Grout that is used for tiles acts like a mortar that binds the tiles together. Tile grout also keeps moisture out and helps keep the tiles at a certain distance apart. Grouts available when you buy sands Australia can be classified into two basic types: sanded or unsanded. The right choice for your tile job depends on the kind of tiles you’re installing and the size of the joint between them.
Flooring and tile specialists have intimate knowledge about the difference between sanded and unsanded grout. Here is their take.
Sanded grout is more durable and thicker than unsanded grout
Sanded grout is your standard grouting material with added aggregate sand material. The added sand makes sanded grout more durable than its unsanded counterpart for one unsanded reason: shrinkage. Cement-based unsanded grout tends to shrink when it dries and pulls away from tiles. Sanded grout won’t shrink so much. This is because the sand and cement bond and lock in place when dry. For tiles used for heavy foot traffic, such as in bathrooms, sanded grout should be used, as well as tiles that only need to be 1/8 of an inch apart. Sanded grout is also resistant to cracking.
Unsanded grout is a better hold for vertical surfaces
Unsanded grout is extremely sticky and can easily spread onto vertical surfaces. As the grout dries, it has no issues even with shrinkage. Since vertical tiles are spaced between 1/8 and 1/16 of an inch, shrinkage is not an issue nor with the durability of the tiles. There is no problem with cracking since vertical tiles have no pressure applied to them.
Use unsanded grout for smooth tiles
The harsh aggregate sand material in sanded grout can damage delicate tiles such as soft stones, limestone, marble, and granite. Unsanded grout works better with these fragile tiles, regardless of joint spacing.
Use unsanded grout for joints smaller than 1/8 of an inch
It’s not good to use sanded grout for precision joints smaller than 1/8 of an inch. It’s hard to work with sanded grout in tight spaces. The bulky sanded grout will prove cumbersome and difficult to squeeze into small tile joints. Sanded grout may be durable, but it won’t matter if you can’t press it into your tile joints correctly. When sanded grout is forcefully used for tight joints, it leaves many “pinholes” that are visible and a sign of shoddy workmanship.
