Grout Pen Light Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Light Grey, Wide 15mm Tip (20mL) - desertcart.com

Review: Good product and price is reasonable! - Works great! Love this product! First I used on bathroom floor tiles. Refreshes the grout like new and last more than a year. Easy to apply. I also purchased a light gray for the stones in the bottom of the shower. I haven’t used the product yet. I am sure it will have to be replaced more often since the floor is scrubbed often. I will follow-up after application.
Review: Effective, Easy to Use Grout Paint - This grout paint worked great for my purpose. I had newer grout where the sealant failed and stained quite badly, quite quickly. This pen worked quickly and effectively to fix our entire kitchen floor. The narrow pen was perfect for my 1/8" grout, and I has zero issues with the tip wearing badly; this may be because our grout was unsanded so the pen glided easily over it. Based on the reviews, I elected to carefully wipe up any errant paint with a paper towel as soon as I was done with a line; doing this, the stray product cleaned up easily, but I had to be careful not to disturb the painted grout line using this method. Our tiles is glass smooth and glossy, which also made this easy. I also got the manufacturer's stated usage from the pen, but we did have the thinnest possible unsanded grout. The light gray definitely had a blue hue to it when compared to the original light cement gray grout, but it still blended quite well with the flooring in spite of this; it might look odd paired with warm-toned tiles that have no cool tones in them. Also, bonus points for zero fumes and the product being easy to prime and fairly easy flowing. Too soon to tell how well it holds up very long term, but so far, so good and I would definitely use this again, if needed.

## 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

### ⭐⭐⭐⭐ Helped make my old tile look new!
*by K***A on October 21, 2020*

So I ended up using 2 grout pens. This large light gray one and the small beige one. After my first cleaning of tile/grout and use of this pen I felt like the gray was too bright and it had a slight bluish hue. The last pic was the dirty tile I started with. The first pic is how it looked after I cleaned it and then used the light gray pen. The second and third pics are how it looked after I went back over the grout with the small beige pen. The two-toned contrast I ended up with is better than I could have imagined. I am very happy with the end result. My only complaint would be that the felt tips on these come out kind of easy. So you have to keep putting it back in. Other than that, i found them easy to use, long lasting, and well worth the affordable price.
