Abstract
A surface covering containing at least one layer containing wear-resistant particles, such as aluminum oxide, is disclosed. Preferably, the wear-resistant particles are present in the outermost layer of the surface covering which is exposed to the environment. A method to improve wear and/or stain resistance to a surface covering is also disclosed and includes adding an effective amount of wear-resistant particles to a top coat layer or outermost layer of a surface covering optionally, with the use of a suspension aid.
