Is it safe to seal grout?

Grout sealers are chemicals that can be harmful. However, their harm can be kept safely at bay by choosing the right Grout sealers. Choosing the right one with minimum or no harm, even at all, you will have to look for the company that is selling safe Grout sealers for shower.

To buy a sealant, you will first have to do some research on the company which is known to take health precautions before manufacturing their products. Not alone will thus reduce the adverse effects of the chemical, but it may still tolerate you to eliminate them.

Is it safe to use Grout Sealer

Once you have bought the best rated grout sealer for shower from a top-quality company, you need to take only a few precautions. This includes avoiding skin contact with the chemical and keeping it away from heat. Ventilating the area will further reduce its harmful effects. If you take these precautions, the grout sealer will be perfectly safe for you to use.

Factors to Consider While Buying Grout Sealer

Certain factors should be kept in mind while buying the grout sealant. A grout sealer ensures how safely your tiles are secured in place, their general look, and their lasting duration. It is advised that you refer to a Grout sealing buying guide that can tell you which products are worth spending your money on.

Solvent Based

Since most people would prefer tiles in their shower, a grout sealer for the shower should be solvent based. A solvent based sealer consists of molecules smaller than the molecules of water. This helps keep the water from penetrating the sealer and damaging the base of the tiles. This extends the life of the tiles and saves your bathroom from permanent damage that may be caused by water seepage.

Where You Wish To Install The Tiles

This is also a very important factor in choosing the right Grout Sealer. If you wish to install it in a kitchen, where oil spillage may happen, a stain-resistant sealer is recommended. This helps keep the kitchen clean as it prevents the tiles from staining. It is also very easy to clean. A water-based solution for the sealer will make it even better because it will leave no smell. The water-based solution evaporated once the tiles have dried. This allows you to have a kitchen or home that looks and smells natural.

Sealer With Volatile Solvent

A grout sealer with a smell will not only leave your house stinking but also have adverse effects on those living in that house. Children and pet will be less resistant to the effects of this smell and therefore for health reasons, you must choose a Grout sealer that will have a volatile solvent in it. This helps the solvent evaporate and once that is done, the environment of the house will be safe for all.

Best Grout Sealer for Shower


The sealers durability is without a doubt, the most important factor. If a Grout sealer is not durable, you are just wasting your money because you will need to repair your entire kitchen or shower floor again after a while. When buying a seller, you can look at how long the product is guaranteed to last. A minimum of five-year guarantee means you are safe and the tiles will not need frequent application.

Material Matching

You need to pick a Grout sealer that matches the nature of the material you are going to seal. Flooring can be of various types and different types of flooring will require different types of Grout sealers. Marble, tile and polished granite will require a solvent-based sealer. While materials like brick, clay, and slate will require water-based sealers. This is due to the varied chemical structure of the Grout sealer and the flooring material.


The appearance of your flooring is a significant factor. After all, who would want to spend large sums of money buying high-quality material for their flooring but in the end it looks bad because of bad sealer. You need to choose the sealer that will enhance the looks and durability of the flooring material. This includes prevention from stains. Stains can be of both water and oil. Both can be stubborn stains that simply won’t be cleaned. A good quality Grout sealer coat can help prevent these stains and give the flooring a proper ending.

An AFM soft coat

It will enhance the abilities of a Grout Sealer. This coat is what ensures the long-lasting look of tiles. Many tiles will start to fade after a while, leaving the floor look like old and wary. An AFM safe court will prevent this from happening to the tiles. Once this coat is applied to the tiles, the tiles will be looking like new even after years. This saves you a lot of money on renovation.

How to apply the grout sealer properly on the shower floor?

Application of grout sealers varies. This depends on the type of Grout sealer you choose and the size of the tile you are using it on. However, make sure you are using an applicator brush, wearing protective clothing and avoid skin contact with the sealer. A brush or roller will make the job easier while wearing protective clothing will protect your skin from the harmful chemicals in the sealer. You can use brushes, rollers or spray to apply the sealer.

Use Brush Tip:

When using a brush, you will have to apply the sealer onto the grout. You can easily do it with the brush tip. In doing so, you will have to be careful so you don’t get any sealer on the tile itself. Using a brush can be hard. We suggest brushes for experts only. It can be hard for beginners.

Using Roller:

The roller is the second-best option to use grout sealer in the bathroom. Using a roller is the fastest and easiest way to apply the sealer. All you have to do is apply is throughout the tile line. It will not require reapplication which will save you a tremendous amount of work. Although the roller is not very accurate, it helps the sealer stay close to the seam line. It also helps keeps the sealer away from the tile surface.

Grout Sealer Spray:

Grout sealer spray is another way that you can apply your grout sealer. This is the easiest thing you can do to apply the sealer. It’s fast and uses less energy. It soaks the sealer into a porous surface but does not stick to the glazed surface of a tile.

This means that if you get some sealer on the surface of the tiles, it will eventually come off. The problem with this applicator is that even though you will have saved yourself time and energy on applying the grout sealant for shower, you will need to spend plenty of time and energy to clean off the excess spray on the tile surface.

Q: After how long should I reseal the Grout?

A: Different manufacturers have different dates that they recommend for their products. However, according to the Tile Council of North America, it is important to reseal your grout at least biennially.
