## 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 100 feet of wide grout lines
- 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

### ⭐⭐⭐⭐⭐ Great product

### ⭐⭐⭐⭐ Works as described, color is a bit off.
*by D***D on February 16, 2026*

The pen is easy to use, covers old grout completely and dries quickly. So far, after being mopped several times, the durability is great! My only complaint is that I ordered the grey grout pen, however the final color has a bluish tint.
