Grout Pen Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Narrow 5mm, 2 Pack with Extra Tips (7mL) - Winter Grey

Works great, just take your time & have a damp cloth to wipe excess. I let it set up for 8 hrs, but the only reason was because I then put a sealer on all the grout. I did this in my fully tiled walk in shower that was 6 yrs. old. It is now totally refreshed & looks brand new again. These grout pens are great.

The media could not be loaded. Wow, where do I even begin?!I was noticing how often I was having to scrub my shower (daily) crazy hard scrubbing/deep cleaning and nothing was working.Lesson one: stay up on sealing your tile every 6-12m, this is so important so you won’t end up in the mess that I had to deal with. We moved in to this house 5 years ago and I only sealed the tile once when I first moved in. Essentially I’m four years overdue for sealing the tile. When you get behind on sealing your tile it allows water to penetrate the grout and mold/mildew begin to slowly spread despite cleaning. I did not want to pay to get this fixed because it wasn’t super bad, so I decided to tackle it myself. This is what I did…First, I applied cleaning g vinegar (30% or more) and let this soak for 3 plus hours (it’s so so so strong so please ventilate). I did multiple round of this for days. Please note, bleach does not kill mold spores! It looks like it will, but it’s not. Vinegar or hydrogen peroxide is much better.Second, I stripped the caulking with a simple box cutter.Third, I used these grout pens (winter gray color, which is very light almost white, but with a hint of cool tone) I bought 6 packs. I love the color, it’s so clean and fresh looking. I used one coat and applied in the same direction shaking the pen frequently and changing the tips when necessary. The pens were great, but seem to run out quick, so I had to buy several packs for my average size shower. They were easier to use on the floor (I will use a tube style next time for the walls). These pens were amazing though for the little floor mosaic tiles. Gently wipe with a damp rag to remove any excess grout from your tiles.Fourth, I re-caulked the shower with mold resistant shower caulk.Fifth, I sealed the shower 3 times…& put this in my calendar every six months!I am just a mom with no home repair experience, but I am extremely happy with the results and researched the process to try and do everything right!I hope this helps your shower looked like mine did :)These grout pens were amazing especially for home diy projects!

They work well, they brightened up my 2-year-old white shower stall floor tile grout. It looks brand new now (I have an issue with a lot of iron in my water so lots of orange stains that cleaning no longer was enough). My shower is about 10.6 sqft with hexagonal 1.5" tiles and about 200 ft of 1/8" grout lines. However, as others have noted, on cementitious grout, the nibs/tips wear out very quickly. I used all 4 supplied with the 2 pens then had to stop, order 5 more nibs overnight Amazon delivery at extra shipping cost to complete the job without having the shower unusable for too long. I used 8 nibs total and 1.5 (?) pens. Advice? Buy extra nibs if you're working with cementitious grout when you buy the pens. I really think they should stress this in the product description. Would have saved me time and money.

I have a huge kitchen, hearth room, hall, 1/2 bath and laundry room that have light colored tile floors. The 20 year old grout was originally light, but over time had turned dark. I included a before/after pictures so you can see the difference. I decided I would paint over the grout and I chose this product because it got the best reviews. I hand painted every inch of the grout and used 9 paint pens in the process. I worked 2-3 hours at a time and finished the project in 3 days (Appx. 10 hours of work total). I chose the cream color, which was perfect. The pen works great and comes with extra tips so when you wear it down you can replace it. I have rough grout, so the tip of the pen frayed pretty quickly, but it worked even better for me that way. It's easy to apply and looks great! I highly recommend this product.

We are deep cleaning the bathrooms and main area on our 30 year old house. The grout was never sealed! We bought the house 8 years ago and things needed repair and cleaning. These pens work great! All three bathrooms have black tile and grout. We went over ever grout line. The faded grout looks brand new. My recommendation, get the pack with 2 pens, you get extra ink nibs. They will wear out before you run out of paint. And, if you are heavy handed like my husband, wear them down even faster. Be prepared to shake the pens a lot to keep the paint flowing. We also went back in with sealer after the paint dried for extra protection. I couldn't imagine what we would have paid to hire someone to come in and do grout restoration. Between the pens, sealer and a few supplies we spent $50 on 3 bathrooms, kitchen, living room dining room and family room. I really recommend this product.

I live in an older apartment building and the shower grout needed a touch up and the product did the best it could, however, you have to use so much of it to get the job done. I had to use both pens and both replacement heads because of how hard it is to get the product out after the first few swipes. I would browse around for a different product before buying this one given the price point.

Great QualityEasy to use and apply to groutI changed my white dirty stained grout to grey and loved the outcome. Dried very quickly, very easy to clean off porcelain tile when it leak while applying.One thing I wish that the tip of the pen can with more head replacements. They do wear out and you have to change it or your paint will come out too thick.

Works as advertised. Easy to use. Color appears lighter than pen cap but cover darker old grout.
