Product Details

The Tsunami Seal Garage Door Threshold Seal mounts to your garage floor creating the perfect seal between your door and your garage floor. The Garage Door Threshold Seal creates a tight seal for your garage door which will keep leaves, dirt, water and snow from being blown under the garage door by the wind. Also, if you have a sloped driveway or an uneven garage floor and water is seeping under your garage door, the door seal adds a 1/2 in. tall barrier to the garage floor. The door seal will also help keep out unwanted insects and snakes. By creating a better seal, your garage will stay warmer during the winter and cooler during the summer, helping to keep your energy cost down. The door seal works great with all types of garage doors including roll up doors, hinged wood doors and walk-through doors. The one-piece strip is permanently secured to the garage floor with the included Premium Polyurethane Construction Adhesive, specifically designed to bond with PVC. Each kit includes the one-piece Threshold Seal, Premium Polyurethane Construction Adhesive, a metal caulking gun and color installation instructions. Comes with a lifetime warranty.

    Q:How tall is it at it’s highest

    Answer This Question

    A:  I believe it is 1/2 inch high. Try to do your install on a hot day and lay this out in the sun first to allow it to relax. It comes rolled up in the box. Cut it longer than you think you need and then final fit it and then trim it. Good luck and God Bless

        Q:why the switch to loctite?
        by|May 7, 2023

        Answer This Question

        A:  Due to supply chain issues it was necessary to find another high quality polyurethane construction adhesive that is designed to adhere to plastics. This enables us to continue to offer our lifetime warranty, as it is more likely to endure over time than other types of adhesives.

          A:  Not sure what came with mine, but I did exactly what the instructions said. I really cleaned the area and probably used too much alcohol , let it dry really well. It has stuck perfectly for like 3 years so far. Workame with it was totalls perfectly. Nice product. As I remember the caulking gun that came with it didn't work at all but no big deal.

              Great kit, horrible caulking gun
              We installed this kit this afternoon and everything was going just fine until we went to use the caulking gun that came with it. The gun didn't even last 1/4 of the way thru the job. Thank goodness we had our own and were able to finish applying the adhesive. Liquid Nails is a very thick, strong adhesive and I think they include the cheapest caulking gun ever made. No idea how the threshold kit is going to work, we just installed it. But wanted to warn people to have their own caulking gun ready to use.

                The kit arrived with all of the components in it. 1 Floor Threshold, 1 Caulking Gun, and 2 Tubes ...
                The kit arrived with all of the components in it. 1 Floor Threshold, 1 Caulking Gun, and 2 Tubes of Liquid Nails. 1 Tube of Liquid Nails was punctured side ways - not a good thing - I searched for replacement tubes but none of this type is available hardly anywhere! I had to contact the manufacturer and they recommended LN2000 Fuze It. Unfortunately it comes in a 9oz container - so I did not get all the stuff I needed. I had to buy an extra tube (Glad I did - I needed it - about half a tube) - there is no directions on how far down to cut the tube for a bead (they should supply you with a precut dispensing tube - so your bead is the same thickness as theirs). I was probably a bit thicker than the kit manufacturer - so contrary to the company saying you have everything you need in the kit - YOU DON'T - also no rubbing alcohol to clean the garage surface. Also they use this special LN950 Polyurethane - so if there is an issue (like in my case a punctured tube from shipment and the fact I needed more than what the two tubes have) you can't get it or you need to play shipping tag first pkg right wins. I wish the threshold was 4 to 5 inches longer as it does not stretch to the Door Track ! I used my own caulk gun as theirs felt a little flimsy (just like other reviewers have noted) and like it could not handle these tubes - the force required to squeeze out material was pretty hefty so using my gun worked fine. I have not seen it hold up against rain yet so the jury is still out. 1. Tube damaged in shipping. 2. LN950 - not available to replace bad tubes or to get extra (they should supply 24-25oz oz of material.) 3. No Rubbing alcohol to clean the floor with. (They said I have everything I need in the kit and I did not..) 4. No precut dispensing tube for the caulk material - the tubes screw on the canisters so this should be provided. 5. Track should actually be 4 inches longer than the door opening to reach the guide tracks of the door. So those are the reasons I am rating this a 3 . If they want a 5 they need to fix these issues.

                Easier than I expected
                I'd been looking at getting a threshold kit for my garage door for years. Over the years the concrete slab for the driveway and the garage floor have moved, creating a gap between the bottom the garage door and the concrete on one side. However, I was concerned that it would be difficult to install, and not work with my painted floor. The latter is no longer a problem as the floor is well seasoned, but the former was still a concern. I didn't need to worry. Just roll out the threshold, let it uncurl and lay flat (easier in warm weather), cut it to size with a sharp utility knife (use a straightedge to get the best cut), close the door and push the threshold into place, and mark the inner edge of the strip. Do the same on the outer-facing side, and you're ready to lay down the adhesive. Three lines are all it takes, and then place the threshold over the adhesive while making sure it stays between the lines you drew. Keep a putty knife handy for any adhesive that oozes out; you can scrape it up easily before it dries. Then lower the door and wait 24 hours for it to take a permanent set. That's it! Easy. Plus it has really reduced the amount of dust and dirt driven under the door and into my garage.

                Overall good product but ,supplied, installation tool of poor quality.
                The product, Black door threshold kit, certainly was sufficient for the application but the Caulking Gun, which was supplied as the installation equipment, was inferior. The caulking gun construction was of light gage sheet metal and promptly collapsed after a few squeezes. Fortunately I had a commercial Caulking Gun in my truck to finish the project. For the cost of the kit the installation equipment should be a bit beefier. I would recommend the threshold but should replace the flimsy caulk gun with a more sturdy gun. We have had occasion to test the threshold with rain and it holds very well.

                Excellent quality product. Did have to use a different adhesive. Supplied adhesive was very hard to get out even with a heavy duty gun.
