NADAMOO Epoxy Grout Bright Porcelain White, Dual Tubes Waterproof Tile Grout 19oz 400ml, Restore Tile Grout Line for Shower Bathroom Wet Room Kitchen, Caulk Gun NOT Included

Initially I was intimidated at the thought of using messy unruly epoxy. In addition, the tiles in the bathrooms and showers were not even in heights or gaps because of the contractor's poor job a few years ago. For right angle corners and very uneven places, I used blue masking tape, applied the epoxy, shaped the grout lines with fingering tools, and peeled off the tape immediately. For flat and even gap locations I just applied the epoxy with the fingering tools and after 12 hrs, (24 hrs also worked) cleaned out the overflow area using a sharp scraper blade. I found using the right fingerings tool was the key. If the radius is too small, there is not enough epoxy in the grout gap, and if the the radius is too large, you cannot form sharp break lines along the top eges of the grout gap, which is essential for clean look and easy overflow removal. The epoxy worked well to give clean results. Because the package contained two dispenser tips. I was able to do the touch up work after removing the overflow, the next day.

Excellent epoxy grout. Dries hard, won't stain or discolor. Pay very close attention to set up timing. If you wait too long it will be very hard to get off the unwanted surface. Waiting for just the right time, it shaves off effortlessly. The coverage is not as much as I expected so I had to order an extra set of tubes. I installed 2 foot x 4 foot high gloss porcelain LFT's with a 1/8 inch gap, in a 3'x5'x3' alcove bath tub area, all the way to the ceiling. It took 1 and a half tubes. So, order more than you think you need. I would not recommend this for small tiles, too many grout lines. I am totaly happy with this product.

I have always used their competition "REALINN Epoxy Tile Grout Bright Porcelain White 400 ml, Dual Tube Waterproof Stain-Proof Colorant Resin Sealer Grout" but decided to use this brand and try it out after having much success with Realinn brand. I ordered 9 tubes and,I have been left with an absolute mess. Followed directions to a "t". At least 25 percent of my grount lines remain uncurred after 5 days. It is a complete mess. I had Amazon replace two of the tubes and the same thing happens. Randomly it will not cure and remains a liquid paste. And yes I extracted at least 30 inches of each new tube to be sure it is mixing in the nozzle. This brand has left me with a living nightmare of an uncured mess in random grout lines. I am furious of the inferiority of the product. I am left with a complete mess trying to remove the places where the epoxy is uncurred. It is not easy, even using alcohol. *Update* the manufacturer contacted me and offered to replace 3 tubes sent directly from the manufacturer rather than older product from the Amazon Warehouse or where it comes from. If these new tubes cure without a problem I will update my review.

Timing for excess overflow removal makes a big difference on whether it is easy or difficult to scrape off. When timed right, in my case about three hours at moderate room temperature, it comes off cleanly and easier.

Great durability. Had to use fast as hardened quick and not easy to shape. Very strong.
