We have an original bathroom floor (built 1950s) with 1 tile. We have not been able to keep the grout clean, so I thought I would give the grout pen a try. 1. It works, as you can see in the pictures. 2. Because of the amount of grout, I had to buy seven pens to get to the second picture. I bought three more to finish it off which I have yet to do. 3. This is time-consuming work. Because the grout was wider than the pen, I had to go over each grout line several times. 4. The pen is frustrating. It starts off working well, then it needs priming which smashes the tip so you no longer have a fine line. This worked for me because my grout was wider than the pen tip, but it would be hard to keep a fine line otherwise. I finally started priming with my fingers to try to keep the pointed tip, but that only worked for a while. I even flipped the pen tip to try to keep the fine line, but eventually both ends were smashed. 5. It was really hard to know if there was more grout in the pen, so I may have thrown away pens that still had grout, but it wasnt coming out, so I tossed the pen. I see this as a temporary solution, but I am thrilled with how my floor looks. I am not sure how long the grout will hold up, but this is good for now.

In all seriousness, some reviews scared me because they acted like they used this pen on one strip of grout & it ran out. That is NOT true at all!!!! I am using these on my whole kitchen floor & they work so well and do not run out quickly. I think people pushed too hard at first and/or they didn’t try that hard to use it correctly, lol. They’re awesome & totally worth it!

Basically, this stuff paints your grout. It does a fantastic job for about 15 minutes - then the tip becomes frayed and the paint runs out. Would give it 5 stars if it lasted longer. See my before and after photos of my kitchen tile counter. It doesnt clean up all the dirt in the cracks but does cover most of the uglies.

Changed my old (left) tile back to white (right) in a weekend. Follow directions and don’t push to hard. Tip is also reversible. Great product.

Pretty good but tip get worn out fast

easy to use but the end brush flatten out quickly

I found this product easy to use. This pen is meant for grout but I used it around the seal of the bathtub. I used it on old grout & the seal around my bathtub. It made my tub area look cleaner. The seal around our bathtub overtime got dark water spots. Cleaning does not take care of the dark spots, so I used grout paint pen looks better. I did a test spot first before applying all around the tub area. I would recommend this product & will buy again.

I purchased this grout pen for the grout in my shower tile. The grout was stained orange and no amount of scrubbing would change that. Eventually I want to redo my entire shower, but until then, I needed a quick fix. This grout pen worked perfectly. Not only was it super easy to use (think of a paint marker where you just have to pump the tip down a few times and to get it flowing), but it made an instant difference. I got some on my arm by not being careful while sprawled out on my shower floor at 2 am working on this project but it washed off with soap and water. However, I’ve taken several showers since painting the grout and that has NOT washed out. I haven’t actually scrubbed my shower since painting, so I will update my review if the scrubbing action causes the paint to come off.

Not as described Get the wide version not the narrow one

The only issue I have is the brush wore out too soon, but it did work very well, and I had to go over the grout twice. I may purchase another or see if they offer a new brush.
