Security Deposit Normal "wear and Tear" or Damage

[Jennifer Koester]

Hi,
My lease with my tenants is up in two months. When my tenants moved in, the house was newly painted and floored. Can I hold back from their security deposit the cost to re-paint all the scuff marks on the walls and water damage to the pergo wood flooring that they will leave behind or, is this considered normal "wear and tear"?
