Security Deposit in Connecticut--Wear and Tear/Depreication and "Useful Life"

For two years I rented an apartment with old, unfinished wood floors. I had a plant that leaked water onto the floor and damaged it. I know I have some responsibility for this, but the landlord is planning to keep my entire deposit ($1175) to repair the floor. Does this sound reasonable?

Again, I'm willing to take some responsibility, but this is a floor that needed sanding and sealing before I moved in and I don't feel comfortable financing the whole project.

Thanks!
