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.

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

5 gal. S-40 Water Repellent Sealer is rated 4.6 out of 5 by 15.

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.

Was dried in about 4 hours but didn't drive across for 24 hours. I would definitely recommend at this point. Will depend on longevity.

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.

I applied it only a month ago so it is difficult to make a complete assessment. {It went on very easily but I used a four inch brush.} However , it does seem to repell water on most portions of the surfaces I used it on. It dried very quickly on one porch so I plan to try a second coat. I spilled some antifreeze on the patio and it was not repelled as well as water. One side note, some spots on the patio have darker splotches that I attribute the OKON material. [ I'm not exactly why that happened unless the surface was not in the direct sun as much as other sections I coated.]

Product went on easy with a garden sprayer and then back rolled puddles after 10 minutes with a 3/8" nap roller per instructions. Got approximately 110 square feet per gallon coverage on a broomed finish concrete driveway. Have not had much rain since the application, but what rain we did have the water beaded up nicely on the driveway. Time will tell but for now I am very pleased.
