What Is the Difference Between Sanded And Unsanded Grouts?

The difference between sanded and unsanded grout are as follows-

What Is the Difference Between Sanded And Unsanded Grouts?

1. Thickness

Sanded grout is much thicker and durable than unsanded grout. This is mainly due to the fact that unsanded, cement-based grouts shrink faster than sanded ones, and does not ensure proper adhesion.

2. Vertical Tiles

Unsanded grout works better on vertical tiles than sanded ones, because it is stickier and easier to spread.

3. Damage

Often times, sanded grout can work like sandpaper and damage smooth tiles. There is no such issue with unsanded gout.

4. Size

Unsanded grout is perfect for joints, which are less than 1/8 inches wide because it is smooth and easy to apply. Fore joints wider than 1/8 inches, sanded grout provides the perfect adhesion.

Types of Tile Grout

There are mainly 4 basic types of grout. Each is mentioned below –

1. Unsanded Grout

This type of grout is made by mixing cement, water, and non-sand particles. They are best for smooth surfaces and grout lines less than 1/8 inches wide.

2. Unsanded Grout

This type of grout has sand mixed into it. It does not shrink easily and is, therefore, best to be used in lines that are wider than 1/8 inches.

3. Epoxy Grout

Epoxy grout is highly stain-resistant, and best for places that come in touch with water every day. It usually does not need any sealer.

4. Quarry Type Grout

This grout is made with a coarse type of sand and is best for grout lines that have a width between 3/8 inches to ½ inches.

Frequently Asked Questions (FAQs)

Below are some of the most commonly asked queries regarding tile grouts:

Q. What is the best grout to use in a shower?

It is best to use Epoxy Grouts in a shower, as they are less susceptible to staining. They are also made from resins and fillers that help them work like a sealing adhesive.

Q. Is grout waterproof in showers?

All grouts provide water resistance that disallows water to penetrate through them. Some grouts are also waterproof. But we still recommend you to install a waterproof membrane just below the tile bonding mortar as close to the tile as possible.

Q. Can I use silicone instead of grout?

Silicone can be used instead of grout, but only on any corners or bends on a surface. This is because grout can only be used on the same plane, and silicone is prone to shrinking. It also offers a degree of adhesion that is not necessary.

Q. Is epoxy grout better than regular grout?

Though regular cement are quite good in their own right, they just aren’t as reliable as an epoxy. That is mainly due to the added benefit of stain resistance you get on the latter. Since they are made from made from resins and fillers, they can also operate as a sealing adhesive.

Q. Does epoxy grout need to be sealed?

No. While other types of grouts need to be sealed, that is not the case with epoxy grout because they are highly water resistant and seals itself as it dries.

Q. How can you tell if grout is sealed?

Knowing whether your grout has been sealed or not can be done by simple eyeballing. If the water beads or flows from the grout, it has been sealed properly. However, if it darkens or absorbs the water, then your grout has not been sealed or the old sealer has broken down and is no longer protecting the grout.
