Forget about hardwood refinishing for a moment. For right now, imagine that it's Sunday morning. The warm sun is peaking in through the window and over the faint sound of birds chirping you can hear your family getting ready to start their respective days. Junior is eating breakfast and preparing for his big soccer game, and while trying to put his cleats on at the table he spills his glass of milk.
You make a joke, you both chuckle and together you clean up the mess. It sounds like a beautiful and relaxing morning, doesn't it? Not for your hardwood floors. UV light and radiation produced by the sun can come in through the window and bleach the vibrant colors out of your hardwood.
This can cause them to look dull and worn, instead of lustrous and new. Sharp points like cleats, especially when coated with sand or mud from a soccer field, can scratch the protective coating on your floors and allow water and dirt to infiltrate and damage the wood.
