PentaUSA Tile Grout Repair Kit - Black Grout Filler, Triple Protection, Fast Drying Formula Restores and Renews Grout Lines (Black, 8.8oz / 250gr)

This stuff is amazing. It’s easy to apply, I just used my gloves hands opposed to the tool included. Our old house is just that- old and worn. Our tile was crusty, stained and nothing helped. Our before photo is after calling in a professional steam cleaning service and it was still so ugly and dirty looking. After using this product our floors look so much better!

This product has unique properties that make it the best option for some situations. An example: I had tiled a small backsplash area behind my range with gloss black tile. I wanted to use a truly black grout. If you read reviews of black grouts, you will find many complaints to the effect that the color of the grout is not really black, but is more of a charcoal gray. Manufacturer's responses to these complaints are typically that black is the most difficult color of grout to achieve in practice, because the process of washing the grout off the tile tends to remove pigment from the grout.I don't like the process of grouting anyway, and this business of it being difficult to maintain a true black color had me looking for alternatives. I also very much wanted to avoid buying a 10 or 25 pound bag of grout for my small job.This product is recommended for repair, not for initial grouting. However, I decided to try it for my project.Positive Unique properties: The product comes out of the tube like a thin caulk, but it cures (after a few hours) to a hard, durable surface like regular grout. It is a fine-grained material suitable for use in narrow grout lines. Before it cures, it is easy to clean up with plain water. No odor. Note that the cap on the tube does not seal the tube -- air will fill the tube after you cap it and release it. However, the remaining grout remained fully usable for weeks after I initially opened the tube. All good things, and really impressive.Negative properties: As it comes out of the tube I found that it was not easy to get it to go where I wanted it. It is not as easy to manage as are most regular caulks in that regard, though it has a similar consistency. Also, once you have initially filled a gap with it, it often opens up "pinholes" in the center of that gap. These are both properties that can respond to correct application techniques, but you have to figure out these techniques yourself, by trial and error.After an initial test application, I moved on to my real grouting job. By the end of the job I had a much better control of the process than when I started, but I still wasn't completely happy with the way the grout went down. It took me a lot longer to use this product than regular grout would have. However, the job turned out reasonably well, and overall I am happy. I'm really glad not to have a huge amount of grout left over!One other note: the tube that the product comes in is made of tough plastic and is difficult to squeeze for someone with arthritic hands like myself. As shown in the included photo, I modified a Gill Mechanical "Tube-Wringer" with screws and wingnuts so that I could apply a major squeeze to the tube without using my hands. When adjusted correctly, I could then dispense the grout using only a small additional squeeze from my hands.

You need a super steady hand or a lot of patience. But it worked for us while getting our house ready to sell. Just buy some scrigit tools to scrap off the sides.if you’re messy.

I was so scared at first and couldn’t make up my mind of I wanted to try this or the pen…. First pic is what I had before, then I made a hot mess applying it. I would use your finger not the tool in my opinion. The third pic is where I’m in the process of cleaning up my mess. I let it sit for about 3 in a half hours and took my mop to it. The black came off my tile as you can see but left a few spots, again I’m not done cleaning it. I will have to get down and finish cleaning it by hand in some spots. Totally, highly recommend this!! I’m so in love and so easy and easy clean up! I’ve never used a grout pen and probably won’t ever now that I’ve used this! Hopefully it’ll last a long time.

I can’t understand how this product got so many positive reviews. Don't waste your time and money. This product doesn’t work at all although like many others looking for perfect tile grout products, you will have high hope for it. I used this where the shower floor meets the wall and to fill the gap between old tiles. To obtain the best results, allowed a longer dry time (24 hrs) than directed. However, the results were very disappointing; this product didn't exceed my expectations. Like many other tile grout products, it all started to melt away after having just two showers. The adherence was very poor. Above all, it seemed hard to say that this product is waterproof, but water-penetrable; it started to become slightly mushy soon after it contacted with water. It was not easy to use, too. It did not come out of the tube easily. When it did, it was messy. It tends to get all over the walls and tiles. I think, it would be better to use this where there is no direct water contact, NOT for the shower floor. Don't be misled by positive feedback; it's neither waterproof nor for the shower floor!!!

I needed a more flexible grout to repair joint between tile and wood floor. Previous repairs with grout did not seem to last. Pental grout was easy to grout and level. color match was excellent. Time will tell if it lasting although it is flexible and should allow for traffic.

Much easier than trying to mix your own grout. So easy and convenient. The applicator was very useful.

Decided to redo my bathroom tile grout after a red nail polish incident. First I tried a white grout pen. One pen did not finish it, and it was going to need a second coat, probably 3 pens total. I got this instead of buying more pens. Way way better. Better results, cheaper, and more time efficient. I didn’t need to put any tape down. It wiped off the tile with a dry rag just fine. The spatula thing wasnt very helpful for me because my floor is uneven and the small tiles made more corners. I used my finger to spread it through the grout. Would recommend over grout pens for sure!!

Not as easy as I hoped but good price and outcome. I ended up handpainting it on. Lots of work with the finish. Looks great.

This product is truly exceptional. To start with, the grout color is incredibly rich and a true black, providing a stylish and modern touch to both my bathroom and kitchen. Its smooth consistency, reminiscent of toothpaste, made it incredibly easy to apply. Unlike other grouts, there was no need for mixing, saving me precious time and effort. It was as simple as child's play to apply. The product I purchased proved to be highly useful, allowing me to achieve precise and even grout lines. It dried surprisingly fast, so be prepared to promptly clean up any excess. Although a few spots required some additional touch-ups, it was a minor inconvenience in the grand scheme of things.

My kitchen looks brand new again.

Absolutely amazing! Much better than the paint. If you put it on the existing grout, sand it a little bit first, to remove grease and dirt. I also noticed that applying it with a finger was way easier and quicker; I used the spatula (or whatever its name is) in the corners. If you do it properly, it’s durable. Highly recommended.
