American Black Walnut Lacquered 18mm Engineered Wood Flooring

American Black Walnut Flooring

American Black Walnut flooring ranges from warm honey-brown through to a deeper, richer chocolate tone. It varies naturally from board to board, so no two boards look quite the same. Expect real character, including visible knots and grain, rather than a uniform, printed look. This is a warm, statement floor with real depth to it. It’s part of our Timeless 18mm engineered wood range.

This board is lacquered, giving it a tough, easy-clean surface. Scratches will show up more on a lacquered finish than an oiled one. Keep grit and debris off the floor where you can. You can still sand and relacquer it down the line. It just needs a full room job, not a quick spot fix like an oiled floor gets.

American Black Walnut flooring carries a Class 23 heavy domestic and Class 32 general commercial rating. That means it holds up well in busy homes and light commercial spaces. It comes with a 15-Year Residential Warranty.

Before fitting, let the boards acclimatise in the room for at least 48 hours, laid flat. Don’t leave them in a garage or anywhere freezing cold, the room needs to be at normal room temperature. And standing them upright instead can cause them to bow.

Fitting and Cutting

The subfloor needs to be as flat as possible, same as with any flooring. Engineered wood generally has a bit more give than people expect, though. For a very uneven surface, a plyboard overlay or a screed will sort it before you start.

With American Black Walnut flooring, you can float it, stick it down fully, or secret nail it. Floating it needs an underlay underneath, see our underlay range. Going full stick-down, we’d recommend Monosil P adhesive. Sticking it down on a concrete subfloor, you’ll need a liquid damp proof membrane first. On floorboards, ply the subfloor before sticking down.

Secret nailing is another option for American Black Walnut flooring. This hides the fixing inside the joint rather than on the surface. With Tongue-Tite screws, you drive a screw into each board’s tongue at roughly a 45-degree angle. Space the screws roughly every 6 inches, and they pull each board in tight against its neighbour. They’re self-piloting, so there’s no need to pre-drill. A porta-nailer does the same job a different way. It’s a striking tool, hit with a mallet to drive a nail into the tongue at roughly the same angle. Either way, the next board’s groove covers the fixing completely once it’s in place.

A chop saw, jigsaw, or hand saw will all cut these boards cleanly. So American Black Walnut flooring is ready to fit and finish properly, whichever method suits the job.
