A Little Background

The grout is an important part of any tiled surface. Grouts have the duty of binding together tiles or even natural stones. They are used particularly in tiling floors, walls, countertops and bathrooms. They have a rough, concrete-like surface when they harden.
Grouts come in a variety of colors and are placed and used for different surfaces and materials. It roughly depends on the color of your tiles. The most common grout types are for the white tiles. Choosing an ideal grout color will depend upon the design of your surface when it comes to tiling anything such as walls or floors.
Grouts are often the catch basins of dirt, grime and germs. Unfortunately, since grouts are the in-betweens of a tiling system, they are the ones that catch all of the dirty stuff. Imagine a dirty bathroom – the first thing you will notice is the fact that the grout becomes stained and dirty. This is a sign of germs, bacteria and building up on your grout.
A lot of people agree that grouts are very hard to clean and maintain. This is because of the fact that they are the gaps between the tiles and are very hard to reach with regular brushes or cleaning materials. They require special chemicals to scrub and clean without damaging or hurting the tiles.
Grouts often have similar maintenance products as natural stones and concrete. This is because grouts have a rough surface that when unmaintained, can yield to mold, mildew and other similar stains that a natural stone or concrete surface may have when exposed to the elements a lot. The only difference is that grouts are made to be pretty much water-resistant much more than concrete and natural stones simply because they are sometimes specifically made for bathroom use.
Grouts might crack and get gaps if thoroughly exposed on outside elements or constant use. Weathering can really contribute to this matter, especially if you have tiled surfaces or sinks outside of your house. If you see a grout part snap and crack, this can indicate that the life span of your tiles is in danger. When there is nothing left to hold your tiles together, your tiles and / or natural stones can break apart.
Small cracks on grouts can take its toll on your tiles or natural stones. Do not wait for small parts of grouts to have cracks and become bigger – seal them up as early as possible to protect the life of your tiles. We all know that tiles aren’t very cheap and you will want to save your budget in the long run.
This is why you need to maintain your grout by using a grout sealer. By using a sealer for your grout, you can extend the life of your tiles or natural stones and keep them together for a long time. Sealers for grouts work much like sealers for driveways and concrete – they help in sealing up the gaps and cracks that form in your grout so that your tile surface or wall will hold together for a longer time.

How We Picked

In picking the best grout sealer, we chose carefully using the following criteria as our guideline to choosing the best:
We considered the ingredients of the grout sealer. Most grout sealers you will find are water-based and can be applied using special applicators or even small brushes. Having the right formula and contents is important for choosing the best grout sealer.
Price may play an important role in deciding for an effective grout sealer. While grout sealers are neither exactly too cheap nor too expensive, it is best that you decide within an effective price range from $5 to $40 or so.
The area that the grout sealer can cover in maximum should also be known or at least estimated. This is expressed in square feet per gallon or per quart. This also includes the thickness of your grout – some applicators have a 1/8 and 1/4 wheel at the end to apply the sealer much easier.
The texture of the grout sealer when applied and dried should be considered and should match your current grout. Always make sure that the grout sealer is of the same or similar color or compatible with your tile type or surface and the sealer should match your previous grout so it will blend in better.
Do consider the drying time as well as the curing time of the said grout sealer. Most grout sealers have a faster drying time compared to cement sealers because they are particularly used in very small spaces as compared to big road and driveway repairs. Ideal drying time is around 5 to 15 minutes.
Ingredients used for the grout sealer can be a basis for judging the best sealer for grout. We did mention above that most grout sealers are water-based but they should also have ingredients that professionally cure your broken grout. It is best to compare product per product first.
Some grouts are applicable for different surfaces. Consider a grout sealer that is highly adaptive to a variety of materials and tile types. Not everyone will be using grout sealers in sealing up grout for tiles. Some will use them on grouts between natural stone, so consider this factor as well.

Other Frequently Asked Questions

Q: How important is cleaning and maintaining your grout?
A: Cleaning and maintaining your grout whether it is for your tiles or for a natural stone system helps to maintain the look of your floor. A shiny floor tile set or a bathroom wall makes the difference not just for your family but also for guests who arrive at your home or for a public restroom or establishment. Most people agree that grout maintenance is very hard because it is a hard to reach area that can only be cleaned with a very narrow applicator such as a brush or applicator wheel for putting in the grout sealing material for it to get repaired and get the tile safe and away from mildew and mold and thus, effectively improving the lifespan of your grout and tiles.

In addition to that, most dirt and grime can be removed when grouts are maintained. Mold and mildew often put their place in between the tiles, since most tiles are nonslip in their surface so they will stick to the rough grouts instead. Since grouts are the unfortunate catching basin of dirt, they are the ones that should be maintained and cleaned so that they will not crack or have damage on them in the long run. However, some weather conditions will definitely take its toll on your grout, especially if you have tiles outside your patio garden or an outdoor sink or kitchen in which the grout may be exposed to harmful elements outside your home.
Likewise, proper maintenance of your grout keeps your household free from bacteria, mildew and mold. A dirty grout will not just take its toll on your tiles but your family as well. Imagine if your kids often hold the walls of the bathroom or lie on the floor – they might catch unwanted bacteria and virus as well as sickness causing germs that can lead to your budget being compromised as well as your family’s safety. So to be safe, make sure you clean up your grout so that mold and mildew will not stay there.

Moreover, as we said, you can save dollars in repair if you maintain the grout and keep it clean or sealed. A properly maintained grout goes a long way in terms of health and safety as well as sanitation. Public places are the most important ones to clean up, since many people are using them day by day and round the clock, most of the time. So if you are an establishment: make sure your tile grouts on your bathrooms and floor tiles are kept clean and sealed so that your customers will not complain in the future or cause accidents that might hurt your customers. This is because broken grouts can lead to broken tiles, which can lead to slipping and retiling. We all know how much hassle it will take when any establishment, such as a mall, will go under renovation just because of grout that is not kept clean and maintained properly.

Q: Any basic tips on how to seal the grout?
A: According to WikiHow , you should always wait 48 to 72 hours before sealing any grout for best results. In addition, you should make sure grout is dry before resealing. In terms of putting in the grout sealer, it is recommended that you use a roller or a small paint brush when applying. For the drying time and penetrating time, please allow 5 to 15 minutes which is the ideal time of letting the grout to soak.

After applying the grout sealer onto your tile grout or natural stone grout, you can use a dry cotton cloth in wiping away excess sealant from the tiles. Other than water-based sealers for your grout, there are also aerosol sealants you can buy but they can be a bit messy and difficult to apply and may not work as strong as common grout sealers. Last but not the least: make sure the sealer cures properly before using.
