Dupont Grout Sealer Review 

 December 16, 2020

By  Dale Keese

When grout is used in visible areas of your home such as kitchen or shower tiles, you want to make sure they look great. Homeowners and contractors rely on grout sealers to prevent discoloration or damage in the long run. Just one spill from wine can stain grout, causing you hours of scrubbing and cleaning up. 

Grout sealers also help keep mold and mildew away. They’re not only unsightly, but exposure to mold and mildew can be harmful to your health. Skin and throat irritations, wheezing, coughing, stuffiness, and nausea are just some of the health problems caused by mold and mildew.

Dupont Grout Sealer

Many people have varying opinions on the importance of using a grout sealer. However, trust the professionals such as contractors to recommend using grout because it’s necessary. It’s best used after tiles have been installed. Grout looks sponge-like and grainy after you’ve finished your tiles, and that’s because it’s porous in nature. 

Since grout is porous, it will absorb liquids and even oil and dust. But it doesn’t have to: grout sealers solve that problem for you. 

The Dupont Grout Sealer is a product tried, tested, and trusted by homeowners and contractors alike. An incredibly efficient formula prevents discolorations and damage, saving you hours in time that you could have spent doing other things instead of unnecessarily cleaning up your grout. It also effectively prevents mold and mildew so that you can have peace of mind that you and your family aren’t being exposed to these nasty organisms in your very own home.

Caring for your porcelain and ceramic tiles gets a whole lot easier with the Dupont Grout Sealer. Unlike other grout sealers, its water-based formula features a large molecular structure which is ideal for porcelain and ceramic tile both inside and outside your home. 

Should anything spill onto your grout after applying, it will simply bead up on the surface allowing you to easily wipe it off before they get a chance to penetrate the grout. 

There are other types of grout sealers in the market, such as solvent or oil-based types, as well as membrane-forming grout sealers. But if you have valuable porcelain and ceramic tiles, there’s no doubt that the Dupont Grout Sealer water-based formula is the proven solution.  

The Dupont Grout Sealer has a deep sealing formulation which enhances its longevity. You don’t even need to use a lot; just one quart already covers up to 250 linear feet of grout! It will last for as long as a year when applied outdoors but will withstand up to three years of use indoors. This means that your grout is protected from water, oil, and dirt stains for a very long time. Imagine just how much cleaning you’d have to do if you didn’t seal your grout?

Easy Application

Using the Dupont Grout Sealer is so fool-proof that even first-timers can easily apply it. Think of it as a fun weekend home improvement project and one that will protect your investment in the long run.

New grout installations should wait 72 hours before applying the sealer. Once it’s ready, use a roller or a small paintbrush to apply Dupont Grout Sealer. Allow it to sit for 10-15 minutes, then liberally apply a second coat, which should sit around to dry for 10 minutes. 

Use a mop or dry cloth to soak up the remaining sealer from your tiles around the grout. If you notice any residue, simply dampen a cloth with Dupont Grout Sealer then use nylon pads to remove the residue. Wipe over the surface one last time with a white absorbent towel.

Lastly, allow the grout to cure for at least 24-48 hours before touching or walking on the grout. If you need to walk over the area right away, red rosin paper works best for temporarily covering it up. 

Once Dupont Grout Sealer has dried up, cleaning is best done using a solution that is pH-neutral.


The Dupont Grout Sealer has a reputation for being the most effective sealer in the market for its price. All you need is a quart, which is already enough to cover as much as 250 linear feet. 

If you outsource your cleaning, this product will save you money in labor costs. If you don’t, now you know you never have to break the bank just to make sure that your grout is protected from oil, water, and dirt-based stains as well as mold, mildew, and discoloration.
