Surface finish quality is difficult to judge from a product photo alone, since gloss level, coating thickness and edge sealing all affect how a large dry erase board performs in practice, not just how it looks in marketing material. Requesting a physical sample panel, ideally a genuine offcut from the same production batch rather than a curated showroom piece, gives a far more honest impression of how the finish will actually behave once installed. Testing a range of marker types and colours directly on that sample, including a cheap marker likely to end up in daily use, reveals more about real-world performance than any specification sheet. It is also worth asking how the specific finish has performed on installations that are several years old, since this is where the difference between a genuinely durable surface and one that only looks good when new becomes obvious.
