MoistureShield Meridian Composite Decking Colors
Explore Meridian’s five earthy shades, each designed with natural, variegated tones and reduced pattern repetition for a look that feels genuinely organic rather than manufactured. Whether you’re drawn to cool coastal grays or warm, sun-baked browns, Meridian’s composite decking color range makes it easy to find a match for any home style.
MoistureShield Meridian Catalina
Natural. Lasting. True.
CAPPED COMPOSITE / $$
Soft and sandy, Catalina blends muted taupe with faint gray undertones, giving it the quiet, sun-bleached look of driftwood found along a shoreline. It’s a natural fit for beach houses, transitional homes, or anywhere a calmer, less saturated color palette works better than something bold.
Thanks to the TruTexture™ finish, Catalina avoids the repetitive grain pattern common in composite decking, so the board reads more like genuine hardwood up close. That same surface technology also builds in extra resistance to scratching from furniture and foot traffic. A Solid Core sits underneath every plank, sealing out moisture, rot, and insects for the long haul, and CoolDeck® Technology keeps things noticeably cooler on bare feet during peak summer heat.

Catalina gives our deck such a soft, natural look – you’d never guess it’s not real wood, and it’s held up beautifully.
MoistureShield Meridian Citadel
Natural. Lasting. True.
CAPPED COMPOSITE / $$
Citadel leans cooler and grayer than the rest of the Meridian lineup, with a weathered, storm-swept look that suits modern coastal homes especially well. It’s the kind of neutral that lets railings, furniture, and landscaping take center stage instead of competing with the deck itself.
Low pattern repetition is baked into the TruTexture™ surface, meaning Citadel avoids the obvious repeating grain lines that give away lower-end composite boards. It also holds up better against scuffs and scratches as a result. A Solid Core runs through every board to block out moisture, rot, and insect damage permanently, and CoolDeck® Technology helps the surface stay up to 30° cooler than other composite and PVC decking on hot, sunny days.

Citadel has the perfect weathered gray look for our oceanfront deck – it holds up to the salt air beautifully.
MoistureShield Meridian Mariner
Natural. Lasting. True.
CAPPED COMPOSITE / $$
Deep and moody, Mariner pairs a reddish-brown base with darker streaking that gives it the look of aged mahogany or teak. Homeowners drawn to bold, upscale outdoor spaces often reach for Mariner when they want their deck to feel like a finished room rather than an afterthought – it pairs especially well with black hardware, string lighting, and stone fire features.
The TruTexture™ surface behind this color reduces the repetitive patterning you’d normally spot in composite decking, so the grain reads as genuinely random the way real hardwood does. That same surface adds a layer of scratch resistance for busy households. Underneath, the Solid Core locks out moisture, rot, and insects for good, and the board’s slip-resistant finish keeps footing secure – though unlike Citadel, Catalina, and Shoal, Mariner doesn’t include CoolDeck® Technology, so it’s worth keeping that in mind for sun-heavy locations.

Mariner brings such a rich, dramatic color to our patio – it looks incredible under our outdoor lighting at night.
MoistureShield Meridian Shoal
Natural. Lasting. True.
CAPPED COMPOSITE / $$
Shoal leans light and sandy, with a pale, warm undertone that brings to mind sun-bleached beach dunes. It’s an easy match for coastal cottages, Mediterranean-style homes, or any backyard where a brighter, airy palette feels more inviting than something dark or heavy.
Its TruTexture™ finish breaks up the repeating grain patterns typical of composite decking, giving Shoal a more convincing, organic wood look up close, along with added resistance to scuffing. A Solid Core runs the length of every board, keeping moisture, rot, and insects out for good, and CoolDeck® Technology keeps the surface up to 30° cooler than other composite and PVC boards – a welcome relief for bare feet on sunny afternoons.

Shoal brightened up our whole backyard – it has such a light, beachy feel and never gets too hot to walk on.
MoistureShield Meridian Shoreside
Natural. Lasting. True.
CAPPED COMPOSITE / $$
Golden and warm, Shoreside carries a honey-brown tone reminiscent of sun-warmed cedar, making it a natural fit for traditional homes, wooded lots, or backyards that call for a rich, welcoming color. It’s a shade that feels equally at home next to a swimming pool or a wooded backyard view.
The TruTexture™ surface behind Shoreside cuts down on the repetitive grain patterns common in composite decking, giving it a more convincing, one-of-a-kind wood look while also toughening the surface against scuffs. Underneath, a Solid Core protects every board from moisture, rot, and insect damage for decades, and CoolDeck® Technology keeps the surface up to 30° cooler than other composite and PVC decking – a real plus for pool decks that see direct sun most of the day.
