## Description

Grout Pen White Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - White, Narrow 5mm Tip (7mL) - White Grout Marker - desertcart.com

## 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: 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

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

**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.
