Question: What is the usable shelf life after it's been opened?
Document: used in on shower floor and walls. very repellent.also used it on stone kitchen counter (pietro cardosa). SOOOOOO much better than what we'd used previously (whatever was on the shelf at big box home store -- which actually pitted the stone a bit).also used it on natural cut bluestone. excellent water repellency. stone color didn't change in the slightest.
worked great.
Wish I knew about this sealer when I first installed my Marble Counter tops. It works better than the big giant name brand (which does not work)  due to the other brands failure I still had etching on Marble. Miracle Seal penetrates the stone well and holds up well also. I put on second coat a few days after first just to get it built up in stone. I will use again
We just had light colored granite counter tops installed in our kitchen. The granite was sealed twice by the installer, once at manufacturing and again at install. Water still would seep into the granite and leave dark spots especially around the sink area. Although the marks would eventually dry and color would return to normal it showed that liquid was still penetrating. We would also get ring marks if a glass of water was left on the counter. One application of 511 and problem solved.
We had no idea what it was coming from. Then we had thanksgiving and used the counter as a buffet for the food. The food spills sat on the concrete surface for maybe 1-2hrs before being cleaned up. We have stains everywhere. Now what!! I would not recommend this product.As advertised it did not alter the color of the concrete and it does appear to repel water fairly well. Use at your own risk I guess.
Very impressed so far!Others have said this stuff last 2-3 years on countertops. I will probably just reapply every year to make sure I never have any problems.I only used about half the container for my countertops and I have a fairly large island.
Used this product on our polished concrete countertops and now we have stains everywhere.After making our new concrete countertops, we needed a way to protect them against staining. We thought we would try this since it was USDA approved, had a 20 year warranty and had good reviews. We applied precisely as directed on the label using 3 coats on one of our slabs and two coats on the rest.
Used this on my white cararra marble counter tops. Excellent product. Did not change the color of the marble. Easy and quick to apply. Great results.
Unfortunately this Miracle Sealants 511 QT SG 511 Impregnator Penetrating Sealer, Quart carefully applied after we let the unprotected highly water permeable grout dry back to its original tint and look did not do any better. We are highly very much disappointed in both the shield product that was paid for to have been mixed in and in the miracle sealants 511 that we bough to remedy the problem. We are getting tap danced by the contractor and the product did not do as recommended to keep the grout from rapidly sucking in moisture.
This product worked well to seal the granite counter tops in our kitchen. I had been putting it off for months because it seemed like too much work. The hardest part is cleaning, really thorough cleaning, of the granite prior to sealing. Once sealed it shines and makes wiping up spills easy. Good product!
Answer: no
