Questions & Answers

I find contradictory answers on this website to a question asking of the difference in S20 vs. S40?? Anyway, my application is a new exposed aggregate concrete patio. S20 or S40, and why? 1 or 2 coats necessary? Coverage for this application? Is it advisable to apply this sealer to my patio perimeter wall consisting of cast concrete stones?
Asked by: Mike
Thank you for reaching out, Mike! Rust-Oleum Okon S-40 Water Repellent Sealer is recommended for use on more porous concrete and masonry surfaces. Rust-Oleum Okon S-20 Water Repellent Sealer is recommended for use on dense concrete and masonry surfaces.. The S-40 is great for exposed aggregate! For textured surfaces, we recommend a second coat and to apply it while the first coat is still damp. - Rust-Oleum Product Support 3

My driveway was stained & sealed many years ago. I would like to stain it a different color now & reseal. Do I stain it first or apply this sealer first? Or can this sealer be colored to do both at once?
Asked by: MS
Great question! Rust-Oleum Okon S-40 Water Repellent Sealer is intended for use on bare concrete and masonry surfaces only and we do not recommend tinting this product. Instead, Rust-Oleum Concrete Stain and Sealer may be a better fit for your application. The previous stain would need to be removed to ensure proper adhesion. https://www.homedepot.com/s/rust%2520oleum%2520stain%2520and%2520sealer?NCNI-5 - Rust-Oleum Product Support 3

What do I use on painted basement walls to waterproof?

Asked by: Johanna
This product is designed to be applied directly to bare concrete and masonry surfaces only. Rust-Oleum Seal-Krete Heavy-Duty Concrete & Masonry Waterproofer may be applied over well adhered painted surfaces.

5 gal. S-40 Water Repellent Sealer is rated 4.4 out of 5 by 8.
Rated 3 out of 5 by from Did my research on line and decided to go with... Did my research on line and decided to go with the penetrating silane/siloxane sealer. concretesealerreviews.com gave good reviews on this product. Application with a pump-up garden sprayer (once you get the correct nozzle) and back rolling was very easy. And so was cleanup, easier than cleaning latex paint. There were no problems with solids separating; we just pick up the bucket, shook it, and poured it into the sprayer. When we finished, we removed the lid from the bucket and there were no solids left. Only time will tell if it was worth almost $400.

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.

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.

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.

Did 2 coats using a 4 inch nylon brush (second coat being extra generous). I am very satisfied with the results. Water beads up as it should during rain. Gives the homeowner a sense of satisfaction to see the product working as it should. Great value for the price paid for a 5 gal. Definitely get the 5 gal.
