Pen cap represents each pen's color but is not expected to be the exact shade, do a small test area first - USE ON UNSEALED GROUT ONLY: GROUT PEN may not bond to sealed grout. Test grout with a few drops of water. If the grout does not absorb the water within a minute this means the grout is likely sealed. - TIP MAY WEAR DOWN: Tip is made of cotton, pressing too hard will damage tip. Contact seller for replacement tips if needed - SHAKE ONLY WITH CAP ON: Tip is removable and may fall out if shaken hard, only shake pen with cap on (note - Pen does not need to be shaken at all, instead gently pump tip to activate) - DRY TIP: Pen needs to be primed before use, all new GROUT PENs come with a dry white tip. To activate rapidly pump the tip (30+ times) until fully saturated ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071LTCQJJ | | Best Sellers Rank | #10,404 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #15 in Tile Grout | | Brand | Rainbow Chalk Markers Limited | | Brand Name | Rainbow Chalk Markers Limited | | Color | Light Grey | | Compatible Material | Grout (Unsealed) | | Customer Reviews | 4.2 out of 5 stars 5,899 Reviews | | Included Components | GROUT PEN | | Item Dimensions | 1.25 x 1.25 x 6.25 inches | | Item Form | Pen | | Item Weight | 79 g | | Item dimensions L x W x H | 1.25 x 1.25 x 6.25 inches | | Manufacturer | Rainbow Chalk Markers Ltd | | Material | Grout Paint | | Material Type | Grout Paint | | Model | GP81114S | | Number of Items | 1 | | Part Number | GP81208 | | Style | Modern | | Style Name | Modern | | Supported Standards | ASTM-D4236 | | Surface Recommendation | Tile , Floor, Tub, Shower, Countertop, Backsplash, Sink, Wall, Patio | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Rainbow Chalk Markers Limited - **Item Weight:** 79 Grams - **Item dimensions L x W x H:** 1.25 x 1.25 x 6.25 inches - **Material:** Grout - **Style:** Modern ## Images ![Grout Pen Light Grey Tile Grout Paint Marker - Wide 15mm Tip (20ml) - Image 1](https://m.media-amazon.com/images/I/71pQdA+E2EL.jpg) ![Grout Pen Light Grey Tile Grout Paint Marker - Wide 15mm Tip (20ml) - Image 2](https://m.media-amazon.com/images/I/716lql2SCuL.jpg) ![Grout Pen Light Grey Tile Grout Paint Marker - Wide 15mm Tip (20ml) - Image 3](https://m.media-amazon.com/images/I/71QC5fppUtL.jpg) ![Grout Pen Light Grey Tile Grout Paint Marker - Wide 15mm Tip (20ml) - Image 4](https://m.media-amazon.com/images/I/81OQpHHVl1L.jpg) ![Grout Pen Light Grey Tile Grout Paint Marker - Wide 15mm Tip (20ml) - Image 5](https://m.media-amazon.com/images/I/71X9GU3b+tL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Grout Pen *by F***R on July 15, 2026* It was the exact color and was very easy to apply. ### ⭐⭐⭐⭐⭐ Recommend *by A***N on July 27, 2026* Worked great ### ⭐⭐⭐⭐ AMAZING, VERY GOOD PRODUCT TO MAKE FLOORS LOOKS NEW AGAIN *by V***5 on March 23, 2020* This product is amazing, my kitchen and bathroom floors over time were look old due to grout's color changed from light color to dark, after applied this product over the previous grouts with a light color such as light grey, it gave me the new and clean look again, imagine if I had to hired the floor labor in tradition way to remove and reapplied a new grout, it may cost money and time consuming for sure but this pen did an amazing job in easy way and faster compared to the traditional, more than that anyone can do it, like me an old lady with very limited strength, I never imagined that I can renew my floor myself without this product, yes I suppose to give this product 5 stars with all the features I have listed above but there is some flaws, a- not easy to clean as described, once the color settled/dried out , it's very hard to remove the excess color with water, b-the capacity length use in package may be shorter, as I had all around 40 meters medium length grout, I have used 1 large and 1 small pen with 1 layer, the two pens almost empty if not there is a little in there, therefore I remove 1 star, if you prefer more layer expect to buy more quantity ## Frequently Bought Together - Grout Pen Light Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Light Grey, Wide 15mm Tip (20mL) - Grout Pen Light Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Narrow 5mm, 2 Pack with Extra Tips (7mL) - Light Grey - 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.sc/products/50151372-grout-pen-light-grey-tile-grout-paint-marker-wide-15mm](https://www.desertcart.sc/products/50151372-grout-pen-light-grey-tile-grout-paint-marker-wide-15mm) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-08-10*
