Why should you use Nichigo G-Tape on decks?
Water finds a way.
In the construction industry, it is always important to keep that in mind. Water ALWAYS finds a way. This is especially true when it comes to deck building.
All things being equal, wood rot is one of the first places a deck begins to fail. Being exposed to the elements 365 days a year means there are many opportunities for water to find its way into a board and accelerate the degradation.
There are two weak spots in deck lumber: horizontal surfaces and fastener punctures. With the growing composite deck board market, those boards act like a seal trapping water between the composite boards and the wooden joist boards underneath. Punctures drive through treatments exposing the fresh, raw wood underneath.
The weakness is then multiplied on horizontal surfaces WITH fastener punctures. We designed 3040BK to protect decks from this very issue.
To demonstrate just how much protection 3040BK offers, we turned to our R/D lab to run accelerated tests. We drove nails through our 3040BK, sealed off the top, poured dyed water in, and placed collection cups underneath to see what would soak through.
Next, our team ran two tests, high temp and high UV exposure. Both tests ran for the equivalent of 20 years outdoor exposure.
Turns out our collection cups weren’t necessary, as neither test had any failures. All 10 nails in each test were perfectly dry and 3040BK was still holding strong.
Use 3040BK to make water find a different way.
