I moved into my apartment and it was all white, I thought I would have a go at a grout pen and seeing if I could make it look better. These are so worth the money as the transformation of my bathroom is amazing! The coverage is great and they are very easy to use. I used these in January and it still looks the same so the pen liquid is very durable. It takes around 2 minutes to dry. The pens are the size shown on the advert, however one pen lasts a long time! Review: Easy application, instant impact! - These grout pens are the best way to transform your tiles! I have used in both bathroom and kitchen on white grout and they’re fantastic. Two pens were more than enough for the kitchen. For my shower tiles, approx 6 Sam I used 4. Not because the ink ran out, but because the nib starts to blunt and the drawing line becomes thicker. To keep the lines consistent I switch pens more regularly. Long lasting as well. The colour is black, as for it being waterproof it is to an extent. The kitchen area hasn’t required a touch up in 18 months. The bathroom, as it has shower watering hitting and more abrasive cleaner used does start to come off but a quick touch up every 6 months works well. Brilliant value for money and so much easier than re grouting. Dries quicker. Great coverage. Highly recommend. ## Features - Contains a mixture of 5-Chlor-2-methyl-2H-isothiazol-3-on und 2-Methyl-2H-isothiazol-3-on (3:1) (CIT/MIT).

If the tip falls out do not worry, simply put it back in and keep working. **Q: Do I need to press down hard while moving the pen along the grout lines?** A: 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. **Q: The colour of the pen cap is not exactly the colour I want** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best grout pens around! *by L***Y on 24 May 2026* Best grout pens around!

But would recommend as once it’s on it looks great and lasts years ## Frequently Bought Together - Grout Pen Black Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Narrow 5mm, 2 Pack with Extra Tips (7mL) - Black - Grout Pen White Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - White, Narrow 5mm Tip (7mL) - Grout Pen White Tile Grout Paint Marker Replacement Tips: 5 Pack of Narrow 5mm - Waterproof Grout Paint Pen, Grout Colorant and Sealer Pen to Renew, Restore and Refresh Tile Grout --- ## 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.ph/products/380310739-twin-pack-black-grout-pen-designed-for-restoring-tile-grout](https://www.desertcart.ph/products/380310739-twin-pack-black-grout-pen-designed-for-restoring-tile-grout) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-09-20*
