Want to spruce it up but don’t want to mess with bleach solutions or regrouting? Completely transform your tile grout with the Grout Pen, a safe and simple solution that lets you clean up grubby grout without the hassle. No scrubbing, bleaching, power washing, or regrouting required. Simply pump the pen until the paint starts flowing through the nib and get to coloring! USE ANYWHERE Cleaning and coloring grout has never been easier and you’ll love how the renewed lines give your home an instant makeover. Use the Grout Pen on the tile in the bathroom to freshen up the appearance of your shower, bathtub, sink, or windows. Take the pen to the kitchen and add a pop of color to tile counters, floors, or oven backsplashes. No grout is off limits! Once you’ve fully restored your grout, the pen can be used as a touch-up solution whenever needed. LONG LASTING INK Quickly change the color of your grout lines with a pen that’s designed to last. Our 15mm pen can cover up to 100 feet of wide grout lines to tackle DIY projects of every size and feature a reversible nib to handle sanded and unsanded grout lines. The fast-drying paint will be touch-dry after 30 minutes, but to ensure the best results allow the paint to settle into the grout for 2 hours. RICH PIGMENTS Available with a 5mm or 15mm bullet nib, Grout Pen can cover thin and thick grout tracks. Choose from one of our 11 popular grout colors: white, black, winter grey, light grey, grey, dark grey, brown, cream ivory, terracotta, and beige. ADVANCED FORMULA The paint used is carefully designed using a water-based formula that covers grubby grout making it look brand new while delivering richly pigmented colors. Non-toxic and safe to use in enclosed spaces, the Grout Pen is an environmentally friendly option that allows you to quickly complete your home improvement upgrades!. Review: Easy to use, great results, and surprisingly durable - Results were better than I expected, and applying it was easier than I expected. I bought this item four years ago, and applied it at that time, and now four years later I am returning to get the same item again to touch it up. I used it on my kitchen floor which gets heavy use, and it held up surprisingly well. I would not have even touched it up except for the fact that I am currently cleaning and sealing the tile, so I figured I might as well touch up the grout while I'm at it. Great product, highly recommend. Review: Really impressed. - I must admit, I was very sceptical about how good this would be, but it was either that, or rake out and re-grout. The existing grout (floor tiles) had badly discoloured from its grey, and looked horrible. I'd tried all the usual things, bicarb / white vinegar etc., to no real avail. This done the job perfectly. Like most things, you need to take your time and wipe any excess from the tile (using dry kitchen towel works great - not damp cloth, which will just smear it). Minor niggle is that the applicating nib (bit like a felt tip) would ideally be angled to make it easier to get into corners. I found a way round this by depressing a few times in a washed out yoghurt pot so you get a little liquid forming, and then use an artists paint brush. This allows you to get right into corners. Love this, great product! ## Features - Item Category: Sealant - Item Trademark: Rainbow Chalk Markers Ltd - manufacturer: Generic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007D0J0CY | | Best Sellers Rank | #142,796 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #392 in Tile Grout #970 in Flooring Products | | Brand | Rainbow Chalk Markers Limited | | Brand Name | Rainbow Chalk Markers Limited | | Color | Dark Grey | | Customer Reviews | 4.2 out of 5 stars 1,107 Reviews | | Ink Base | Water | | Ink Color | Dark Grey | | Ink colour | Dark Grey | | Item Dimensions | 32 x 32 x 159 millimeters | | Item Weight | 79 Grams | | Manufacturer | Rainbow Chalk Markers Limited | | Manufacturer Part Number | GP81216 | | Material Type | Resin | | Model Number | GP81216 | | Number of Items | 1 | | Number of Pieces | 1 | | Recommended Uses For Product | Painting | | Recommended uses for product | Painting | | Style | Compact | | Surface Recommendation | Tile | | Surface recommendation | Tile | | Target Audience | Adult | | Target audience | Adult | | UPC | 722480212161 | | Unit Count | 1.0 Count | | Water Resistance Level | Waterproof | | Writing Instrument Form | Marker Pen | ## Product Details - **Brand:** Rainbow Chalk Markers Limited - **Item dimensions L x W x H:** 32 x 32 x 159 millimeters - **Item weight:** 79 Grams - **Material:** Resin - **Style:** Compact ## Images ![Rainbow Chalk Markers Limited Grout Pen Large Dark Grey - Ideal to Restore the Look of Tile Grout Lines - Image 1](https://m.media-amazon.com/images/I/71F6uMyemxL.jpg) ![Rainbow Chalk Markers Limited Grout Pen Large Dark Grey - Ideal to Restore the Look of Tile Grout Lines - Image 2](https://m.media-amazon.com/images/I/71Khb8ymIIL.jpg) ![Rainbow Chalk Markers Limited Grout Pen Large Dark Grey - Ideal to Restore the Look of Tile Grout Lines - Image 3](https://m.media-amazon.com/images/I/71QC5fppUtL.jpg) ![Rainbow Chalk Markers Limited Grout Pen Large Dark Grey - Ideal to Restore the Look of Tile Grout Lines - Image 4](https://m.media-amazon.com/images/I/81AwUVvn2wL.jpg) ![Rainbow Chalk Markers Limited Grout Pen Large Dark Grey - Ideal to Restore the Look of Tile Grout Lines - Image 5](https://m.media-amazon.com/images/I/71X9GU3b+tL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use, great results, and surprisingly durable *by S***K on 30 May 2026* Results were better than I expected, and applying it was easier than I expected.
