Grande Petronas Oak Light Brown Waterproof WPC | COREtec Floors

What is Grande Petronas Oak?

Grande Petronas Oak is a waterproof, wood-look WPC floor in a warm honey-gold brown shade, with a heavy-duty, high-traffic wear layer for a low-maintenance, practical finish.

Is it waterproof?

Yes — 100% waterproof. Stable against concrete-slab humidity and seasonal moisture variation, so Grande Petronas Oak suits below-grade rooms once the slab passes a moisture test; clean up standing water promptly. Not approved for outdoor installation.

How durable is it, and what traffic can it take?

The surface of Grande Petronas Oak is finished with a 30 mil wear layer — that's approximately 0.76 mm — made for heavy residential use and many commercial applications, giving you exceptional protection against scratches, scuffs, and everyday wear. A notably thick, hard-wearing surface for its class.

Will it hold up to daily life?

At 30 mil, Grande Petronas Oak's wear layer sits on the thicker end for residential flooring, which is why it stands up well to heavy day-to-day use. The 15mm construction gives it a solid, stable feel underfoot in busy rooms.

What does the plank surface look like?

Up close, the Grande Petronas Oak plank is where the rustic character really shows. The open grain runs long and unbroken, with deep movement down the length of each board, and it is interrupted by large character knots, some with cracked centers and fine checks that read as genuine age. Pronounced mineral streaking cuts dark lines across the honey-gold field, and the figure varies heavily from board to board, so no two planks repeat. Knots land at a moderate density: enough to make each plank distinct, not so many that the floor looks busy. It is a surface built to look weathered and handled, printed in convincing detail over the rigid core.

Quiet enough upstairs or in a condo?

The attached acoustic layer damps the hollow "click" sound characteristic of floating floors. Grande Petronas Oak is quieter underfoot than LVT with a loose pad — both for the walker and for rooms below in multi-story homes.

Is it safe for indoor air?

Yes — Grande Petronas Oak carries GREENGUARD Gold certification, independently tested for low chemical emissions. That matters most for households with allergies, asthma, or young children.

Will this color work in my room?

Grande Petronas Oak is a honey-gold brown with amber warmth, and soft light is exactly where that warmth comes alive. In this dining room there is no direct window light; instead a warm ambient glow fills the space in the evening, and under it the floor turns warm and golden rather than pale. That warmth pairs easily with cream and off-white walls, which keep the room feeling open, and with deeper accents that echo the amber in the floor. If your own room leans cool or north-facing, expect the same shade to read a touch more subdued and muted; a brighter, south-facing room will lift it toward gold. Either way it stays a welcoming, low-drama backdrop for how you actually use the space.
