Customer Reviews for Custom Building Products Polyblend #09 Natural Gray 8 oz. Grout Renew Colorant

I decided to try this product on my darkish grout, testing it in a closet in case it was a mistake...it was not. Following the hints from other reviews I trimmed an old toothbrush narrower so it was just under the width of the grout line and put a squeeze bottle top onto the product bottle. I have glazed tile with a recitified edge and sanded grout. It went on easily and I used the brush to scrub the product against the edges of the tile ensuring full coverage, wiping off any overage. I may have applied it a bit too lightly but apparent color variation seems to fade as the product fully dries; I will adjust if necessary. I occasionally worked too large of an area before going back to wipe overage. The product had already dried but on a glazed tile, at least, it seems to scrape right off and I will use a scotch bright pad to remove any stubborn spots. It also did a nice job masking some fine chips in tile glaze which was a pleasant surprise and I will be sure use it on some other chips and cracks. The completed floor now would not be my first choice were I totally redoing the place but compared to before....it is wonderful!!

This product came recommended to me by a family member and the white grout on our bathroom floor looks wonderful! I had to adjust the instructions a bit because these I was dealing with a white mosaic hexagonal tiles with black square tiles as part of the pattern, but I just painted the smaller grout lines that had become dingy and uncleanable over the years with a paint brush. I also could not immediately wipe up the overpaint with a wet cloth as this was, as I said, a mosaic tile, but I cleaned with acetone and the floor looks lovely! I now plan on redoing the grout with my slate flooring that has become stained over the many years, and that application I expect to be much easier.

This product produced a dramatic difference in my floors. It was tedious to apply but covered old grout well and made it look new again. I applied with an artist brush. Get an assortment and see what works best. It dries so fast you really don't want to have to wipe it off the tile. It took a long time to apply but it was worth it. I used only 2 bottles for 600 sf of tile. It seems like it may last a while but even if it only last two years and I have to reapply, it is worth the time. It made the floor look brand new.

was easy to to apply, used a toothbrush so not to waist any, good coverage used half bottle for a 20 by 15 room, left side done rt side not.

So easy a two year old can do it (but really). I had a damp wash rag with me to wipe as i went. As long as you dont put pressure on the grout, it won’t completey wash off as someone else’s review mentioned. It does look a little more translucent when wet but it’s perfect when it dries! I love this product

I am so happy with this product. Antique white covered black grout without any primer products. It dries incredibly faston the grout and removed easily from the tile while still wet. Saved us thousands on a new tile job. I dis a little every night when the babies were asleep. 10 hours of work. I used a doggy toothbrush( great angle) and a damp paper towel for the excess.

Used polyblend grout in the color Bone when my tiles were installed and the installer never sealed the grout. So over time it got filthy and no matter how many products i used i could never get it to look like it did when it was new UNTIL i bought this and now my grout looks brand new.

This product was easy to use and apply. I am very pleased with the results.

Great products! I always put on 2 coats, last for years, tile looks fresh and new!

Excellent product to use on stained grout.

The colorant product itself was quite effective, and relatively easy to use. Good results, though i had to buy several different shades to get the color i was expecting from the original Oyster Gray Polyblend grout. Unfortunately, the retail stores only stock about 8 to 10 of the 40 or so colors offered, so i had to resort to an on-line order to get what i needed. The real issue, however, was the original grout product itself. While i am not a professional, i have successfully done many tile and grout jobs, including stone, marble, slate, etc. Both times that i have used Polyblend grout in medium to dark gray colors i have been very disappointed in the finish, which dries in shades from mottled grey to white. I followed the instructions to the letter in terms of grout prep, application, drying time and removal technique, but in both cases i had to go back and artificially color the grout to get the quality and color i expected. Going on line, i've discovered that i am not alone in this experience. I have to conclude that the Polyblend product is just substandard, and like the other reviewers, i am unlikely to ever use it again.

Good stuff! I hated our kitchen floor before using this as our grout used to be dirty and discolored. I don't have a before picture but this picture is final result. Next time I will use a different color though as I used linen color and would like more of a bone color next time. When floor dried the linen color did not exactly match color on bottle. Gave it 4 stars because of this. But linen will do for now as so clean looking. We did prep the grout lines before applying tediously scraping off the old sealant on them which was a lot of work but it was well worth it as new grout stuck really really well! Would recommend.

My grout looks new

I had white grout with white subway and a gray speckled quartz counter. I wanted some contrast in the tile so I used the Grout Refresh Platninum (which is a light gray). Here are the results. It was very easy to use doing it my way. Applied with a toothbrush in small sections, immediately wiping off the tile with a damp paper towel to remove the excess. Only took an hour for the whole kitchen. The next day I sprayed window cleaner to polish the tile.

