Hello Sharon and thank you for your question.
The TrafficMaster Allure Hickory Resilient Vinyl-Plank Flooring can be installed over most existing floors including wood, vinyl, linoleum, ceramic tiles, and concrete. All subfloors must be sound, solid, and have little flexibility.
Review pages 2-3 of the Installation Guide for specific information about existing flooring surfaces and take corrective action (if required): http://www.homedepot.com/catalog/pd...
Best wishes on your project.
