Universal Garage Door Threshold Seal Strip, Bottom Weather Stripping Replacement Rubber Waterproof 20 FT Length（Green）

I needed something at each end of my garage door due to sinking concrete. This worked great and no more water in my garage . The company that installed my garage door recommended them.

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.

So, first of all the dislikes1. No instructions2. Should include adhesive ( does not)3. Ends curl so you out of some of the material. Out of 20ft I had to cut about 10% of the product( I always plan for 10-20% waste)The likes:1. Cuts easy2. Seems lay flat once installedI do not know if it will keep the rain out, until I get another heavy down pour

Good project

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.
