## Description

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

## 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
