    Q:Will this product prevent mold growth in the grout in my shower? I can manage the mold with consistent treatment but I'd love to be able to prevent it coming back!

    Answer This Question

    A:  This is the best product I have found to seal grout but I still get a some spots spots even though I use a squgee and wipe down the walls after every shower.  I also use a strong concentrated grout cleaner called Tile and Stone Cleaner made by Miracle Sealants Company to clean grout first. You may want to try a steam cleaner first then let dry thoroughly for several days before applying the sealer

      A:  Thank you for reaching out! Yes, by sealing the grout, this will make it more difficult for mold to take root in the porous grout, preventing growth in the grout line of the tile. - Rust-Oleum Product Support 2

        A:  I can’t say. I got it to spray on grout in our entryway. There’s been no mold, but it really has protected it well from crumbling. Whether it’s this spray’s fault or the grout’s, I don’t know.

            Q:Can the 511 sealer be used on small marble mosaic tile (irregular size rounded shapes) in shower floor? 1) Will it discolor the tile? 2) Is it OK to use when some grout lines are wider than 1/2" ? (sanded grout)
            by|Jul 2, 2022

            Answer This Question

            A:  Happy to help! Rust-Oleum Miracle Sealants Spray-On Grout Sealer can be used in a shower to seal grout and will not alter the appearance, and can also be used on marble. This product can also be used on grout lines wider than 1/2"; the width of the grout line is not a factor in the application. Once the grout has completely cured, hold the spray nozzle 6" away from the grout and spray 511 Spray-On Grout Sealer along the grout line. Wait 3-5 minutes then use a clean, white terrycloth towel to wipe away any excess sealer. Allow to dry 2 hours. If water still absorbs into the grout, a second application is required. - Rust-Oleum Product Support 4

              absorbing water and discoloration to grout
              First coat went on great and dried with no discoloration to the grout… however the second coat changed the grout color in some spots making it look wet even let it dry for 2 days and it still looks the same and the water is still absorbing in grout. I am very disappointed with this product. Now I have to figure out how to get my grout back to the original color from the damage that was caused from this product.

              We need to know more to get to the bottom of this Kathy. Rust-Oleum Miracle Sealants 511 Spray-On Grout Sealer can be recoated. A simple test can be conducted after the first application has dried for at least 2 hours by applying water droplets to a section of grout and seeing if the water absorbs (darkens). If so, a second application is required. If multiple applications are required, wait at least 2 hours between applications. Give us a call at 800-350-1901 so we can hear more about your application and try to make things right.

                Surprised at how easy the product worked. Loved the spray shape as it easily covered the area I needed protected. The price was very acceptable. I use it on decorative rock around my pool and it works perfectly.

                This is the only grout sealer that I use. Great at making grout more water resistant for years to come.

                Easy to Use
                We've used this product before on tile jobs, and it came recommended to us from a tile installer. This is a very simple, easy-to-use, spray on product. You just point it at the grout line and start spraying, covering it thoroughly. It dries quickly and after 3 years on one job, it's still working great, preventing stains and dirt from discoloring the grout. Any overspray on the tile surface won't hurt anything, but if you're concerned about it, it wipes off easily when wet. This product has only one downside, and that is the price. It tends to run on the expensive side. However with the good performance, ease of use and durability, it's still worth it. Highly recommended!

                Easy to use spray on grout seal recommended by professionals.
                Easy to use grout seal recommended to me by professionals. This is my go to product. It sprays on super quick and easy, seals great, and doesn't leave thick residue on the adjacent tile. A bit pricey but worth the money.
