Types of Grout


There are various types of grout, as discussed below:

Sanded grout

It has large sand particles and is ideal for wide grout joints. The sand offers additional bonding power, preventing cracking. You should use this product when the grout joint is 1/8-inch or more. 

Sanded grout is suitable for ceilings, walls, and floors. It is less expensive and comes with a variety of colors for you to choose from. Most prefer it due to its aesthetic value. However, it is essential to note that the unit can scratch the tiles; hence be careful when using it on premium tiles. 

Unsanded grout

The product does not have any sand, and it is ideal for small grout lines and highly polished tiles. It has a fine texture since it is cement-based, making it easier to use it on vertical surfaces. 

Unsanded grout has no silica aggregates, allowing it to be the best choice for scratchable and fragile surfaces. Therefore, it is perfect when used with marble, ceramic, metal, glass, and natural stone tiles. 

The unit is a bit expensive compared to sanded grout and has no many colors to choose from. It can crack when you use it on large seams. 

Epoxy grout

This product is a bit different from other types of grout. It contains silica fillers, resins, hardener, and pigments. The unit is less porous and a perfect choice in the kitchen or areas with greases and acids. It withstands water and prevents mold and bacteria formation. 

The product dries very fast after being applied and comes in the form of sanded and unsanded grouts. It is more expensive compared to other types of grouts. This type of grout does not require sealing. It is hygienic, and cleaning your bathroom is easier and fast. 

Tips for choosing the best grout for your shower

Everyone wants sparkling walls and floors. For you to achieve this, there are some tips you need to know that will help you select the best grout for your shower. Here are some of the factors you need to consider.

1. Type of grout

Grout falls under two main categories: cementitious and synthetic. Synthetic grout is the most ideal for areas with much water, such as bathrooms and kitchens. It perfectly seals and prevents your walls and floors from unwanted water, mold, and bacteria. The unit also helps in appearance preservation, allowing it to last for an extended period. 

On the other hand, cementitious grout is ideal for areas where water is not a problem.

2. Grout color

Everyone has his/her preferred color, but despite all, what you need is a color that will make your walls and floors look extremely beautiful. Selecting the color of the grout solely depends on the tiles’ color you intend to use. Here are some of the tricks you need to use to choose the correct grout color:

If the tiles you have installed are white, it is advisable not to use white grout. This is because they will change the color overtime despite looking great at the beginning. Also, they need regular maintenance and cleaning for you to maintain their look. Therefore, when your tiles are white, it is recommended you use a light gray grout. This will give you a cohesive appearance and maintain its color for a long period. 

In case your tiles comprise various patterns, you will have a wide variety of colors to choose from. You can select one color from the tile and use it to match your grout color. 

It is essential to note that darker grouts are perfect for floor tiles, while light-colored grouts are suitable for wall tiles. They show all stains, dirt, and any tear and wear. Remember, the grout color you select will have a significant impact as far as your house look is concerned.

3. Grout lines

Grout lines are another vital factor to consider when choosing the grout to use. If the line is 1/8-inch and over, sanded grout is the most recommended. It will help to fill the big gaps and make them harder. 

For grout lines that are less than 1/8-inch, it is advisable to use unsanded grout. This is because its binding power is a bit less, and it courses cracks when used on broad grout lines.

4. Mold resistance

It is good to know that an excellent grout for your bathroom should protect from mildew and mold formation. This is because your bathroom is a warm and damp place, allowing the mold to form quickly. You need to find a product that will ensure it prevents this formation. This is easy as you will search for grout that is meant for the bathroom.

5. Waterproof

Almost all grouts for the shower are waterproof. However, you need to be more careful so that you don’t make mistakes. Water-resistant grouts are not the same as waterproof grouts. The best products for the bathroom are waterproof epoxy grouts. It is fully waterproof after being cured, high moisture resistance, and maintains a cohesive look for an extended period.

6. Maintenance

Although many people do not put this factor into consideration, it is very crucial. Shower grouts are prone to water and soap; hence need regular cleaning. To clean your bathroom, you will need to use some cleaning products. This might damage the grout when used for an extended period. 

Before purchasing any product, ensure you read the fine print to see how to clean it and if it’s convenient and safe for you. Some grouts require some special cleaning products, which may be costly.

7. Curing time

Grouts take independent time to cure. This depends on the manufacturer. Some take a minimum of four hours to cure fully, while others take as long as 12 hours. If you have limited time for modeling your bathroom, you can choose the grout that takes a short time to cure. To know the curing time of the grout, check the fine product print.

Question: Is the sandpaper ideal for removing excess grout?

Answer: NO, sandpaper cannot be used to get rid of excess grout. It may remove more grout and get the sealant that seals the tile out. You may end up starting from scratch. For you to remove excess grout, it is advisable to use a soft sponge that will not destroy the tile. 

Question: Can I apply new grout on top of the old one? 

Answer: Although many people are used to doing this, this is not the right way. You should first remove the old grout and then apply the new grout even if there is a high possibility that the new grout will not stick on top of the old grout. This might lead to peeling off in a few days to come. 

Question: What is the best grout for use near the shower?

Answer: The best grout to use near the shower is epoxy grout. It is water-resistant, and you don’t need to seal it frequently since it is a natural sealant. 

Question: How long should I wait before I apply the grout?

Answer: If you are regrouting the gaps between your tiles, then you can start as soon as you remove the old grout. In case you have changed your tiles, the appropriate waiting time is at least 24 hours. Waiting for this long will allow the tinsel to get dry, such that no humidity is trapped underneath. 

Question: Is it okay to clean the dirty grout instead of removing it?

Answer: Yes, it’s quiet in order. This is because it is cost-effective to clean the dirty grout instead of re-grouting. You only need to be a bit careful with the cleaning products you are using so that you do not damage the grout.
