 2" gap. Thanks!**
A: No, that won’t work, I tried! Order this instead. It’s more expensive but super thick and sticky, comes with brads as well and closed over a 2” gap on my screen door. Yahhh …no more critters can get in! I’m ordering another set today to do both sides of the storm door.

**Q: Can it come off easily without ruining door?**
A: Yes, mine did. You may need to apply a blow dryer to heat it up some. But it comes off.

**Q: Will this damage a painted door or wood door upon removal?**
A: Yes, it destroye the paint on my bedroom door don't do it!

**Q: Does this work better when placed inside or outside the door?**
A: If it is an interior door like a bedroom door, you can put it on either side.  If it is a main door leading to the outside, I recommend using it on the inside.  You can put it on the outside but weather conditions will deteriorate the quality of the product over time.

### ⭐⭐⭐⭐ Works great
*by K***T on December 28, 2025*

We had a really bad draft coming from our front door and this has helped a lot! Was easy to put on the door and has held up well. Only downside is I haven’t found a thin enough door mat that doesn’t get shoved over every time I open the door.
