I have used 4 pens for my kitchen which is roughly 12 by 18ft. Hope this helps **Q: Is the touch up considered permanent or semi-permanent or will wash away with cleanings?** A: Good question. For most grouts it is permanent. However some customers try it on "sealed" grout and it is not able to adhere with the grout, therefore it is temporary. **Q: Will this product fill in fine cracks in the grout? My back splash grout ling that meets my counter top has a small crack line.** A: If the cracks are VERY fine, the grout pen may fill them, but this does not apply to silicon grouting, which is generally used to seal the line between counter top and wall. The grout pen is meant for mortar grout. **Q: Will this work on painted grout?** A: Yes GROUT PEN will work over painted grout (unless oil paint was used prior, but that is unlikely). 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 ink that covers grubby grout stains making it look brand new again NOTE: Grout Pen may not bond to sealed grout. Test the porosity of the grout with a few drops of water. If the grout does not absorb the water drops within a few minutes, this indicates that the grout was probably sealed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than therapy *by on Reviewed in the United States August 16, 2019* This was the most incredibly soothing and least frustrating home improvement product I have ever tried.My kitchen gray slate tiles had green (ugh) grout when I bought the place - this made the grout look moldy.I bought the gray pen (slightly lighter than the tiles). It was easy to put on, didn't make a mess and the floor looks a billion times better - and it was really kind of fun.Tips.Really clean the grout first. I scrubbed with a grout brush, vacuumed steamed and then vacuumed again. Probably overkill, but the cleaner it is the better it works.I did a 5X10 ft area with the smaller pen and there was enough left to do a bit more.Shake the pen, then press down on cardboard till the tip is covered in grout. For consistent application, press down again to re-cover the pen at every tile intersection.Drag the pen tip slowly, more like a paint brush , rather than digging into the tiles.I didn't have to mask anything, but have a paper towel ready - cleaning up the wet stuff is easy, once it dries - well, it is grout.Since my pen color was lighter than the original grout color, I let it dry for one day and then vacuumed and did one more coat - that made it look virtually like a professional job.Did I mention that this was totally soothing?Can't speak to longevity yet, but this is so simple and painless and cheap that if it had to bee redone, no problem.If only all my home repairs were like this ### ⭐⭐⭐⭐⭐ Grout Pen *by on Reviewed in the United States September 27, 2025* Good coverage of discolored or worn grout. Maintains its color even after washing the floor. (Would not scrub it though.) Bought two colors and was glad I did because the lighter gray was too light. If the grout line is narrow you have to be a little careful in its application not to have it get onto the surface of the tile. If it does, allow the pen ink to soak into the grout for a couple minutes then carefully wipe it from the tile with a damp cloth. ### ⭐⭐⭐⭐ Not for use in wet areas *by on Reviewed in the United States February 3, 2026* NOT FOR USE IN SHOWERSThis is a great product for floor or wall repair, but given it's water-soluble, it should not be used in wet areas.I used it on my bathroom floor and it worked great. It’s easy to apply. The one thing to be aware of it that you should have a dense sponge (like a “magic eraser”) and once you go over the line, pass over it again with the sponge to even it out. Looks great.I tried it in my shower, however, and it's terrible. It lasts a couple of days, then it starts to flake off. My grout has an interesting color - when it's dry it's almost white (and a perfect match to this gray), but when it gets wet, it turns dark gray (almost black), so, where the product flakes off, you see black portions of the grout coming through. It looks like mold! The treatment seems to last no more than a couple of days. I've tried re-treating it and then sealing it with a clear grout sealer, all to no avail.The product is just not strong enough for shower floor. As I said, the rest of the bathroom seems just fine, it's just the shower floor that seems to suffer.Upside is that it removes pretty easily - I took a nail brush and some alcohol and got most of it up.Now looking for a different solution.Pros:- easy to applyCons:- Flakes off if used in a showerRecommendation: OK to use in other parts of the bathroom or kitchen, but not where standing water will collect. ## Frequently Bought Together - Grout Pen Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Grey, Narrow 5mm Tip (7mL) - Grout Pen Dark Grey Tile Grout Paint Marker: Waterproof Tile Grout Paint Pen Colorant, Grout Shine Touch Up & Renew - Dark Grey, Narrow 5mm Tip (7mL) - Grout Pen White Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - White, Narrow 5mm Tip (7mL) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/10800427-grout-pen-grey-tile-grout-paint-marker-restorer-narrow-5mm](https://www.desertcart.co.za/products/10800427-grout-pen-grey-tile-grout-paint-marker-restorer-narrow-5mm) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-11*
