Advanced Pvc 5/4x6x12 Slate Gray Square Edge Deck Board

Product Overview
Finish your outdoor living project with crisp, professional lines and a bold structural border using the TimberTech Advanced PVC 5/4x6x12 Slate Gray Square Edge Deck Board. Sourced from TimberTech's high-performance polymer lines, Slate Gray delivers a sophisticated, uniform dark gray aesthetic that grounds modern architectural home designs. Because these versatile 12-foot boards feature a solid square edge profile, they are the industry standard for installing perimeter picture-frame borders, breaker boards down long runs, cocktail top railings, and outdoor stair step treads where grooved slots must not be exposed to plain view.

Advanced Capped Polymer Engineering
Unlike traditional composite decking that mixes wood flour with plastic, TimberTech Advanced PVC boards are engineered from 100% cellular polymer materials. This synthetic core is completely wrapped in a robust, multi-sided protective cap that completely blocks out moisture. It provides industry-leading resistance against UV color fading, severe scratching, permanent stains, mold growth, and insect damage, keeping your deck looking flawless for decades without ever requiring sanding, staining, or painting.

Frequently Asked Questions

• What is the benefit of a 12-foot square edge board over longer options? While 16-ft and 20-ft boards are excellent for long, unbroken field runs, 12-foot square edge boards are ideal for smaller landing platforms, building stair treads, or running short breaker boards and picture-frame accents without generating excessive scrap material waste.
• Does TimberTech Advanced PVC get overly hot in direct sunlight? While darker colors like Slate Gray absorb more solar heat than light tan colors, TimberTech Advanced PVC deck boards are engineered to stay up to 30% cooler to the touch than traditional competitive wood-plastic composite decking, making them much more comfortable for bare feet and pets.
• How do you clean and maintain a TimberTech PVC deck surface? No seasonal sealing or staining is ever required. For general maintenance, simply sweep away loose dirt and wash the deck surface using a stiff bristle brush, warm water, and a mild household soap or a dedicated composite cleaner like TimberTech DeckCleaner.
