Grout Widths Because unsanded grout can also be used for 1/8-inch lines, between the two it is recommended that you use sanded grout. Unsanded grout is best for grout lines as wide as 1/8-inch and down to 1/16-inch.

How should you fill spaces between tiles of the space is larger than 1 8?

If your gap is smaller than 1/8 inch in width, use regular caulk; fill gaps larger than 1/8 inch with a sanded caulk. Make sure the gap is clean and dry, then squeeze a thin, even bead of caulk into the space. To get the best coverage, cut the tip of the caulk tube so the bead that emerges completely fills the gap.

What size grout joints should I use?





TCNA recommends a minimum 1/8″ grout joint for rectified tile and minimum 3/16″ grout joint for calibrated tile. They also suggest adding to this width the amount of edge warping on the longest edge. For example, if the edge warping of a rectified tile is 1/32″, the minimum grout joint is 1/8″ + 1/32″ = 5/32″.

Can I use unsanded grout on large gaps?

It’s more resistant to grout cracking and shrinkage which makes it the best for large gaps and wider joints. Unsanded grout is better used in joints that are not more than 1/8-inch-wide. It has a smoother texture and clings well to vertical surfaces.

What’s better sanded or unsanded grout?

Sanded grout is the go-to choice for most interior flooring installations. This is because it is more durable than unsanded grout, can handle foot traffic, and is usable for larger tile joints.

How do I choose grout spacing?

As a general rule, floor tiles should have grout lines of 1/8 inch or larger, depending on the type and size of tile. Special types, such as slate or quarry tiles, often do not have edges uniform enough to work with tight spacing. These tiles usually are spaced with grout lines 3/16 inch or wider.

What is the standard grout width?

Actual finished grout spaces will vary from 1/8″ to 1/4″ if 3/16″ spacers are used. If smaller spacers like 1/8″ are used, it will accentuate the size difference of handmade tile. Finished grout lines will vary from 1/16″ to 3/16″. Note that using the smallest grout possible will increase installation time.

How many spacers do I need?
