Does not repell water
I recoated my marble counter top. I put on 2 coats. Water goes right through. Does not bead up on the surface. I formally used 511 porus plus and it worked amazingly great. Im returning 511 H2O to home depot

    I was generally pleased with it’s ability to repel water. But, the 511 Impregnator Sealant is a better product. It’s not water-based, and it costs more, but it does a better job repelling water. The company product rep told me the opposite. I have half of my slate sealed, with one, and half the other, so I will watch it over time to see how it holds up, as it needs to be resealed frequently to protect the fragile nature of slate.

    We appreciate your honest feedback regarding your experience with the Rust-Oleum Miracle Sealants Water-Based Sealer. Both products repel water; however, the application results are dependent a little more on use case. Our goal is to hear that your end result is satisfactory, and we thank you for reaching to keep us posted on your experience. - Rust-Oleum Product Support 1 Rustoleum

    511 H20+ Water-Base-Sealer
    Bought a new home we have granite counters and tile grouted floors. Got a recommendation to use 511 water base H20-+ sealer. I applied the sealer per instruction. When finished I was pleased with the results. No complaints now,only time will tell. PS. Have spilled thing that could have left a stain. Wiped up the spill no stain left behind!
