## Questions & Answers

**Q: Can this be used over painted/sealed grout?**
A: I used on sealed grout and it worked great

**Q: What is the difference in the pen sizes? Does one contain more product or does it have a bigger tip?**
A: The Large Pen is 15mm wide (about the size of a typical Jumbo Marker).  The 5mm pen is about the size of a regular sharpie marker.

**Q: What size room does one pen cover?**
A: Good question.  The manufacturer states "up to 60 meters coverage for narrow grout joints".  60 meters is approximately 196 linear feet, however results vary as the porosity of grouts can very greatly.

**Q: Will this pen let me change the color of grout that is currently white but discolored? I want grey grout lines on my bathroom floor.**
A: Yes

I just finished my grout coloring projects today. I must say that I am very pleased with the grout pen(dark gray) so far. I purchased three pens for my kitchen backsplash and a shower wall. One wall in my shower has a dark gray grout, which in spots was beginning to discolor. I scrubbed and scrubbed, however, I could not bring the color back. I used a dark gray grout pen and colored all of the grout on that shower wall and it turned out great. It was easy to use, clean up of any excess on the tile was simple and the color looks great. See photos. Next, my kitchen backsplash. The backsplash is made up of white subway tile with white grout. The only problem is that the white grout became very dingy and yellowish over time. I used the same dark gray grout pens for the backsplash and it turned out amazing. See photos. The grout pens last a long time in my opinion. I used maybe one and a half pens for both my kitchen backsplash and shower wall. I even double coated near the kitchen sink and behind the oven for extra protection. It took me about 8 hours to do the kitchen and shower wall. My recommendation to you would be to complete your task, allow the grout to dry for an hour or so and come back to wipe down the excess color off of the tiles. With a damp cloth, the excess color wipes right off of the tiles. With a non-porous tile, you don’t need to worry about coloring outside the lines. It will not stain. Don’t wipe down after every bit of color you get on the tile, it will add so much time to your job. Wait until you’re all finished, then clean. I used microfiber towels, bundled up and damp. I worked it in circle motions through the tile wall, trying not to apply to much pressure to the grout lines. When the grout color is fresh, some may wipe off if you apply too much pressure directly to the grout. This is why I recommend waiting an hour + before wiping down. Allow it to settle into the grout. I started wiping too quickly after application and had to add some color again. After you clean up the excess color off of the tiles, examine for any touch up areas. There will likely be a few. Some reviews addressed the pen tip breaking. I never experienced this. During the color process, keep a paper plate handy to dab and prime the color into the pen tip. Do this often and you won’t need to press hard while coloring. I could see it breaking if you go all King Kong on it. I can’t speak for the durability of the product yet, but as time goes on, I will update my review. I may add a spray on tile/grout seal after a few days to help protect the color as well.
