If you want to find the best grout sealer for the money, here are some important factors to look for.
Both the surface as well as the surface area is important when purchasing the grout sealer. If you have to apply sealer to a larger surface area, then it is recommended to go with a gallon size grout sealer.
The manufacturer should be able to tell how much surface their product is able to cover. A typical grout sealer should be able to cover anywhere from 1000 square feet to 4000 square feet per gallon.
Basically, there are 2 types of grout sealer on the market. Penetrating and non-penetrating.
Penetrating Grout Sealer: As its name suggests, the penetrating grout sealer penetrates deep into pores of the grout line as it mixes with the grout.
This type of grout sealer is very effective in combating mold and will help keep your tiles look clean and brand-new for years. Moreover, the lifetime of the penetrating grout sealer is estimated to be anywhere from 10 years to 15 years.
Non-penetrating Grout Sealer: On the other hand, the non-penetrating grout sealer works pretty much the same way as paint. It is a layer of transparent sealer that solidifies on top of the existing grout in the grout line.
One of the best advantages of the non-penetrating sealer is its long lifetime, much longer than the penetrating grout sealer. Indeed, this type of grout sealer is extremely durable and long-lasting.
However, the major caveat of the non-penetrating ground sealer is that it is very hard to remove.
In addition to being penetrating and non-penetrating, the grout sealer is also either oil resistant or water resistant.
It is quite rare to get the grout sealer that is both oil and water resistant at the same time. Your choice between oil and water resistance will depend on your application.
For showers, the waters resistant ground sealer is the preferred type because you need your grout line to be fully water resistant.
On the other hand, if you’re looking for a general-purpose grout sealer then you can safely go with an oil-based ground sealer.
One of the most important aspects of the grout sealer is effectiveness. Indeed, you want your ground sealer to perform its task of protecting the grout line as well as preventing the formation of mildew and mold.
Not all grout sealers are created equal and some are superior to others. In our grout sealer for shower review above, we have handpicked a few highly effective sealers that are worth the investment.
Moreover, you need your grout sealer to be long-lasting and durable. In most cases, a grout sealer should last you at least 3 years if you choose to go with a penetrating ground sealer.
If you need a longer lasting sealer, that it is recommended to go with a non-penetrating ground sealer because this type of sealer has been proven to last longer than 15 years.
As a matter of fact, sealers like the Miracles Sealants 511 Impregnator are champions of longevity because this sealer will provide your grout line no less than 20 years of protection.
Some grout sealers have a color added to them for aesthetic look. If you want to change the color of your grout line, this is an excellent type of grout sealer to buy.
On the other hand, if your grout is already colored and you just want to make the colors pop, you can go with a transparent grout sealer that will give the grout line a wet and attractive look.
For your safety, as well as the safety of others, especially small children, it is important to ensure that the grout sealer is food safe.
A food safe grout sealer will also not cause irritation to the skin, especially when it comes in contact with water.
How to Apply a Grout Sealer for Shower
Applying the grout sealer is extremely easy. Here is a stepwise manner on how to proceed with the job.
First and foremost, you need to ensure that the tiles, as well as the grout lines, are clean. This would allow for a better adhesion and a faster curing time of the grout sealer.
You can clean the tiles with a wet sponge or by gently brushing with a brush and water. Additionally, go through each grout line with a wet cloth so that it is free of dust and debris.
While you do so, make sure that the room is well ventilated so that the grout sealer can cure faster and more naturally.
If you are using a grout applicator with a bottle and roller top, then fill up the bottle with the grout sealer.
Afterward, roll the applicator wheels on the grout line in such a way that it fills each grout line with the sealer. Keep doing so until you have filled all the grout lines.
Once you have applied the grout sealer, your ceramic tiles should be dirty and covered with the haze which is a typical effect of the grout sealer that has started to evaporate and cure.
You will need to clean it as quickly as possible so as to prevent the grout sealer from drying on the tile which will then be very difficult to remove.
Again, you can use a wet sponge or a wet cloth to clean the tiles. Avoid using too much water in this step as it may erode the grout sealer from the grout line.
Allow the grout sealer to cure. The sealer manufacturer should mention the amount of time it takes for their sealer to cure.
Once it has cured, it should be as solid as cement. Use a dry paper towel to buff your ceramic tile surface again and remove any haze that remains.
Not all grout sealers are made equally — some do better at fast-curing, while others are longer-lasting. Certain people may prefer to have a non-toxic version that is eco-friendlier. In this buyer’s guide, we will discuss the different options, what makes a good grout sealer, and how you can choose the one that will best fit your needs and your budget.
First, know what type of surface you are dealing with. You need to know if your grout is sanded or unsanded.
Cement-based sanded grout: This type is porous and is made from a mixture of water, cement, and sand. It is more susceptible to water and grease damage and can be negatively affected by dirt and mold. It is the most common grout and the least expensive.
Epoxy-based unsanded grout: This grout is strong and durable, made from epoxy resins that are combined with filler powders. It is also more expensive and has a plastic appearance. It is non-porous, cleans easily, and is almost stain proof. These won’t need to be sealed.
This is a surface coat that will protect your floors and backsplashes from water exposure, grease, and dirt. These are best for areas that aren’t exposed to high amounts of water, such as the kitchen. It will need to be applied every one to two years and works best on grout within natural stone and unglazed tiles.
These are long-term sealers that seep into the grout, providing protection for at least three to five years. They work best for natural stone, ceramic, and porcelain, since it leaves your tile natural looking. They are the ideal choice for bathrooms, showers, and tubs.
Amount: Make sure you buy enough product to cover the area you want to seal. Determine the square footage and purchase enough sealer to coat it all. Most sealers will give you general guidelines as to how much it will cover. Keep in mind that you will want to apply at least two coats of sealer.
Application: The best way to apply a sealer to grout is with a sponge or a brush for precision work. Certain products will come in a spray bottle, which can be applied over your tile surfaces as well. You will spend less time cleaning your tile if you use a sponge or brush. On the other hand, the spray is easy to apply in one shot, and then you wipe off the residue as you go.
Toxicity: Solvent-based sealers will contain the most chemicals and it is recommended to wear gloves and a safety mask when using this type of sealer. Water-based sealers are a safer alternative, having lower VOC levels. Products that say non-toxic or formaldehyde-free have the least harmful side effects.
Cost: The average cost can range from $0.80 to over $1.50 per square foot, but there are handy online cost calculators available that will help with determining the price. Think of it as an investment and a timesaver. It will help your grout stay beautiful and save you from having to clean it so often.
Wait at least 48-72 hours to seal new grout, to allow it to cure and dry. It is best to seal your grout within the first two to three weeks of installation. If you have recently used the shower or tub, allow the grout 12 to 24 hours of dry time.
For existing grout, clean well before applying the sealer. There are special grout cleaning solutions, but you will want to scrub the grout to remove all dirt and mold. Then wait until the grout has dried before applying the sealer.
You can mask off any surfaces you do not want the sealer to touch, such as any wooden or metal finishes.
Provide adequate ventilation in the room where you are sealing: Open the windows and turn on the fans. This will remove the odor, as well as help the sealer dry faster.
Spending extra time and money on a high-quality, long-lasting sealer will save you in the long run. It will also protect your tile from stains and moisture, allowing it to retain its natural beauty for many years.
Our reviews list highlighted 10 best grout sealers, with the top choice being the Aqua-X since it is easy to apply, has a low odor, and offers great coverage. For the best value, the Miracle Sealant is an impregnator that will provide durable protection for many years, at an affordable price.
