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 | B06XRW89GK | | Best Sellers Rank | #159,219 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #707 in Tile Grout | | Brand Name | RAINBOW CHALK MARKERS LTD | | Colour | Grey | | Compatible Material | Grout | | Country of Publication | USA | | Customer Reviews | 4.2 4.2 out of 5 stars (4,416) | | Included Components | Grout Pen | | Item Dimensions | 9.5 x 1.4 x 19 Centimeters | | Item Form | Pen | | Item Weight | 25 Grams | | Manufacturer | Rainbow Chalk Markers Ltd | | Manufacturer Part Number | GP81114 | | Material Type | Grout Paint | | Model | GP81114 | | Number of Items | 1 | | Number of Packs | 1 | | Style Name | Compact | | Supported Standards | ASTM-D4236 | | Surface Recommendation | Tile | | Unit Count | 1.0 Count | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** RAINBOW CHALK MARKERS LTD - **Item Weight:** 25 Grams - **Item dimensions L x W x H:** 9.5 x 1.4 x 19 Centimeters - **Material:** Grout Paint - **Style:** Compact ## Images ![Grout Pen Light Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Light Grey, Narrow 5mm Tip (7mL) - Image 1](https://m.media-amazon.com/images/I/71lPj+03R-L.jpg) ## Frequently Bought Together - Grout Pen Light Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Light 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) - Grout Pen Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Grey, 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.com.pa/products/458276881-grout-pen-light-grey-tile-paint-marker-waterproof-grout-paint](https://www.desertcart.com.pa/products/458276881-grout-pen-light-grey-tile-paint-marker-waterproof-grout-paint) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-13*
