Grout Sealing

Properly Sealing Grout Will Keep It From Becoming Dirty And Stained. Grout is an extremely porous substance which can harbor dirt, mold, mildew and bacteria.

Sealing your grout will shield it from those contaminates and keep it out of getting dirty and stained over time. You should seal your grout 72 hours following it has been installed and you need to also re-seal your grout at least once per years particularly in showers and high traffic areas like tile flooring.

Why Grout Sealing is Important

Why Grout Sealing is Vital

Though tile floors are often easier to maintain than others, they do require regular care beyond sweeping and cleaning. A lot of this has to do with grout.

Commonly, grout contains cement mixed with sand, water, and polymer additives that cures into a hardy, ceramic-like substance. Grout is often fairly porous, though, and vulnerable to liquids and soil seeping into it. This can not just stain and discolor the grout but also damage it and boost the growth of mold.

However, sealing grout soon after it heals and reapplying the sealer at least after each year can prevent discoloration and damage, as well as reducing the regular cleaning needed.

How Grout Sealing Works

Before resealing, the grout and surrounding tiles should undergo deep cleaning to eliminate any existing dirt and grime, then allowed to wash again; this is provided as a member of the grout sealing service. After this, one of two kinds of sealer is applied:

Penetrating sealer, which uses a water base to carry latex and silicone particles to the grout; these particles fill in pores and openings to prevent any other substances from penetrating. This is the ideal selection for ordinary areas of a home or business.

Solvent-based sealer, which makes a durable, waterproof barrier over the surface of the grout to block moisture. This works best on resisting water in showers and moist areas of concern; it can also color the grout, but this can be an upside if you are opting for a particular look . 

Cleaning and Reapplying Grout

Sometimes, grout is too far gone. Mold, bacteria, and mold which can be entrenched in grout long can be extremely difficult to eliminate with cleaning, and if the grout is already damaged, then cleaning is of little assistance. While regular sealing can prevent grout from reaching this stage, grout removal and re-application can also help renew tiling that has seen better days.

Grout Sealing Tips And Advice

You should only seal cement based grout.

Epoxy, urethane and other types of synthetic grouts do not need to be sealed. Sealing these types of synthetic grouts can do more harm than great for protecting them. Additionally you should not seal your grout if it has been re-colored, dyed or sealed with an epoxy based grout colorant. 

Grout colorants will place a outer coating of sealer on top of the grout that also serves to seal the grout. Sealing grout that has had a grout colorant implemented can do more harm than great for protecting the grout.

You must always reseal your grout it has been deep cleaned.

You must always reseal your grout it has been deep cleaned. Deep cleaning grout with strong alkaline and acidic cleansers can break down the sealers in grout. Grout sealers will also break down over time, so you need to seal your grout at least every 3-5 years. You always need to thoroughly clean your grout before sealing it. You do not need to seal in any dirt and contaminates causing permanent hard to remove stains in the grout.

Shower grout gets a lot of abuse so that you need to seal your shower grout at least once a year.

The wet grout in showers is an ideal place for dangerous toxic mold to live and breed. Sealing the grout will help stop water from being absorbed bi the grout. Wet shower grout is an ideal place for mold to bread and live so sealing the grout is the best method to keep mold and mildew from growing in the grout.

There are two basic types of grout sealer applicators.

The brush tipped applicator is suitable for sealing little grout joints and for sealing vertical grout joints found in showers and backsplashes. The roller wheel type applicator functions better for sealing wider grout lines on flat surfaces like tile flooring.

You need to seal your grout if it is not too hot and you do not need to seal the grout in direct sunlight.

It is essential that the sealer doesn’t dry on the tile surface as you are sealing the grout. If it is a hot summer day, try to seal the grout in the morning or evening when it is the coolest. 

You also do not need to seal grout in freezing cold temperatures. You need to read the grout sealer manufactures directions for the appropriate conditions and temperatures recommended for utilizing their grout sealer.

It is important to only use a high quality professional grade sealer.

Low quality sealers from local home improvement stores won’t provide much protection for your grout and they’ll allow your grout to readily become stained. Also these low grade sealers won’t last long and they’ll break down readily with normal everyday cleaning solutions. Stonetech Bulletproof performed one of the best sealers for protecting grout in our grout sealer review. The one quart container of grout sealer will seal approximately 200 sq/ft of grout with 12 inch tiles and 1/8 inch grout lines.

