I saw tiete rosewood engineered flooring, which is very hard (hardness of 3200). Is it a good flooring for the whole house including the kitchen? Is it photosensitive like brazillian cherry, which will change color obviously with sun exposure (although double pane patio door or window is closed) ?

Another general question, will the surface paint and coat of the hardwood floor wear off after 5-6 years?

Thank you very much.
