Miracle Sealants 511 Impregnator Advanced Penetrating Sealer for Countertops, Stone, Tile & Grout, Pint

I recently used Miracle Sealants 511 Impregnator on my tile project, and overall, I’m really pleased with the results. The application was straightforward and easy; I just brushed it on, let it sit, and wiped off the excess with no issues. There was hardly any odor, and cleanup was quick. Most importantly, it actually works as described. Water beads right up on the surface, and I’ve noticed that dirt and stains don’t stick to my grout like they used to. It gives me peace of mind knowing my floors are protected. The only thing I noticed was a slight change in the color of my grout. It went from a true tan to more of a yellowish tan after sealing. It’s not dramatic, but if you have lighter grout, it’s something to keep in mind. Still, I’d recommend this product for anyone looking for an effective and easy-to-use sealer.

Great! Did the job!

I’ve been using Miracle Sealants 511 for a while now, and overall it’s a very solid product. It goes on easily, absorbs well into stone and tile, and provides noticeable protection against water and everyday stains. After application, the surface looks natural not overly glossy or darkened which is a big plus. The sealant definitely does what it promises, but the price is a bit on the higher side, and proper ventilation is important because of the strong smell during application. With that in mind, the performance and durability still make it worth it. I’d recommend Miracle 511 to anyone looking for reliable, professional grade protection, just be prepared to follow the instructions carefully for best results.

Used Miracle Sealants 511 Impregnator on a new bathroom renovation. Applied on both grout and ceramic tiles with a paint edging applicator. Worked great. Followed the instructions and wiped everything down after the 3-5 minute wait window. It is a clear product so there is no tint to worry about. Water bead up and is easily wisked away with a squeegee. Would recommend the product to anyone.

The 511 Impregnator Sealer from this seller is an excellent value when compared to local stores who sell the same product. My intended application for the sealer is to seal limestone (white) blocks for prevention of moisture absorption. The blocks (exterior yard application) look great when first set but are quick to absorb moisture, and over time black mold appears which cannot be removed. Consequently, the beauty of the garden is quickly tarnished once this occurs. I called the manufacturer of the 511 sealer and explained that my intended purpose is to apply the sealer to exterior limestone blocks to prevent moisture absorbtion in an outdoor setting. They said it would achieve my purpose and suggested using at least two coats of the sealer. I first brushed the blocks with a stiff bristle brush to remove surface dust and then applied the sealer liberally to the limestone blocks. I allowed several hours between coat application on a 80 degree day. The optimal method for applying the sealer is with a 3 inch cheap paint brush dipping sealer out of a one quart plastic paint container. The sealer goes on effortlessly. I coated the top and one exterior side. I coated 60 linear feet x 8" height of limestone blocks using the one gallon product. I had over a quart of sealer left upon completion. I had a concern that the blocks would yellow or darken after the application. However, I was pleased that the original white was maintained after the sealer dried. I will follow-up on this 12/17/21 review in May / June 2022 for the purpose of how effective the product was for maintaining the original appearance of the limestone. May 2024 I am following up on a review done in 2021 concerning the performance of the 511 Impregator sealer. I applied this great sealer to limestone blocks some three years ago and amazingly no fungus, mold or other has grown on the limestone blocks placed in my wife's garden. They have retained their nice white appearance over the years. I highly recommend this sealer.

My granite kitchen countertops were absorbing liquids and becoming stained sometimes. They have become 100% waterproof after using this product.

Honest review. Our bathroom fitter didn't seal our grout lines. Water was absorbing into the grout and leaking down back of bath. Bought some grout sealer from Topps tiles and applied 4 coats but water was still absorbing in. Searched for best grout sealers and came across this. Bit wary as it has a cancer and reproductive warning on the label and on Amazon description. I opened the windows and wore a face mask and latex gloves. Tipped some product out into an old double cream plastic pot and applied on the grout lines with a paintbrush. Left for 10 minutes and wiped off excess with kitchen towel. Reapplied another coat after 4 hours and left to dry for 36 hours. Used shower and the results were amazing. You can see the water beading up and running over and down the grout lines and tile faces. Absolutely amazing product. I would definitely recommend to anyone who wishes to seal their grout. Dearer than all the other ones but obviously you get what you pay for. The bottle will last a lifetime!!! No more leaks!!! Yay!!!

A bit slow delivery, priduct arrived well-packed. When applied to seal the grouting, it has no difference than before. It does not meet my expectations for sealing grouting properly, also does not create waterproof film. Probably my expectations were too high, due to the high price of the product.

Works well, create a great grout and tile protector. Smells very strong so a well ventilated room is needed.

A very Good Product. The seller also has given good support. Used in on sand stone tiles in the garden.
