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

Used this to brighten the grout lines on Terra cotta tile in my sunroom that had become dull and gray over the years. It did a beautiful job and was easy to apply but a bit tedious because of all the grout lines. Definitely recommend this product.

I used this on my shower grout and it turned out great! Easy to use and is holding up well. It really spruced up my bathroom.

I liked how easy it was to apply. It looks good. Now I'll wait to see how it stands up.I do need to order another. It does not go as far as I thought that it would.

works well, but only covers very small area. For a small bathroom I needed 4 of the grout pens. Would be better off buying the 125 ml. small can and using a small brush!

I used this to refresh a few faded grout lines around my tub, and it delivered clean coverage without mess. The narrow tip helps with precision, especially along vertical tile seams, and the white tone blends well with modern light-gray tile. Would recommend using masking tape so that the paint doesn't "bleed" onto your tile/porcelain.You’ll need to shake it thoroughly before each use and let it dry between strokes, but for surface-level restoration, it works exactly as advertised.— Curated by Jaded John | #OrderlyCleanDesign

Works like a charm. Floor had been scrubbed clean but dirt had stained the grout. This little pen had it looking like new in no time. Recommend to anyone for a quick way to make your tile floor look like new.

Customer service is responsive and corrected issueWas looking just to touch up a few buying of tile grout. The pen does not contain a lot and does not last very long but if you’re only looking to do a little, it will do the job. Wish it contained more does tend to wash off even though it claims it’s waterproof.

This is one of those products that has a lot of upsides but several downsides. To preface, I have a roughly 20-square-foot white tile floor in my apartment bathroom. When I moved in, the grout was very discolored and made the tile look dirty. I was extremely skeptical about this product, but it was a reasonably priced solution and a top seller on Amazon, so I gave it a shot.I followed the very simple directions on the pen (clean floors, remove cap, shake pen, use), and was initially amazed by the results. My nearly gray tile grout was being transformed back to white. Although, after I got through about 6 square-feet of tile, the pen tip started to fall apart. Was it still usable? Yes. Did it hinder the quality of the paint job? Also yes.Additionally, the paint ran out much quicker than expected. I was able to get a single coat on the entire tile floor, but the 60 meters of coverage they claim is a little far fetched.Nonetheless, my tile floors look good. A couple tips (no pun intended): get two pens because the coverage is less than advertised, apply 2 coats, REALLY clean the floors before you start (I didn’t deep clean nearly enough and the grime made the paint job much harder), consider another solution unless you have white tile as well (I feel as if this pen would not be great if you needed to be precise), and don’t push as hard on the tip to increase the pen’s longevity.Hope this helps! Still a good product, just a couple things to keep in mind before you buy.
