![]() The weight of the material will keep it from shifting, and the walls will hold it in place. With a floating floor, the pieces click together to create one large puzzle that can be installed right over an existing floor (assuming it’s flat and smooth). That depends on whether the material can be installed as a floating floor or should be nailed or glued into place. This gives us information on what can happen to a section of flooring that gets more sunlight than the rest of a room over time. We evaluate the potential for fading by exposing part of a sample of flooring to UV rays for two weeks straight, and then compare the exposed portion to an unexposed portion. The more a product swells, deforms, softens, or delaminates in those two tests, the lower its water-resistance score. We take another sample of the same flooring and completely submerge it in a bucket of water, again letting it remain overnight. We spill water on a flooring sample’s surface and allow it to sit overnight. The higher the drop before damage becomes evident, the better a floor’s dent-resistance rating.Ī floor’s water resistance is key, and manufacturers are continually trying to improve their products’ impermeability. Our testers drop the weights from progressively higher points, examining the flooring for visible denting after each drop. To test a floor’s resistance to denting, we drop a heavy, blunt weight that has the same impact as a large can of tomatoes, plus objects that are smaller, lighter, and pointier that serve as proxies for kitchen utensils. ![]() We test wear resistance by subjecting a 6-by-6-inch sample of each flooring material to an abrasion machine fitted with a fine sandpaper disc, periodically assessing each sample for signs of visible wear.
