Mapei(Frost) - Grout Refresh - Frost- 240ml Bottle

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.

I love it. Hopefully, it will be long-lasting. It's not totally white just a shade of gray. It's perfect.

This product is awesome! We used it on our white tiled shower. Not only was it easy to use but it looks better than when it was installed by our builder 2 years ago. Highly recommend this product.

I am painting my fireplace which is ceramic tile and the refresh has definitely helped with updating the appearance. Will use again for other projects.

White tile, white grout...of course it's a different shade which is fine when doing all the grout, not great when it gets on the tile. Difficult to clean off once dried (which is good if only on grout, not great when on tile). So, apply carefully, wipe up quickly and follow directions carefully. Plan for 24hr set time!!!Just applied, will not know how well stands up as we are refreshing the bathroom floor to list our home to move.
