These was easy to install an works great keeping water out of my shed

It's a little fiddly to fit, but works perfectly when installed, creating a nice seal to my double garage door.
Make sure you thoroughly clean the area where you're installing, lay it out flat, cut to size and glue down.
I left it out in ghe hot sun to soften up and remove the kinks, and used a large tube of gorilla glue for caulk guns.

We just had the first tropical thunderstorm for Southern california and when I heard the weather forecast for it I rushed to buy one of these. The reason being, that our garage constantly gets water leaking underneath the garage door, halfway into the space every time it rains. The previous owner didn't take good care of the garage door trimming or concrete floor seal so I decided to DIY this one myself. I ripped out their old and useless previous stuff. First I purchased the top garage door rubber hose/base trim from Lowes. (Your basic T edge rubber tubing for the metal rail tracking of the door base). I found some tips that if you purchase WD 40 silicon spray lubricant, that it makes it easier for a solo person to easily pull the new rubber across the tracking rail themselves. So I did and it worked great! after the separate top rubber seal install, I then installed this guy for the concrete floor. The tips in the reviews were more than helpful to make sure I was able to (a) do it myself and (b) do it right the first time. Thank you fellow reviewers for your tips!
So I first power washed my concrete floor edge so it was free of all gunk and dirt. This of course helps the adhesive I was about to place, actually stick well. Then I cut a piece of this threshold seal strip off that I wasn't going to need and used that shorter piece to measure and mark off sections at a time on my floor, where the trim would soon be laying down. This took a long time but worth it. I used a sharpie to draw lines around the edges of where the rubber seal was going to be placed. Constantly lowering my garage door to test and see if the newly added top tube seal would sit flush with this guy. Then after making my markings, I went ahead and grabbed the full strip this time, aligned it to my sharpie markings and to test before glueing. I again - closed the garage door one more time to make sure my top rubber tracking seal sat flush with this bottom seal strip appropriately and into the curve. I made a few minor adjustments to the rubber placements in certain sections by marking new sharpie lines here or there and then I was finally ready for the permanent glue down. I used the LOCTITE PL 3 X PREMIUM as some reviewers noted. I first put this loctite caulking close to (not on) the edges and then did zig zags in-between those edges. Then I slowly pressed the rubber seal sections one chunk at a time (remember I was doing this all by myself), with the remaining seal waiting to be set next thrown over my shoulder as I pressed sections at a time onto the caulking and making sure I was following my sharpie lines. Luckily you have time with the glue to make adjustments and slide around the rubber slightly before committing to the positioning. After the whole rubber seal was fully laying on the glue and aligned, I slowly walked on it, making sure it didn't accidentally slide around the floor underneath my shoes and making sure it didn't accidentally misalign. After walking on it and readjusting here or there - I put some heavy rocks and bricks on sections of it to keep it weighted as it dried. While I waited for the glue to do its thing, I had some extra Sika Flex caulking left over from my other house projects and put a bit at the edges/end of my garage seal/wood trim where water could get in to prevent water from rolling back in. after about an hour I closed my garage door so the weight of the door could continue the setting process from there. Relieved to report the large rain pour that weekend never got in, the inside floor stayed dry and this worked like a charm! Thank you again reviewers for your excellent tips and tricks.

This is probably the best thing I have bought for my garage. Before installing this We have had a little bit of water that seeps in underneath the garage door when it rains.
I put this down as a test fit with a temporary glue to make sure that the garage door will close fully and not have any issues. Once I was sure that there would be no issues with the garage door closing. I used construction adhesive to adhere it to the garage floor. It has not moved since. It has kept out a lot of the water that would seep under the door.
Any of the water that does still seep in only happens during heavy rains, and it's a very minimal amount near the corners of the garage door.

Fixed my leaky garage door issue . Was a bit of a pain to install . Do it on a warm day . Roll the thing out flat in the sun and let it get soft . Take your time and measure , cut and glue down .
