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!
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.
Q: I have installed a Walker Zanger crackle tile which the entire surface of the tile is covered in the white material that the tile is made from. It is a shower stall. I’m guessing the water has penetrated the tile and reacted to it. What are your thoughts?
A: Hello Mike,
A crackle glaze tile requires sealing prior to grouting and then the grout must be sealed after it is fully cured (to be safe) after 72 hours. Then, depending on the amount of usage the shower gets, the tiles must be resealed as part of the routine maintenance program. For a master bathroom shower you may need to reseal every year where as a guest bath shower may be every 3-5 years. The white buildup on the tile’s surface is most likely not particles from the tile’s clay body but it may be grout residue or efflorescence emanating from the thin-set and mortar bed. Hope this helped and thanks for your question!
Q: Is it possible to install your AnTeak Collection on the ceiling? If so, what is the suggested process?
A: Hi Lorraine,
Yes, our AnTeak tile can be installed on the ceiling, just as on walls. Please allow the tiles to acclimate on the location of the installation for 4-5 days prior to installation. This will ensure minimal expansion and contraction of reclaimed teak tile products. For detailed instructions, please visit the following link and download our AnTeak Installation Instruction (add link to installation instruction). Thanks for your question!
Q: What should I use to clean my 6th Avenue ceramic tile?
A: Hi Penny,
Use a pH neutral cleaner manufactured for cleaning ceramic tile. Your grout should be sealed and then, when cleaned, the pH neutral cleaner won’t harm the sealer or grout. If you were to use a cleaner that is somewhat acidic, over a short amount of time, the tile’s glaze may dull and the grout will become etched and discolored. This means that vinegar, which is also an acid, even if diluted in water will cause the same negative outcome. Marble, Travertine, and Limestone are all composed of calcium carbonate, so they will also be etched and become dull if cleaned with that same vinegar and water scenario. Walker Zanger recommends and offers for sale Oceancare’s pH Neutral Tile and Stone Cleaner to help with this problem. Thanks for your question!
Q: I’m interested in the Helsinki Chevron tile for my bathroom and shower floor, but I’m concerned about how slippery it would in the shower since it’s so smooth. Is it rated for bathroom use?
A: Hi Palamy,
The Helsinki Chevron Pattern is fine for your shower walls but for the floor I would use the Helsinki Small Brick, Long Brick, or 1 x 1 mosaic. This way you’ll have sufficient grout joints, using a sanded grout, to provide a finished stone tile surface that will not pose a slip/fall issue even when wet. (Small Brick 4” X 7/8”/Long Brick 6” X 1-1/8”) Thanks for your question!
