MAPEI UltraCare Grout Refresh, Universal Grout Colorant & Sealer, 8 oz Bottle – Easy Grout Restoration & Protection, 5010 Black

loved this product done the job, exact color match, easy to apply with a small tooth brush.

I don't usually leave reviews but this product is FANTASTIC! My grout is dark brown which I love but after cleaning my tiles with an acidic cleaner the grout lost some of itself to deep color & some areas were very light. So here's a great hint..I thought it looked too much like "paint" when applied as directed, so after I painted it on (with a soft toothbrush) I immediately wiped down the grout w/ an old, damp T-shirt. It looks softer now, the color is the same just not as "paint-like." This also allowed me to clean the tile at the same time so no having to go back over later. There are so many colors & they are true to what you get.

Last owner installed this back splash with what appears to be some type of concrete.It was brown and dark and didn't look nice with the color tile in my opinion. I was worried I would have to go darker so when I read the reviews here and saw how it was covering dark grout lines I figured it was worth a shot.Purchased in the frost color which looked like a light gray. Cleaned everything really good two days prior so it would have time to dry.Directions give two options for applying depending on the tile. One is a wet method where you let it sit for a few minutes and mist with water them wipe, second was dry method where you wipe immediately with a dry paper towel or microfiber cloth.I started with the dry method and after about five minutes realized my grout was absorbing the color so fast I could wipe with a wet microfiber without it smearing on the tiles and without it pulling from the grout.Picture 2 shows it after two coats, still drying. I used a stiff small stencil brush for application. I know people complained about the nozzle clogging. They probably shouldn't be attempting home improvements as the top unscrews and you have to unscrew said top to remove the seal. I did not use the nozzle I just dipped the brush in and carried on.First pass the color looked bright white, I used the stencil brush to really push it into all the nooks and crannies. Wiping with a wet cloth as I was going. I didn't have to worry about being neat, it wiped off extremely easy from my tile. By the time I wrapped around the entire back splash, about 20 minutes, the starting point had absorbed enough for a second coating.It dried true to color, covered the brown entirely and changed the entire look of the kitchen. All this completed in about 40 minutes, granted we have large rectangular tiles and there was not as much grout lines to work over so timing will vary.I used maybe 1/4 of the bottle.I could not recommend this product more highly. It did exactly what it advertised it would, it was extremely easy and super cost effective. Super happy with the end results.

Overall, I'm pleased with how easily the paint applied. Our house has its original 1994 tile, and the grout had turned a disgusting color from years of neglect. Since we purchased our home a couple years ago, I couldn't decide whether to gut the bathroom or cover the tile; but when I came across the paint, I thought it could be a good temporary and low budget fix. Yet to be seen on how well it will hold up with cleaning.Pros: coverage seems effective; Rain is a nice blue-grey that's pleasing to the eye; low odor; dries quicklyCons: the nib (cap) doesn't have a way to close it and dries clogged if you don't plan to use it all at once; it can be messy, so be patient with applying and cleaning up the lines; there's no way to get the lines exactly pristine, especially if the grout is close to the same level as the tile

The color I used was Biscuit and you can't go wrong with it since it's very neutral. It's a little grayish white, but matched the tile beautifully. I just remodeled my bathroom and the grout was the ugly dark color shown in the photo. I have to caulk that and waiting for it to cure so I can add some white caulk with the color and apply to that corner. I scrubbed my tile first with a bleach based bathroom cleaner and gave it an hour to dry.This product was easy to apply using a toothbrush which I cut the higher bristles down with scissors. Give the bottle a good shake. I found using less product is better. I applied a very thin line around 4" long to each side of the tile and worked it in with the toothbrush and it doesn't hurt to have a spare one handy. DON'T use a paint brush for better results. It's ok if you make a mess because you can easily wipe off the excess with a damp cloth towel in 20-25 minutes, but mist the area with a spray bottle first. If you wait longer than 25 minutes it will be harder to get off so I suggest working in sections if you have a larger area. Don't try to wipe it up as you go along because you will make more work for yourself since it needs to dry a little. Don't use paper towels on the whole floor to clean up excess because you will need a whole roll. I did my whole floor and shower in less than 2 hours. The color is beautiful and it completed my remodel. Just so you can understand how easy this is to use, I'm a senior female and have some physical disabilities and did this with very little difficulty.

Works perfectly!!!!!

Visited their website to check the Avalanche color before ordering. Looks to be a soft white or light biscuit. I received mine today and it's not close to their color chart. Instead avalanche is bright white. Disappointed and wasted my money. Update: I decided to try it on an inconspicuous grout line near the toilet. It seems acceptable if I apply it as a very thin layer and the old grout color is slightly visible.

This product was super easy to use. I used the light almond color, did two coats and added 2 coats of 511 impregnator to helps seal it from water and stains since it’s such a light color. Time will tell how it holds up. I will update if possible.
