Buying Guide: How Can I Choose The Best Grout For Shower 

Types of grout

Grouts come in four different grades, each with a unique set of applications. In wet conditions, choosing suitable grout is critical to maintaining your tiled surface and the structure beneath it. When it comes to tile installation or grout, you have a choice of using unmixed grout, fine sanding, grout, or epoxy grout.

Non-sanding grout

For tile installations with grout joints less than 1/8″, unmixed grout should be used. Because of its fine texture, pure grout is often used to pave vertical surfaces such as walls and around the tub.

Fine grout (fine sand)

An emery grout should be used for brick installations with 1/8″ to 3/8″ wide grout joints. Grout is the best material for wider joints because it is less prone to shrinkage and cracking in the first place.

Sanding grout (quarry style)

Quarry grout is a more prominent grain sandstone grout used for brick installations with grout joints between 3/8″ and 12″ wide. Quarry grout requires sand to prevent shrinkage and crack at larger grout joints, like fine sand grout. Sand with coarser grains is necessary for larger joints.

Epoxy grout

Epoxy grout is made up of fillers and two epoxy resins. Epoxy grout is ideal for high-traffic areas such as commercial buildings because it is naturally resistant to stains and remains supple, reducing the risk of cracking and chipping. Epoxy grout is self-sealing because of its chemical composition. Unless otherwise specified by the manufacturer, this grout mixture is suitable for ceramic and glass tiles. It can be used with natural stone tiles, but it must be sealed first. Epoxy grout manufacturers have addressed previous formulations that fade when exposed to natural UV rays and cause pinholes in the grout surface during application.

Waterproof ability

Water can co-exist with water-resistant grout but is impermeable. This is a huge step forward, as having this property in your grout helps prevent mold from forming and shortens the life of the grout, making it ideal for use in the bathroom or kitchen. Water-resistance is often a feature of cementitious grouts.

Resistance to fire

It is generally recommended to take fireproof grout to avoid dangerous fire. While it’s less likely that you’ll catch fire in your bathroom, you should choose a fireproof grout as a precaution. Fire-resistant grouts are commonly used in kitchens and other areas where fires can occur because they can prevent the fire from spreading.

Non-toxic grout

While using non-toxic grout, your hands will not be affected. It will also never emit any harmful fumes. The use of non-toxic grout glue is always preferred because the chemicals used for grout today are often very toxic.

Color of grout

Color grout glue sold on the market today has many different colors. You must select them carefully based on your requirements to be compatible with the environment in which they are used. You don’t want your bathroom tiles to look filthy, especially if you’ve spent money on suitable grout.

Resistance to stains

Another issue to think about before buying a grout is stain resistance. Stain-resistant grout is becoming more and more popular as new technologies emerge. As a result, whatever falls on it won’t matter. The reason is that the tiles and grout in your bathroom will keep it looking new.

This ensures that your tiles will last a long time and stay in good condition. Epoxy grout resists stains and keeps your glass shower door clean.

Joint width

It is a measurement of the distance between two adjacent joints. Unmixed grout of any kind, whether cement or epoxy, is used for connections less than 1/8 inch wide. Sand-mix grout is used for widths beyond this.

Minimize drying time

The drying time of the grout should be as few as possible. However, this time you will be able to remove any excess grout that has accumulated on the tile’s surface.

Cleaning and maintenance grout

Grout can begin to lose color uniformity and shine after years of exposure to stains and dirt. You should choose a grout that requires little maintenance. If not, you should use a regular degreasing chemical to freshen it up.

Otherwise, choose grouts that require little care and maintenance so they can continue to shine even after many years without much effort.

Resistance to mildew

Mold can grow on the grout surface in the bathroom if there is constant water in it. For homeowners, this is a significant problem. It takes a lot of work to prevent and remove mold. The anti-mildew grout will keep your bathroom looking clean while staying hygienic.

What is the difference between sanded and unsanded grout?

Sanded grout and unsanded grout are very different.

First of all, there is a difference in thickness between these two types of grout. Compared with unmixed grout, rough grout is thicker and more durable. This is large because unmixed cement grouts shrink faster than sand mixed grouts, resulting in poor adhesion.

Second, they also have the difference in vertical to choose between the two categories. Because it is tacky and more accessible to putty, unmixed grout works better on vertical tiles than sanded grout.

The third point is related to the difference in harmful effects of each type of grout. Grout can often act like sandpaper, causing damage to smooth tiles. Unsanded grout does not have this problem.

Finally, their sizes are not the same. Because it is smooth and easy to apply, sand-free grout is ideal for joints less than 1/8 inch wide. Sand-mix grout provides perfect adhesion to front joints wider than 1/8 inch.

Can silicone replace grout?

Silicone can be used as an alternative to grout on any surface with corners or bends. Grout can only be used on the same consistency as silicone, and silicone tends to shrink. It also provides an extreme level of stickiness.

So instead of using silicone, you should use grout for your bathroom walls and floors’ most effective and lasting results.

When it comes to grout, how can you tell if it’s sealed?

Visual inspection can tell you if your grout is sealed. It has been adequately sealed if water particles or oozes come out from the grout. If your grout is darkening or absorbing water, it has not been filled, or the existing sealant has worn down and failed to preserve the grout. You will then need to reapply so that your grout is completely sealed for maximum effectiveness.
