- 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: How much area does 1 pen cover?**
A: It all depends on how many layers you apply, I did 3.  I have used 4 pens for my kitchen which is roughly 12 by 18ft.  Hope this helps

**Q: Is the touch up considered permanent or semi-permanent or will wash away with cleanings?**
A: Good question.  For most grouts it is permanent. However some customers try it on "sealed" grout and it is not able to adhere with the grout, therefore it is temporary.

**Q: Will this product fill in fine cracks in the grout?  My back splash grout ling that meets my counter top has a small crack line.**
A: If the cracks are VERY fine, the grout pen may fill them, but this does not apply to silicon grouting, which is generally used to seal the line between counter top and wall. The grout pen is meant for mortar grout.

**Q: Will this work on painted grout?**
A: Yes GROUT PEN will work over painted grout (unless oil paint was used prior, but that is unlikely). 

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 ink that covers grubby grout stains making it look brand new again
NOTE: Grout Pen may not bond to sealed grout. Test the porosity of the grout with a few drops of water. If the grout does not absorb the water drops within a few minutes, this indicates that the grout was probably sealed.
