: In new home, builder said that there would be a felt underlayment under ceramic tile. Tile installed using mud over concrete slab. Is that satisfactory or should I hold them to their promise of a felt underlayment?
THE UNDERLAYMENT YOU SPEAK OF IS VERY EXPENSIVE TO AN INSTALLATION AND ONE RESIDENTIAL APPLICATION USSUALLY WAY TO MUCH OVERKILL ... THAT TYPE OF MEMBRANE IS USSUALLY MEANT ON LARGE COMMERCIAL JOBS WHERE CONCRETE FLOORS TEND TO CRACK OUT ALOT.
IN A HOME AND ON A CONCRETE FLOOR YOU SHOULD NEED NO MEMBRANE UNLESS THE ENTIRE AREA IS CERAMIC ... LIKE OVER 300 SQ.FT. IF ITS NOT THIS LARGE I WOULD SAY IT IS STILL OK TO NOT USE IT. BUT IT DEPENDS ON WHAT YOU WERE PROMISED AND WHAT YOU PAID FOR. IT IS A IMPROVEMENT UPGRADE TO USE IT NONETHELESS. YOUR CALL BUDDY. IF YOU WERE PROMISED IT, I WOULD DEFINATELY DEMAND IT...BUT THATS JUST ME.
