Customer Reviews for Custom Building Products Polyblend #380 Haystack 8 oz. Grout Renew Colorant

I bought this product in the hopes of restoring the grout in a 1920s bathroom tile floor. It didn't work for this purpose. The grout lines were too narrow and shallow to apply the Grout Renew. I suspect the grout also may have been too worn or perhaps wasn't grout at all but something else they used back in the day. However, the grout renew worked fine on our more contemporary kitchen floors, which is why I'm giving this 5 stars. The problem was with our vintage floors and not the product itself.

This product is awesome. My kitchen floor never looked better before.

Easy to use. Take your time and work in small areas for best results. Used tooth brush and cotton swabs for great coverage.

Granted this is quite labor intensive, but I am so happy with the results. I feel like I have a brand new floor!

How you apply Grout Renew and the time you take in doing so really seems to makes a difference. I used an artists paint brush, and due to irregularities in how my tiles were set 25+ years ago, painted one tile at a time and wiped up mistakes as I went. (The paint and wipe off with big strokes from a rag method didn't work for me because it took off the paint on the grout too.) I suggest working left to right and top to bottom if working on a wall/ tub surround so that you avoid touching what you've already done. It took several hours to do my tub surround, but I am pleased with the results. I am also following the recommended wait time of 72 hours before getting the walls wet in hopes that it will help with the longevity of the results since it took so much time. This was a low cost way to freshen up our tired looking bathtub when replacing the old tile wasn't a feasible option.

So easy to restore the grout color! Phosphorescence makes the grout look dirty no matter how much you clean the floor. This project is actually fun to do! Wish I found out about this product years ago.

Incredibly difficult to apply and remove from tile. I estimate treating 80 square feet of subway tile at my current rate to take about 40 hours and even then there’s still remnants and specks which need to be scratched off with your fingernail. Absolute garbage.

Pros: very easy, very inexpensive, looks great Cons: hard to determine correct color, samples pics/labels aren't exact, only way to know is to sample on floor - which could get costly. 5 hour project completely transformed and updated grout. Very easy to apply - I used the blue tape suggestion and an artist brush - available in a small assorted set in the paintbrush section at Home Depot. Worked right from the bottle - no extra container needed. Cleans very easy with water, and doesn't run or bleed through blue tape, so clean-up is really easy. Did the whole room and still have about a quarter bottle left!

These are 2 different clients houses I've used the product at. Amazing transformations. The one house had plain color tiles and it looks like we put new floors in now. The other house the colors in the tile really pop now.

Spent forever scrubbing the grout with different cleaners meant for grout and could NOT get the stains out. Spent several hours painting this stuff on...but it was worth it! Amazing difference.

I used bright white. It says a bottle does 80 sq feet. My lanai is about 160 sq ft with 18 inch tiles. I still have some product left in the bottle. Looks like new grout. Hope it washes and wears well.

Very old floor that rightfully should have been ripped up. With some elbow grease and a toothbrush and less than two hours, my floor looks brand new!!

After thoroughly cleaning the old grout, I put a layer of Custom Building Projects Custom Warm Gray Aquamix Grout Colorant on the grout but decided it was the wrong color so I purchased this Polyblend Snow White color and layered it on top of the Aquamix. Since it's from the same manufacturer, it went on perfectly. I used a paint brush and cleaned the tile along the way. It did take about 6 days to do two coats but it now looks awesome. I feel like I have a new floor! The color is great and is holding well and I'm very happy with it.

Let me start off by mentioning that our house was built six months ago. We have a little over two thousand sq ft of tile we needed to recolor because we chose white grout and we have four dogs. We have ceramic glazed tile and the best way i found to do this was apply it with a toothbrush and let it dry for three days before going over it with a scouring pad to remove it from the tile. Doing it in small sections and wiping it away would just take too long for my liking. It comes off easily on the glazed tile

Extremely happy I found this product. It takes a lot of work and patience but definitely worth it.

Revived my bathroom. Tried everything to get my grout clean, nothing worked. This will always be my go to.

Polyblend was absolutely easy to apply (with a really thin paint brush), it gave my bathroom tiles a fresh clean look. Downside painting the grout was time consuming but very easy with patience and great music to listen to while you work.

