## Description

Siloxa-Tek 8505 Ready to Use - 1 Gallon Penetrating Concrete Sealer, Water, Salt & Oil Repellent: desertcart.com: Tools & Home Improvement

Review: Easy to apply, Invisible to the eye, Impressive hydrophobic properties - 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.
Review: Siloxa-Tek 8505 'Ready to Use' - 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.

## Questions & Answers

**Q: I am considering this to seal our pool deck. Does this sealant make the desk slippery when it get wet?**
A: I used it on a concrete driveway. It doesn’t make it slippery. Not sure what the material of the pool deck is.

**Q: can this be used on outdoor concrete countertop?**
A: I did use this product on my outdoor BBQ concrete counter.  I put two coats and waited 24 hours before using

**Q: Can i stain the concrete using this sealant? If so, is it preferred to stain before i seal?**
A: This is a sealer and as such it will most likely darken your concrete to an extent but that depends on your concrete and how it was finished. If you want to stain the concrete, I would do it before sealing as any sealer will prevent a subsequent finish from penetrating very well. You may be able to add color to the sealer but contact the mfg. for their advice. I was a concrete finisher and most times, coloring concrete except for interior applications is kind of dicey. Good luck

**Q: Does it come in 5 gallon buckets?**
A: No it does not. Only 1 gallon and 55 gallons
