M-D Building Products 50101 20 ft. Gray Vinyl Garage Door Threshold Kit

I ordered a 20 foot strip to have extra. I cut it to the correct length of 16 foot 8 1/2 inches. I rolled it out to season and lay flat. In the mean time, I took the strip and using each end, I custom cut each end to fit the left side and the right side. Now that I had this pattern. I laid this pattern on each side of the full length piece. I put it in place on both sides - making a back line on the epoxied floor with a market. I snapped a line with a chalk line than with a 4 foot straight edge, drew a line with the market. I also made a center line. The center line allowed me to stay on track with the caulking gun. I pit a line of caulk an inch on either side of the center line than a bead down the center. I only did half of the floor. I laid it down keeping the back of the product on the rear line I drew. When I reached a little before the middle, I laid the product but with a hump to keep it from falling in the caulking. I did the other half of the floor. perfect and easy. Just walk down the threshold, back n forth a few times, keeping it on your line. Once you think you have all the caulking spread, close the door on it and check your line. If it's on line - goodnight.
