Common Tile Questions

Common tile questions

Why is there so much shade or size variation in my tile?

When purchasing tile, it is important to select the same size, shade and JO (job lot) numbers on the

carton. Multiple lot numbers will cause varied sizes and/or shades. This information is normally found

on the side of the box. It is common to have multiple lot numbers on the shelf. If you need more than a

pallet, please you ask your Lowe's store to order directly from the manufacturer. This tile is made in

USA, so it's not a problem. Expect about a week for it to get to the store, but there is no extra cost.

Always open several boxes and lay out the tiles to ensure that you have the desired look before you

permanently set them with mortar. If you see that there is an undesirable variation, please reference

the size and shade information on the side of the carton to ensure that you’ve received the sale job lot.

Is a grout line recommended or needed?

Yes, a minimum grout joint of 3/16 (5mm) is recommended for pressed tile. If you’re installing with a

staggered tile placement, we recommend using a 30% offset. If you must use a brick pattern with ½

offset tile placement, a larger grout joint is recommended to reduce the visibility of size imperfections

that are standard in pressed tile (minimum ¼” grout joint with ½ offset brick pattern).

With any porcelain or ceramic tile that is pressed there will be slight variations in size, in accordance

with ANSI and ASTM standards. As tiles are baked in the kiln, the finished product can have slightly

varied results.

Rectification is the process of mechanically trimming the sides of tile. This process allows for much

thinner grout line (3mm); because all tiles will be trimmed to a precise size. Thus, rectified tiles are

often more expensive.

What trowel size should I use?

Check the grout and mortar you will be using. On the back of the package it should list towel sizes

needed based on the size of the tile. For example, most tiles that are 16 inches or larger will need a ½”x

½” trowel. Make sure the proper thinset mortar coverage is also met by the trowel size. Dry areas such

as floors, fireplaces, and accent walls require a minimum coverage of 85% for the back of the tile. While

wet areas such as showers require a minimum coverage of 95%.

How do I install planks or large format tile?

Planks (such a 6x24, 6x36 or 8x48) will need to be installed at a 1/3 or 33% offset instead of the

traditional 50% brick layout. This is to avoid noticeable lippage in the tile. The Council of North America

allows for warpage in all tiles. Visit the TCNA website for more information.

What color grout should I use? Selecting a grout is personal preference. Your local Lowes will have several color options to meet your project needs. Choosing a color that blends with the tile is most common, however choose a grout color that is different from the tile will add some pop to the design. Can I install my tile outside? In general porcelain tile can be installed outside and is made to withstand freeze and thaw cycles. Most porcelain tile is also impervious to water.

How do I clean the tile? When cleaning tile, first you need to make sure the surface is free of debris, so a good vacuum or sweep is best. Once the floor is free of dirt or other particles you can use warm water and a mild soap to clean the floor. A mop or rag that is nonabrasive is best to use. Make sure to change the water frequently to avoid leaving a cloudy film on the tile. If the soap doesn't work, you can use vinegar and water with a 1 to 2 ratio, so 1 cup vinegar with 2 cups warm water.
