CertainTeed Fiber Cement Underlayment



 

CertainTeed has applied advanced technology - used to produce our acclaimed WeatherBoards™ Fiber Cement Siding - to interior ceramic tile underlayment and backerboard.

These products feature a dense, non-porous surface, making them excellent choices for kitchen and bathroom applications where moisture is a fact of life. The surface and edges are also smoother than those of competing products, for easier installation and neater finished jobs.
