Seven strokes let you become a master of wooden floors

Remember that these seven strokes are "one touch," "two," "three," "four," "five," "six," and "seven bubbles."
At first touch, the good substrate feels smooth, flat and grainy, and the poor touch feels rough.
Second, the same volume of substrate, good is much heavier than bad.
Thirdly, the cross-section of a good-quality laminate flooring is densely wooded, and the cross-section of a poor-quality laminate flooring is loose and has many blackish impurities. After cutting the wooden floor, the cross-section of a good floor is very clear and has no impurities or voids.
Four smells and smells cross-sections. A nice floor gives off a fresh, woody scent. The poor floor has a rich, pungent nose.
Five grinding, test wear layer: usually sandpaper can be manually polished on the floor surface 10 times or so, to observe whether the surface decoration pattern damage, found that the phenomenon of destruction, indicating that the floor wear resistance indicators do not meet national standards.
Six fight, random sampling board for test spelling, to see whether the joints from the joints phenomenon, touch the joints have no level feel. If so, the quality is poor. Simulation of solid wood is particularly necessary to observe whether the notch splicing process has a wear-resistant layer of protection and whether it is easy to do cleaning.
For seven bubbles, a small piece of wooden floor is soaked in a glass jar to observe whether the water quality becomes turbid and thick and has an odor. If there is, it indicates that the amount of glue on the floor is not high; the water absorption thickness expansion rate of the floor is observed. The smaller the expansion, the stronger the resistance to deformation of the floor is, and the smaller the deformation of the floor is. The clearer and clearer the floor water quality is, the better the water quality is.
