Ask Bob. Rectified Porcelain.

21 collage

 

Q: I am interested in a 21 Cemento porcelain tile floor for my high rise condo in San Francisco. I have visited your showroom in the design center in San Francisco where they have the 24″ x 47″ tiles with very tight grout lines installed on the floor in a straight grid pattern. This is the look I want. The designer helping me said this isn’t possible because porcelain tiles bow in the middle and must be installed with a 30% offset and wider grout lines. She suggested that I contact you for technical assistance. Very discouraged, I took to the internet, and now know about “lippage” and rectified vs. non-rectified tiles. Are these 21 tiles rectified? Should I give up on this beautiful floor? I don’t like the offset look. All the pictures on your site show the tiles in a straight grid pattern. I would love your advice. Thank you!

Best, Dale

 

A: Hello Dale,

Your contractor would be correct in her statement if you were to install our 21 Cemento Porcelain Tiles using a running bond pattern.  However, a straight set grid pattern will not present a problem with a 1/16′ grout joint width because the apex of the bowing in each tile will align with the bowing of the adjacent tiles on either side.  As a result, lippage will not be an issue.  Regarding 21 Cemento tiles being rectified, they are that way because they are uniform in facial dimension.
