MAPEI UltraCare Grout Refresh, Universal Grout Colorant & Sealer, 8 oz Bottle – Easy Grout Restoration & Protection, 5042 Mocha

Take it from someone who has used to steam clean light grey grout every 6 months…. This is must buy!!! Picture taken is a high traffic area by doggy door. I watched a YouTube video to apply ( do not use back instructions of bottle) first buy one bottle to see if you like color. Match it to color of tile. I wouldn’t recommend a drastic color from current grout. I ended up liking Timberwolf the best. To apply- place grout colorant in small glass bowl and paint grout with small paint brush. I used my kids artwork paint brush (dollar store). It dries quick and bottle goes very far if applied quickly. I would do 4x4 section at a time. To clean up sides - add hot water in a second bowl and use a microfiber cloth and gently scrub sides of tile for smooth lines. I first did my laundry room and didn’t mop for 2 weeks to allow the sealant/paint cure fully. It’s now been 3 months and I decided to do rest of house. Couldn’t be happier with the results!

This is amazing stuff, I love this brand. tried different brands, but this is the best. My house is 20 years old, with tile floors. I wanted to replace the tile floors about 1200 feet of tile. Instead I repainted the grout see how it would look. The tiles look brand new. The floor looks bright, clean and appealing II is esay to apply, took me 4 weeks to complete the whole house. Works so well, I have now done my 2 daughters house too.

Works great, my tile looks better than when it was installed. Uniform coverage and goes a long way. I have 17 x 17 tile with 1/4 inch grout and 3 bottles covered about 1800 sq ft. In doing this by myself I got down the best technique towards the end. Put down no more than a pencil lead width and spread with a toothbrush removed from tile surface with paper towels. Use lots of paper towels and good luck

Coverage was high quality but it does leave a different grout texture than typical. Goes on and has a dried paint consistency.

Absolutely love the end result, I took the time to tape off my entire kitchen and cleaned the grout with hot water & scrub brush the night before, let that dry overnight & painted on the product with a small artist brush. I couldn’t be happier. I have since cleaned the floor & this product wipes clean every time! Also one bottle did my entire huge kitchen.

Pictures are of a navy blue glass subway tile wall in a shower that was part of a bathroom renovation. The “contractor” made a right mess of the job. One of the issues was this light gray, almost mortar colored grout that was supposed to be almost black.I read a bunch of these reviews for application tips.I ultimately used a Filbert style art brush to paint on the seams and let it dry while I completed the entire wall, which took a couple of hours.The overage came off the glass tiles easily with a damp microfiber towel and the results were excellent. The color did not come off the grout as this is, essentially, a colored sealer which was totally cured.The color is Night Sky.

Update: a few months in and all the grout paint is coming off where the water stream from the shower head hits the tile. I followed the instructions to the T. I cannot recommend this product. All my time wasted. We had our shower re-tiled 2 years ago, so our grout was in good condition. The problem was that I chose the grout color in a rush because the color I wanted was not in stock. It was dark brown. We used the same dark brown in our kitchen, which I like because we have an industrial look in there. In the bathroom, I wanted more of a "spa" feel, and the dark brown was not working for me. I considered having the dark brown removed and then replaced with the light gray that I originally wanted. I couldn't find anyone that would do it. I did some research and came across this product on Youtube. I watched several videos and read the reviews to avoid my own learning curve. It is time consuming, but if you follow the instructions of those who have done it, it is not difficult. My grout did not have a sealer on it, so the Grout Refresh was a good choice. I began using a tooth brush, but then switched to a stiff, wide artist's brush, which I like better. I used the "dry" method of covering the grout, letting it dry, then wiping the tile with a MOIST cloth and using an old credit card to scrape the excess off the tile. The concept is similar to scraping dried paint off of glass. If you don't let it dry long enough, you can remove some of the color on the grout joints. I abolutely love my grout now! I was able to get the look I wanted all along. My concern is how will it hold up to chemicals and scrubbing when I clean our shower in the future. I've contacted the company to inquire about this. At this point, I hight recommend, but follow the guidelines before and during application.

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.
