## 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 100 feet of wide grout lines
- 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product and price is reasonable!
*by J***O on May 29, 2025*

Works great! Love this product! First I used on bathroom floor tiles. Refreshes the grout like new and last more than a year. Easy to apply. I also purchased a light gray for the stones in the bottom of the shower. I haven’t used the product yet. I am sure it will have to be replaced more often since the floor is scrubbed often. I will follow-up after application.

### ⭐⭐⭐⭐⭐ Best One I have Found For Kitchen Tile Counters - Vintage Kitchen Style
*by I***B on August 22, 2024*

Nice finish, easy to work with, clean look, less mess, precise pens, wide and slim. Does not run out fast, does not require constant pumping to get it to cover. Easy to use, not messy at all. I use it on large, white tiles that get a lot of wiping off and cleaning up daily. Is not wearing it out. All the things I said are my experiences with other brands that did not work or wore out when wet a couple times, that looked a bit dull. Great product, nice color choices too.

### ⭐⭐⭐⭐ AMAZING, VERY GOOD PRODUCT TO MAKE FLOORS LOOKS NEW AGAIN
*by V***5 on March 23, 2020*

This product is amazing, my kitchen and bathroom floors over time were look old due to grout's color changed from light color to dark, after applied this product over the previous grouts with a light color such as light grey, it gave me the new and clean look again, imagine if I had to hired the floor labor in tradition way to remove and reapplied a new grout, it may cost money and time consuming for sure but this pen did an amazing job in easy way and faster compared to the traditional, more than that anyone can do it, like me an old lady with very limited strength, I never imagined that I can renew my floor myself without this product, yes I suppose to give this product 5 stars with all the features I have listed above but there is some flaws, a- not easy to clean as described, once the color settled/dried out , it's very hard to remove the excess color with water, b-the capacity length use in package may be shorter, as I had all around 40 meters medium length grout, I have used 1 large and 1 small pen with 1 layer, the two pens almost empty if not there is a little in there, therefore I remove 1 star, if you prefer more layer expect to buy more quantity
