GRT SLR, Grout Sealer, 6 oz.

Good quality, durable, easy application, time-saving, long-lasting, stain-resistant, dries quickly, shipped fast, and reasonably priced.

Easy to use. Product worked as intended

Did a good job sealing the grout. Don't peal off the seal inside. Poke a hole in the seal the grout seal is very thin liquid and flows freely so if you peal off the seal under the cap you will have a mess.

Was having issues with shower grout discoloring. Used the sealer and made a big difference! Easy to apply.

Worked great on my recent tiling project. Used small artist brush instead of built in dispenser for better application control. Very happy with results.

I wanted to see how this grout sealant would perform in my shower, which has two different types of grout—one very porous and one that appears partially sealed already. I followed the instructions exactly, applied three coats, and allowed it to cure for a full week before exposing it to water. After testing, I was surprised to see absolutely no improvement in water resistance. I even waited a few more days hoping it might improve, but there was still no change. This product might as well have been water—it did nothing to seal the grout in my shower. The only positive is that the label claims coverage of about 75 linear feet, but I found it closer to 150 with two coats. Unfortunately, that extra coverage doesn’t matter much when the product doesn’t work. This is easily the most ineffective grout sealant I’ve ever used.

Not sure how well this works yet. Recently used this on shower grout. Will see if it does the job. The top has a brush on it that once you use it, you can’t get the top back on. It was also difficult to use when you needed to go up the side of the shower and too much product rushed out when you pointed it down. However, if it works at keeping mildew at bay it would be worth it. So far not impressed with how to apply this product.

Great product
