Grout Pen White Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pens - White, Narrow 5mm Tip (7mL)

This is a repeat order. Love this product. When your grout is dirty and nothing seems to help, this will work wonders. Easy to apply, long lasting.

I installed an expensive soft white tile (if there is such a thing) floor in the kitchen when I bought my house. At the time, it was a new product and it was beautiful--that fuzzy, warm feeling changed the first time I dropped a fork. I have been so frustrated no wanting to rip up and put down replacement tiles. The grout pen made it look new again, I am thrilled with the results!

Basically, this stuff paints your grout. It does a fantastic job for about 15 minutes - then the tip becomes frayed and the paint runs out. Would give it 5 stars if it lasted longer. See my before and after photos of my kitchen tile counter. It doesnt clean up all the dirt in the cracks but does cover most of the uglies.

The product works well.. I did feel it didn’t last as long as I thought it would.. I was working in a standard size kitchen and I have used 4 pens.. I’m not sure if this would be normal for the product or not

Applicator Tip should have a finer bevel for more precise application

Does exactly what its advertised to do but make sure you actually have WHITE grout before using it, otherwise your results will be freakishly bright. Wish they made these in other colors, like pale grey and beige...

The felt tip of the marker fell apart when applying it to my grout between the tiles in my shower. Didn’t last more than 3 minutes before it started shredding. I wasn’t applying more pressure than normal as if I was using it as a writing utensil. Waste of money and effort.

This is working nicely. I may need to reorder to get my whole bath/shower complete. I wish they offered an tip narrower than the 5 mm.

I was very nervous about using these given the mixed reviews, so hopefully this helps anyone on the fence about using them. I bought two different colors, the gray and the white. The gray definitely has a slight blue-ish cast, so if that is going to bother you use a different brand. The white is a true bright white without any ivory or yellow. Do not count on this matching your existing grout. You will not be able to just touch up a few areas. Just plan on doing the entire room. As to usage, I was pleasantly surprised by how far these went. I did the entire floor of my large master bathroom plus a little of the shower with one pen. The shower floor has small hex tile with larger grout lines so that took a little over two pens. Some tips: shake very well when first taking out of the package and any time you start working again after a pause. Depress the tip several times on to a paper plate or directly onto the grout line to get the paint flowing. Press very lightly when going over the grout. The tips lasted almost all the way to the end of my project. If the coverage starts to thin, pause and depress the tip a few more times. I would do about a 1x1 foot area, then pass over it lightly with a damp paper towel to get any overage off the tile. It is pretty forgiving and you have quite a bit of working time before it dries completely on the tile. If the tip gets too ragged you can pull it out (I used the damp paper towel) and flip it around. This was not a quick task but it went faster than I thought it would. I was worried the white would look too bright, but it just makes everything look so much cleaner. Very happy with this product!

I posted a negative review on this product and the company contacted me. They apologized for the markers and wanted to refund me. I told them I was ok with not being refunded because as bummed as I was sometimes things just happen on a production line that are out of you hands and I think thats what happened here. The next day after that they refunded the money anyways. I wanted to update my review with this information but editing the old review was not an option so I wrote this instead. The markers that were good were very impressive. The look of the shower after finishing was a complete transformation and looked beautiful. In all I believe this company to be honorable with a quality of product that is great too. Like I said, sometimes production lines can get wonky, it can happen to anyone and this company did all they could to please me.
