Storm Shield® 16 ft Garage Door Seal Threshold Strip - Durable PVC Rubber Seal Strip - Flame Resistant, Weatherproofing Garage Door Installation - Epoxy Adhesive - Made in The USA

I exaggerate only slightly. I recently converted my carport to a garage with an overhead door. There were a couple of issues with this. First, the carport slab had no little step down at the overhead door line, as most slabs poured for a garage would have. Second, the slab had a slope built into it from side to side, so it was 1 1/2" higher on the left side of the door than on the right.I talked to the manufacturer of the door about the slope issue. They said that the door had to be installed level, not parallel to the slab. To fill the gap on the right side of the door, they advised me to stuff the right end of the U shaped gasket on the bottom of the door something like a slice of a pool noodle to compensate for the slope. I did my best to a cut a tapered wedge out of the noodle about 6 feet long and pushed it into the gasket. It did look pretty good. I could see just a sliver of light under the far right end of the door, but other than that, it seemed to fill the gap.The next day, we had 2" of rain and water flowed under the door along almost the entire length and there was a torrent on the right side, between the door and wall. I looked outside to see what was going on and saw that the rain pouring off the roof and falling in front of the door was ponding almost an inch deep along the whole length of the door. Part of the trouble was the slab itself. Because it was not exactly as smooth as glass, the seal really couldn't do its job. I live in South Florida and torrential rainfall is a common occurrence in the summer months. I had visions of my newly created garage workshop flooding several times a week.In a panic, I did a search and found the Storm Shield Garage Door Threshold. It looked like it might help, so I ordered it immediately. My door is 12' - 2" wide and the 16' threshold I ordered measured just over 17'. I cut it to length and installed it according to the instructions. The 2 tubes of liquid nails that came with it were just enough to make the beads described in the instructions. If you have a 16' door, I recommend that you pick up an extra tube of liquid nails, just to be sure you don't run out. In addition to the liquid nails, I ran a bead of silicone caulk along the edge of the threshold to seal it. I also cut up some pieces of leftover threshold and made a dam at each end of the threshold, blocking the space between the threshold and the wall, and caulking the spaces as needed.Since I installed it, there have been a number of downpours, but not a drop has entered the garage. I am so happy!

I installed this in our garage to help keep the rain water and snow from coming into the garage. Our garage has a tree next to it that is cracking the foundation and makes the garage door seal not connect in some places. The lip that this storm shield provides helps keep the rain from flowing into the garage.The kit came with instructions and 2 small tubes of cement epoxy. Ditch the tubes of glue that comes with this thing, or use them on something else. Get a caulk gun and 2 or 3 tubes of liquid nails that is formulated to bond to concrete and is waterproof. Use a chalk line to snap a line then apply your glue in even lines, 4 lines sealing the ends, then gently lay the shield on the glue and press down and smooth out. Takes about a 1/2 hour to install, 1 person can do it, an extra hand is very useful. Add some weight on the seal for a couple hours. Make sure to apply the shield when it is dry and not going to rain.The 16 foot fit perfectly in my garage, with enough to carefully cut around the garage door rails. So far with 6 months and a winter in NE Ohio this has done the job. It seals perfectly with the bottom of the garage, has kept the garage dry. last winter the garage seal stuck to the frozen ground and pulled the door off the tracks and ripped the seal. However this winter we noticed that the rubber seal prevented any water from freezing to the garage door.I'd recommend this to anyone who need to add a bit of a barrier to the elements in the garage. -1 star for the crappy and lack of enough glue to finish the job. 3 tubes of liquid nails adds about another $15 to the total cost to purchase and install but i would suggest not using the supplied glue. The 2 tubes are hard to squeeze out and there just isn't enough to do the job.

After reading all of the reviews on this and similar products, I went with the Storm Shield (16ft), based on price. Knowing that everyone else said the glue included with the kit was crappy, I tossed it and and got two tubes of heavy duty liquid nails. It worked very well and was enough to do a 16ft run with about a 1/4 tube to spare. I just used more on the ends, since several reviewers mentioned that the ends "curl up". I installed this product in mid-October and the weather was fairly cool (low-60's), meaning the thick rubber of the Storm Shield was not easy to work with and indeed, since the product arrives rolled up in a box, even unrolling it flat overnight, with weight on each end, did not stop the ends from curling up again. I ended up using a heat gun (think serious industrial blow dryer), and worked back and forth on both sides of the curled up rubber, about 8 inches away. After about 5-7 minutes on each side, it made the rubber pliable enough to work out the curls, so it was totally flat when I moved it into position on the ground! The heat gun did not burn, bubble or melt the rubber - but I was careful, checking it often. Took the advice of other reviewers and bought a small bottle of etching liquid for the concrete, so that the glue would adhere to the concrete properly and this was a good call. Finally, I used a high quality exterior caulk and did both sides of the Storm Shield, to help ensure no water could get underneath. Also a good call.This product has kept 90% of the water out and in my case it was really just in one corner of the garage that was the problem. I'm happy with the purchase and would say if you add the heat gun (beg, borrow or steal), you should be good to go.
