Happy to clear things up, Brenda! Since this is a listing for Rust-Oleum RockSolid 20X Deck Resurfacer that is pretinted, we do not recommend adding any additional tint or mixing it with any other coating. Doing so can degrade the product's performance or prevent it from properly drying. - Rust-Oleum Product Support 3

    Judy, we got you covered! Rust-Oleum RockSolid 20X Deck Resurfacer can be applied to broom-swept or porous concrete surfaces. It will not properly adhere to smooth or floated concrete. Additionally, the product is also not suitable for use on surfaces that will have vehicle traffic, such as driveways or garages. - Rust-Oleum Product Support 10

      Answer This Question

      We are happy to clear things up! Rust-Oleum RockSolid 20X Deck Resurfacer may appear slightly different in color compared to RockSolid 2X Deck Stain, as each product is formulated for a different purpose and build. The good news is that RockSolid 2X Deck Stain can be applied over the 20X Deck Resurfacer. If more than 5 days have passed since applying the Resurfacer, we recommend first applying a fresh coat of Rust-Oleum Deck Start Wood Primer. This will help promote proper adhesion and ensure the best overall results. https://www.homedepot.com/p/Rust-Oleum-RockSolid-1-Gal-Deck-Start-Exterior-Wood-Primer-Clear-312283/307428127 - Rust-Oleum Product Support 10

              1 Answer | 
              Answer This Question

              Happy to help! Before applying Rust-Oleum RockSolid 20 Deck Resurfacer and Rust-Oleum Deck Start Primer to the deck, it is essential that anything loose is removed from the surface. If the existing primer and paint are soundly adhered, then they do not need to be removed. The use of the Deck Start Primer is essential with the 20X Deck Resurfacer to ensure full adhesion. https://www.homedepot.com/p/Rust-Oleum-RockSolid-1-Gal-Deck-Start-Exterior-Wood-Primer-Clear-312283/307428127 - Rust-Oleum Product Support 3

                    We followed the instructions to a tee, then ended up doing two coats because of how much you have to buy for good coverage. Easily $1000 project and we would have rather probably just replaced boards. Showed signs of weathering about 6 months in. Photo shows after 2 years....

                      Not a full gallon. 3.6 quarts is all you get
                      This product is way over priced and they claim you get a gallon but it is 3.625 quarts is all you get. Almost 10% less than they claim. It works well. You MUST use the 20x roller for optimal results. In one area where I brushed it on it quickly wore off and was no good. The rolled on with their course 20x roper is superb. I want my 10% discount for the false size claim!!!

                        Sorry, can't recommend this
                        First of all, it's crazy expensive. But....after doing some research and talking to a local painter, it came fairly highly recommended. Unfortunately that was not my experience. My deck was old and covered with several layers of old paint, so I had it blasted to get down to clean wood. After they cleaned it, I washed it with the Rocksolid deck wash and allowed it to dry completely which happened fast since it sits in the sun. I primed it twice because the first coat soaked in quickly and waited until the next day to paint. I used a tarp on my railings to keep any dew off, but there was none and no purple-ish color so it should've been dry. Then came the application, it went down on a cloudy day, so the deck wasn't hot to the touch. This stuff's thick. Really thick so it took a long time to apply and get a nice coating on the deck and fill in any large-ish cracks and keep it mixed. As a prior review noted, the roller doesn't hold much so you have to go slow or risk pulling it off. My deck is just under 500 square feet so again, it took a while. Let it dry for a week as we left that night. Looked great once it was done and lasted the summer with the traffic from 2 adults, 3 kids, 2 dogs and a good number of guests. Then came the next spring. The pics below are what I found when I opened up in the spring and are about what it looks like now, minus some more paint. It basically came up in strips and bubbles up when it gets wet, so I'm having it blasted off and will try a good epoxy laid down by a pro. I was hoping for more than one season out of it, but the response from Rustoleum was to re-coat and it's too expensive to do every year. Can't in good conscience recommend this to anyone unless maybe if a pro puts it down to be sure it's done right or it's done on new wood, but even the newer planks on my deck bubbled and stripped off so I don't know.

                          Disappointed
                          I watched all of the Rust-Oleum videos to make sure that I applied this product correctly. I purchased all of the recommended supplies, from the deck cleaner to the roller cover. I painted Monday morning, & then let it dry (48 hrs before rain). I noticed that it didn’t look great as it dried—the color was uneven and it looked bubbly. It rained Wednesday, and after the rain cleared I checked the deck, & m I am devastated. The paint is not hard, but gooey and bubbly all over. I can see that it is going to peel. This wasn’t a cheap product, & I expected a much better finish. Not sure what I’m going to do now.

                            This is my 2nd time using Rustoleum on my deck, I’ve previously used 10x which was very durable for many years. The 20x product is thicker and needs to be applied much quicker. It is great for filling in deck cracks and exposed nails with a nice textured finish. It does get a bit hot on sunny days, so make sure you have on shoes.

                            I had the product professionally shaken at Home Depot 2x longer (per the guy behind the counter). The product is like spreading frosting it is SO thick. The product is full of a sand like filler/texture that will not spread evenly, not by recommended roller or brush. Some parts of the deck are VERY textured and some parts are shiny with no texture at all. It does fill in the cracks, that it does do. I covered a 15 year old deck with it and a newly constructed wood ramp. The product could not evenly coat either. The finished product looks absolutely terrible.

                            That is not what we like to hear! Our RockSolid 20x Deck Resurfacer is an ultra-thick deck coating, and must be applied using the specialized companion roller cover. While using this roller, the coating should be pushed out and spread, not applied in the back and forth motion typically used with normal paint. If you would like to give us a call at 800-373-6333, we will be happy to help with tips to get the application looking the way it should. https://www.homedepot.com/p/Rust-Oleum-RockSolid-9-in-20X-One-Coat-Roller-318223/307428130 - Rust-Oleum Product Support 2 Rustoleum

                            After 3 yrs of repeatedly scraping, sanding, priming & painting our wooden porch floors only for the paint to peel off again & again, a friend of ours told us about RockSolid. After just one coat, it was evident that we may have found the product of our porch dreams. It is waterproof, feels great to walk on, and I believe will make it through the Southern Illinois seasons just fine. The product looks great, too.
