Wood flooring is not required to meet specific hardness standards because each wood species has unique features and hardness.

Hardness is measured on the Janka Hardness Scale. The Janka hardness test measures the amount of force required to push a steel ball with a diameter of 11.28 millimeters (0.444 inches) into the wood to a depth of half the ball's diameter. The result is expressed in pounds-force (lbf). If you're installing a floor in a high traffic area or you have large pets, you'll want to look at a floor with a higher Janka hardness rating because a higher hardness rating means that the floor will be more resistant to scratches, dents, and other types of damage. However, hardness isn't the only factor that goes into the durability of a floor. Other factors are the type of finish used, the amount of gloss, the number of coats, and even the grain of the wood. It's important to understand that while hardwood floors are tough, when it comes to indentations NO FLOOR is impervious to damage. The standard in the wood flooring industry is measured by comparing a given species hardness to white oak, which has a Janka rating or 1360. By comparing to domestic white or red oak you can tell how hard or soft a floor is. For species like Santos Mahogany (Janka rating 2200) or Brazilian Walnut aka Ipe (Janka rating 3680) which feature far denser grain patterns, and are thus harder and more resistant to some damage than species like North American Cherry (Janka rating 950) or Black Walnut (Janka rating 1010).

Yes, if it is a floating hardwood floor. You can find them as click together or where the seams are glued. The downside is that often these floors are hard to repair unlike a solid wood floor.

How to Estimate Flooring Supplies?

Estimating flooring supplies for commercial and residential flooring installations requires knowledge of the flooring system that is being installed. Certain flooring such as vinyl sheet and resilient flooring require additional square footage allowances for waste. Some brands of manufactured hardwoods cannot be installed directly on a concrete sub floor without a moisture barrier, and some ceramic tile floors require a slip-sheet as part of the substrate system.These are a few examples of the many considerations that need to be addressed in order to provide a competitive estimate for the purchase of flooring supplies. When an estimator puts the tape measure to a set of stairs, the dimensions that are recorded will be the width of the tread, the height of the riser and the width and run of the staircase. For one who does not understand how these dimensions translate to the flooring estimate, the best thing to do is apply for a position as an apprentice estimator. This way it’s possible to learn and understand the many considerations for the different types of flooring, and at the same time, avoid attaching undue costs to an estimate for flooring supplies.In addition to square footage for materials, an estimate for flooring supplies will include mastic for adhesive applications such as sheet flooring and some brands of manufactured hardwood flooring. Adhesives are produced in water base and petroleum base solutions, and there are instances where one of these will be preferred over the other. Where water based adhesives can be used, the type of slip-sheet will be less expensive, since it doesn’t need properties that resist a harsh adhesive.A comprehensive estimate will specify the type of adhesive. The amount of adhesive that is required for a flooring installation should be at least 15% over the total square footage of the flooring that has been shipped for installation. This is known as allowable waste and it is essential since every installer has a slightly different method of installing certain flooring. Estimating flooring supplies should be left to the professional, experienced estimator.
