## Features

- 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: Is this product waterproof or will it wash away if I apply it to the shower floor tiles?  tia**
A: Yes Grout Pen is waterproof.  Grout Pen is specifically design for wet areas including showers, bathroom floors, around sinks, kitchen counter and backslash.

LOOK BRAND NEW AGAIN: 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
RICH PIGMENTS: Grout paint markers available in 11 different colors with reversible 5mm Narrow or 15mm Wide nibs
ADVANCED FORMULA: Non-toxic, water-based ink that covers grubby grout stains making it look brand new again

**Q: Can you put sealer over it?**
A: Nope. It looked beautiful until I put a sealer over it. (I should have searched for "sealer" before I even bought it. :-( ) Don't waste your money.

**Q: Does it work on silicone caulk?**
A: Silicone caulk is not paintable so this product would likely not work on it.

**Q: does it work on marble tiles grout?**
A: Yes, it works on grout, but it does not last long. I would guess a white sharpie would work just as well.
