Is this real grout or just a silicone?

PentaUSA is a real ready mixed sanded grout that fills, bonds, and hardens into structural grout. Unlike grout pens that only paint the surface, this formula creates a permanent waterproof repair.

What is the drying time?

Our grout dries in an hour. For wet rooms, we recommend waiting 24 hours before exposing it to water.

Do I need to remove my old grout?

You do not need to remove your old grout. You can apply it directly over the existing grout. However, removing loose or damaged grout with our grout removal tool will help achieve better results.

How is this different from grout pens?

Unlike grout marker pens that simply paint over existing grout and offer only a temporary cosmetic fix, our ready mixed grout works as real grout. Once cured, it forms a durable, long lasting grout.

How much can this ready mixed grout fill?

Enough for a full bathroom floor and shower. A single 250 g tube of PentaUSA grout covers approximately 16 square metres of 12 x 12-inch tiles. Coverage may vary depending on the size of your tiles and the depth of the grout lines.

Buy this product!!

Excellent product!! Absolutely recommend! In a new build house, grout work was pretty sloppy and grout can be very hard work to keep clean. It has made my shower look brand new, very simple instructions, VERY easy to use. Even removable is easy, you have a good 2/3 hours to scrape off any excess. I will be repurchasing this product in the future. I also purchased the HG grout protect for extra help and sealant.

Meh

It works but is massively overpriced and messy to apply. Buy a cheap tube of grout and a gun to apply for half the price with twice the quantity.

Does Exactly What It Promises

We used the PentaUSA Grout Reviver on our bathroom floor, and it worked perfectly. The product is easy to apply, dries quickly, and does a great job of refreshing and filling the grout. The bathroom looks much cleaner and brighter now, and the tiles have a renewed look. It does exactly what it promises, and the fast-drying formula is a real time-saver. The tube design makes it easy to control the amount you use, so there’s no mess or waste. We’re very happy with the results and would definitely buy this again—most likely for other rooms that need a similar touch-up. If you’re looking for a quick and effective way to revive your grout, this product is a great choice. Highly recommended.

Good 👍

Easy to use and effective for small repairs and fillings. I had some tiny holes and missing parts on the grout and this was great filling them. It “sticks” well over the grout. I also risked changing my floor grout colour by covering it with a thin layer of the gray one and it worked very well! It dries as grout and application is so convenient. I’m happy I came across this product.
