I bought these door strip to stick at the bottom of our front door. They have adhesive tape which made it easy to install, but the adhesive has rapidly worn off and the strip has come loose. So here we go hands on D.I.Y....
Here is a shot of the loose door strip. Firstly, carefully remove the strip from the door
Then, clean the back of the strip with a chemical like Thinners
Also clean the surface area on the door where you will be sticking the strip to
Now use some Bison Universal Contact Glue and put a film of glue on the door. Any kind of universal glue would do but Bison is at the top of my list!
Make sure that you put a film of glue on the contact area of the strip. Allow the glue on both surfaces to dry for up to 45 Minutes
Lastly carefully align and then evenly push the strip onto the bottom of the door
That's it in a nutshell!
