52050 Lifetime Garage Door Threshold Seal Kit - 52 Inch, Brown Weather Stripping for Home & Garage Protection Against Drafts, Water, Pests & Noise

The Tsunami Seal works amazingly well. Despite having a roll-up garage door with very good bottom seal, a heavy rain and wind event (common here in Astoria, OR) always resulted in water intrusion -- that is until we installed the Tsunami Seal threshold. Absolutely no water intrusion now.Installation was straightforward and took less than an hour. I do, however, have what I hope are a few helpful hints:1) I have a 16' garage door opening (2-car garage), but purchased the 18' threshold. This was a good decision as simple cut-outs for the garage door tracks allowed for a nice extra foot on both ends of the threshold. This extra length provided a more stable and protective installation of the threshold.2) BEFORE starting, go out a buy a "real" caulking gun. It is nice that one is included with the product, but it was awfully cheap and became totally useless in the middle of laying down the adhesive due to the handle of the gun bending (making it impossible to push out the adhesive).3) BEFORE starting, make sure that the Liquid Nails adhesive is not too cold. Keep it inside or warm it up a bit before beginning because if the tubes are cool, it is a real bear to lay down rows of the adhesive without a great deal of extra effort (don't forget, you are laying down three lines of adhesive (over 50 feet for a typical two car garage).4) BEFORE starting, reverse-roll the threshold (and keep it so rolled for some time). The heavy-duty construction of the seal and the fact that it comes rolled up fairly tight makes it difficult (especially at the ends) to get it to lay flat, and you need to have it lay flat for installation. Follow the instructions and leave the garage door completely closed for at least 24 hours -- I kept weighted boards on both ends of the threshold to keep it from curling up.5) Some adhesive may squeeze out when the threshold is first laid down, and during the 24 hours with the weight of the garage door on it, some additional adhesive may squeeze out. To prevent any excess adhesive adhering to the bottom of the garage door (or garage door seal), I placed aluminum foil along the length of the outside edge of the threshold. Indeed some adhesive did get squeezed out, but the aluminum foil prevented it from sticking to the garage door bottom seal.That's about it. Again, a great product and corrected what had been a longtime, ongoing problem.