Easy to apply. Looks great. Hope it holds up and cleans well.

I have tried everything to clean or "fix up" the old tile in the bathroom of the apartment I have been renting for 5+ years. I found PolyBlend Grout Renew and the transformation is absolutely amazing!

This was my first time restaining grout. The tips written by Kim T and Kirsten definitely helped me. To them I am most grateful. I replaced the cap with an Elmer’s glue cap and that delivered a fine line of the grout. You don’t need much. I used my grandchild’s tiny watercolor brush instead of the toothbrush to smooth the grout and get it into corners. I sprayed rags with rubbing alcohol and wiped the excess off the grout and cleaned the tile with this a few minutes after applying the grout. I had the bathroom fan on and was afraid if I waited too long it would dry. I did a second and third wipe with a clean alcohol sprayed rag to make sure the tile was cleaned of any grout. I used Bone. I am so happy with the results.

THIS STUFF IS AMAZING. It completely changed the look of the bathroom in the condo we just bought. I still have over half a bottle for touch-ups--though, according to reviews, I won't need it. I've been recommending this to everyone I know. I applied it with the smallest two of these brushes (Unbranded Angled Artist Paint Brush Set (4-Piece)) and used a damp rag to wipe off the excess from the tile. I ended up doing 3 coats because the grout had been pretty dark. It took some effort to wipe my messy painting of the Grout Renew off the tile, and I was pretty lazy about wiping so I'd also wipe some off the grout when I tried to get it off the tile. Oh well. It looks so great now. I was undecided on which color and ended up just getting the only light color that my Home Depot had in stock because I was so eager to get this done! Looks so fresh now.

I used grout renew and loved the ease of use. I followed the recommendation of swapping out the cover with the Elmer's glue cover (easy since Elmer's glue was selling for $.50 due to back to school sales). Using the glue tip made application easy because I squirted a couple drops along the grout line and then painted in using a toothbrush. I avoided major clean up by taping off my grout lines. That part was tedious but worth it because there was no clean up involved at the end. My first attempt I used the color Bone. Bone appeared to match the grout color in the areas that were not stained by dirt. However Bone was way too light and I didn't like it at all. So my second attempt I used Haystack. Much better and the look I was going for. Too bad that the color example on the bottle is way off compared to the color in the bottle. I wasted a couple of hours with that mistake.

I’m going to save you a lot of time. This product is awesome! But...when you apply it to the thin white lines on your grout you WILL get it on the tiles. Put a coat on, let it dry for about 30 min (it doesn’t take long), then wipe your tile with a sponge with a little rubbing alcohol on it. The sealer comes off the tile but not the grout. Then revisit with the same steps.

We used the Cape Gray color. It looks great and was easy to apply. Some spots needed a second coat, especially places where the tiles were slightly uneven. I would recommend this product to anyone trying to cover up their unsightly formerly white, stained grout. It’s so much easier to paint your grout than replace it!

I cleaned my tiles and grout using a steam cleaner. Let dry thoroughly. Used a small paper plate, quarter sized amount of product, a clorox wipe, and a dollar store kid sized toothbrush (with side bristles cut) to apply. I cut in near the woodwork with a cheapie kids craft paintbrush

We used the color chateau. It looks great. So darn pleased to not have to be scrubbing grout! It takes forever and is labor intensive, but the payoff is worth it!

I can't believe I waited this long to buy this and refinish our tile floor grout! It's super simple and COMPLETELY transformed our floors! They look brand new and the house looks extra clean! Yay! Don't hesitate to take on this project, it's well worth $13.

This product worked well for me it’s just long and tedious. Keep you a spray bottle with soap and water a few Terry cloth towels and your toothbrush and have at it!! Mine turned out great. I did four rooms. Took one bottle.

Grout looks much better now and will stay that way.

We recently installed white subway tile and after grouting, didn’t like the color of the grout. I got a bottle of this stuff in Charcoal. Bad idea. It now looks like I tried to color the grout with a sharpie. Charcoal is BLACK. And application is a long process trying to get it on the grout and off of the tile. It’s a hassle and now I have to tear out the grout to fix it.
