Review: Wow! Worked perfectly! - Wow! We are listing our house for sale and the black grout was showing dirt and a little dingy looking. I didn’t want to regrout the entire bathroom so I decided to try a grout marker. It worked better than expected! Easy to use, quicker than expected, covered well, and covered the entire bathroom with 1 marker. Very happy with how this turned out! Saved me a ton of time and hassle!
Review: Works Great - This worked perfectly for my project. I painted tiles and need something that would define the lines and this did the trick.

## 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: Would this be safe for granite tile provided that the tiles are sealed?**
A: I used it on the grout between my granite tiles. The tiles aren't sealed. I reviewed it here: http://juliecache.com/2014/03/08/new-and-improved-backsplash-and-counter/.html The black color hasn't faded yet.

**Q: I have white grout now will this change the color to black? That's what I want to do**
A: Yes. It is like paint so you'll want to be careful not to get the black on your tile.

**Q: Once applied, how do I keep tiles clean?**
A: Clean the floor tiles the way you normally do.  The grout stays black. Although. I probably wouldn't use a bleach based cleaner.

**Q: how many pens are needed to do grout for wall tile 4 feet tall by 40 feet length**
A: 2

### ⭐⭐⭐⭐ Pretty Good
*by J***. on May 18, 2020*

I used this stain to cover a dark blue grout after we updated our bathroom and the color scheme for the grout needed to be black. I am happy overall with the quality of the stain and ease of use of this product and would recommend it. The downside is the pen only contains 7 ml of stain, which doesn't go very far. Also, the pen tip (nib) tends to deteriorate when being used on coarse grout. I found that the tip was toast about the time the pen ran out of stain. I don't know if that is intelligent design or just luck. I tried not to press too hard when using the tip to extend the life of the pen tip. It is also a bit messy to use, if you over-stain onto the tile you need to get it up right away. The instructions say to use a moist cloth, but that just smeared the stain all over the place. I used my finger and a dry towel, which seemed to work the best. I think this stain would warrant a 5-star ranking if the pen barrel was larger and/or contained more stain. Come on, at give the customer a pen containing at least 10 ml, don't be cheap! If it had even 10 ml, it would increase pen coverage 30 percent and not cost the manufacturer hardly anything. I used three pens to cover approximately 70 square feet (about $30 with tax). I saw bulk grout stains containing 8 oz for sale on Amazon for as low as $30 (though some were not rated very well). BTW, for those of you who don't do metric, 7 ml is just under a quarter of an ounce (.24 oz).
