MapeiUltraCare Grout Refresh, Universal Grout Colorant & Sealer, 8 oz Bottle – Easy Grout Restoration & Protection, 5220 Eggshell

Exceptional product, one of the only that actually lasts in high traffic areas like floors. It is not easy to work with - it’s basically very sticky paint, not a slurry/peanut butter consistency like actual grout. That means it will get everywhere and you’ll have a lot of scrubbing to do. The results are worth the effort though. If you’re doing large format tiles, save yourself some trouble and just mask off everything except the grout line with tape but if you’ve got lots of little tile or mosaics then skip the tape and send it. For cleanup, I found I saved a ton of time with baby wipes and mr clean magic eraser instead of just water and a sponge. Lay it down (I use a silicone caulk spatula), get it worked into the grout joints, let it sit 20 mins, give the top of the tile a gentle pass with the baby wipes to soften the dried excess and then hit it with the magic eraser. I use the grooved ones to avoid digging into the grout joints, just be careful not to press too hard and drag it out of the joints. Practice a few times before tackling a big section. If you have a porous surface like honed natural marble, it will soak into the pores. Seal the tile before applying the grout refresh!The part you really want to know is whether it lasts - my marble mosaic bathroom floor with white cementitious grout had its lines constantly turned orange from dead skin, moisture and general wear. I applied this 6+ months ago and it still looks brand new. Zero complaints and it’s the only paint style option I’ve ever used that lasts like this. It also seals the existing grout nicely and makes it less prone to collect gunk.

I am very pleased with this grout refresher. It brought our 20-year bathroom floor back to life. I ended up taping the edges of the tile to cut down on the cleanup process. It is waterproof and looks just like I regrouted. Highly recommended in place of retiling!

This stuff made my kitchen look 15 years younger! I was at the point of considering putting in a new tile floor because I could no longer get the grout remotely clean (it hadn't been sealed when we bought the house.) This is not too hard to apply - not much more work than scrubbing the grout with a toothbrush and Soft Scrub just one time. Here are a few application tricks I learned through trial and error; some are on the bottle, and some seem obvious, but if you do this it will make the job much easier:I did one area of the floor at a time, starting at one edge and doing a 2 foot wide strip across the width of the room. I'm middle-aged, with not the greatest back in the world, and it was pretty tiring. Spacing out the work over a few days made it easier for me.This one's obvious, but make sure you get the floor - especially the grout - as clean as you can before you start. I used Spic and Span and a scrub brush, and even scraped some spots with a knife if there was something really dried on there. Wait till the floor dries thoroughly before you begin.Squeeze a dab of Grout Refresh onto the grout at the far corner of the area you want to cover (but not right up next to the wall), then use a toothbrush to spread it back-and-forth along the groove. A little goes a long way, so it's better to start with a small dab. You want to avoid getting a lot of excess both on the grout, and outside the grout line - just a thin coat will do, I promise.Set a timer for 45 minutes. After 45 minutes, take a clean rag (microfiber cleaning rags work great) and wet it with lukewarm water. It should be nice and wet, but not really drippy. Starting at one corner, lightly wipe the rag back and forth over the grout lines. The product you applied to the grout will stick, but whatever you got on the smooth tile will wash loose. Rinse your cloth and keep wiping lightly until you've removed all the refresher from outside the grout lines. Be sure to wipe the tile clean, because if a flake dries 24 hours, it has to be scraped off with a knife. If you got a lot outside the lines, this step is A LOT more work. Also, if you applied the refresher too thickly, a piece applied to the grout can come off and give you an uneven result.It says to let it dry for two hours with no traffic. I had a hard time keeping my cats off it, but didn't notice that they left any marks. After a couple of hours, you can walk on it, but don't let it get wet for 24 hours.I added a picture and, as you can see, my floor looked gross. It's been a couple of months since I applied this stuff, and it still looks like the day I did it. If it gets dirty, I just wash the floor and the grout comes clean as easily as the tile did. Highly recommended!

I might have to update this later, time will tell if this stuff sticks around. We have a chalk like substance between our very uneven kitchen tiles, who put that there....no one knows, but they stink. Since we are renting, the ol' tear it out and do it the right way will simply not do. I asked, they said no. So I bought this stuff, applied it and used a razor to skim the areas where it needed a little extra help keeping on the area where the grout should be. It made clean lines, really nice, however, it dried too fast in some areas and had to be put down again since it peeled up a little. Would love to see it work on grout that is not chalky, Im sure it's great. There is nothing like a nice clean grout line.
