G-Tape - Acrylic Flashing 4" x 65' Nichigo G-Tape GT3040BK04

Works great, very sticky, not a bad price for how much you get. Just as good as zip tape

This tape is the best, it’s pricy but worth it. Sticks really well to anything and if it sticks to itself you can pull it apart. I used it for support posts at the ground level and it looks great goes on easy if it lasts half as long as they say it’s the bomb.

Purchased this to help seal my back door. It gets hit with all the weather. Very sturdy it’s help up against the sun and the rain!

Good product for sure and even though i don't have a long term test, better safe than sorry. it adheres like crazy to the wood after a couple of days. No doubt it will add some life to your deck for sure from water in the wood checking, and additional splitting from screws. Even better use this and plug your deck, not use all the other fancy stuff if you want more prevent of water to the top of the joists checks

Why did you pick this product vs others?: Talking with local contractors, this is their preferred joist tape. The quality and durability of treated lumber is so bad these days that this additional moisture barrier now seems essential on horizontal surfaces. It is an expensive add on to any large project. At typical summer temperatures the tape is INCREDIBLY sticky so make a good plan on how to attach it and peel off backing tape. In my experience, the product works best above 60F and the wood surfaces need to be clean and very dry. The question remains will this tape, properly applied, actually protect surfaces and extend the life of treated lumber? Only years will tell.

Easy to use, doesn’t react to oil based stains, can be torn like duct tape.

great

Used this on a deck 6 yrs ago and recently checked and its still giving great protection to framing beneath
