What Happens if You Use Mortar Instead of Grout?

In tile installation, mortar and grout serve completely different purposes. Although they are made up of similar materials, the consistency is different for each.

Mortar and grout are both integral parts of the tile installation process, and each has its own specific role. Although mortar can be used in place of grout, or vice versa, it’s generally not recommended.

Mortar is a thick, heavy paste used to adhere tiles to walls and subfloors. Besides filling gaps between tiles, it also serves as a void filler. Upon drying, mortar provides a strong, durable bond between tiles and surfaces. Mortar is typically made from cement and sand, and it comes as a powder that needs water to mix. In contrast, grout is a cement-based powder mixed with water and color pigments.

Having a good bond between the mortar and the tile is important to prevent the tile from coming loose. If grout is used in place of mortar, the bond may not be as strong, which could lead to tiles coming loose and eventually needing to be replaced.

Grout, however, is a much thinner material used to fill joints between tiles. As soon as the mortar has dried, grout is applied to prevent water and dirt from getting behind the tiles. Grout is available in a variety of colors and can also be used to create a variety of design effects.

Additionally, grout expands and contracts as needed to prevent cracks. However, mortar isn’t as flexible and can crack if the surface it’s adhered to moves.

For these reasons, it is generally recommended that mortar and grout be used as intended during the tile installation process. Using one in place of the other can lead to subpar results and may eventually cause problems.

Is It Better to Clean, Replace, or Re-Grout My Tiles?

You may be wondering whether you should clean, replace, or regrout your tile in order to get them looking good again.

Here we provide a few key points that may help you assess your tile and grout.

A Good Cleaning

Cleaning tile and grout is always a great first option to try. They should be regularly cleaned to prevent damage. Tiles and grout can be cleaned with a mild soap and water solution or a commercial tile cleaner. After cleaning, rinse the area thoroughly. Leaving chemicals present may cause excessive drying-out or may attract dirt and grime.

If your tile and grout still look grungy and gritty after cleaning them, you may consider hiring a professional to assess them. They may require special cleaning equipment and tools to blast away the dirty build up.

When should tile and grout be replaced?

Although tiles and grout can be durable and long-lasting, they are not invincible. With time, tiles and grout lines can become cracked, chipped, or otherwise damaged. Knowing the signs will enable you to make an informed decision.

If there are tiles cracked or chipped, they are no longer providing the same level of protection as they did in the past. Cracks and chips can cause the tile to become vulnerable to water damage, which can result in mold and mildew growth. In addition, cracked or chipped tiles pose a trip hazard.

Grout seals the tile and prevents water from leaking through. If the grout is damaged, water can seep through, resulting in mold and mildew growth. Furthermore, damaged grout can become a trip hazard.

In the event that the tiles are discolored, it may be necessary to replace the discolored tiles. Over time, dirt, dust, and other debris can cause tile and grout to discolor. While discoloration does not necessarily indicate that the tile or grout has been damaged, it can be unsightly. Before making a definitive decision, be sure to first have an experienced tile and grout cleaner look at them to see if they can be saved. Sometimes all they need is a professional cleaning.

A professional can assess the damage and determine whether it is necessary to replace the tile or grout if you are not sure whether it is time to replace them.

When your grout is cracked, crumbling, or otherwise in need of repair, the grout will need to be replaced. You can either do this yourself or hire a professional to do it for you. The best approach is to remove loose and damaged grout prior to apply new.

Can You Put New Grout Over Old Grout?

If your grout is starting to crumble or piece of it are coming loose, you may be wondering if you can simply put new grout over the old.

New grout Should Not Be Applied Over Old Grout, Here’s Why:

New grout should not be applied over old grout as the newly applied grout will not adhere properly to the old grout. The new grout will simply sit on top of the old grout, will not bond to it, and eventually separate from it and peel or flake off. Despite using the same color grout as the old grout, the new grout will appear lighter in color since it is new. As a result, the stains on the old grout will stick out like a sore thumb.

What To Do Instead

If the grout is cracked or crumbling, you’ll need to remove all of it and start from scratch. You can remove grout with a grout removal tool or a multitool with a grout removal attachment. Once the grout is removed, you can clean the area and then apply new grout.

So, while you can’t put new grout over old grout, you have some other options. If the grout is simply stained, a good cleaning may be all that’s needed. If the grout is cracked or crumbling, you’ll need to remove it and start fresh.

Do Tiles Need Grout?

Among the most common questions when it comes to tiling is “do tiles need grout?” The short answer is yes, tiles do require grout. The importance of grout can be attributed to two main reasons. First, grout provides structural support for your tile installation. The second benefit of grout is that it seals the joints between tiles and prevents water from seeping in and damaging your tiles or the substrate beneath them. If tiles are not grouted, they will rub against each other and may chip faster. If tile is installed without grout they will not be sealed and moisture will get in between them and cause damage to the substrate.

Is Grout Waterproof?

The short answer is “it depends” on whether the grout is sealed. If the grout has been properly sealed or is a grout type that has a built-in sealer, then the answer is yes, it can be considered water resistant. Note that we used the word water resistant and not waterproof. That’s because nothing is completely waterproof.

Grout without a sealer:

Concrete, mortar, and grout are all porous materials. Whenever they are used in areas with water, they can absorb water and become saturated. It may lead to several problems, including:

Material deterioration

Mildew and mold growth

Discoloration and staining

Damage to the surrounding area

Water-resistant Grout

In any area where water is present, the options are to either seal the grout or use a water-resistant grout. A water-resistant grout is made with an agent that prevents water from soaking into it. A good example would be an epoxy-based grout. Epoxy grout have resin agents that help resistant water absorption.

