Roller won't get liquid into the grout, it may only works properly or somehow properly on floors but not on walls..

Not easy at all to work with, truly a waste of money.

Much easier to roll the grout sealer than using brush. Saved time with wiping sealer off of tiles and save money used a lot less sealer.

Great for sealing my tiles

Easy to use, nice flow of product from the rolling tip no dripping of products!

roller disintegrated within 20 min of using on 6x6in tile floor.

not suitable for walls

Not recommended for walls. You will get drips where you don't want, and you have to hold it at angles, so it's not effective. They should update their description to say it only works well for floors. I ended up using a small brush instead.

Very hard to squeeze, clogs all the time, does not cover 1/4 “gaps with thicker wheel

Would be great for flooring, but I ended up just using a foam brush to apply the sealer to the backsplash.

Not doing what is supposed to do. A brush works 10 times better

not good value

The applicator works fin but there are other factors that don't make it worthwhile

I have stained Grout with this tool, several times and perfect lines, just the right amount of product comes out.

This worked ok. Didn’t do well on diagonals or wider areas of grout. Ended up using a foam brush which worked way better.

Applicator worked as intended. Sealer effectiveness yet to be determined.

Worked great and cut the time it took to seal my grout lines

First time using one and it was great

The grout sealer applicator didn't last 1/4 of the job. The wheel rubber came off. I had to used a 1/4 paint brush to do the job. A waste of time and money. Lucky for me i had a small artist paintbrush.

Easiest way to seal grout

I don't know why Home Depot and other stores do not sell these anymore. It is the best, easiest way to seal grout. Spray cans get sealer all over your tile, so you have to scrub off all of the tiles. This bottle keeps the sealer right where you actually want it and there is no mess to clean up afterwards. The only thing the spray is good for is shower ceilings.

None

Good

This seems to have solved my problem of water penetrating the grout. I used three coats for good measure.
