Tips need to be primed before use, all brand-new Grout Pens have a dry white tip until they are activated. The tip of my Grout Pen fell out or is worn down, is my pen broken? Tips are designed to be removable so when a tip becomes worn or damaged it can be taken out and flipped over. If the tip falls out do not worry, simply put it back in and keep working. Do I need to press down hard while moving the pen along the grout lines? Pressing hard will damage the tip. It's better to prime the pen by pressing up and down until the ink flows to the tip. Once the tip is fully saturated, lightly move the pen across the grout line. The colour of the pen cap is not exactly the colour I want The Grout Pen colour chart is a good representation, please keep in mind that computer screens can display slightly different colour spectrums, it is recommended to do a small test area first if you are not sure about the colour. ## Features - Restores Tile Grout and leaves them looking clean and protected - Change Colour of your Tile Grout Lines - 2 pens Cover up to 120 meters of 2mm width grout lines - Anti-bacterial agents help prevent mould from re-appearing - Ideal for floors & walls in Kitchens and Bathrooms ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B09GG6XJ1N | | Best Sellers Rank | 5,460 in DIY & Tools (See Top 100 in DIY & Tools) 20 in Tile Grout | | Brand | RAINBOW CHALK MARKERS LTD | | Colour | Dark Grey | | Compatible Material | Ceramic, Porcelain, Concrete | | Customer Reviews | 4.3 4.3 out of 5 stars (803) 4.3 out of 5 stars | | Item Dimensions | 9.5 x 1.4 x 19 centimetres | | Item Form | Pen | | Item Weight | 25 Grams | | Manufacturer | Rainbow Chalk Markers Ltd | | Manufacturer Part Number | GP81116/2 | | Material | Water Based | | Model Number | GP81116/2 | | Number Of Items | 1 | | Number Of Packs | 2 | | Product Warranty | 30 days | | Style Name | Cover Up | | Surface Recommendation | Tile | | Unit Count | 14.0 millilitre | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** RAINBOW CHALK MARKERS LTD - **Item dimensions L x W x H:** 9.5 x 1.4 x 19 centimetres - **Item weight:** 25 Grams - **Material:** Water Based - **Style:** Cover Up ## Images ![Twin Pack (DARK GREY) Grout Pen - Designed for restoring tile grout in bathrooms & kitchens - Image 1](https://m.media-amazon.com/images/I/81EbwUQRBYL.jpg) ## Questions & Answers **Q: The Grout Pen I received has a dry white tip, is it broken or did I receive the wrong colour?** A: Tips need to be primed before use, all brand-new Grout Pens have a dry white tip until they are activated. **Q: The tip of my Grout Pen fell out or is worn down, is my pen broken?** A: Tips are designed to be removable so when a tip becomes worn or damaged it can be taken out and flipped over.

I had high hopes but low expectations. But this is fantastic all round. This was to smarten up the kitchen in our narrowboat. The walls slope in so I expected this to not work.But it did. I had to dab it fairly often but it was so worth it. Leave to dry then clean tiles. Looks amazing. ### ⭐⭐⭐⭐ Great but you need more than you think *by on Reviewed in the United Kingdom 24 May 2026* These are great, easy to use, i started off trying to draw inside the lines but i have slightly wavy tiles and i eventually found it easier to just draw on 'badly' and then wiping the excess off the tiles once dry. I absolutely love the outcome my only complaint and hence 4stars is that you can only get probably half the pen out because the nib gives up. i bought 4 and only got around just half of my small splash back. no amount if shaking or trimming the nib would help. you could sense there was still paint inside the pen but it was unusable ### ⭐⭐⭐⭐⭐ Grout pens *by on Reviewed in the United Kingdom 17 July 2026* Worked really well ## Frequently Bought Together - Twin Pack (DARK GREY) Grout Pen - Designed for restoring tile grout in bathrooms & kitchens - Twin Pack White Grout Pen - Designed for restoring tile grout in bathrooms & kitchens (White) - Twin Pack (GREY) Grout Pen - Designed for restoring tile grout in bathrooms & kitchens --- ## 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.no/products/371796159-twin-pack-dark-grey-grout-pen-designed-for-restoring-tile](https://www.desertcart.no/products/371796159-twin-pack-dark-grey-grout-pen-designed-for-restoring-tile) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