A water-resistant grout is ideal for use in showers, bathrooms, kitchens, and other areas where water is present.

Applying Sealer to Grout 

Not all grout is water-resistant. In order to prevent water from soaking into the grout, it is necessary to seal the grout. Grout should be sealed after installation and before exposure to water.

Sealing grout is a simple process. The area must first be cleaned and free of debris. The sealer is then applied to the grout using a brush or roller. After the sealer has been applied, it must be allowed to dry and cure.

Grout can be sealed using a variety of different sealers. There are advantages and disadvantages to each type of sealer.

The most popular type of sealer is water-based. Water-based applies easily and dries quickly. It should be noted, however, that they do not penetrate the grout as deep as a solvent-based sealer will.

A solvent-based sealer is more durable than a water-based sealer but they are more difficult to apply. Solvent based sealers also emit VOCs and may have a strong order during installation. They are tricky to apply and unless one has experience with them, it should be left to professionals to apply.

How Long Does Grout Last?

Grout is a very strong and durable material, but it is not indestructible.

There are several factors that influence the lifespan of grout, including the type of grout used, its quality, how well it is installed, and the amount of traffic the grout will receive.

For example, epoxy grout is much more durable than cement grout, so it will last for a longer period of time. The grout will need to be replaced sooner if it was installed poorly or if it is located in an area with high foot traffic.

Grout typically lasts for 10 to 15 years before it needs to be replaced or restored.


Why Does Grout Fall Out?

Cement-based grout fills in the spaces between tiles. It is usually composed of a mixture of water, sand, and cement. When the grout sealer fails, the grout can become cracked and crumbly, and eventually fall out completely.

There are several reasons why this occurs. As a porous material, grout requires maintained sealer protection. When sealer fails, grout can absorb water and other liquids. As a result, it may expand and contract, leading to cracking. The unprotected grout is also susceptible to mold and mildew growth, which can cause it to deteriorate. Lastly, grout can break down and crumble as a result of regular wear and tear.

Unfortunately, many homeowners are unaware that grout needs to be routinely assessed to ensure the sealer is still working. When the sealer isn’t checked over a decade or more, it will thin down and fail. The grout itself will fail soon after.

Whenever you notice that your grout is cracking or crumbling, it’s best to address the issue as soon as possible. Otherwise, the problem will only worsen. Although you can attempt to repair the grout yourself, it is often best to hire a professional to do the job. In order to fix the problem properly, a professional will possess the necessary tools and experience.

How Do You Get Grout White Again?

If your grout is starting to look a little bit off-color, don’t worry – there are plenty of ways to get it looking white and new again! Here are a few of our favorite methods:

1. Use a grout whitener. You can find these at most hardware stores, and they’re basically like paint for your grout. Just apply the whitener with a brush, let it dry, and voila – your grout will be good as new!

2. Mix up a grout cleaning solution. If you don’t want to use a commercial whitener, you can mix up your own cleaning solution using bleach and water. Just be sure to use gloves and ventilate the area well while you’re cleaning.

3. Use a grout pen. If your grout is only a little bit discolored, you may be able to get away with using a grout pen. These pens come in a variety of colors, so you can find one that closely matches your grout’s original color. Just color in the grout lines, let it dry, and you’re done!

4. Replace the grout. If your grout is severely stained or discolored, your best bet may be to just remove the old grout and start fresh. This is a bit of a bigger project, but it’s definitely doable if you’re feeling up to it.

No matter which method you choose, getting your grout white again is definitely possible – so don’t despair if your tile starts to look a little bit dingy. With a little bit of elbow grease (and maybe a trip to the hardware store), you’ll have your grout looking new in no time!


When should grout be resealed?

Grout is often referred to as the forgotten stepchild of tile installation. It is common for people to forget about grout once the tile has been laid and the project is complete. Regularly sealing your grout is an equally essential part of the longevity of grout.

What is the recommended frequency of resealing grout?

Standard grout that has a sealer applied will need to resealed once every three to five years. Note, this entirely depends on traffic and element exposure.

Epoxy grout will not need to be resealed as frequently as regular grout that has been sealed. But a visual inspection once a year is recommended.

Traffic plays a large role in how often grout should be resealed. High-traffic areas should be assessed at least once a year.

Moisture exposure is another factor. Bathroom and kitchen tile and grout should be assessed at least once a year to ensure the protection is still holding up.

There really isn’t a concrete answer to this question and your best solution is to frequently inspect your grout for sealer failure. If the grout is dry and you can see where the sealer is missing in areas, then it’s best to have them professionally inspected.

Does the Grout Color Need to Match the Tile?

It is important to consider a few factors when choosing a grout color. In order to achieve the desired look for your project, the most important factor is the overall design. In order to achieve a seamless appearance, it is recommended that you use grout that closely matches the color of your tile. It can be beneficial to choose a grout color that is different from your tile if you wish to create a more contrasting appearance. When choosing a grout color, you should also consider a few other factors.

You should consider the type of tile you are using. Choosing a darker grout color will help you to create more definition and contrast if you are using a very light-colored tile. A lighter grout color can help brighten up the space if you are using a very dark tile. The size of your tile is another factor to consider. A darker grout color can make an area appear larger if you are using small tiles. You can make the space appear larger by choosing a lighter grout color if you are using large tiles.

After considering the overall look you desire and the factors mentioned above, you should be able to determine which grout color is most appropriate for your project.