Apply a liberal amount of sealer to the grout joints and be sure that the grout is thoroughly saturated with sealer. Don’t worry if some of the sealer gets on the surface of the tiles. The excess sealer on the tile’s surface will be wiped away later . 

Work only in small sections at a time and keep the grout joints saturated with grout sealer for 5-10 minutes. If you see that the sealer is becoming consumed by the grout and starting to dry then apply more sealer to the grout to keep it thoroughly saturated using the grout sealer. If an area of sealer starts to dry on the tile surface, then add more sealer to keep which area saturated with the grout sealer.

You should first seal the vertical tile surfaces such as backsplashes and shower walls.

You should first seal the vertical tile surfaces such as backsplashes and shower walls.

Hunting to keep these vertical grout joints saturated with sealer for 5-10 minutes can be a challenge that is not always achievable. Try to get as much sealer into the vertical grout joints as possible without allowing the sealer to dry on the surface of the tiles. 

Gently applying sealants to the vertical grout lines while always wiping the excess sealer off the tile surfaces would be the best method for sealing grout on vertical tile surfaces.

After sealing the vertical tile surfaces then you can use the roller wheel applicator to seal the grout on the horizontal tile surfaces.

It’s much simpler to keep the grout saturated with sealer on the flat tile surfaces like tile countertops and tile flooring. These flat surfaces may also get dirty more quickly so it is more significant to completely seals these surfaces to protect the grout out of getting stained and filthy.

After the grout has been saturated with sealer for 5-10 minutes you then need to wash off the excess sealer in the grout and tile surfaces.

The simplest method to wash off the excess grout sealer is to simply use ordinary paper towels. Roll up about 10 sheets of paper towels and use them to wash down the tile and grout surfaces. When your sheets of paper towels make saturated with sealer then only throw them away and get a new wad of paper towels and maintain cleaning up the excess grout sealer.

Eliminate all of the sealer from the tile and grout surfaces and make sure which there are no puddles of sealer left in the grout lines.

Continue wiping the tile before all traces of the grout sealer are gone and there’s absolutely no grout sealer haze left on the tile surfaces. It is important not to leave any traces of sealer residue on the tile surfaces. Examine the tiles from various angles to ensure that there is not any sealer residues or sealer haze left on the tile surfaces.

After you are done sealing the entire area then do a final review to check for grout sealer haze or sealer residue left on the tile surfaces.

If you see a grout sealer haze on the tiles then you can apply some more sealer to the regions of sealer haze. This will reactivate the grout sealer so that the grout sealer haze can be removed. After the grout sealer haze has been reactivated you can wipe up the grout sealer haze with paper towels.

You should let the sealer dry for around 3 hours before walking on the tile floor or using any of the tile surfaces.

Also try to prevent spilling any liquids or getting any dirt or contaminates on the grout lines for a full 24 hours after sealing them. You should see the grout lines to lighten up and return for their original color as the grout sealer dries in the grout lines.

The grout locking your flooring tiles into place and providing everything a finished look is not usually at the front of your mind; the tiles are what capture people’s eyes normally.

That changes when grout stains, cracks, and crumbles, detracting from the area’s look and allowing tiles fall loose. Make sure that your flooring remains stable, attractive, and easy to clean with regular grout sealing services from Sally Steamer in Philadelphia, PA.

Sealer Choice Gold:

Why should you seal your grout? Cement grout is porous and will absorb any liquid that gets on it which could include soap scum, oils, juices, or just dirty water. Then it will stain, grow mold, and even start to stink. Nobody likes smelly grout. By sealing the grout you fill the pores of the grout so that other stuff can’t get in and stain it. Basically, sealing your grout keeps it looking new for longer.

However, not all grout needs to be sealed. If you have epoxy grout, you should not seal it because it won’t accept a sealer anyway. How can you tell if you have epoxy grout? Easy, does it look and/or feel like plastic? If so, then it is epoxy grout.

Next, I talk about how which sealers are best to use and why. Basically, any high quality penetrating sealer with flourochemicals is best. That way there are different sized particles that can fill in the gaps on the grout.

Finally, I’ll share three ways to apply the grout sealer to the grout. I mention a method to apply sealer to floor tile grout, shower tile, and even natural stone tile. Just make sure to clean your grout well before sealing, otherwise you will seal in stains!

How much grout sealer do you need? Not much, I would recommend buying the smallest amount you can unless you are planning to seal a large amount of floor tile. You can usually seal an entire shower at least 3 times with just one pint of sealer.

And finally, I give you some tips for sealing your grout like how to remove grout sealer that has dried.
