I've seen two common types of edge finishes for laminate flooring. Since I'm not familiar with the actual trade terms (feel free to point these out), I'm going to dub them: flush fit and V-fit. I call flush fit is the planar one, where the edges attempt to form a continuous & seamless surface between planks. The V-fit is the one where the planks are slightly grooved on the edges so that adjacent planks form a V-shaped notch. As far as I can tell from the advertising material, the main purpose of this notch is to give a 3D impression of actual wood planks.
I'm wondering what's the best edge shape for maximum spill resistance. The manufacturers are rather mute on this. The V-shaped notches look like an obvious place where liquid would gather. On the other hand, the notches could be well sealed... and I've seen "aqua safe" boards from Pergo that use V-edges. The flush edges could actually draw in more liquids through capillary effect if the fitting isn't tight. Is there any comparative experience or data on this edge shape issue as it relates to spill resistance? (As an aside: I'm well aware that some manufacturers like Egger advise to use (and even sell their own brand [STRIP-EX] of) glue for increased spill resistance between boards.)
