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 5mm pen can cover up to 150 feet of 2mm narrow 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: Small - It is good for small area, but not enough for larger area, need to buy many pens, but it is expensive Review: I was sceptical, but this product really delivers. My shower looks brand new! Very easy to use, just shake it up and start filling in lines. The narrow nib means there is nothing to clean up either. I highly recommend this product, exceeded expectations. ## 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 150 feet of thin 2mm grout - 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.

It looked beautiful until I put a sealer over it. (I should have searched for "sealer" before I even bought it. :-( ) Don't waste your money. **Q: Does it work on silicone caulk?** A: Silicone caulk is not paintable so this product would likely not work on it. **Q: does it work on marble tiles grout?** A: Yes, it works on grout, but it does not last long. I would guess a white sharpie would work just as well. ## Customer Reviews ### ⭐⭐⭐ Small *by G***N on 27 March 2025* It is good for small area, but not enough for larger area, need to buy many pens, but it is expensive ### ⭐⭐⭐⭐⭐ Review *by S***. on 21 October 2025* I was sceptical, but this product really delivers.
