Waterproof Deck Coatings Protect and Serve
Just as the police work quietly in the background to keep you safe, waterproof coatings do the same for your deck.
Water decreases the useful life of all decks; it doesn’t matter what construction materials are used.
How Waterproof Deck Coatings Protect Wood Decks
Wood is naturally porous, meaning it absorbs moisture like a sponge. A waterproof deck coating protects wood by sealing the surface and penetrating the wood fibers. Once cured, the coating forms a flexible membrane that blocks rain and humidity from entering the wood.
This prevents common problems such as swelling, warping, rot, and mold growth. Because high-quality coatings remain elastic, they move with the wood as temperatures change, preventing cracks that would allow water back in. In short, the coating keeps the wood dry, stable, and structurally sound.
How Waterproof Deck Coatings Protect Concrete Decks
Concrete may look solid, but it is highly porous. Water easily travels through microscopic pores and cracks. A waterproof deck coating protects concrete by filling those pores and bonding to the surface, creating a continuous moisture barrier.
This stops water from penetrating into the slab, preventing cracking, spalling, and freeze-thaw damage. The coating also seals small surface cracks and joints where water usually enters. By keeping moisture out, the concrete stays stronger and lasts significantly longer.
The finished waterproof deck coating for this coastal deck gives the surface a smooth, fresh, vibrant finish.
Protecting from More Than Water
Deck coatings in Orange County fight back against more than just rain. They also protect from:
- Extreme sun
- Daily moisture cycles
- Temperature swings
- Occasional heavy storms
- Coastal salt air
Waterproof deck coatings are sunglasses for your deck
UV Protection
Orange County gets year-round sunshine, and UV radiation causes more destruction than rain. Without a protective coating, wood dries out, cracks, and splinters; concrete becomes brittle and chalky; and surface materials break down faster
A deck coating acts like sunscreen for your deck, blocking UV rays and slowing surface damage.
Coastal Moisture and Inland Dew
Even when it doesn’t rain, Orange County decks get wet. Moisture exposure happens when morning dew settles on decks, coastal fog moves inland carrying moisture, and humidity builds overnight creating dew on surfaces. Over time, this repeated damp-dry cycle causes rot, cracking, and structural weakening.
Occasional Heavy Storms
Southern California may be dry most of the year, but when it rains, it pours. Over the Christmas holidays in 2025, Orange County experienced heavy rains, flash flooding and mudslides. Even if your home held up to the deluge, how did your deck fare?
Without waterproofing:
- Water pools on decks
- Moisture penetrates quickly
- Damage accelerates during storms
When you protect with a waterproof deck coating, you protect your decks before those intense storms hit.
Salt Air and Humidity in Coastal Areas
Waterproof deck coatings protect coastal decks from moisture in the air as well as moisture that falls from the sky. In addition to humidity, coastal air contains salt.
If your deck is near the coast:
- Salt accelerates corrosion
- Metal fasteners rust faster
- Surface materials degrade
Deck coatings form a protective shield against salt exposure and protect the deck and the deck structure.
Waterproof Deck Coatings Applied Right
A waterproof deck coating applied improperly is worse than no protection at all. That’s because a bad coating offers false security. You think you have protection right up until the point you discover you have no protection at all.
