Siloxa-Tek 8500 Ultra Concentrate - 1 Gallon (Makes 5 GALLONS) Penetrating Concrete Sealer Water and Salt Repellent. Clear Water-Based DOT Approved Silane/Siloxane for Concrete Brick Masonry & Pavers

I did a lot a research on concrete sealers before buying the Ghostshield Siloxa-Tec 8500. Even though this stuff is quiet expensive, I decided to give it a try. I bought 2 of the 1 gallon concentrates. Using the online coverage estimator, I thought I might need a little more than the 2 gallons, but I decided to start with that much to see how far it would go.I prepped my concrete by using a leaf blower first, then a pressure washer the day before. The morning of the application I used the leaf blower again to clean it again. Then I started by using an empty one gallon distilled water jug. I filled it with 3 cup of Siloxa-Tec 8500, then added 12 cups of distilled water. This gave me about 3/4 of a gallon of solution. I dumped it into a gallon pump sprayer to apply.My concrete sections are about 12' X 12'. At first I sprayed to solution on one section and waited to 5 to 10 minutes as instructed, but the solution started to dry pretty quick, and the instructions said to apply wet on wet. Also, I think I applied it a little bit heavy to start out, because I did have some areas that puddled a bit. I used a car wash brush that has an extendable pole to spread the puddled solution and it worked well.After experimenting a little, I found that it worked best to apply the first coat on the 12'X12' section then immediately apply the second coat. I also found it worked best to pour the gallon of mixed solution into the sprayer, then mix another gallon and have it ready to go, so you don't run out of solution part way through the application process.I have about 3000 square feet of concrete. I did the application over 3 mornings in early June. Each day it took less than 2 hours including prep and cleanup to apply the Siloxa-Tec 8500. Almost immediately after application any water that got on the concrete would bead up and roll off the concrete. The 2 gallons of concentrate treated all the concrete I was planning on treating and I have enough left over to treat my 30'X30' basketball court and large front porch. So far I am very pleased with the Ghostshield Siloxa-tec 8500. Hopefully it last a long time.

Easy to apply, follow directions and all worked seamlessly. Great product!

First time using this formulation from Ghostshield, but so far so very good. In the past I have applied the 9500 version with very good results. During my latest maintenance project; I did some more in depth research and it lead me back to GhostShield. For one the 8500 or 8500 series is formulated for my region that gets all for seasons and in the application that I applied it too it will be exposed to freezing temperatures along with road salt. Another key seller for me was the price. Initially the concentrated version is a bit steep but when looking at the volume of active sealer you can apply after diluting it it is not too more expensive than some of the bargain versions which do not have as clear of application, contents of formula, or guidance for best practices when laying down.One key note, and this applies to any sealer, is preparation. I did some very extensive preparation as per guidelines on the website and instructions which included removing any oil stains, debris, and pressure washing the entire surface using a mild cleaner. I did apply a two coat application which is critical for complete coverage. Timing wise, it is very important to monitor temperatures and forecast of rain. I applied the sealer in the early hours of the morning to ensure it has ample time to saturate and penetrate the concrete and not flash dry under higher temperatures. At just over 36 hours I had a pretty hard rain. It was amazing at how the concrete did not discover from water absorption and the water just beaded up and remained for virtually an entire day before I went out and swept it off.We shall see how well it holds up come a full year and winter cycle. But overall I was very happy with the application and initial results!

Very easy to use, spreads well just pricey

The media could not be loaded.  Works as advertised. Easy to apply using a hand pump air sprayer. 2 coats as directed. Surface does not get slick when wet like with other top coat sealers. Curious how long this will last with the P.N.W. rain. Next time I would rather buy the 1 gallon containers to avoid needing to convert ratios for my 1 gal. pump. All in all, great product, easy to use, with clear results. Would highly recommend

So far it has worked great. Application was very easy, had to adjust amounts since I only mixed one gallon at a time. Applied using a sprayer and had no issues.

Works good for four weeks and then basically it is of no use. Will not protect limestone from any stains and no waterproofing effect. Bought 4 gallons and wasted $300.

The product was super easy to use. Followed mixing directions and added to my sprayer. 24hrs. later I tested a small area and it beaded up beautifully! Super happy with the results.
