Need advice regarding Marble Flooring Description

Hello.
I am looking for some kind of product to make a section of Marble (http://www.lightemprador.com) flooring non-slippery.
This section is located in a turn-style doorway.
This product CANNOT interfere with the guards on the bottom of the doors which create a seal.

Any assistance will be greatly appreciated.

Thank you.
Marta
