A: I would not.. the material is thin and designed to seal up nails and such when shingles are applied.. I would use a thicker material like a flat roof membrane
A: Yes, this is a high quality product and you should be fine using the remainder as joist tape.
A: Kevin, Because the structural integrity of your deck will depend in no small part on the health of the ledger over time I used this product OVER the ledger. Not only that, I used pressure treated ground contact Doug Fir for the ledger. I attached it to the house with galvanized 5/8" bolts and/or threaded rods with the same 1-1/2" Doug Fir plates spanning perpendicular across the wall studs on the INSIDE of the house and then installed the washers and nuts. Back on the outside, I then started the Grace flashing about 4" above the ledger coming down the wall, over and down the face of the ledger, back to the wall, then down the wall another 4". After all the joists were installed I installed aluminum flashing on the wall above the deck which overlapped that 4" Grace Flashing. My idea was to never have the ledger see a single drop of water. It's been three years and it to date it hasn't. I seriously doubt it ever will. As for using the remainder for joint tape, I don't know what joints you're refering to, but if the purpose is to keep water from entering the ends of lumber, it's a good idea. I also used Copper Green Wood preservative on every joint and in ever bolt hole I drilled. I also placed self-adhesive aluminum tape across the the top edge of every joist. I wanted this to be a once in two life times installation. So far it looks like it will last at least that long. ;-) Good Luck.
A: May 16, 2020 Hi Gary, I am not familiar with this product, but I took the time to visit the link you included above. You have probably read Ken's experience which I have copied below. It sounds to me that if you are adding this product on top of the Grace detail membrane for aesthetic reasons - (i.e., because it's white and visible and hides the black of the Grace membrane) - and it's "trapped" by being subsequently covered by the rim board you'd be OK. That said, it sounds brittle and apparently does not hold a formed (bent) shape well on its own. As far as water protection alone is concerned, the Grace membrane would be sufficient. If water protection is your only concern I wouldn't bother adding it. The Grace membrane is sufficient for that purpose. I used it three years ago and I am noticing not one bit of degradation. The Grace membrane has a thick rubbery self-adhesive backing which closes around screws (or nail, but I don't use nails). This product clearly does not, so it's going to have tiny little leakage points everywhere it's penetrated by a screw or nail. If it's a second layer for the aesthetics of being white, sure use it. If you're thinking of adding it as a second layer primarily for additional water protection only I wouldn't bother with the expense (or hassle of installation). I hope this helps. February 4, 2020 My experience with using this product was very negative. I only needed a small amount, several feet worth, and the smallest size available was 30 feet, far more than needed (and extra costly). In needing to make sharp bends with it, I was unable to do so and found it "floppy" and when adhered to its intended location, I found it "wavy" and unattractive for its purpose. I ended up ripping it down, and am stuck with about 26' of it. I learned the hard way, and had I seen such a review as this, I'd have spared myself the time and frustration. I ended up using 3/8" PVC board as a far better alternative. Ken
