Review: Fab product but buy extra nibs - These are great for reviving fading/mucky grout, either in the kitchen or bathroom, and so easy and quick to use - great for the price. I recently painted tiles in our kitchen in quite a dark colour and was impressed by how well the grout pen went over the paint for that too + it only took one coat. There’s loads of liquid in the pen but the nibs can wear out quite quickly, especially if your grout is a bit course or the lines aren’t too flush with the tiles. You can turn the nibs around so get use out of both ends but I found that the second end would wear down (and become tricky to use) whilst there was still liquid left, so glad I got some replacement nibs which has made the pens last much longer. Review: Works well once you get into rythem of using it - To start, your grout has to be in a decent shape to start with. Its not going to magically fill in all the holes and cracks in old grout and magic them smooth. So cut out old grout and redo as this is not going to solve your issues. If grout is flat, no holes or large cracks, decent when first installed then this will work magically over it. Certainly revived the old grout to my tiles. The pen applicator is easy to use but you got to get it right, dont drag it too hard or the nib disintegrates in no time. Lesson learned, pen no.2 squashed nib few times to get the flow and lightly dragged in one direction in constant line and it worked well, dont treat it as a felt pen colouring or you will get squidgy nib. Take a normal felt pen, look for a brick wall and in the joint drag the pen from one end to the other end of the wall and thats what you get, grout is going to have same destroying effect on the nib. Be patient take your time and it works great ## Features - Contains 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-2 H-isothiazol-3-one and benzisothiazolone. May produce an allergic reaction. - Restores Tile Grout and leaves them looking clean and protected - SEALED GROUT: The white grout pen for tile may not bond to recently sealed grout. Test the grout with a few drops of water. If the grout does not absorb the water within a few minutes then the grout was likely sealed - Covers up to 60 meters of 2mm width grout lines - ADVANCED FORMULA: Non-toxic, water-based tile repair colorant that covers grubby grout stains making it look brand new again - GROUT REPAIR ANYWHERE: Ideal for the bathroom, kitchen, and any other room that has floor or ceiling tiles - LOOK BRAND NEW: Skip scrubbing tiles and use Grout Pen to paint and recolor your grout for a bright clean appearance - CAP COLOUR: Use the colour chart (see images) for most accurate colour depiction. Pen cap represents each pen's color but is not expected to be the exact shade, do a small test area first - TIP MAY WEAR DOWN: The grout whitener 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 gently pump the tip (20-30 times) until fully saturated ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08S7NNYT4 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 3,944 in DIY & Tools ( See Top 100 in DIY & Tools ) 24 in Tile Grout | | Colour | White | | Customer Reviews | 4.3 4.3 out of 5 stars (1,745) | | Date First Available | 13 Dec. 2011 | | Included components | 3 Grout Pens | | Item Package Quantity | 1 | | Item Weight | 75 g | | Item model number | GP81108/3 | | Item thickness | 1.4 Centimetres | | Manufacturer | Rainbow Chalk Markers Ltd | | Material | Water Based | | Number of Pieces | 3 | | Part number | GP81108/3 | | Product Dimensions | 9.5 x 1.4 x 19 cm; 75 g | | Size | 7ml | | Special Features | Waterproof | | Style | Compact | ## Product Details - **Brand:** RAINBOW CHALK MARKERS LTD - **Item dimensions L x W x H:** 9.5 x 1.4 x 19 centimetres - **Item weight:** 75 Grams - **Material:** Water Based - **Style:** Compact ## Images ![3 x White Grout Pens - Designed for Restoring Tile Grout in bathrooms & Kitchens - Image 1](https://m.media-amazon.com/images/I/81Ru83eINdL.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. 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 ### ⭐⭐⭐⭐⭐ Fab product but buy extra nibs *by A***R on 13 February 2023* These are great for reviving fading/mucky grout, either in the kitchen or bathroom, and so easy and quick to use - great for the price.
