Is There A Waterproof Grout Sealer?

Filling the spaces in between different kinds of tiles with grout, which is a mixture of cement, sand, and water, frequently with colour added, is a purpose that grout fulfils. One thing, however, is unavoidable: ultimately, discoloration, mildew growth, and damage will occur as a result of splashes of water or other liquids, regardless of whether the tiles in question are on your floor, kitchen countertops, or bathtub surround. There is, however, a solution, and it is called grout sealer. You can prevent moisture from getting into the grout by applying it once a year (or even once every six months if the tile is frequently wet), which will keep it looking its best for a longer period of time.

When the appropriate supplies are utilised, applying grout sealer is a straightforward, albeit time-consuming process that is well within the capabilities of even the most novice do-it-yourselfer and can generally be completed in just a few hours. We have made it even simpler by conducting research on the numerous types of grout sealer that are currently on the market — some products protect only the grout, while others help protect the stone or tile that is surrounding the grout as well — and then narrowing the options down to those that perform the best in a variety of applications throughout the house.

When tiling, grout sealer can make a huge difference because it protects the grout from absorbing stains, water, and bacteria; it extends the grout's lifespan; and it makes the grout seem like new for much longer.

When selecting a grout sealer, there are a few factors that should be taken into consideration, including its resistance to water, the method by which it is applied, and its longevity. Because we have covered everything in this comprehensive guide, you won't need to do as much research on your own, and it will be much simpler for you to determine which grout sealer is the most effective.

There are several kinds of grout sealers on the market, and we're going to go through all of the different kinds and brands available so that you know precisely what to get. We will point you in the direction of the most effective grout sealers for the job, whether you need them for your shower surround or your kitchen floor.

Because grout sealer is such an essential part of the process of installing tile on floors, walls, and showers, defining what it is and explaining why it is important in your house or place of business is not a tough chore at all. Grout sealers are utilised for a variety of reasons, the most important of which being the fact that they aid in preventing moisture from penetrating the grout spaces that are located beneath your tiles.

When a grout sealer is put initially, it helps keep any liquids and moisture away from the tiles for the longest time possible, because water can get in the spaces between tiles and make it so they don't stay connected for very long.

In this piece, we will discuss methods for sealing and protecting the grout that is located between your tiles against water damage. Grout is a liquid that has the consistency of cement and is used to fill the spaces between tiles. People frequently have the misconception that grout is waterproof. On the other hand, it is frequently fairly rough and porous. It is not difficult for liquids such as water, oil, or other liquids to pass through it.

This indicates that your grout, if it is not sealed, has the potential to become discoloured, develop mould, and start to smell if it is not properly maintained and cared for. It is a good idea to seal and waterproof your grout if you want to prevent it from becoming impregnated and ensure that it will ultimately survive for a longer period of time. It is only necessary to complete this step once if you use a high-quality sealant.

Various Grout Sealer Varieties

The grout sealer, pretty similar to every other item available, does not come in a single package by itself. It's taken apart and reimagined as several types of sealers so it can help with a wide range of chores around the house or office.

The most prevalent kinds of grout sealers, such as spray, penetrating, membrane sealers, and applicator, are discussed in greater detail in the following paragraphs.

In addition to these four varieties of grout sealers, we place an emphasis on the two most important varieties of grout sealers, which are known as oleophobic and hydrophobic sealers respectively. These fall under the category of penetrating sealers, which also go by the name of the impregnator model and are most commonly found in showers.

Grout Sealer Spray

The spray grout sealer is the first form of grout sealer that will be covered in this article. This is a fairly widespread type of sealer, and a large number of skilled workers all around the world use it. When using a spray-on grout sealer, care must be taken to avoid oversaturating the grout with the sealant.

In the event that the liquid gets spilt on tiles following the application of the spray-on sealer, it is important to remember that the tiles will need to be cleaned.

The grout sealant spray is widely used in the industry since it speeds up the application process. The main disadvantage, according to the opinions of several experts, is that despite the fact that it saves you time, the time that you would have saved ends up being wasted to clean the messes that it creates.

Sealant For Penetrated Grout Joints

The second variety of grout sealer available is likewise a well-liked option. This is the grout sealant that penetrates the grout (impregnated grout sealer is a term used to describe a type of grout sealer). As its name suggests, a penetrating grout sealer works by slowly soaking into the grout. In addition, it is administered in a method that allows it to seep into the grout and change the grout's chemical makeup.

You may notice a difference in the appearance of your grout after using a penetrating grout sealer, since these products tend to come in a dark colour.

The impregnated type of grout sealer, in contrast to the spray-on variety, protects against discoloration. The following are the two varieties of this sealer:

An Oil-Resistant Adhesive

This sealant is multi-component, and as a whole it provides oil and water resistance. Once the product has been sprayed, it will prevent water, oil, lard, and even frying fat from penetrating your grout.

Water-Resistant Gaskets

Hydrophobic sealants are highly effective at preventing the passage of water and other water-based substances. They help keep your grout free of tea, coffee and other stains as you clean it.

Grout Sealant Applicator

When compared to the spray-on variant, this grout sealing agent requires far less manual labour to apply. To assist you in sealing the grout, all you need is an applicator or a brush when using this particular sealer.

A few manufacturers construct their sealer products with rollers specifically for the purpose of making the application as simple and uncomplicated as it can possibly be.

Additionally, the brushes, roller and applicators that are included in the packing help to make the work easier while simultaneously cutting the amount of time it takes. The applicator grout sealer most commonly comes in a white colour; hence, using white applicators is the recommended method for cleaning tiles.

Grout Membrane Sealant

The membrane grout sealer is the greatest option for people who live in damp situations or who have excessive humidity in their homes. They were crafted and designed for two distinct but interconnected goals: 

1. To incorporate a coarse pigment into the grout.
2. To colour the grout and give it a luxurious look.

There is a specific way to add colour to your tiles that will hide any flaws without making them look out of place. The membrane grout sealer, however, is not advised for use in damp environments like toilets because it does not dry quickly and easily under these conditions.

Silicone Sealer

This is utilised on the margins of bathrooms and toilets in most cases, but it is applicable both inside and outside of buildings. Because it is a flexible material, it may be applied in a quick and simple manner.

Silicone sealants, on the other hand, offer protection against water and only water. The molecules of silicone sealants are all the same size, and the large molecules can only fill up a certain kind of area in the grout if there has been a spill of something like juice, grease, wine, or another beverage. It is possible for these kinds of liquids to finally break through the silicone.

To the best of our knowledge, silicone caulk should not be utilised anyplace other than around the perimeter of a shower (even then, we would recommend a water-based sealer).

Water-Based Sealer

Fluorochemical sealers that are water-based are by far the superior option. They are typically more expensive, but it gets the job done in a much more effective manner. The surface of the grout is made hydrophobic as a result of this, which means that water or any other liquid cannot penetrate it and that it may be readily cleaned off.

In addition to that, this permits any water vapour to move through the grout from underneath, making it possible for the grout to breathe. Any moisture that was found beneath the tile has the potential to evaporate over time.
