Don’t use these to do the whole bathroom! Lol - lol at the people out there who use these to do the whole bathroom. That’s a waste of time and money. You don’t stain an entire wood chair with a scratch touch up pen do you? For those who haven’t done tile sealing and restoration work before, go to a tile store and ask them about the products available for this or otherwise do your research. If you have mold on the grout you’ll want to kill that first then apply a sealer. There are transparent penetrative sealers, and surface coating sealers that can be either transparent or opaque colored like these markers. There are roller wheel application bottles that are best used on horizontal surfaces like floors, and brush bottles that are best for vertical surfaces like tile walls. There are also spray-on-and-wipe products that are best for those really small tiles where the amount of grout lines is overwhelming. These markers are good for what they are which is situations where you need to do some sort of touch up for some reason. I actually got one to cover a small area where the edges of the tile are visible and an opaque white sealer is needed to get rid of the grayish tile edge. I wasn’t really expecting them to work that well but after 2 months the sealer hasn’t flaked off which is better than I expected. I do expect that eventually I’ll have some flaking or wear and will need to touch those spots up again, but so far it’s looking much more durable than I expected. I did need to use about three coats of the sealer for this unusual application to get it opaque enough to completely cover up the dingy gray tile edge. So anyway these are good for touch ups or small areas but for entire bathrooms and such just go get yourself a quart or however much you need of some appropriate products and apply them as directed with roller or brush bottles. Review: Good product - Easy to use. Good way to keep grout looking neat. ## Features - LOOK BRAND NEW: Skip scrubbing tiles and use GROUT PEN to paint and recolor your grout for a bright clean appearance - USE ANYWHERE: Ideal for the bathroom, kitchen, and any other room that has floor or ceiling tiles - LONG LASTING INK: Tackle small or large DIY projects with a pen that covers up to 100 feet of wide grout lines - ADVANCED FORMULA: Non-toxic, water-based colorant that covers grubby grout stains making it look brand new again - CAP COLOR: Use the color chart (see images) for most accurate color depiction. 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 | B006MDF3ZQ | | Best Sellers Rank | #1,289 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #3 in Tile Grout #116 in Paint & Primer | | Brand | Rainbow Chalk Markers Limited | | Brand Name | Rainbow Chalk Markers Limited | | Color | White | | Compatible Material | Grout | | Customer Reviews | 4.1 out of 5 stars 8,136 Reviews | | Global Trade Identification Number | 05899406109500 | | Included Components | (1) GROUT PEN - White - Wide 15mm Tip (20mL) | | Item Dimensions | 1.25 x 1.25 x 6.25 inches | | Item Form | GROUT 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 | | Material | Grout Paint | | Material Type | Grout Paint | | Model | GP81208 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | GP81208 | | Style | Modern | | Style Name | Modern | | Supported Standards | ASTM-D4236 | | Surface Recommendation | Tile Grout , Floor, Tub, Shower, Countertop, Backsplash, Sink, Wall, Patio | | UPC | 722480212086 | | Unit Count | 1 Count | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Rainbow Chalk Markers Limited - **Item Weight:** 79 g - **Item dimensions L x W x H:** 1.25 x 1.25 x 6.25 inches - **Material:** Grout Paint - **Style:** Modern ## Images ![Grout Pen White Tile Grout Paint Marker Restorer - Wide 15mm Tip (20ml) - Image 1](https://m.media-amazon.com/images/I/71P3+P8jk1L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this product waterproof or will it wash away if I apply it to the shower floor tiles? tia** A: Yes Grout Pen is waterproof.

It looked beautiful until I put a sealer over it. (I should have searched for "sealer" before I even bought it. :-( ) Don't waste your money. **Q: Does it work on silicone caulk?** A: Silicone caulk is not paintable so this product would likely not work on it. **Q: does it work on marble tiles grout?** A: Yes, it works on grout, but it does not last long. I would guess a white sharpie would work just as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent, but only for touch up jobs. Don’t use these to do the whole bathroom!
