Expert Verdict — Reviewed by the SuperArbor Pro Desk
Synthetic underlayment like Gator-Skin replaces heavy #30 felt and offers better tear resistance and walkability on the deck. Because it is 42 in. wide, lap and fasten per the manufacturer's instructions and adjust coverage math for overlaps. Its Miami-Dade and FBC approvals make it a strong choice for high-wind coastal jobs.
Synthetic underlayment can be slippery, especially when wet or dusty, so wear non-slip footwear and use fall protection while installing.
Order APOC Gator-Skin 9 mil synthetic underlayment today and cover 10 squares per roll with code-approved protection.
