We know wood
In the refinishing business we often spend time speaking to our clients about the specifics of their floor. Every wood species is unique and comes with it’s own characteristics. Like dogs you should consider some time thinking about what hardwood suites you. If you have existing hardwood you’ll want to know what your options are to turn it into your dream floor. Here we’ll help give you some information to de-mystify hardwood flooring.
JANKA HARDNESS SCALE: This is a scale rating the density and hardness of wood. Each species is given a number or rating. The image below shows the difference between Hickory and Pine for example. Your dog’s claws will do a number on pine whereas Hickory will have a better chance to stand up to heavy family use.
FLAT SAWN/RIFT/QUARTERED: The way a tree is cut determines the grain pattern on top. Graf Custom Hardwood does a fantastic job of showing this in an illustration. The majority of woods are plane or flat sawn, however, many herringbone oak floors for example are a mix of rift and quartered instead of flat sawn.
Below are photos of the same species and grade of hardwood but cut differently. You will notice a difference in grain, mineral streaks, knots and wormholes.
WOOD GRADES: You have different species, different cuts and now different grades. There is a difference between a rustic oak and a clean rift & quartered oak, a big difference! Below is an example of a Maple floor in different grades. The choices are clean, select & better, #1 common, #2 common and rustic(or character). Can you spot which is which?
There are many species to choose from so we’ll just cover the most common that we see in our shop.
