Grout Pen Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Narrow 5mm, 2 Pack with Extra Tips (7mL) - Grey

I should have taken a before and after picture. This pen is amazing! I wanted to change our white grout to black but went ahead and chose white. I tried everything to clean out the grout using toothbrushes, steam cleaners and it was useless! We did clean before using the grout pen and it was not as time consuming as I thought it would be. Super easy to use and the bathroom looks amazing! It makes it look and feel so clean!

I have a huge kitchen, hearth room, hall, 1/2 bath and laundry room that have light colored tile floors. The 20 year old grout was originally light, but over time had turned dark. I included a before/after pictures so you can see the difference. I decided I would paint over the grout and I chose this product because it got the best reviews. I hand painted every inch of the grout and used 9 paint pens in the process. I worked 2-3 hours at a time and finished the project in 3 days (Appx. 10 hours of work total). I chose the cream color, which was perfect. The pen works great and comes with extra tips so when you wear it down you can replace it. I have rough grout, so the tip of the pen frayed pretty quickly, but it worked even better for me that way. It's easy to apply and looks great! I highly recommend this product.

Oh boy... I didn't know what I was in for buying these. My grout is off-white and wearing down in some places. It had some stains here and there. All in all, the grout in my kitchen looked terrible and it was driving me crazy.I thought I would buy these pens to do some touch ups. So first of all, if you think you are going to buy one of these pens to do some touch ups, you are wrong. There is only a 1 in a million chance that whatever pen you buy is going to match your grout perfectly. I got the ivory color pen thinking I could do some touch ups, but it was WAY brighter than my seemingly ivory colored grout.Well... I guess I was in for doing the entire floor. Let me tell you, with a busy life, it has taken me ages to complete my floor, and I'm still not done.The reason I'm giving this product 4 stars instead of 5, is because the pens just don't last very long and perhaps not engineered quite right. The description says it lasts 150ft with 2mm grout. First off, I would never use this pen on grout that small, because the tip is going to cover about 4mm. My grout is about 8-10mm wide, requiring 2 strokes for each line of grout. I can't quite say if the pens live up to the lifespan they are supposed to. It is impossible to tell if the reservoir inside is under-filled or not. All that to say, it feels like these pens run out way too early and don't live up to the longevity in the description.I think that my kitchen/ small dining area is about 160 square feet. With doing two passes on each line of grout, and my tiles being approx. 12" long, that's about 320 feet of lines to cover. However, I'm back here to buy another 2 pack to finish my floor, which will be my 6th and 7th pen. By the specs in the description, it should have taken me no more than 4 pens.But I do have to say.... My floor does look great and it's a wonderful improvement. I don't have the time or desire to regrout my kitchen floor. In fact, I think it's a terrible idea to have grout in a kitchen and would some day like to put down vinyl. The pens definitely brought my floor back to new and I will keep a pen on hand to do some touch ups, which is already needed since every time you drop a piece of food, it stains the grout. Not sure who thinks grout in a kitchen is a great idea but it was already here when I moved in.All in all, here is my take away from the pens:1. Be prepared to do your entire floor2. Be prepared for a long-ish project if your floor is bigger. This is not going to be a quick fix. What took a while for me is having to let parts dry so you don't scoot into the wet paint, and having to come back to it later.3. Be prepared to buy more pens than you think you will need4. The end result is very good in my opinion

What can I say? Wow? Spectacular? Underrated? All of these things I suppose!! This grout cleaner has worked phenomenally on my dirty grout in my house that I just moved into! I cannot believe the difference. It looks like a totally different floor. The only thing is that it does go on a little bit like paint and it gets on the tile so it does take a little bit more tedious dedication if you want to do small tile floor like I have.

I’d give this product 3 out of 5 stars. While it does cover the grout and offers a quick fix, I think simply painting the tiles would have provided a more cohesive and polished look for my bathroom. The product comes with two pens, but after using them, I realized I’d need many more to cover the entire bathroom—despite it being a small space. This is more suited for smaller areas with narrow grout lines. Unfortunately, it didn’t meet my needs for a larger project. If you have a tiny space and just want a quick touch-up, it could work, but it wasn’t quite right for what I was hoping to achieve.

UNBELIEVABLE! I'm totally shocked! Easy to put on, no harsh smells. Time-consuming, yes, worth it YES!!! Not sure how long it will hold up but I'm not worried about it as the installers years ago used the wrong shade of grout.

Easy to use and made a dramatic difference with the old tile in my bathroom and it still looks good months later
