Rainguard Water Sealers Concrete Sealer, Penetrating Protection Against Water and Salt Damage, For All Concrete Surfaces, Silane/Siloxane Waterproofer, Natural Finish, Ready to Use, 1 Gallon

Wonderful stuff. Dilutes easily and doesn't lose its coating strength. Used it on a cinder block-type fire pit and has held up well in direct sun and weather.

This rain guard sealer does appear to repel the water. I have not had a chance to see how it does will oil leaks yet I will purchase more to finish up my driveway. This was very easy to spray on and does not change the look or color of your driveway . In the picture, you can see where I applied it. This was after a rain.

Sprayed it on new cement couple months after pouring. Not sure if it's the sealer or cement but since cold weather arrived my sidewalk hasStarted to deamination and is gritty.Application was easy.

Easy to use

Used it to seal paver blocks still has A lot of roughness so I need to see after it rains to see if it works.

Even more important than whether it protects, will it change the look of my pavers? Definitely not! I was concerned that my blocks would look shiny or darker than they did before I used the sealer. I was relieved to see that when the sealer dried, it was completely invisible, unnoticeable. I used the sealer just for the cap stones on my retaining wall and around my landscape beds. I also used it on my chimney cap. I did the chimney cap first and I used one of those cheap foam paint brushes. That was not the best way to apply it. The directions say to use a garden sprayer but I felt there would be too much overspray and I would run out of product. Instead, I used an empty spray bottle of kitchen cleaner. It was a little tiring with all that trigger pumping but I was able to lay down a nice even coat. I went over it a few times to make sure the stone was saturated pretty well. It is important to get that "second coat" on before the first one dries, overwise it will repel itself. After allowing a day for drying, I noticed as I was watering my landscaping that the water was beading off the caps pretty well. If there are few spots where it wasn't beading as well it is probably because I didn't saturate that spot enough. Bottom line: I am very happy with this sealer. My cap stone now sheds water instead of absorbing it and it look exactly the same as it did before the application. Using a hand sprayer worked great for my job but it would take forever to do an entire driveway that way!

So impressed withthis sealer. For under $20, you cannot beat it. I tried it on two small portions of my back patio cement. Was amazed to see that water from the rain actually does bead up on those two small sections. I also used it in my basement on the walls to make sure no moisture leaks in. Very happy with it.

Worked as advertised, but I miscalculated how much I would need for two coats. Would buy this again.
