Siloxa-Tek 8505 Ready to Use - 1 Gallon Penetrating Concrete Sealer, Water, Salt & Oil Repellent

This was the best sealer after a year. No issues with rain and ice.

I decided to purchase the 8505 for some 90 year old chimneys that i wanted to seal. I had been having a leak that i narrowed down to either coming from one of my chimneys or it's flashing. Unfortunately I sealed them both(chimey and flashing) at the same time so it will be hard for me to ever know where exactly the leak was coming from and what stopped it. Anyways, the 8505 was easy to apply(i brushed it on) and ready to go out of the container(Ready to Use), no mixing. It's about like using a water based poly coat. I tried to follow the directions best I could and got it on, 2 coats, about 24 hours before rain came. It says it takes about 7 days to fully set in. We had several rains the next week and the brick stayed sticky to the touch. After about a week, it didn't alter the look of the brick unless you got up close. You can see some haze and tell it's coated, especially picking at the brick and mortar, it wouldn't chip off like would before. I haven't had any leaks since applying it. It's been a few weeks know, and we've had plenty of rain in TN. I would recommend trying this, it of course depends on what your using for. But for about 70 dollars this stuff seemed like the best quality i could find for the price and like I said it's easy to use and water based. I used it on two smaller chimneys and have a lot left. So I guess I need to find some more concrete to seal.

I used this product on our concrete porch which is more than 30 years old. I power washed the porch and let it dry well before application of 8505 in March, 2020. I used a brush to apply and did 3 coats but drying overnight between each application. The second and third applications were progressively more difficult to apply because the concrete became water resistant after the first application, as expected. The porch appearance did not change after application.Thus far the product has performed as expected. The porch is water resistant. But I am not sure about salt and stain resistance because I have not deliberatively tested these parameters. Also, I cannot comment on the long term effectiveness of this product. Overall, I gave 4 stars only because it is too early to conclude about the quality of this product.

Applying this stuff is easy. I used a 3/8" nap roller. Just read the instructions, apply in the temperature range they recommend (i.e. not the dead of winter), and you're good. Seeing is believing, so check out the photos. One photo shows when the product is wet. One shows what it looks like after it dries, and the third shows that the hydrophobic properties work even over cracks! I waited a week before testing that part since the instructions say that part can take time to form.It's really everything that comes before applying this product that might suck, which in my case, is the following:I rented a large concrete grinder from Home Depot, resurfaced the concrete, bought a concrete grinding disk for my angle grinder to resurface the edges and corners the larger grinder couldn't reach, and bought dremel bits to get all the way into the corners. Any time you grind concrete, you want to WET grind. It keeps dust down and keeps you from ruining the grinding disks/bits you're using. As a result, the room will turn into a dusty, muddy mess (the walls too).So, I ended mopping and tooth-brushing the room over and over and over for hours until all of the dust/debris was up and the mop water stopped turning dark brown.Now I have a beautiful, sealed floor that will stay beautiful! Great product.

I put this on a month or so ago after scrubbing my 3 month old patio concrete with a cleaner. I was having bad stains from leaves. After putting this on I can wash the leaf residue off with a hose without any lasting stains. I put this in a 5 gallon back pack sprayer I had and application was super easy and fast. It didn't change the appearance of the concrete. I have too small kids so I wanted to make sure what I used didn't make the concrete slick and this did not change the texture or grip of my brushes concrete at all. I am overall happy with ghostshield. It has only been on for about a month so I can't speak to durability but it doesn't seem like it will be an issue.

Sealed my Garage, Driveway, sidewalk and Patio.I was able to put this to the test right away. After sealing my patio I moved my smoker on to it. In that process I didn’t know my drip pan was full and grease spilled over my patio. Amazingly enough I just needed a hose to spray it off.Love it when it rains also. Everyone’s cement looks wet and ours looks dry.

I have used so many different concrete sealers and this by far is my favorite, the water just beads right off and it was so easy to apply!!!!! The price to me is very fair too, I've spent more than this on some sealers and they don't protect against oil either. I will be buying more in the future!!!!!

We tried it with a roller goes on thick and than we tried to spray it on we felt spray it was better and easier so by rolling part of it on we ran out so had to order more
