5" 實心 PSA INDASA 白色砂盤 (捲)

These discs cut through a fresh coat of water-based polyurethane without any gumming up, which saved me a ton of sanding time. The "C" weight paper backing feels just right—sturdy but still flexible enough to wrap around a sanding block. Exactly what I needed for fine-finish work.

The non-loading grain made a huge difference when I sanded the water-based poly on my kitchen cabinets — no gumming up at all. This roll is exactly what I needed for consistent results without switching discs constantly.

I was skeptical about how well these would work with the new water-based polyurethane I'm using, but they held up perfectly without any clogging. The "C" weight paper backing gives them just the right amount of flex for detailed sanding.
