First of all, if you are shopping for a cheap flooring option and are tempted by a cheap brand of bamboo flooring, be careful. You are most likely getting a high toxic glue content and a soft floor that will show years’ worth of damage after a few months.
Even if you go for a higher quality brand of bamboo flooring, it is still vulnerable to scratches and dents, and refinishing potential is sketchy at best. If you want to eliminate your floor’s blemishes, you will have to replace it. You just doubled the cost of your bamboo floor.
If that doesn’t sound like your ideal situation, then you may want to reconsider your decision to install bamboo.