It took some real elbow grease but this little bottle of paint fixed our gross kitchen floor. This was my last attempt to DIY - I'd tried all kinds of grout cleaners, bleach, nothing worked. This did the trick. Glad we didn't have to rip out the tile.

Easy to use. Applied with toothbrush first, let dry and put on second coat with small brush. I plan on getting another color for another room.

My grout looks like brand new. I’d tried so many different ways to clean and restore. Nothing else compared.

My original grout was Canvas which must have been discontinued. I made the mistake of not sealing it when I laid the tile. I bought the Linen and Antique White and mixed equal parts - close enough. Cleaned a section, let it dry and went over with the colorant. My grout lines are not straight lines and some sections are narrower than others. I recommend using a small cheap craft paintbrush. I did 2 coats on the really dark spots (years of dirt - all of it is not coming out!). Don’t worry about getting it on the tile. I had a damp rag and would wet my finger and would lightly run my finger along tile edge to wipe it off. I then waited a couple days and went back over it with clear sealer. It looks great.

This product makes our 32 year old tile floors look like new. We have 8 inch square tiles and wide grout so the impact of clear looking grout really stands out.

This looks great in our shower, the grout on the floor was showing a little wear and fading but this compliments the tile nicely.

Want to wake up the ugly tile or stone on your home. ‘‘Tis is the product to do just that! We love how it turned dull to popping out.

It worked like a charm, I applied it on by dipping the toothbrush into the liquid verses pouring it from the bottle that gave me more control of the product.

Usually don’t write reviews but this product is great!My solution to easy job. Use white vinegar in spray bottle with grout brush to clean grout first. Then someone mentioned put cap from elmers glue on grout renew bottle. It fits perfectly. Then you can put a small bead along the grout line. Next take toothbrush and rub it in back and forth. I cut one row of bristles from each side of the toothbrush. This way there is very little that gets on the tile. If it does, take a wet sponge and wipe it off as you go. I did a living room, dining room, kitchen, nook, office, hallway, bathroom and laundry. They all look great

So tired of our dark grout but love the durability of ceramic tile. Decided to try this product after much research and I highly recommend. Yes, it is a time required amount of work, but again we love our tile look. Cleaned grout with scrub brush and dry wiped up excess moisture, then let dry. Used a toothbrush and back/ forth motion to cover probably 12 squares at a time allowing 20 minutes, then going over with a damp cloth and plastic window scraper on edges. This seemed to be the quickest way to clean along grout lines. 480 square feet took me probably 25 hours total.

Yes it is time consuming but the results are great! My sister end up finishing my floors because i wasn't able to. Due to working out of town. She loved it so much she did her own bathrooms at home. Her method of making it easier were to mask up the tile with masking tape. She spent 2 hours each day doing my den, living room, and hallway. Took her about 5 days to do it all. So get your sister or somebody else's sister, some masking tape, and let them go to work! ;-D Love how everything turned out!

This product is wonderful. I was initially skeptical this would meet my expectations; however, it covered the existing different shades of brown very well. It is rather tedious because it is necessary to wipe the excess on the tile quickly. I used a 1/4" paint brush (from Dollar General). With back problems, I was able to do a 12 square section at a time, so it took about 2 weeks to finish 2 bathrooms, the kitchen, breakfast nook, entryway, and laundry room. I also bought the same colored caulk and filled in some of the hairline cracks in the tile and it is now not noticeable unless you look really closely. My spouse could not find where I had filled in the cracks! He has commented several times how impressed he is with how great this looks now. We are both very impressed and happy with this product and would highly recommend it.

Great product! Easier to use than the others I looked at. Doesn't run, easy cleanup.

I was ready to have someone rip the old grout out (9 years old) and put new in because of how bad it looked, I tried everything to clean it up but it still looked horrible. I decided it looked bad enough and the fact that I couldn't get a contractor to call me back (tried 9 different contractors 3-5 times without response), I figured I cannot make it look worse than it is. 4 hours later it looked like I had a brand new grout floor in my shower. Because of the small squares and lots of grout lines in the shower floor, it took a lot longer than I expected but $14 and 4Hrs saved me $1,500. A few areas where I didn't get the colorant saturated needed to be touched up after a month, but has been looking good for 4 months now. The directions are easy to follow, use a cheap children's toothbrush when applying the stain/sealer. I bought another bottle because I know it won't last forever, I expect to touch up or redo the stain/seal once every other year.

This product is amazing. It takes patience to apply, but for $13, it transforms a tired looking floor to looking new again. I used a thin paintbrush to apply. It is holding up well, even with wet boots and dog paws. Highly recommend.
