Review: Works well, easy to apply. - The product is easy to apply and seems to hold up well. Haven't had a real test yet with colored liquid but I've had it on for a couple weeks and the grout still looks clean. It does dry fairly quickly and the two coats is a good idea. I used it on my floor with quarter inch grout lines. I used a foam brush typically used for crafts and it worked well. Just need to tilt it and let it drain out for a few seconds after dipping the end in the sealer.
