Deck flashing tape
Easy to work with and will work well in our deck refinishing project. My daughter who is not a handyperson reports that she was able to apply with ease. Lots more to do but product performs as described and Midland got them to us very timely. Thanks.

Good Product
I order this flashing for my 32 x 20 deck refinishing project. The tape adhere fairly well, sometime not quite sticking on the edge of the beam but overall working well. Nice choice for a renovation as the old nail holes would be a serious conduit for water and potentially rot. Also makes a nice black backdrop for my TREX decking where you would otherwise be looking at green or old lumber through the 1/4" spacing of the boards. Midland was great and shipped promptly.

Great product, easy to use
In replacing my 22 year-old wood deck, which was rotting out, I am using this flashing between my composite decking and wood joists to avoid the rot which started around all of the old screws. The flashing is high quality and molds easily around my 2X10 joists. It creates a durable barrier and I am very pleased with it. In fact, I just ordered more. I would highly recommend it.

164258 Deck Flash Barrier 3 x 75 ft.
Great experience with this product on my deck joists and other flat areas. The flashing material was very durable, the paper backing came off easily and easy to apply to the deck joists. Clearly seals the nail holes in the joists and seals the new screws when setting the deck boards. I could see other uses for this products in areas to control and prevent moisture. The price was competitive and the delivery was spot on. I would recommend to others for sealing up deck joists.

164258-Deck Flash Barrier 3 x 75 ft
I received my order quickly, thanks for the speedy shipping. My deck crew and I applied 10 rolls of 3" X 75' Deck Flash Barrier on my new deck. The intital rolls (the first we applied) were difficult to get out of the packaging (maybe the were older, I don't know) anyway the other half un-packaged easier. Once we got the hang of applying it we got it on in about 2 hours. We could have done it about 25% quicker if the first rolls came out of their packages better. The minor problem was the clear plastic on the sides of the rolls. Even heating the older rolls it was still difficult it pill off. The product adhesive held it tight on the new joist for several days during heavy rain plus wind, the deck was later installed over the Deck Flashing and the black color makes the joints look better. My contractor who has been decking for 35 years had never heard of the product but now intends to use it on his high end customers. I can only hope it works, but the only way to determine its value is over time. My son & I torn the existing 32 year old down, the joist were rotten mostly around the nail holes in the top of the joist, thus the reason I found the product on the internet. The material seems well suited for the job, the adhesive is good! We tested the tear factor, laterial strenght and its ability to seal the screw hole when they were applied. Compared to joist that didn't have Deck Flashing on them the covered ones appeared much drier after the rain. So far I'm satisfied with the product and service, I think the minor investment will pay off now and in the future. James

I should have purchased 4 inch. This product will not adhere to the sides of the joists. Within an hour after application the barrier was coming loose from the sides. The temperature was in the mid sixties and the deck is in full sun. Hopefully it will still be effective but I couldn't recommend this product.
