Review: Remarkable little grout pen! - Why did you pick this product vs others?: Great product! I used it to give my fireplace tiles a face-lift from dirty white to black. It got the job done and it looks amazing. Ps. I tried a black permanent marker to see if it would have the same effect and it doesn't!

## 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
- 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

## 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

### ⭐⭐⭐⭐ Awesome and Easy Grouting
*by J***R on February 4, 2024*

I liked that it was TRUE BLACK. It went on black & dried black in minutes. Doesnt smell and the single large pen was enough to complete my entire counter top grouting. Couple of "could be better" things. The large tip is very big. (1) If they just included the smaller tip it would be perfect. Suggest scraping away any excess grout before it dries, otherwise you may have to scrub for clean lines. (2) They should include cleaning steps for excess or grout spillage. Its washable, but with some effort. After first attempts , I ended up using the large tip.on its side. It dried true black quickly (photos), but I definitely recommend waiting the 6 hours before getting tiles wet. Bottom line: I am happy with the results. I would buy the smaller tip pen for any tiles smaller than 10x10. My tiles are 12x12 and the tip was even too big for the grout lines. Finished grout looks clean & definitely black. Would recommend.
