I do not own an airless paint sprayer that is recommended to apply the sealer. Can i just roll it on with paint roller?
Asked by: Rjcvg
Yes, you could roll it but it is faster to use the sprayer. Even using the sprayer you still must roll it to eliminate puddling and get an even application.

I'm confused about time to recoat for a patio. The product as listed as dry after 8 hours and you can't apply another coat when dry. It also says to apply another coat when it is still damp. Are we talking minutes, 1 hour, 8 hours?
Asked by: pickerflicker
The product repels water. If you let it dry it will repel subsequent coats. So, what they're telling you is to apply a second coat as soon as the first soaks in. That was very fast on my driveway, less than a minute on most areas.

Will Okon S-40 or S20 help to protect oil stains on garage floor?
Asked by: kd
We like how you think! Rust-Oleum Okon S-40 is designed to waterproof the surface, but will not provide proper resistance to oil stains. We need to know more about your application to make the best recommendation for you. Please feel free to call us at 888-683-5667 to discuss further. - Rust-Oleum Product Support 5

I used a regular pump-pressure type garden sprayer with a fan tip after cleaning the concrete with a pressure washer. When dry, the material is totally clear - leavin the appearance of plain concrete. I can't comment on the durability as it's only been two weeks since I applied it and it's been reined on only once. If it lasts as long as advertised, it's a 5-star.

Rated 5 out of 5 by from S-40 Water Repellent Sealer - Excellent Product The S-40 water repellent sealer was very easy to use. I sprayed it on the driveway using a hand held sprayer. It went on easily and covered the area quite well. It did not change the color of the concrete in any way that I can tell. The rain beads up on the driveway better than it does on my waxed car. I am very pleased with the way it covered, how easy it was to apply and how it seems to have sealed the driveway. A bit pricey but will be worth it over the long haul.

Rated 5 out of 5 by from Best Deal out there (Concentrated) This product is 40% silane/siloxane and is the best deal on an active ingredient basis. Most of the other products out there are just watered down versions with only 5%-20% active ingredients. S-20 was the next best deal I could find. Be sure to look at the concentration of ingredients on the Spec sheet so that you don't end up just buying water. It works well for beading and only slightly darkens the aggregate.

I opened the 5 gallon bucket of this S-40 and used a drill mixer to stir it. It already seemed like it was mixed. I poured it into a pump up garden type and deck sprayer and sprayed it on the driveway. It sprayed on really nice.
