Flooring batch shade mismatch: why boards differ and how to blend them

Same decor, same shop, different pack, and a visibly different shade on the floor. The cause is the batch number: flooring decors are printed in production runs, and colour, gloss and embossing drift a little between runs. Within a batch, boards match; across batches, "the same" decor can be a half-tone apart. Here's the check, the blend, and the purchase habit that ends the problem.

The two-minute check (do it at buying time)

Every pack's end label carries a batch/lot code near the barcode. At the till or the delivery door:

1. Check all packs show one code. Retail stock gets mixed on the shelf, so two batches in one trolley is routine, not bad luck.
2. Mismatched codes? Ask stock for matching packs, or plan to blend (below), and decide that now, while swapping is free.
3. At home, before laying day: pull boards from different packs and compare in daylight, laid flat, because gloss differences show at raking angles that shop lighting hides.

Blending mixed batches so nobody ever sees it

A shade difference between batches is small and uniform, which makes it invisible when scattered and obvious when zoned:

• Open all packs and work from three or four at once, drawing boards in rotation. (Good practice even within one batch, since decors repeat their print every N boards, and drawing from one pack at a time can tile identical boards next to each other.)
• Distribute both batches across the whole floor, not "batch A until it runs out, then batch B", because that's how a floor gets a tide line halfway across. If you're in that situation mid-job, the recovery options are in ran out of flooring.
• Keep noticeably different boards away from the window wall and the main doorway sightline, where raking light is harshest, the same placement logic as board direction.

Blended this way, a half-tone batch difference is genuinely undetectable. Floors are noisy surfaces, and the eye reads distributed variation as decor character.

Buying so batches never matter

The batch problem only bites floors bought in instalments: a first order, then a top-up weeks later from whatever run is now on the shelf. One purchase, one batch, no problem. Which makes batch safety a quantity accuracy problem:

1. Get the amount right the first time. Measure properly, use the pattern's real waste, or lay the room out in the designer for an exact board count.
2. Order everything at once and check the codes at delivery.
3. After the job, keep two or three boards from your batch, the only guaranteed-match repair stock that will ever exist for your floor.

An extra unopened pack from your own batch, returned later, costs a restocking trip. A missing pack from a vanished batch costs a tide line or a threshold you never planned. Round up.
