Review: FANTASTIC!! - Oh my! This pen is wonderful. I did my kitchen floor with one pen—light grey. Color was perfect My grout was impossible to get clean I tried everything. Bleach applied with a Q-tip. Rubbed with an old toothbrush. Baking soda, nothing worked. I figured I had nothing to lose and the majority of the reviews were positive. I can’t believe how clean my floor looks now. The first 3 pictures show it half way through. Last 2 are it completed. I had no problems with the tip falling out or fraying. I do recommend this pen!
Review: Very good product - This product saved me money and time. My grout is two years old and I used several products to clean it.. (ie. )baking soda and peroxide, Oxyclean,and a vinegar based cleaner with negative results. I was reluctant to try the grout pen because some of the reviews stated it was hard to use and the tip didn't last long. Well I'm so glad I tried. I did my kitchen and a half bath with no problems. You really have to follow the directions completely and it will work fine. I used a paper plate to prime the pen each time the paint didn't flow out freely. Just keep priming the pen and don't press down too hard and it will work fine. I used the winter grey . I did one coat and let it dry for one hour then went over it again. My only concern is how long will this pen keep my (floors /grout ) looking good and refreshed. I would redo this process ever year if I had to. Will give an update later to let you know if its last 3 weeks or 3 years. I did e-mail the company RAINBOW CHALK , and asked if I needed to seal the grout chalk to keep it from staining and they replied No. So only time will tell. UPDATE: It's January 2023 and I'm reapplying another coat from 2020. Only because it started to look a little worn. I really didn't have to do the entire kitchen over but I wanted a uniformed look. This pen is excellent. I don't need to re-touch my half bath, for some reason it still looks good. This time I'm not going to clean my kitchen floors with nothing but really hot steaming water. I mop my floors practically every night and found that different chemicals aren't necessary. In addition I purchased the O-Cedar mop and bucket combo and it works great. Note: I was not paid for this review!

## Features

- LOOK BRAND NEW: Skip scrubbing tiles and use GROUT PEN to paint and recolor your grout for a bright clean appearance
- USE ANYWHERE: Ideal for the bathroom, kitchen, and any other room that has floor or ceiling tiles
- LONG LASTING INK: Tackle small or large DIY projects with a pen that covers up to 150 feet of thin 2mm grout
- ADVANCED FORMULA: Non-toxic, water-based colorant that covers grubby grout stains making it look brand new again
- CAP COLOR: Use the color chart (see images) for most accurate color depiction. Pen cap represents each pen's color but is not expected to be the exact shade, do a small test area first
- USE ON UNSEALED GROUT ONLY: GROUT PEN may not bond to sealed grout. Test grout with a few drops of water. If the grout does not absorb the water within a minute this means the grout is likely sealed.
- TIP MAY WEAR DOWN: Tip is made of cotton, pressing too hard will damage tip. Contact seller for replacement tips if needed
- SHAKE ONLY WITH CAP ON: Tip is removable and may fall out if shaken hard, only shake pen with cap on (note - Pen does not need to be shaken at all, instead gently pump tip to activate)
- DRY TIP: Pen needs to be primed before use, all new GROUT PENs come with a dry white tip. To activate rapidly pump the tip (30+ times) until fully saturated

### ⭐⭐⭐⭐ Not for Shower Floors!
*by R***N on February 3, 2026*

NOT FOR USE IN SHOWERS This is a great product for floor or wall repair, but given it's water-soluble, it should not be used in wet areas. I used it on my bathroom floor and it worked great. It’s easy to apply. The one thing to be aware of it that you should have a dense sponge (like a “magic eraser”) and once you go over the line, pass over it again with the sponge to even it out. Looks great. I tried it in my shower, however, and it's terrible. It lasts a couple of days, then it starts to flake off. My grout has an interesting color - when it's dry it's almost white (and a perfect match to this gray), but when it gets wet, it turns dark gray (almost black), so, where the product flakes off, you see black portions of the grout coming through. It looks like mold! The treatment seems to last no more than a couple of days. I've tried re-treating it and then sealing it with a clear grout sealer, all to no avail. It's just not strong enough for a shower floor. As I said, the rest of the bathroom seems just fine, it's just the shower floor that seems to suffer. Upside is that it removes pretty easily - I took a nail brush and some alcohol and got most of it up. Now looking for a different solution. Pros: - great match to my grout - easy to apply Cons: - Flakes off if used in a shower Recommendation: OK to use in other parts of the bathroom or kitchen, but not where standing water will collect.
