Jin&BaoUniversal Garage Door Threshold Seal Strip, Bottom Weather Stripping Replacement Rubber Waterproof 20 FT Length

Survived the first rain and faired extremely well. This was super easy to put down on our smooth garage surface. I bought two rolls and it worked great for our 18" garage door and our two 10" ones. It's very thick and heavy plastic so I feel like this will last. I unrolled it a day or two before I installed it to let it sit and unwind but didn't seem necessary. I've only just installed it but I used Gorilla heavy duty glue and it seems to have done it well. I also used black DAP Dynaflex Ultra on the edges, then went back over the outside edge and make a seal on that as well. I used white caulk on the inside to connect the inside to the edge of the product as well.I recommend cleaning the area well, putting it down, closing the garage on top of it, then lining it up straight with the garage door. Then trace it with a pencil on both sides of where it sits. After that put the glue down and if you follow the same pattern I did, put the caulk on the edges so nothing slips under.

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.

I have two garage doors so I bought the 20ft role which was more than enough to use for both entrance ways.The strip comes rolled up so I had to lay it out in the sun for a while to flatten out. Even then, the most interior part of where it was rolled never fully flattened, but since I only needed about 17ft I just didn’t use that end.It’s very easy to cut as I simply used a strong pair of scissors. The longest part of the process was measuring and sizing to make sure I had it in the right place before applying the adhesive. Once I had everything lined up I took a sharpie marker and made two lines, one on the top and one on the bottom of the strip. I found this helpful for when applying the adhesive and not wanting to then think about placement. By pre-marking it the guess work was taken out of it and I could just lay the strip inside the lines.The hardest part is laying the strip down by yourself. Simply because it’s a floppy piece of rubber and goes much easier if you have someone hold one end as you lay the strip down, but it’s doable by yourself, just easier with help. I did one door myself and one with a helper so tested it both ways.I read a lot of people had problems with adhesion but I used Gorilla Ultimate Heavy Duty Construction Adhesive and it worked great.Since I’ve installed these we’ve had some pretty severe storms and overall it’s helped keep the water out. I wouldn’t say it’s bone dry but it’s definitely been a huge improvement from what I was getting previously. For the cost and minimal effort to install I’d definitely recommend.

Easy to install and stays in place even without glue seals garage door so not leak

material is flexible, pleasing to look at easy to install, you must purchase the recommended glue, and does a great job at keeping the water out of your garage

It works great! I have always had some water getting under my garage door and this stopped it. Lay it out in the sun to warm it up and make it softer. Measure your required length (measure twice/three times cut once)😀. Place it down on the floor, lower the garage door to hold it in place, adjust the position as needed, use a pencil to mark the borders on each side of the seal. For a really clean look put masking tape along the border of the seal, you’ll need 2 tubes of adhesive for a standard 2 car garage door, put down the adhesive then spread it out and then put the seal down. Then press it down to seal. Use something to roll over the seal to get it to seal tight to the floor. Bike tire, wheel barrow, something like that and then close the garage door down on it. Adjust the position if needed.

Fit perfect seals perfect great quality easy to install

I installed across my garage door and it worked perfectly, then the hot sun got to it and it shrank. about 1/2 inch on one end and about 3 inches on the other. Now i have to calk to keep the rain out. If it wasn't for that it would have been 5 stars.
