Review: Recommend - This stuff works very well and freshed up my whole bathroom look. It was very easy to use and you can go over the grout more than once if needed. One pen does a small bathroom, in my case anyway. Would recommend.
Review: Easy to use - Worked easy and matched my other grout perfectly

## 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

## Questions & Answers

**Q: Can this be used to fill cracks in grout?**
A: No this is not intended to fill cracks in grout

**Q: I'm confused.  This says it is a sealer, but someone asked if it prevented mold & you said doubtful?**
A: It's a waterproof grout colorant which, by definition, affords some degree of "sealing". As for preventing mold, surely that would require some sort of chemical content? Not sure what one can use to prevent mold on an ongoing basis except, perhaps for regular wipe downs with vinegar and water or other cleaning product.

**Q: Can it be used on swimming pool grout?**
A: Yes GROUT PEN can be used around the pool. Be sure to check and see if the pool has grout or mortar/concrete.  GROUT PEN will work on both but on mortar/concrete the coverage will be much less due to the rough and porous nature of mortar/concrete.

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
SEALED GROUT: Grout Pen may not bond to recently sealed grout. Test the grout with a few drops of water. If the grout does not absorb the water within a few minutes then the grout was 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 gently pump the tip (20-30 times) until fully saturated

**Q: How many square feet does one pen cover?**
A: Honestly it varies as grouts vary in their porosity and whether it has been treated or not.  The manufacturer states the 15mm pen will do up to 40 linear meters.

### ⭐⭐⭐⭐⭐ Easy to use
*by M***P on December 29, 2025*

Worked easy and matched my other grout perfectly

### ⭐⭐⭐⭐ Good for floors
*by L***M on August 9, 2025*

This product works great for floor tile. Not sure it will hold up with mopping, but it does look WAY better than before and easy to do, so if it doesn't hold up, I'll just repaint it. It is not good for shower tile, the pen doesn't work well unless it's being held straight up so the tile needs to be below it, like a floor, not a wall.
