The prefinished hardwood floor is sealed with multiple coats of finish at the factory. The finish coats typically contain aluminum oxide, the second hardest substance next to diamond, to provide a hard-wearing protective finish. Unfinished flooring must be finished on site after installation takes place. Aluminum oxide cannot be used in the finish on site because the longer drying time causing the aluminum oxide particles to sink to the bottom of the finish. Site-finished floors usually are better at protecting against above floor moisture.
It is best to order about 5 to 10% more than you think you need to make sure there is enough. Take a good look at the room layout and consider your skill level in hardwood floor installation before making a final decision. You will want extra in case of boards that arrive damaged or are damaged during installation. It is also a good idea to have some extra boards for future repairs.
It is not recommended to use a solid hardwood over a concrete slab because of the swelling and contracting caused by excessive moisture. Using an engineered hardwood is the best way to install over a concrete slab because it is much less likely to swell and contract. Thin profile solid hardwood (5/16” thick) can also be installed over concrete.
While it is true many home owners who have hardwood in their homes also have pets, this type of flooring can be scratched or dinged by pet claws. A lot also depends on the type of the pets. Obviously, two Great Danes will have a bigger impact on a hardwood floor than a Toy Poodle.
If pets will be inside, it is best to ensure that pet claws are kept trimmed. And, it is extremely important to clean up any “spills” immediately as these can permanently stain the wood.
Consideration should be given to the species of the wood, as some species are harder and more durable than others.
To acclimate the hardwood flooring, leave it inside the room it will be installed in, with the boxes open, for at least 5 to 7 days. This way it gets used to the conditions in the room before being used. In rooms where there are extreme humidity issues, it may be necessary to install a system such as a humidifier or dehumidifier to control the environment in the room.
An acceptable moisture content runs anywhere from 4 to 18% depending on a variety of factors including the species of wood, where the wood floor is installed geographically, and the time of year. As a result, most wood used for flooring is kiln dried to 6 to 9% moisture content to assist in keeping it from getting so wet it contracts and so dry it shrinks.
