At Eled Decking, we specialize in protecting decks from the elements so they stay strong, safe, and beautiful year-round. Here’s everything you need to know about keeping your deck water-resistant and weather-ready.

Why Waterproofing is Essential for Long Island Decks
Moisture is your deck’s biggest enemy. Over time, exposure to rain, snow, and humidity can:
-
Weaken wood fibers and cause splintering
-
Encourage mold and mildew growth that makes surfaces slippery
-
Rust metal fasteners, compromising stability
-
Shorten your deck’s lifespan significantly
A well-maintained waterproof barrier prevents water infiltration, keeping your deck stronger for longer.
Best Waterproofing Options for Your Deck
1. Sealants
Clear or tinted sealants penetrate wood fibers, creating a protective layer that repels water.
Pros: Affordable, easy to apply, preserves natural wood grain.
Cons: Needs reapplication every 1–2 years.
2. Stains with Waterproofing Properties
These add color and UV protection while sealing against moisture.
Pros: Two-in-one finish, improves aesthetics.
Cons: Requires periodic reapplication.
3. Waterproof Membrane Systems
Installed beneath the decking boards, these membranes direct water away from the frame.
Pros: Protects structure, allows for dry storage under elevated decks.
Cons: Higher installation cost.
4. Composite Decking Materials
Made from a blend of wood fibers and plastic, composite boards are naturally moisture-resistant.
Pros: Low maintenance, long lifespan, no need for sealing.
Cons: Higher initial investment.
Seasonal Waterproofing Maintenance Tips
-
Clean Your Deck Before Sealing – Remove debris, dirt, and mildew with a gentle deck cleaner.
-
Inspect for Damage – Replace rotted or cracked boards before waterproofing.
-
Apply Products in Dry Conditions – Ensure at least 48 hours of dry weather for proper curing.
-
Reapply as Needed – Check your deck annually to see if water still beads up on the surface.
