When going through the process of purchasing and installing wood flooring for your home, you should consider signs of well-installed high-quality wooden flooring to increase your satisfaction in the end. First of all, consider that flooring can be made of different woods classified as hard or engineered. Quality solid or engineered wooden flooring is generally made out of wood which comes from deciduous trees like oak, maple, mahogany, teak, walnut, cherry, and more. Secondly, the way a wooden floor is constructed can contribute to its beauty, functionality, and how long it will last. The sturdiness of floors will tell you a lot about its quality. Thirdly, sanding, staining, and finishing are part of the process, and neglect at any of these stages can affect the overall quality of flooring. Sanding is the first step in the finishing process. Good floors will be smooth, so there are no rough patches when you run your hand over it. Also, properly sanded wood will take the stain nicely. By the way, when you look for wooden floor good stains enhance the natural beauty of wood and add color and character. High-quality staining will be without any dark spots and be the same tone. Finally, a high-quality finish is smooth and free of rough spots, dust specks, or bubbles and reduce the chances of swelling or shrinking of floors. Opposite to high-quality finished floor, poorly finished floor will have a rough surface, a very glossy or cloudy surface that hides the wood grain, scratches, dents, or dust specks, dull spots indicating missed areas. Good luck.
