Review on 💦 Waterproof Grey Tile Grout Pen: 5mm Colorant and Sealer Marker - Narrow Tip (7mL) by Obhed Mac

money well spent! We just moved into an 18 year old house and have cleaned and painted almost every surface. I tried everything I could find to clean the grout to make it look modern like the rest of the house but it still looked dirty 😝 Then I found this product and the heavens opened! Hallelujah, thank you Jesus! I think the photos speak for themselves, but WOW! I've started doing the laundry in case anything goes wrong, but I can safely say I'll take care of my kitchen and bathrooms from now on! I intend to seal it after all is said and done. I used a 20mm gray pencil. I still have lines to do in the washer and dryer but I'm pretty sure there's enough left to finish. Thus, one pin will suffice for a space approximately 7 feet by 9 feet. Make sure you only do a few lines at a time by wiping off the excess with a damp paper towel or rag. Took me about 3 hours to do what you see but that's also with two toddlers running around 🤪 Oh and I suggest wearing gloves because it's messy. But it's worth it!
